We are all the product of a reproductive process, yet reproductive biology, or the study of the processes and mechanisms involved in reproduction, is not well understood. Deepening our understanding of reproductive biology is crucial to advancing assistive reproductive technologies (ART) and advancing our collective comprehension of inheritance and evolution. Our guests for this episode are a couple, and we mean a literal married couple, of reproductive biology experts. Dr. Pavla Brachova and Dr. Nehemiah Alvarez, both working in the Eastern Virginia Medical School's Department of Physiological Sciences. In their collaborative work they aim to better understand and characterize the role of RNA and cellular events that impact ovarian function in women. We learn about their work with oocytes, which are single cells that grow and mature within the ovary and once fertilized provide the foundations of an embryo capable of maturing to a new individual. They outline how they use digital PCR (dPCR) and other methods to monitor RNA regulation in single cells and how progressing this work and lead to potential RNA-based therapies. In Cassie's career corner we hear childhood stories from each guest and learn about their respective career paths, which eventually collided and merged. They share insights on the importance of having mentors experienced in your field, the challenges of shared job searching, and the joys of collaborating as a couple with shared scientific interests.Visit the Absolute Gene-ius page to learn more about the guests, the hosts, and the Applied Biosystems QuantStudio Absolute Q Digital PCR System.

A new editorial paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 15, entitled, “Epigenetic aging in oocytes.” Aging-related phenotypes span many different tissues and cell types, and start to occur at different ages - a different typical age for every cell type. In their new editorial, researchers Peera Wasserzug-Pash and Michael Klutstein from The Hebrew University of Jerusalem discuss one of the earliest occurring aging events in the human body, which is the beginning of female reproductive aging and deterioration. The clinical cut-off for advanced maternal age (AMA), a condition associated with poor reproductive outcomes, is 35 years old. “The early onset of reproductive aging poses a significant challenge to clinicians since a global consistent increase in maternal age at first birth has occurred in recent decades, effectively shortening the available time window for reproduction [1].” As the rate of patients with advanced maternal age rises, and with it, the number of patients in fertility clinics, so does the necessity for a fundamental understanding of the reproductive aging process. In recent years, it has been established that there is a substantial dominating influence of oocyte quality loss on age-related fertility decline. This is best demonstrated by the rise in IVF success rates in reproductively aged women when they receive an egg donation from a younger woman. Oocyte quality loss is characterized by diminished cellular function and an increased occurrence of chromosomal nondisjunctions. “Our recent publication [4] addresses the question of additional, epigenetic mechanisms that lead to the occurrence of age-related oocyte quality loss.” DOI - https://doi.org/10.18632/aging.204976 Corresponding author - Michael Klutstein - michaelk@ekmd.huji.ac.il Video short - https://www.youtube.com/watch?v=KHOVKKaJykY&t=45s Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.204976 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, oocytes, heterochromatin, epigenetics, maturation About Aging-US Launched in 2009, Aging-US publishes papers of general interest and biological significance in all fields of aging research and age-related diseases, including cancer—and now, with a special focus on COVID-19 vulnerability as an age-dependent syndrome. Topics in Aging-US go beyond traditional gerontology, including, but not limited to, cellular and molecular biology, human age-related diseases, pathology in model organisms, signal transduction pathways (e.g., p53, sirtuins, and PI-3K/AKT/mTOR, among others), and approaches to modulating these signaling pathways.

This week we're talking about "advanced maternal age" which is the medical term for women having babies over the age of 35. The real problem here comes down to oocyte aging, or aging eggs, which is related to poor ovarian reserve. We'll talk about why egg quality declines with time, what sort of testing your doctor will run, the difference between poor ovarian reserve and advanced maternal age, the options for women trying to get pregnant, lifestyle and supplements for oocyte aging and to increase egg quality, and also advanced paternal age, or old sperm. 00:00 - Intro 00:28 - Why egg (oocyte) quality declines with time 03:07 - Testing for oocyte quality 04:56 - Poor ovarian reserve vs. advanced maternal age 06:57 - Options for women with oocyte aging 08:36 - Lifestyle and supplements for oocyte aging 11:11 - Advanced paternal age 13:49 - Outro Here's the video version of Dr. Kate and Dr. Amy talking this one through.

Abstract: Super-resolution (SR) microscopy is a cutting-edge method that can provide detailed structural information with high resolution. However, the thickness of the specimen has been a major limitation for SR methods, and larger structures have posed a challenge. To overcome this, the key step is to optimize sample preparation to ensure optical homogeneity and clarity, which can enhance the capabilities of SR methods for the acquisition of thicker structures. Oocytes are the largest cells in the mammalian body and are crucial objects in reproductive biology. They are especially useful for studying membrane proteins. However, oocytes are extremely fragile and sensitive to mechanical manipulation and osmotic shocks, making sample preparation a critical and challenging step. We present an innovative, simple, and sensitive approach to oocyte sample preparation for 3D STED acquisition. This involves alcohol dehydration and mounting into a high refractive index medium. This extended preparation procedure allowed us to successfully obtain a unique 2-channel 3D STED super-resolution image of an entire mouse oocyte. By optimizing sample preparation, we can overcome the limitations of SR methods and obtain high-resolution images of larger structures, such as oocytes, Knowledge of which are important for understanding fundamental biological processes.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.12.06.519314v1?rss=1 Authors: Briley, S. M., Ahmed, A. A., Jiang, P., Hartig, S. M., Schindler, K., Pangas, S. Abstract: In mammals, meiotically competent oocytes develop cyclically during ovarian folliculogenesis. During folliculogenesis, prophase I arrested oocytes are transcriptionally active, producing and storing transcripts required for their growth and for early stages of embryogenesis prior to the maternal to zygotic transition. Defective oocyte development during folliculogenesis leads to meiotic defects, aneuploidy, follicular atresia, or non-viable embryos. Here we generated a novel oocyte-specific knockout of the SUMO E2 ligase, Ube2i, using Zp3-cre to test its function during folliculogenesis. Ube2i Zp3-cre+ female mice are sterile with oocytes that arrest in meiosis I with defective spindles and chromosome alignment. Fully grown mutant oocytes abnormally maintain transcription but downregulate maternal effect genes and prematurely activate the zygotic transcriptional program. Thus, this work uncovers UBE2i as a novel orchestrator of chromatin and transcriptional regulation in mouse oocytes. Copy rights belong to original authors.

How does egg freezing reshape our conception of time, aging and fertility? In her new monograph, Freezing Fertility: Oocyte Cryopreservation and the Gender Politics of Aging (NYU Press, 2020) Dr. Lucy van de Wiel explores the significance of egg freezing in re-orienting the temporality of the gender politics of aging. Dr. van de Wiel argues that it is critical to examine the politicized dimensions of egg freezing because it transforms the broader discourses around aging and normative timeline of women's reproduction even though the technology is only accessible for an elite few.  Through a cultural analysis of popular media and documentaries to highlight the role of rhetoric in creating conditions that motivate women in making decisions about their reproductive futures, Dr. van de Wiel criticizes the moralistic boundaries between social and medical utilized by some state actors to condemn women who decide to freeze their eggs for their careers. Dr. van de Wiel also highlights the role of financialized capitalism in refiguring fertility under the investment logic of optimization to speculate on the potential risks posed by anticipated infertility. Egg freezing technology shows us how the biopolitical control of population shifted to managing fertility, which transcends national borders as frozen eggs circulate transnationally for assisted reproduction as well as stem cell research. An incredibly rich and nuanced book, Freezing Fertility would be an invaluable read for anyone who is interested in the politics of reproduction, ART, gendered politics of aging, mortality, life, and regeneration.   Dr. Lucy van de Wiel is a Research Associate at the Reproductive Sociology Research Group (ReproSoc), University of Cambridge. Her research focuses on the social and cultural analysis of assisted reproductive technologies like egg freezing, time-lapse embryo selection and cross-border reproductive care. Da In Ann Choi is a PhD student at UCLA in the Gender Studies department. Her research interests include care labor and migration, reproductive justice, social movement, citizenship theory, and critical empire studies. She can be reached at dainachoi@g.ucla.edu.

Abstract: Background: Oocyte quality decreases with aging, thereby increasing errors in fertilization, chromosome segregation, and embryonic cleavage. Oocyte appearance also changes with aging, suggesting a functional relationship between oocyte quality and appearance. However, no methods are available to objectively quantify age-associated changes in oocyte appearance. Results: We show that statistical image processing of Nomarski differential interference contrast microscopy images can be used to quantify age-associated changes in Caenorhabditis elegans oocyte appearance. Max-min Value (mean difference between the maximum and minimum intensities within each moving window) quantitatively characterized the difference in oocyte cytoplasmic texture between 1- and 3-day-old adults (Day 1 and Day 3 oocytes, respectively). With an appropriate parameter set, the gray level co-occurrence matrix (GLCM)-based texture feature Correlation (COR) more sensitively characterized this difference than the Max-min Value. Manipulating the smoothness of and/or adding irregular structures to the cytoplasmic texture of Day 1 oocyte images reproduced the difference in Max-min Value but not in COR between Day 1 and Day 3 oocytes. Increasing the size of granules in synthetic images recapitulated the age-associated changes in COR. Manual measurements validated that the cytoplasmic granules in oocytes become larger with aging. Conclusions: The Max-min Value and COR objectively quantify age-related changes in C. elegans oocyte in Nomarski DIC microscopy images. Our methods provide new opportunities for understanding the mechanism underlying oocyte aging. Copy rights belong to original authors. Visit the link for more info

Have you ever thought about freezing your eggs? If you're a woman in your thirties, heck, if you're a woman in your twenties, chances are egg freezing has come across your radar at least once. So much around it can feel overwhelming, scary and unknown. How does egg freezing actually work?? How much does it cost? Does it hurt? How old should you be when you freeze your eggs? What are the success rates? How does it affect future fertility?   In this episode - the very first episode of In Her Prime, Talia sits down with Dr. Dan Nayot to learn all about social egg freezing. From the testing that's done, to the hormones you take, to the egg freezing process itself, a lot is explained. For reference, Dr. Nayot practices out of Toronto, Canada so the information provided on things like cost and insurance is based on Canadian stats. That being said, this episode is still immensely relevant to anyone, anywhere who wants to learn more about egg freezing as the process itself remains largely the same wherever egg freezing is done.     The purpose of this episode is to help provide you with more in-depth information on social egg freezing from a medical expert, not to make recommendations on what you should or should not do. Of course, that decision belongs to you. Listen and enjoy, and if you have any questions, comments, or personal experiences you'd like to share, you can do so in our free, private Facebook community, PrimeMates.

Oocyte cryopreservation, or egg freezing, is a viable option for people with ovaries who want to extend their fertility or begin IVF. While it’s becoming more commonplace, the experience is not as simple as it’s sometimes made out to be: hormonal self-injections, frequent appointments, and going under anesthesia are all part of the process. So what’s really involved, and what can you do to make the procedure as smooth as possible? Sophie shares her tips on today’s episode.

Dr Lynn Westphal is CMO at Kindbody, a new model for fertility health care.( They have mobile clinics (the fertility buses) positioned in high traffic areas so women can potp in for a chat and organise a fertility assessment. Their primary group of patients is women seeking to freeze their oocytes, however they offer IVF cycles and a full range of fertility services. Lynn set up one of the first cyropreservation programs for oncology patients back in 1998 at Stanford University. With such an incredible wealth of fertility experience, the conversation with Lynn was enlightening. https://kindbody.com/

SHOW NOTES:  INTRODUCTION: Dr. Damario is the medical director of the Center for Reproductive Medicine in St. Paul, MN; and is a practicing reproductive medicine specialist who earned his medical degree at the Medical College of Virginia, and completed his OB/GYN residency there as well. He then went on to complete fellowships in reproductive surgery at Emory University and reproductive endocrinology at Cornell. We were delighted to have him join us on May 24, 2019, to provide his insights and updates on assisted reproductive technology. CHAPTER 1: ART (assisted reproductive technology) was initially done in rabbit models, and then the first successful IVF birth in humans in 1978. Use of oocyte donation in 1983, a surrogate mother in 1986. Pre-implantation genetic dx in an embryo in 1989, and a single sperm injected in an egg in 1992. These were major breakthroughs. Where is ART these days? There are over 500 clinics in the U.S. that contribute for the most part to the national database on stats for ART. Ultimately, there are over 65,000 live births, and the percentage is now about 1.9% of total babies born now in the U.S.   Forbes.com in 2012, estimated 900,000 approximately conceived persons in the U.S. derived from IVF. That's about 305 people at Times Square bumping into each other on any given day. In 2017, the trend of multiple pregnancies in IVF and ART has come down. This issue has been contentious in the field of ART. Triplets in particular happen less often. Less than 1% from 7% in the mid-1990s. Twins have decreased in rate as well. Oocyte cryopreservation has continued to increase, as it is much more efficient now for donor and fertility preservation. More elective single embryo transfers as well. Indications for IVF include: Tubal factors such as occluded or absent tubes are indications, Male factors, such as severe oligospermia is also an indication for IVF. Advanced endometriosis and failed induction of ovulation, diminished ovarian reserve, unexplained infertility and a variety of specific conditions, such as the need for pre-implantation genetic diagnosis are also indications. Dr. Damario's program treats women age less than 45 with their own eggs and less than 50 with donor eggs. Smoking is a contraindication. BMI is also an issue for patients. Assessment of the woman will include antimullerian hormone (which has key roles in folliculogenesis), basal antra follicle count by U/S (an ovarian follicle in the latter stage of formation) and less often day 3 FSH and estradiol. Sonohysterography or saline hysterography, semenalysis, and sperm penetration testing, cervical canal evaluation, testing for Hep B and C, HIV and Syphilis are also performed ahead of time. How does the treatment phase of IVF work? Pituitary inhibition needs to happen in order to suppress the LH surge before oocyte retrieval. OCPs are given ahead of time to suppress other ovarian cysts, and to help start some of the later fertility medications. Pituitary suppression with Lupron or antagonists, such as Ganorelix. The gonadotropins are given after withdrawal bleeding from discontinuation of the pill and for about 8 to 12 days. Ultrasounds for follicles and estradiol accounts are performed. HCG is then given if all looks well with the above steps. It is similar to LH and then oocyte retrieval is scheduled 36 hours later. This is a precise action so as to not have egg immaturity or have ovulation occur. Embryo transfer then happens on the 5th day, most commonly. Usually then a pregnancy test happens on the 9th day. egg retrieval occurs transvaginally with ultrasound guidance. This is a day surgery procedure, and is generally tolerated well. Dr. Damario shows a short video of the procedure at this time. The embryologist takes the follicular fluid to ID eggs. They are graded for maturity, and they simultaneously prepare sperm. Eggs are incubated, then are exposed to sperm. They are observed the following day, embryos cleave and then on days 3 to 5, the embryo is transferred. A mature egg is actually the largest cell in the human body, and is surrounded by a clump of cells called a corona. Micro-droplet of sperm onto the egg and intracytoplasmic injection of a single sperm injected into the egg can also be done, especially if sperm quality is lower. The embryo is then cultured and grown, with cell division occurring daily and exponentially. A morula, which is many cells, is followed by a blastocyst forming, which is an expansion with an inner cell mass and fluid space. At this stage, the embryo is felt to be doing well. If they're not doing well, the embryo won't be chosen for transfer. Egg fertilization occurs at a rate of about 75%. The embryo is transferred into the uterus with transabdominal U/S guidance as it is placed into the uterus. Little to no anesthesia is required for this. CHAPTER 2: Outcomes are impacted by age to a fair degree, obviously higher (success) in younger women. The older the patient the less likely it will take effect. Cryogenically preserved embryos are doing well in transfer, in fact slightly better in some cases than traditional transfer. Risks of IVF include: multiple pregnancies, ovarian hyperstimulation syndrome, bleeding and infection, which are rare. Adverse pregnancies such as ectopic and miscarriage can occur. There is a possibility of subtle increase in congenital anomalies. Third party reproduction options include: oocyte donation from someone, sperm donation, embryos donated and gestational surrogate. This involves gestational carrier of the couple's own embryo. Oocyte donation is performed win carious ovarian failure conditions in general. Anonymous donors are screened very well, and hopefully in a hormonally synchronized recipient. They will be maintained on hormones through the first trimester in most cases. Oocyte donation has a very good success; especially with the improvement of cryopreservation. In older women, for instance up to age 45, there is good success with this procedure. Beyond 45 yo, there is lack of sufficient data to support doing this. Gestational carrier is indicated when there is no uterus, uterine complications, substantial risk to patient due to other conditions, same sex male couples for instance. Fertility preservation is performed in instances of cancer treatment. These include oocyte, sperm and embryo cryopreservation. These are experimental, but are coming down the pipeline in the future. Fertility preservation is not a guarantee that it will work but the odds do go up proportionate to the number of eggs frozen; although this does decline the older you are. Preimplantation genetic screening: random chromosome abnormalities, or embryonic aneuploidy is screened for more often now. Age of the woman is an impact, although problems can be derived from sperm too, but there is no age impact in men. Embryos can be screened for such things as SC disease and CF. Now embryos are biopsied at day 5, and the trophectoderm (outer layer) is sampled for this. The embryo is the frozen after biopsy. These samples are sent to national labs for this. Usually, affected embryos will not be transferred. Next generation sequencing testing modalities are used commonly now. A significant proportion of anuploid embryos are found now, actually. It appears, for instance, that women who are of older gestational age, are to benefits most from genetic testing. Gestational carrier cases are also good reason for genetic testing, since the surrogate will be taking on a significant risk in carrying the child. CHAPTER 3: Evolving ART.  Major advances have been made in many areas. Cryopreservation, genetic testing and counseling, etc. We're not quite there yet with oocyte in-vitro maturation. Essentially embryonic stem cell therapy is still being done, but more adult stem cells are being used. Mitochondrial transfer therapy for mitochondrial diseases are being done in the U.K.  Germ line gene editing, for instance, to have HIV protection, has come up at a recent conference. This is in the very early stages of development though. Question from the audience: Pre-implantation genetic diagnosis - how many things can be screened for? PGS is still for a limited list of conditions, mostly the disease conditions are monogenic. Sex chromosome reports are also obtained. But, this is not done only for sex selection, especially in fertile couples. When appropriate, this can be chosen, however.  There is a slight chance of error, but certainty is very high. Other questions included freezing of eggs. Not only in dire circumstances such as cancer, but also for women who may want to wait to have children for any variety of reasons. Vitrification is the method used for this now which is essentially "flash freezing" and has been perfected over the past 7-8 years. Also, Dr. Damario mentions that studies show that visualized hydrosalpinx on U/S is associated with poorer IVF outcomes. Salpingectomy can improve chances with this. Cost is also addressed, and of course when insurance doesn't cover the cost of ART, there is a significant expense to the patient. Screening tests are commonly covered by insurance. Finally, Dr. Damario comments on a question regarding egg transfer. Transferring eggs to someone else is not a simple task and is governed by the FDA, much like transplant surgery.  

On this week's episode we speak with Valerie Landis.  Valerie is the host of the Eggology Club Podcast, writer of the Blog Eggsperience and nominee for a WEGO Health Award.  Valerie discusses her decision to undergo cryopreservation of own eggs, and why she believes it is a good option for many women.  

In an exclusive interview with TheRightDoctors on Emcure AICOG tv, Dr. Nimish Shelat, consultant at Newberg IVF, Gujarat Institute of reproductive Medicine, spoke on the topic of oocyte donation. This is what he said: ' Oocyte donation is a very very important topic. Ideal donors are those which are almost 21 years of age. They should not have any kind of disease particularly genetic disorder because genetic disorder then can be carried forward. College girls who want who make money they just step in our clinics, but we do not accept them because they are under lot of stress of studies at the same time we do not want that they do something later they will regret. It is very important to keep all the details of the donor because this is a very very important record you may be able to trace other issues later on. You should have complete profile including height, weight, health, respiratory and cardiovascular system assessment. She should not carry HIV infection. The parents who will later on the recipient parents who will be having the baby, may have a baby which carries a blood group of the donor also. So both have to be counseled.'

How catastrophes help oocytes avoid disaster During meiosis, oocytes must attach homologous chromosomes to opposite spindle poles, but the cells take several hours to assemble a bipolar spindle. Gluszek et al. reveal that, in Drosophila oocytes, the microtubule catastrophe–promoting protein Sentin delays the formation of stable kinetochore–microtubule attachments until spindle assembly is complete, thereby preventing homologous chromosomes from incorrectly attaching to the same spindle pole. This biosights episode presents the paper by Głuszek et al. from the December 21st, 2015, issue of The Journal of Cell Biology and includes an interview with the paper's senior author, Hiroyuki Ohkura (University of Edinburgh, Edinburgh, Scotland, UK).

One of the most critical periods in mammalian development is early embryogenesis. Its timing and morphology have been well studied, but molecular processes are still poorly understood. Several transcriptomic studies have addressed these molecular events. However, development of early embryonic stages before activation of the embryonic genome depends on sufficiently stored products of the maternal genome and adequate de/activation and relocation of proteins. Therefore, this thesis addresses early mammalian development, i.e., oocyte maturation and the first steps of embryogenesis, by holistic iTRAQ-based discovery approaches and by a targeted approach based on SRM. Numerous proteins important for oocyte maturation and embryogenesis so far not described in the mammalian system were identified and quantified, and protein profiles for key players previously described in the literature were contributed. In oocyte maturation, bioinformatics analysis revealed proteins increasing in abundance involved in rearrangement of the cytoskeleton, protein transport and cell cycle progression. Supplementation of oocyte maturation media with the gonadotropins follicle stimulation hormone and luteinizing hormone resulted in an increase of developmentally important proteins, but did not change developmental rates. Addition of growth hormone during oocyte maturation led to diverse and opposing effects at the level of proteins and also did not influence subsequent embryo development. During early embryogenesis, a considerable fraction of proteins continuously increased in abundance, despite a strongly attenuated rate of translation reported for this period. Bioinformatics analysis revealed particularly interesting proteins involved in the p53 pathway, lipid metabolism and mitosis. Activation of the unfolded protein response is demonstrated, which may be an indicator of the still lower success rates of in vitro versus in vivo embryo production. Relevant differences between transcript and protein abundance levels were detected, e.g., for WEE2, which highlights the importance of innovative proteomic tools and workflows to complement transcriptome data of early embryogenesis. iTRAQ results of early embryogenesis were successfully verified by targeted 5-plex SRM analysis. By principal component analysis, SRM quantifications comprising a panel of only five proteins were shown to discriminate between all four developmental stages analyzed. Using an expanded 27-plex SRM assay, proteins were quantified in nine developmentally interesting stages and absolute protein contents were established for nine proteins. SRM is a highly sensitive tool for detection of disturbances and disorders of embryonic development at the molecular level, thus complementing morphological analyses by high resolution microscopy.

In the in vitro production of embryos in humans and animals it is aimed to produce embryos of good quality in order to reach a high pregnancy rate after the transfer on a recipient. Nevertheless, data until 2007 show that in Europe the pregnancy rate after the transfer of human IVF embryos was only 33% (de Mouzon et al., 2012). Recently time-lapse imaging of early embryonic cleavage was found to be a helpful and non-invasive tool to predict the developmental capacity of embryos and select embryos of good quality (Wong et al., 2010, Sugimura et al., 2012). As the morphokinetic parameters of the first and second cleavage were the most predictive values, the fate of an embryo seems to be, at least partly, already determined very early in embryogenesis. This determination of the developmental competence might even go back further namely until oocyte maturation. In this experiment we used bovine embryos as an animal model to study the reasons for success and failure of mitotic cleavage during early embryo development. First a live monitoring system for the observation of bovine embryos was applied in order to search for the values that are highly predictable for the developmental competence to the blastocyst stage. To consider the effect of the oocyte maturation onto the further development, we observed embryos from oocytes after in vitro (n=398) versus in vivo maturation (n=143). In average embryos that developed to the blastocyst stage showed an earlier timing of the first, second and third cleavage than embryos that arrested (p

Ein bislang nur wenig verstandenes chemo¬sensorisches Zellsystem stellen Spermien dar, die im weib¬lichen Genital¬trakt komplexe Gemische ganz verschiedener Liganden wahr-nehmen müssen, um ihre für eine erfolgreiche Befruchtung essentiellen Aufgaben erfüllen zu können. Dazu gehören u. a. ein sekundärer Reifungsprozess (Kapazitierung), die Weg¬findung zur Eizelle im Eileiter und die Akrosom¬reaktion zur enzymatischen Auflösung der Glyko¬protein¬matrix (Zona pellucida) der Oocyte. Die Sensor¬moleküle auf der Oberfläche des Spermiums, die eine Erkennung bestehender Konzentrations-gradienten von Amino¬säuren, Kohlen¬hydraten, Hormonen, von verschiedensten Ionen und Protonen im luminalen Milieu des weiblichen Genital¬trakts sowie der Kohlenhydrat-reichen Zona pellucida ermöglichen, sind jedoch trotz ihrer Bedeutung für eine erfolgreiche Fertilisation weitgehend unbekannt. Geschmacks¬rezeptoren repräsentieren spezialisierte Erkennungs¬moleküle, die in Sinnes-zellen der Zunge die präzise Detektion eines breiten Spektrums chemisch sehr diverser Geschmacks¬stoffe ermöglichen, welche auffällige Ähnlichkeiten mit den potentiellen Liganden in der wässrigen Umgebung von Spermien im weiblichen Genital¬trakt aufweisen. Interessanterweise werden diese Rezeptorproteine aber nicht nur in Geschmacks¬sinneszellen, sondern auch in chemosensorischen Zellen einer Vielzahl extra-oraler Gewebe exprimiert. In der vorliegenden Arbeit wurde deshalb mit Hilfe biochemischer, molekular- und zell-biologischer Techniken sowie mit reproduktions¬biologischen Methoden und unter Verwendung Geschmacks¬rezeptor-defizienter Mäuse der Frage nachgegangen, ob Rezeptor¬moleküle des Geschmacks¬systems als Kandidaten für chemische Sensor-moleküle von Spermien in Betracht kommen. Dabei wurde ein Detektions¬molekül für saure Geschmacksstoffe, der PKD2L1, immun-cyto¬chemisch im Hoden der Maus und in reifen murinen Spermien nach¬gewiesen. Funktionell könnte dieser im Flagellum von Spermien exprimierte Ionenkanal an der Registrierung der verschiedenen Protonen¬konzentrationen im Milieu des weib¬lichen Genital¬trakts beteiligt sein. Weiterhin konnte eine Expression von gustatorischen GPCRs der Tas1r-Familie (süß/umami) und Tas2r-Familie (bitter), in männ¬lichen Reproduktions¬organen und in reifen Spermien gezeigt werden. Zudem wurden Hinweise auf die Expression der gustatorischen G Protein α Untereinheit Gustducin, die in Geschmacks¬sinnes¬zellen an der Signal¬transduktion dieser beiden Rezeptor¬familien beteiligt ist, im männlichen Reproduktions¬system erbracht. Im Einzelnen konnten mit der RT-PCR-Technik Transkripte von 28 der insgesamt 35 Mitglieder der großen Familie der murinen Bitter¬rezeptoren (Tas2rs) aus Hoden-gewebe amplifiziert werden. Die Bedeutung der Expression von Bitter¬rezeptoren für die Reproduktion wurde exemplarisch anhand einer Gen-defizienten Maus für den Tas2r131 unter¬sucht. Bei dieser Knockin-Maus¬linie war die kodierende Rezeptor¬sequenz durch eine GFP-Expressions¬kassette ersetzt worden, so dass das Maus¬modell gleich-zeitig auch eine Bestätigung der Expression des Tas2r131 in späten Keim¬zell¬stadien der Spermato¬genese ermöglichte. Bei der Fertilitätsanalyse Tas2r131-defizienter Tiere waren unter Labor-Zucht¬bedingungen keine Veränderungen in der Anzahl der Nach¬kommen pro Wurf oder der Zeitspanne zwischen den Würfen feststellbar. Allerdings wiesen Tas2r131-defiziente Männ¬chen signifikant mehr epididymale Spermien auf als Wildtyp-Tiere. Darüber hinaus war bei Verpaarungs¬studien mit hetero¬zygoten Männchen eine Genotyp-Verschiebung zugunsten des Tas2r131 [-] Allels zu registrieren. Dieser Phänotyp könnte darauf hindeuten, dass der Tas2r131 eine funktionelle Rolle bei Tas2r-abhängigen Auswahlprozessen verschiedener Spermien¬populationen spielt, bei denen sich z. B. durch eine Regulation der Apoptose im Verlauf der Keimzell¬bildung (Spermatogenese) oder auch durch eine Beeinflussung z. B. der Weg¬findung im weiblichen Genitaltrakt ein Selektions¬vorteil für Tas2r131-defiziente Spermien ergeben könnte. Aus der Familie der Tas1-Rezeptoren, deren drei Mitglieder als Heterodimere für die Erkennung von süßen Stimuli und dem Geschmack von Mononatrium¬glutamat („umami“) verant¬wort¬lich sind, konnten in RT-PCR-Experimenten die beiden Unter-einheiten des Umami-Rezeptors, der Tas1r1 und Tas1r3, aus Hodengewebe der Maus amplifiziert werden. Mit Hilfe Subtyp- und Spezies-spezifischer Antikörper konnte gezeigt werden, dass beide Rezeptor¬proteine im Akrosom und in distinkten Abschnitten des Flagellums von murinen und humanen Spermien exprimiert werden. Die funktionelle Rolle des Umami-Rezeptors wurde mit Hilfe einer Tas1r1-defizienten mCherry Reportermauslinie unter¬sucht, die unter optimalen Zuchtbedingungen ebenfalls keine Fertilitäts¬einschränkungen erkennen ließ. Im Hoden dieser Tas1r1-defizienten Tiere waren jedoch morpho¬logische Veränderungen des Keim¬epithels und eine signifikant erhöhte Apoptose¬rate zu registrieren, die allerdings keine verminderte Anzahl reifer Spermien oder Störungen der Morphologie oder Motilität dieser Zellen zur Folge hatte. Stimulierungsexperimente mit isolierter Zona pellucida, dem physiologischen Auslöser der Akrosomreaktion, haben zudem gezeigt, dass keine Ein¬schränkungen bei Spermien Tas1r1-defizienter Tiere fest¬zustellen waren. Allerdings wiesen Tas1r1-defiziente Spermien eine signifikant höhere Rate an spontaner Akrosom¬reaktion auf, die in unkapazitierten Zellen mit signifikant erhöhten basalen Konzentrationen der second messenger cAMP und Ca2+ einherging. Durch eine Reduzierung der intra¬zellulären Konzentrationen dieser Botenstoffe, die elementare Aufgaben des Spermiums im Verlauf des sequentiellen Prozesses der Fertilisation regulieren, könnten Tas1-Rezeptoren somit durch eine basale Rezeptor-aktivität oder durch eine Liganden-induzierte Rezeptor¬stimulation sicherstellen, dass Spermien im weiblichen Genitaltrakt in einem Ruhezustand erhalten werden, bevor sie in Kontakt mit der Eizelle kommen können. Insgesamt kann dieser Nachweis einer funktionellen Expression von Geschmacks-rezeptoren in Spermien zu einem besseren Verständnis der Regulations¬mechanismen zentraler Spermien¬funktionen beitragen und langfristig möglicherweise auch repro-duktions¬medizinische Perspektiven zur gezielten positiven bzw. negativen Manipulation von Spermien und damit zur Behandlung männlicher Infertilität bzw. zur Entwicklung nicht-hormoneller Verhütungsmittel für den Mann eröffnen.

Several mRNAs are specifically transported to the anterior and posterior regions of Drosophila oocytes by microtubule-based motor proteins, but the organization of microtubules in these cells is unclear. Parton et al.  reveal that oocyte microtubules are highly dynamic and display a PAR-1-dependent bias in polarity that facilitates transport of oskar mRNA to the oocyte posterior. This biosights episode presents the paper by Parton et al. from the July 11, 2011, issue of The Journal of Cell Biology, and includes an interview with authors Richard Parton and Ilan Davis (University of Oxford, UK).

Similarities between the bovine female and women in terms of reproduction and fertility, such as oogenesis, folliculogenesis and reduced fertility with advanced age make the bovine a valuable model for the study of ovarian function and dysfunction as well as reproductive aging in women. The aim of the present work was to investigate the influence of donor age on follicle numbers, yield and quality of COCs obtained by repeated OPU and on the developmental competence in vitro after oocyte maturation in vitro versus in vivo. Further, the ability of oocytes from different age classes to reprogram nuclei of bovine fetal fibroblasts was studied. Since the individual is a major factor influencing parameters of fertility and results of ART in both humans and cattle, the present study used in parts the same animals to rule out inter-individual effects on the response to one or the other approach. Experiment 1 investigated the effect of donor age in non-superstimulated German Simmental heifers (n = 12, 14 months at the beginning of the experiments), young cows in their first lactation (n = 8, 2-4 years) and old cows (n = 8, 10-15 years). A total of 38 OPU sessions were performed in two experimental periods on independent sets of animals from all age classes: 5/5/5 (32 sessions) and 7/3/3 (6 sessions).
