Today, we're diving into an exciting peptide therapy called tesamorelin. You might have heard of it if you're interested in anti-aging treatments.  In this episode, we'll break down exactly what tesamorelin is, how it works in the body, and the potential benefits it can offer. Plus, we'll talk about the possible side effects and risks associated with the therapy, and how it compares to another popular peptide we discussed last week, sermorelin.  What is Tesamorelin? Tesamorelin is a synthetic peptide that acts as a growth hormone-releasing hormone (GHRH) analog. In simple terms, it stimulates the body's natural production of growth hormone (GH) by targeting the pituitary gland, which is responsible for releasing growth hormone.  Unlike direct growth hormone replacement therapy, where you inject synthetic growth hormone into your body, tesamorelin works by prompting your body to produce its own growth hormone naturally. This is often considered a more natural approach to restoring optimal hormone levels. Originally, tesamorelin was approved by the FDA to treat lipodystrophy (abnormal fat distribution) in HIV patients who were experiencing excess abdominal fat. However, its use has since expanded in the realm of anti-aging and fat loss due to its ability to promote fat metabolism, muscle development, and overall vitality. How Does Tesamorelin Work? In essence, tesamorelin taps into your body's natural ability to produce growth hormone, rather than injecting it directly. This is why it's often considered a safer, less invasive alternative to traditional growth hormone therapy. It's typically given once daily via subcutaneous injections (just under the skin). Depending on the health condition being treated, some individuals may need to dose less frequently. What's the Difference Between Tesamorelin and Sermorelin? While both tesamorelin and sermorelin are peptides that stimulate the release of growth hormone, they differ in their structure and the specific ways they interact with the body. Tesamorelin is a modified version of GHRH that specifically targets the release of growth hormone from the pituitary gland. It's particularly effective in reducing abdominal fat (especially visceral fat) and improving body composition, which makes it popular for individuals seeking fat loss and anti-aging benefits. Sermorelin, on the other hand, is a shorter form of GHRH and has a more general effect on growth hormone secretion. While it also stimulates the pituitary to release growth hormone, it is often used in younger individuals or those seeking overall growth hormone balance and anti-aging benefits rather than specifically targeting fat loss. Potential Benefits of Tesamorelin Therapy Fat Loss and Body Composition: One of the most well-known benefits of tesamorelin is its ability to reduce abdominal fat and improve overall body composition. It is especially effective at targeting visceral fat, the fat stored around internal organs. This can be beneficial for those looking to lose stubborn belly fat, which is linked to several health issues like heart disease, diabetes, high blood pressure, and fatty liver disease. Improved Muscle Mass: Since growth hormone plays a key role in muscle development, tesamorelin can help increase lean muscle mass and improve muscle tone. It's especially helpful for older adults or people recovering from injuries who want to retain or regain muscle strength. Increased Energy Levels: Higher levels of growth hormone can result in improved energy, vitality, and endurance. Many patients report feeling more energized throughout the day, which can improve quality of life and overall activity levels. Better Skin and Hair Health: Tesamorelin's effects on collagen production can contribute to improved skin tone, elasticity, and texture. It may also benefit hair health, making it a popular option for individuals seeking anti-aging benefits beyond just fat loss and muscle gain. Improved Metabolism: Tesamorelin may enhance the body's metabolism, aiding in better fat burning and more efficient use of nutrients, which can be beneficial for weight management. Cognitive Function: Some studies suggest that tesamorelin may have cognitive benefits, including improved memory and mental clarity, likely due to the overall boost in growth hormone levels. Potential Side Effects and Risks As with any therapy, tesamorelin comes with potential side effects and risks. While side effects are generally mild and well-tolerated, they can include: Injection site reactions: Pain, redness, or swelling at the injection site. Headaches: Some people report mild to moderate headaches, especially when first starting the therapy. Joint pain or muscle aches: Increased growth hormone levels can sometimes lead to discomfort in muscles or joints. Fluid retention: Some individuals may notice mild swelling or bloating, particularly in the hands or feet. Long-term use of growth hormone-stimulating therapies like tesamorelin may increase the risk of carpal tunnel syndrome, joint issues, or diabetes in predisposed individuals.  Although rare, there is a concern that stimulating growth hormone production could accelerate the growth of existing cancers, so it's important to have a thorough health evaluation before starting therapy. As always, consulting with a healthcare provider before starting tesamorelin therapy is essential, especially if you have a history of cancer, pituitary gland disorders, or chronic health conditions.

Today, we're talking about sermorelin peptide therapy, an emerging peptide therapy option that's gaining attention for its potential benefits in anti-aging, muscle health, and overall vitality.  Whether you've heard about it before or are learning about it for the first time, this episode will break down exactly what sermorelin is, how it works, and why some people are turning to it for a boost in their health. Let's dive right in! What is Sermorelin? Sermorelin is a synthetic peptide that mimics the naturally occurring hormone growth hormone-releasing hormone (GHRH), which stimulates the pituitary gland to release growth hormone (GH). Growth hormone is important for various functions in the body, including growth during childhood, metabolism, muscle and bone health, and tissue repair. As we age, our natural production of growth hormone declines, which can contribute to symptoms like reduced muscle mass, increased body fat, lower energy levels, and other signs of aging. Sermorelin therapy is often used to boost the body's natural production of growth hormone, rather than injecting synthetic growth hormone directly. How Does Sermorelin Work? Unlike traditional growth hormone replacement therapies, where synthetic growth hormone is injected directly into the body, sermorelin therapy encourages your body to ramp up its own production of growth hormone. This is often seen as a more natural approach, with fewer potential risks associated with long-term synthetic growth hormone use. Typically, sermorelin is administered via subcutaneous injection (injected under the skin) given in the belly or upper thigh once a day or three to five times per week. The goal is to restore growth hormone levels to a more youthful range, improving overall health and well-being. Potential Benefits of Sermorelin Therapy So, what can sermorelin peptide therapy do for you? While results can vary, some of the potential benefits include: Improved Muscle Mass and Strength: Growth hormone plays a key role in muscle growth, and as sermorelin stimulates the pituitary to release more of it, many patients report an increase in muscle mass and strength over time. Fat Reduction: Sermorelin may help increase fat burning and promote lean muscle development, which can aid in weight loss and fat loss. Better Sleep Quality: Growth hormone is linked to deeper, more restful sleep. Many people undergoing sermorelin therapy notice an improvement in sleep patterns. Enhanced Energy Levels: With increased growth hormone production, some individuals experience a boost in energy, stamina, and overall vitality. Improved Skin Tone and Elasticity: Sermorelin may help stimulate the production of collagen, leading to firmer, more youthful-looking skin. Faster Recovery and Healing: Increased growth hormone levels can help with the repair of tissues and muscles, speeding up recovery from injuries or workouts. Better Mood and Mental Clarity: Some users report enhanced cognitive function, better mood, and a clearer mind, likely due to the overall improvement in physical health and hormone balance. Potential Side Effects and Risks As with any treatment, sermorelin peptide therapy comes with its own set of potential side effects and risks. Most people tolerate the therapy well, but some may experience mild side effects, such as: Injection site reactions: Redness, swelling, or irritation at the site of injection. Headaches: Some people report headaches, particularly when starting therapy. Flushing or dizziness: A warm, flushed feeling or dizziness may occur, though it's typically short-lived. Joint or muscle pain: Occasionally, users may experience discomfort in muscles or joints, especially in the early stages of therapy. Water retention: Some people might notice mild swelling or water retention. In rare cases, there can be more serious side effects, such as excessive growth hormone levels, which could lead to conditions like carpal tunnel syndrome, diabetes, and  joint enlargement. It's important to have regular check-ups with a healthcare provider to monitor any side effects and ensure the treatment is working as intended. Additionally, since sermorelin stimulates the body's natural production of growth hormone, it's important for individuals to be screened for underlying medical conditions such as pituitary gland issues or active cancer, as these could be aggravated by the therapy. If you're interested in exploring sermorelin therapy, talk to a healthcare professional who specializes in hormone replacement or peptide therapies to see if it's right for you.

Upon diagnosing acute myeloid leukemia (AML), the initial step involves assessing a patient's eligibility for intensive chemotherapy. The standard treatment protocol for newly diagnosed AML encompasses intensive chemotherapy to achieve complete remission, followed by post-remission therapy, which may include additional chemotherapy and/or stem cell transplantation. Complete response rates to this approach range from 60% to 85% in adults aged 60 or younger. While this approach has proven effective, the risk of relapse within three years of diagnosis remains a significant concern. Numerous factors contribute to the likelihood of relapse, including short duration of remission, genetic derangements, prior allogeneic transplantation, advanced age, and concomitant comorbidities. These negative prognostic factors underscore the need for continuous exploration of novel therapeutic agents, as relapse remains a formidable barrier to treatment success. In a new study, researchers Simonetta I. Gaumond, Rama Abdin, Joel Costoya, Andrew V. Schally (awarded the Nobel Prize in Physiology or Medicine in 1977), and Joaquin J. Jimenez from the University of Miami, Florida Atlantic University and Veterans Affairs Medical Center, Miami, investigated newly emerging therapies targeting drug resistance in AML.

BUFFALO, NY- April 10, 2024 – A new #researchpaper was #published in Oncotarget's Volume 15 on April 8, 2024, entitled, “Exploring the role of GHRH antagonist MIA-602 in overcoming Doxorubicin-resistance in acute myeloid leukemia.” Acute myeloid leukemia (AML) is characterized by the rapid proliferation of mutagenic hematopoietic progenitors in the bone marrow. Conventional therapies include chemotherapy and bone marrow stem cell transplantation; however, they are often associated with poor prognosis. Notably, growth hormone-releasing hormone (GHRH) receptor antagonist MIA-602 has been shown to impede the growth of various human cancer cell lines, including AML. In this new study, researchers Simonetta I. Gaumond, Rama Abdin, Joel Costoya, Andrew V. Schally, and Joaquin J. Jimenez from the University of Miami, Florida Atlantic University and Veterans Affairs Medical Center, Miami examined the impact of MIA-602 as monotherapy and in combination with Doxorubicin on three Doxorubicin-resistant AML cell lines, KG-1A, U-937, and K-562. “Given the role of GHRH in multiple cancer types, it is possible that GHRH antagonists may offer an alternative treatment approach for AML as well as drug-resistant AML, which may circumvent the side effects associated with standard chemotherapy.” The in vitro results revealed a significant reduction in cell viability for all treated wild-type cells. Doxorubicin-resistant clones were similarly susceptible to MIA-602 as the wild-type counterpart. Their in vivo experiment of xenografted nude mice with Doxorubicin-resistant K-562 revealed a reduction in tumor volume with MIA-602 treatment compared to control. “Our study demonstrates that these three AML cell lines, and their Doxorubicin-resistant clones, are susceptible to GHRH antagonist MIA-602.” DOI - https://doi.org/10.18632/oncotarget.28579 Correspondence to - Simonetta I.

Noradrenaline (norepinephrine) is a neurotransmitter and hormone that plays a role in the body's "fight or flight" response.  Acetylcholine is a neurotransmitter (“brain” +” across” + “to send”) that helps transmit signals in the brain and body. Its name comes from its chemical structure, an acetate group and a choline molecule.  Dopamine is a neurotransmitter that plays a role in motivation, reward, and movement. Its name comes from its chemical structure, a combination of two molecules called dihydroxyphenylalanine and dopamine. Adrenaline (epinephrine) is a hormone and neurotransmitter that helps the body respond to stress. Its name comes from its source, the adrenal glands.  Serotonin is a neurotransmitter that is involved in mood, appetite, and sleep. Its name comes from its chemical structure, a combination of sero- (meaning "serum") and -tonin (meaning "tonic" or "substance that modifies").  Corticotropin-releasing hormone (CRH) is a hormone that stimulates the release of cortisol, a stress hormone. The name comes from its function of stimulating the release of corticotropin, a hormone that stimulates the adrenal glands. Also, it gets its name from its role in stimulating the release of adrenocorticotropic hormone (ACTH) from the pituitary gland, which in turn stimulates the release of cortisol from the adrenal gland. Vasopressin is a hormone that regulates water balance in the body. Its name comes from its ability to constrict blood vessels (vasoconstriction) and increase blood pressure. Vasopressin, also known as antidiuretic hormone (ADH), is so named because it regulates water balance by causing the kidneys to reabsorb water. Thyrotropin-releasing hormone (TRH) is a hormone that stimulates the release of thyroid-stimulating hormone (TSH), which regulates the thyroid gland. Its name comes from its function of stimulating the release of thyrotropin.  Oxytocin is a hormone that is involved in social bonding, childbirth, and lactation. Its name comes from its ability to stimulate uterine contractions (oxytocic) and milk ejection (lactogenic).  Gonadotropin-releasing hormone (GnRH) is a hormone that stimulates the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which regulate the reproductive system.

Heart failure with preserved ejection fraction (HFpEF) is, in many ways, a fascinating tale of modern cardiovascular medicine that, according to lead author Dr. Joshua Hare (University of Miami Miller School of Medicine), has taught cardiovascular researchers and clinicians a lot of humility. Understanding HFpEF in a variety of animal models has led to a paradigm shift away from heart failure linked to low ejection fraction. In this episode Associate Editor Dr. Jonathan Kirk (Loyola University Chicago Stritch School of Medicine) interviews Dr. Hare along with expert Dr. Julie McMullen (Baker Heart and Diabetes Institute, Melbourne, Australia) about the latest study by Kanashiro-Takeuchi et al. The Hare Lab was originally attracted to a cardiometabolic model of HFpEF pioneered by Dr. Joseph Hill, because in a large proportion of human patients, HFpEF is due to metabolic syndrome, which is a combination of obesity, diabetes, and hypertension. Armed with the ability to create this cardiometabolic HFpEF model, Hare and co-authors decided to test growth hormone-releasing hormone-agonist using a powerhouse of methods to determine if exercise intolerance could be improved. Kanashiro-Takeuchi et al. found that diastolic function and exercise performance improved, and myocyte hypertrophy and fibrosis were restored. Essentially all of the features of cardiometabolic HFpEF responded to treatment with GHRH-agonist. The authors did not see a reduction in blood pressure or weight, indicating a direct myocardial effect. In a wide-ranging discussion that touches on skeletal muscle, aging, sarcomeric proteins, and the technical complexities of running titin gels and PV loops, our experts explain why HFpEF is such a challenging syndrome to treat and why this translational research is so important.

The Peptide Podcast

Today we are talking about CJC 1295 and its potential benefits. All this and more in less than 2 minutes.  An excellent example of the ability peptides have to work together with our own bodies comes from a few of the most commonly used peptides available for anti-aging: growth hormone-releasing hormones (or GHRHs) and growth hormone-releasing peptides (GHRPs).  As you know, aging is essentially our bodies breaking down at the cellular level. As we age, we deal with things like decreased muscle mass, decreased immune function, a decreased sex drive, increased skin issues, change in mood, the list goes on and on.  All of this along with depression, and many more unwanted effects seem to inevitably come as part of the aging process. Some of this dysfunction can be treated with GHRH peptides like CJC-1295 or GHRP peptides like Ipamorelin or a combination of BOTH! Today we are going to focus on CJC 1295. What is CJC 1295? CJC 1295 is a lab-made peptide hormone, primarily functioning as a GHRH or amplifier. In simple terms, the peptide increases protein synthesis, human growth hormone (aka HGH) secretion, and insulin-like growth factor (or IGF-1).  IGF-1 is a hormone that's similar in molecular structure to insulin and plays an important role in childhood growth and has anabolic effects (or muscle-building effects) in adults.  What are the BENEFITS?  CJC 1295 is useful to those looking to increase lean muscle mass and strength by stimulating the release of growth hormone. It also promotes muscle recovery as it boosts protein synthesis levels and helps the growth of muscle tissues resulting in quicker recovery times for athletes and those with injuries. And because it stimulates the production of IGF-1, it can help decrease body fat and increase natural strength. Compared to other peptide therapies, CJC 1295 has a longer half-life of 30 minutes which requires fewer peptide injections and results in the continual release of growth hormone.  It also has minimal effect on cortisol levels. Cortisol is a hormone that's released into your bloodstream when your body undergoes stress. This hormone causes an increase in your heart rate and blood pressure. It's your natural “fight or flight” response. However, over time, if your body experiences repeated stress, you may begin to feel tired, irritable, depressed, and even experience weight gain.   BUT DOES IT WORK? Peptide therapies are not miracles in a bottle. They don't guarantee desired results. Like anything in life, you must also make lifestyle changes when it comes to certain desired outcomes. For example, a poor diet and lack of exercise can have a negative impact on your health and cause weight gain, joint pain, and can even lead to type 2 diabetes. Peptide therapy in addition to healthy lifestyle choices can help you achieve your health goals! Possible side effects include redness or itching at the injection site. You should tell your healthcare provider about any side effects you think you may be experiencing.  You can find more information at pepties.com.  That's peptides without the D.

However, GH activation of these GHR-expressing neurons is less studied. We have generated a novel GHR-driven Cre recombinase transgenic mouse line (GHR cre) in combination with the floxed tdTomato reporter mouse line we tracked and activated GHR-expressing neurons in different regions of the brain. We focused on neurons of the hypothalamic arcuate nucleus (ARC) where GHR was shown to elicit a negative feedback loop that regulates GH production. We found that ARC GHR+ neurons are co-localized with AgRP, GHRH, and somatostatin neurons, which were activated by GH stimulation. Using designer receptors exclusively activated by designer drugs (DREADDs) to control GHR-ARC neuronal activity, we revealed that activation of GHR-ARC neurons was sufficient in regulating distinct aspects of energy balance and glucose metabolism. Overall, our study provides a novel mouse model to study in vivo regulation and physiological function of GHR-expressing neurons in various brain regions. Furthermore, we identified for the first time specific neuronal population that responds to GH and directly linked it to metabolic responses in vivo. Copy rights belong to original authors.

See all the Healthcast at https://www.biobalancehealth.com/healthcast-blog/ The brain is complex and is not a static organ. It is always growing new cells and breaking down the old cells. Like the rest of the body the brain is in a state of flux all the time. As we age without our sex hormones and growth hormones, breaking down occurs more rapidly than regrowth and our brain literally shrinks Another quite rapid symptom is the loss of short -term memory at the time before menopause when testosterone and GH decrease to a critical level. These hormone losses trigger the diverting of the brain blood flow from the area of the brain that holds recent memories. This causes immediate loss of words you are looking for when trying to describe something or someone. Most people forget names of people and places. There is loss of special ability like the function you need to discern the length or size of something or interpret architectural plans. This immediate memory loss reverses in the first 6 months of testosterone replacement, if it is within the first 10 years after testosterone levels drop. “An Italian study in 2000 demonstrated that there is a cognitive impairment without dementia which increases with age and is more prevalent in women than men” “In the same year, Dr. Capurso and researchers at the university of Bari found an age -related decline in cognitive function that causes a mild deterioration in memory performance, executive functioning and speed of cognitive processing” “The study concludes that the aging associated cognitive decline may be preventable and suggest the following: Avoidance of cardiovascular and other chronic diseases Attaining a high -level education Maintenance of vision and hearing capacities. Dr. Maupin believes that brain function can be protected from decline by taking testosterone, estradiol (for women), keeping thyroid function and growth hormones optimal. Several studies reveal the truth that replacement of testosterone in the first 10 years after its decline, can delay the onset of Alzheimer's disease and dementia for 10 years after it would normally occur. Other studies on women showed that replacement of estradiol in any form delayed the onset of these diseases of aging brain by 10 more years if it is taken in the window of 10 years after menopause. This reveals how important the sex hormones are to our brains. We also want to talk about muscle mass, strength, and stamina and aging. The amount of muscle mass you maintain depends on how much testosterone and growth hormone you produce or replace, the amount and kind of exercise you do, the genetic composition of your muscle such as do you have 100% slow twitch muscle which gives you the ability for long distance and long lasting strenuous exercise, or 100% fast twitch muscle which makes you good at short spurts of muscle work, lifting weights, and short but powerful muscle work of any kind or were you born with a combo? Diet/Nutrition is also important because you can -not build muscle without the building blocks from animal protein. When you are given replacement hormone of testosterone, it stimulates your production of growth hormone which you make naturally. This is important because age related reduction in growth hormone is one of the most robust endocrine markers of biological aging. The reduction of GH and IGF-1 impairs reference memory and seems to be reversable with the administration of GHRH. (growth hormone releasing hormones). “muscle strength is a critical component of the ability to walk and to avoid falls and fractures. Reduced muscle strength as we age is a major cause for an increased prevalence of disability. If we can prevent the loss of muscle as we age, we will age more slowly and remain independent as we grow older. Advancing adult age is associated with profound changes in body composition, the principal component of which is a decrease in skeletal muscle This age-related loss of skeletal muscle is referred to as sarcopenia.” “Studies indicate that age related decline in skeletal muscle may contribute to such age associated changes as reduction in bone density, insulin sensitivity, and aerobic capacity.” The final component of this week's conversation references the sensory system. The principal conclusion of the discussion regarding the loss of sense of taste and smell, hearing and sight, suggests that attending to: Nutrition Hormones Lifestyle May expand your lifespan, while, at the same time, enhance the quality of that human life.

Ghrelin ist der natürliche Ligand des wachstumshormon-sekretagogen (GHS)-Rezeptors (Kojima, 1999). Es stimuliert die Wachstumshormon (GH)-Ausschüttung an der Hypophyse und wirkt appetitsteigernd. Bisherige schlafendokrinologische Untersuchungen zeigen, dass die Hormone wachstumshormon-freisetzendes-Hormon (GHRH), Somatostatin, corticotropin-freisetzendes Hormon (CRH) und Cortisol in die Schlafregulation involviert sind. Auch synthetische Wachstumshormon-Sekretagoge (GHS) modulieren beim Menschen den Schlaf und beeinflussen die nächtliche hormonellen Sekretion. Ziel dieser Arbeit war es, die Effekte von Ghrelin auf das Schlaf-EEG und die nächtliche Hormonsekretion von GH, ACTH, Cortisol, Prolaktin und Leptin bei jungen gesunden Männern zu untersuchen. Nach Gabe von 4 x 50 µg Ghrelin iv. zu Beginn der Nacht fand sich ein signifikanter Anstieg des Tiefschlafs im Schlaf-EEG und der assoziierten nächtlichen GH-, Cortisol- und Prolaktin-Sekretion. Die Leptinspiegel waren nicht signifikant verändert. Diese Arbeit konnte zeigen, dass exogen appliziertes Ghrelin signifikante Wirkungen auf den humanen Schlaf und die schlafassoziierte Hormonsekretion ausübt. Anhand der Ergebnisse ist davon auszugehen, dass Ghrelin nicht nur auf die GH-Sekretion, das Appetitverhalten oder das Gewicht Einfluss nehmen kann, sondern eigene endogen-schlafmodulierende Effekte ausübt und bei jungen gesunden Männern als tiefschlaffördernder Faktor angesehen werden kann. Weiterhin bewirkt Ghrelin einen deutlichen Effekt auf die somatotrophe und corticotrophe Hormonsekretion, indem es die physiologischen Sekretionsmuster von GH und Cortisol stimuliert und intensiviert. Bei Betrachtung der gegensätzlichen Wirkungen der einzelnen Hormone GHRH und CRH auf den Schlaf ist dabei bemerkenswert, dass Ghrelin die GH-sekretagogen und tiefschlaffördernden Effekte von GHRH und die Cortisol-sekretagogen Effekte von CRH vereint. Man kann postulieren, dass Ghrelin eine mögliche Schnittstelle des somatotrophen und des corticotrophen Systems darstellt.

Repeated injection of GHRH leads to a decrease in the GH response in normal subjects. Arginine (Arg) stimulates GH secretion by suppression of hypothalamic somatostatin. To confirm these findings, eight normal men were examined in a series of five settings: test 1 (GHRH/GHRH-TRH), 100 micrograms GHRH injected iv, followed by 100 micrograms GHRH, iv, after 120 min and 200 micrograms TRH, iv, after 150 min; test 2 (GHRH/Arg-TRH), like test 1, but instead of the second GHRH injection, a 30 g Arg infusion over 30 min; test 3 (GHRH/GHRH-Arg-TRH), like test 1, but additionally a 30 g Arg infusion after 120 min; test 4 (GHRH-Arg-TRH), iv GHRH and Arg infusion initially, followed by iv TRH after 30 min; and test 5 (TRH), 200 micrograms TRH, iv, at 0 min. For statistical evaluation, the area under the GH curve (AUC) from 0-120 min was compared with the AUC from 120-240 min. The GH response to the second administration of GHRH was significantly lower (P < 0.02) than the first increase [AUC, 0.5 +/- 0.01 min.mg/L (mean +/- SE) vs. 1.2 +/- 0.3]. No significant differences were found between the GH responses to either GHRH or Arg alone (AUC, 0.9 +/- 0.2 min.mg/L vs. 0.9 +/- 0.2). A larger GH increase (P < 0.02) was seen after GHRH-Arg compared to GHRH alone (AUC, 1.9 +/- 0.4 min.mg/L vs. 1.2 +/- 0.3). The GH response (P < 0.02) to GHRH-Arg stimulation was lower after previous GHRH injection than after GHRH-Arg stimulation alone (AUC, 1.9 +/- 0.4 min.mg/L vs. 3.5 +/- 0.9). There was a statistically significant difference between the TRH-stimulated TSH response in test 4 compared to that in test 5. We could show that decreasing GH responses to repeated GHRH can be avoided by a combined stimulation with GHRH/Arg. These findings suggest that the decreased GH response to a second GHRH bolus may be partly due to an elevated hypothalamic somatostatin secretion, which can be suppressed by Arg. The lower GH response to GHRH-Arg stimulation after a previous GHRH bolus suggests, furthermore, that the readily available GH pool in the human pituitary may be limited.

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide.

The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism. To determine the effect of GHRP on human somatotroph cells in vitro, we stimulated cell cultures derived from 12 different human somatotroph adenomas with GHRP alone and in combination with GH-releasing hormone (GHRH), TRH, and the somatostatin analog octreotide. GH secretion of all 12 adenoma cultures could be stimulated with GHRP, whereas GHRH was active only in 6 adenoma cultures. In GHRH-responsive cell cultures, simultaneous application of GHRH and GHRP had an additive effect on GH secretion. TRH stimulated GH release in 4 of 7 adenoma cultures; in TRH-responsive cell cultures there was also an additive effect of GHRP and TRH on GH secretion. In 5 of 9 adenoma cultures investigated, octreotide inhibited basal GH secretion. In these cell cultures, GHRP-induced GH release was suppressed by octreotide. In 5 of 5 cases, the protein kinase-C inhibitor phloretin partly inhibited GHRP-stimulated GH release, but not basal GH secretion. In summary, GH secretion was stimulated by GHRP in all somatotroph adenomas investigated, indicating that its unknown receptor and signaling pathway are expressed more consistently in somatotroph adenoma cells than those for GHRH, TRH, and somatostatin. Our data give further evidence that GHRP-stimulated GH secretion is mediated by a receptor different from that for GHRH or TRH, respectively, and that protein kinase-C is involved in the signal transduction pathway. Because human somatotroph adenoma cell cultures respond differently to various neuropeptides (GHRH, TRH, somatostatin, and others), they provide a model for further investigation of the mechanism of action of GHRP-induced GH secretion.
