HIV research is one of the clearest examples of molecular biology in action. In this Mol Bio Minutes episode, Dr. Ryan Jeep walks through how fundamental molecular techniques power everything from detection to drug resistance studies to cure-focused research. Ryan begins with HIV biology and detection, explaining how qRT-PCR enables highly sensitive viral load measurement. These assays not only detection strategies but also support research to monitor treatment efficacy and viral rebound. From there, he moves into drug resistance, describing how sequencing, RT-PCR, and cloning strategies help researchers map resistance-associated mutations. By generating recombinant reporter viruses and measuring infectivity against different drugs, scientists can better understand treatment failure and move toward more personalized therapeutic strategies. Finally, Ryan explores cutting-edge cure research, including CRISPR-Cas9 approaches aimed at either disabling integrated viral genomes or engineering HIV-resistant immune cells. Across all three areas one theme remains constant: PCR, sequencing, and cloning form the technological backbone of HIV research. As these tools continue to evolve, so too does the potential to improve outcomes and one day eliminate the virus entirely. Since recording this episode, Ryan has joined KBI Biopharma as a Scientist l in their Formulation Development Group.

After a life-changing accident, Vanessa spent years fighting a dangerous infection that kept coming back. Eventually, doctors discovered why: the bacteria fueling it were resistant to antibiotics. Her story leads us far beyond the hospital, into waterways, soils, and a hidden world where the medicines meant to save us may be helping create the next superbugs.
"Our goal of precision oncology has been to shift to tailored therapies that can help to improve treatment efficacy and ultimately improve patient outcomes. Resistance biomarker testing can help the care team to detect these genomic changes that the tumor may have acquired during therapy that makes the cells resistant to therapy. This information can be extremely helpful when we're talking about making choices about second-line or subsequent-line therapy," ONS member Danielle Fournier, DNP, APRN, AGPCNP-BC, AOCNP®, advanced practice RN at the University of Texas MD Anderson Cancer Center in Houston, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about drug resistance biomarker testing.

Highlights From This Episode "We know that biomarkers are playing an ever more important role in cancer care, and really, their use can range anywhere from helping us to confirm a given diagnosis, understand a patient's cancer susceptibility or risk, evaluate prognosis, as well as personalize treatment recommendations. … But in some cases, though, biomarkers can also help us to avoid therapies that are not likely to work. We also call these drug resistance biomarkers. These are those biomarkers that signify that a tumor is unlikely to respond to a given therapy." TS 1:50 "Resistance to cancer therapies is one of the most common issues that arises during cancer treatment. Because the populations of cancer cells within a tumor can be very diverse, when a given drug kills the cells that are sensitive to that therapy, it can also eventually leave behind resistant tumor cells, which can grow and multiply over time. So this can ultimately lead to a point where the treatment that was initially effective is no longer able to control the disease." TS 4:33 "While costs have come down, there can still be a cost associated with biomarker testing, and in some cases, this can be considered a barrier to care. What patients pay out of pocket can vary widely depending on their insurance coverage. So we have some data that was published from the American Cancer Society Cancer Action Network, and this was published a few years ago in 2023, which showed the average allowed unit cost to insurers per biomarker test ranged anywhere from about $79 for patients who were on Medicaid to about $224 for large-group, self-insured patients." TS 10:03 "There's research underway that's looking not only at genomic changes—so DNA changes that impact drug resistance—but how other substances such as RNA and proteins within the cell can also contribute to drug resistance. And this kind of falls into not just genomics but multiomics field. I have no doubt whatsoever that the use of artificial intelligence and machine learning is likely going to play a large role in drug resistance research. And really, these tools can help researchers to analyze complex data sets, identify novel resistance biomarkers, predict resistance patterns, as well as help to develop treatments that may overcome some of those resistance mechanisms."

Send a textImagine this scene:A family's house was destroyed when it was bombed during a war. They got out with the clothes on their backs – nothing more. When they were fleeing, the mother was hit with fragments from another bomb. It tore off part of her leg. Dirt got in the wound.They made it to a refugee camp, but the wound got infected. With nothing available to treat the injury, the infection got worse. She had a drug-resistant infection that wasn't treatable with regular antibiotics. Her entire leg and part of her hip had to be removed to save her life. She will have a physical disability for the rest of her life.This is just one story of drug resistance or antimicrobial resistance (AMR) and the impact of armed conflict. Report after report finds that victims of armed conflict and refugees – both those seeking shelter abroad and inside their own countries – are especially likely to suffer from drug-resistant infections.Dr. Aula Abbara, Consultant in Infectious Diseases and Acute Medicine and Honorary Senior Clinical Lecturer at Imperial College, London, has been studying the problem firsthand.She's worked with teams that found people injured in Syria's 15-year-long conflict not only suffered terrible wounds, but then developed worse infections because of crowded and unsanitary conditions in healthcare facilities. These war-damaged hospital laboratories in Syria, especially, lacked the capacity to test for drug-resistant bacteria, and so doctors didn't know which antibiotics to prescribe to treat patients' infections.Solutions require taking a One Health approach, Dr. Abbara and colleagues have found.She and her colleagues call for programs to bring in more health professionals and healthcare access; introduction of easy-to-use diagnostics so people's infections can be immediately diagnosed and thus treated with the correct drugs; stopping the improper use and distribution of antibiotics; and proper surveillance so that professionals know which drug-resistant infections are spreading and where.In this episode of One World, One Health, Dr. Abbara chats with host Maggie Fox about what she's seen and what might help.
Malaria exerts a devastating impact on communities in the Global South, with upwards of 600,000 deaths yearly, primarily young African children. Using genetic approaches, we have explored the molecular basis of Plasmodium falciparum antimalarial drug resistance, which poses a constant threat to malaria treatment and control efforts. Using a genetic cross, we earlier identified that mutations in PfCRT conferred parasite resistance to chloroquine, the former first-line antimalarial drug. Structural and functional studies reveal that these mutations enable this transporter of globin-derived peptides to efflux chloroquine away from its heme target in parasitized erythrocytes. We also identified novel PfCRT variants that mediate resistance to piperaquine, a first-line combination partner drug that recently failed across Southeast Asia. We and others have also shown that mutations in Kelch13 are causal for parasite resistance to artemisinin, the core component of all current combination therapies, and have identified their emergence in east Africa. Kelch13 mutations affect multiple intracellular processes including hemoglobin endocytosis and degradation, mitochondrial physiology, and artemisinin-induced cellular quiescence. In anticipation that artemisinin partial resistance will lead to this drug becoming ineffective at treating severe malaria, we also have also leveraged a genetic cross to explore parasite susceptibility to quinine, an alternative treatment for severe disease. This work has identified a novel drug-metabolite transporter, DMT1, as a novel determinant of quinine resistance. Our ongoing efforts to identify new therapeutic approaches to treating artemisinin-resistant malaria include developing parasite-specific proteasome inhibitors, which synergize with artemisinin and restore its activity including against resistant parasites. Insights gained into molecular resistance mechanisms and genetic markers are being incorporated into global efforts to mitigate the emergence and spread of multidrug-resistant malaria.
Drug resistance derails even the most advanced cancer treatments, but what if we could restore sensitivity to existing therapies instead of starting over? Neil Bhowmick, chief scientific officer at Kairos Pharma, joins In Vivo to discuss how his company is tackling resistance in oncology. We explore the company's lead asset, ENV-105, which is showing over 13 months of progression-free survival in Phase II prostate cancer trials by resensitizing tumors to hormone therapy, with significantly lower toxicity than standard alternatives like chemotherapy or radiopharmaceuticals. Bhowmick explains the complex biology behind different resistance mechanisms, shares early data on GITR-modulating therapies designed to expand T cell populations for immunotherapy, and discusses their approach to developing companion biomarkers for patient selection. We also dive into the clinical and commercial rationale for combination approaches and what milestones to watch in the coming year.

Scott A. Armstrong, M.D., Ph.D., of the Dana-Farber Cancer Institute, studies how certain aggressive forms of acute myeloid leukemia (AML) develop and survive. His work centers on a protein called menin, which helps leukemia cells keep cancer-promoting genes switched on. Armstrong's team has found that blocking menin with specially designed drugs can shut down these gene programs, push leukemia cells to mature, and slow or stop the disease in lab models and patients. While some leukemias adapt by developing mutations in menin or finding other ways to survive, his research is revealing why certain genes are especially dependent on menin and how to target them more effectively. These discoveries are now shaping new treatments, drug combinations, and potential strategies for other cancers that rely on similar mechanisms.

Armstrong's team has found that blocking menin with specially designed drugs can shut down these gene programs, push leukemia cells to mature, and slow or stop the disease in lab models and patients. While some leukemias adapt by developing mutations in menin or finding other ways to survive, his research is revealing why certain genes are especially dependent on menin and how to target them more effectively. These discoveries are now shaping new treatments, drug combinations, and potential strategies for other cancers that rely on similar mechanisms.

Send us a textDrug-resistant germs are hidden killers in more than one way. Not only are the microbes invisible to the human eye, in many places, they're invisible because people simply are not looking for them systematically.Doctors often do not know what infections their patients have and treat them based on best guesses, which allows for ineffective treatments and exacerbates drug resistance. Policymakers don't know which infections are most common among populations and cannot make informed decisions about needed treatments or vaccines.This is a major problem across Africa and a new report shows just how complex the problem is.The Mapping AMR and Antimicrobial use Partnership (MAAP), which included the One Health Trust as well as the African Society for Laboratory Medicine; Africa CDC; the East, Central, and Southern Africa Health Community; Innovative Support to Emergencies, Diseases, and Disasters, a nonprofit focused on technology and communication; the clinical research group IQVIA; and the West African Health Organization, collected data from laboratories from 14 countries in Africa (Burkina Faso, Cameroon, Gabon, Ghana, Kenya, Eswatini, Malawi, Nigeria, Senegal, Sierra Leone, Tanzania, Uganda, Zambia, and Zimbabwe). “The study revealed significant gaps in bacteriology testing capacities,” the group, whose work was paid for by the UK government's Fleming Fund, wrote in PLoS Medicine.It's the biggest survey yet of testing for antimicrobial resistance – AMR or drug resistance – in Africa.Among the gaps: too little testing overall, a lack of laboratory capacities, and poor coordination and analysis of records. Many records were kept only on paper, which made them almost impossible to access.None of this surprises Dr. Sabiha Essack, South African Research Chair in Antibiotic Resistance and One Health and Professor in Pharmaceutical Sciences at the University of KwaZulu-Natal. In an ideal world, she says, a doctor, nurse or other professional should see a patient, test them to see what specific microbe is causing an infection, check to see which drugs will successfully fight that germ, and then treat the patient accordingly.Cheap point-of-care tests should be available everywhere and the results of those tests should be entered into systems that officials can use to make policy decisions, she says. Listen as she tells One World, One Health host Maggie Fox other ways to improve our knowledge about the drug-resistant infections that lurk out there. Want to know more?

BUFFALO, NY - April 11, 2025 – A new research perspective was published in Oncotarget, Volume 16, on April 4, 2025, titled “GSK3β activation is a key driver of resistance to Raf inhibition in BRAF mutant melanoma cells." In this work, first author Diana Crisan and corresponding author Abhijit Basu from the University Hospital Ulm led a team that presents experimental evidence pointing to the protein GSK3β as a key contributor to drug resistance in melanoma. Their findings suggest that GSK3β becomes increasingly active in cancer cells during treatment, helping them survive and adapt despite ongoing therapy with BRAF inhibitors. Melanoma is a type of skin cancer in which nearly half of patients have mutations in the BRAF gene that accelerate tumor growth. While treatments targeting BRAF, known as BRAF inhibitors, initially work well, tumors often find ways to fight back. This research perspective explores how GSK3β, a protein involved in metabolism and cell survival, becomes more active in melanoma cells that develop resistance to BRAF inhibitors. Researchers treated melanoma cells with a common BRAF mutation using Dabrafenib, a widely used BRAF inhibitor. Over time, the cancer cells developed resistance and showed a marked increase in GSK3β levels. This pattern was confirmed across multiple melanoma cell models, suggesting that the finding is consistent and reliable. Importantly, the researchers observed that treating resistant cancer cells with a GSK3β inhibitor significantly reduced their growth. This result suggests that blocking this protein could restore sensitivity to treatment, highlighting GSK3β as a promising therapeutic target and supporting the idea of combining GSK3β inhibitors with existing melanoma therapies. “Remarkably, treatment of BRAFi-resistant melanoma cells with the GSK3 inhibitor LY2090314 for three weeks could overcome resistance and significantly decreased melanoma cell growth, confirming the causal role of GSK3 activation for BRAFi resistance development.” The research perspective adds to ongoing efforts to understand and overcome melanoma drug resistance. It shows that resistance is not driven only by genetic mutations but may also involve adaptive changes in the cell's internal signaling and survival mechanisms. By identifying GSK3β as a potential contributor, the authors offer a new direction for improving the durability of targeted treatments in melanoma. As research continues, GSK3β may be a critical factor in the long-term success of melanoma therapy, particularly for patients who have stopped responding to standard BRAF-targeted drugs.

BUFFALO, NY - February 6, 2025 – A new #casereport was #published in Volume 16 of Oncotarget on February 5, 2025, titled “Acquired RUFY1-RET rearrangement as a mechanism of resistance to lorlatinib in a patient with CD74-ROS1 rearranged non-small cell lung cancer: A case report." In this case report, Jenny L. Wu from Vanderbilt University School of Medicine and Wade T. Iams from Vanderbilt-Ingram Cancer Center describe a rare case of drug resistance in a patient with advanced non-small cell lung cancer (NSCLC). The patient, a 42-year-old man who had never smoked, initially responded well to lorlatinib, a targeted therapy designed to treat cancer driven by specific genetic alterations. However, after six months, his cancer began to grow again. Clinicians discovered that this was due to a new genetic change, known as the RUFY1-RET fusion. This finding highlights how cancers can adapt to treatment and the importance of ongoing genetic testing to guide therapy decisions. NSCLC is the most common type of lung cancer, and in some cases, it is driven by genetic changes that can be targeted with specific drugs. The patient's cancer originally had a ROS1 gene rearrangement, which made it responsive to lorlatinib. But as time went on, the cancer started to grow again, and tests revealed a new genetic alteration called RUFY1-RET fusion, which likely caused resistance to lorlatinib. This new genetic change was identified using RNA next-generation sequencing (RNA NGS), an advanced test that can find mutations that standard genetic tests might miss. After discovering the RUFY1-RET gene fusion, the patient was treated with a combination of lorlatinib and pralsetinib, a drug that specifically targets RET gene alterations. While this combination helped control the cancer for about four months, the patient's condition unfortunately worsened after four months. “This is the first reported case of a RET fusion as a potential mechanism of resistance to lorlatinib, it identifies a novel RET fusion partner, and it emphasizes the importance of testing for acquired resistance mutations with both DNA and RNA at the time of progression in patients with targetable oncogenic drivers.” Understanding cases like this can help clinicians and researchers develop more effective treatment strategies, including combination therapies that target multiple genetic changes to combat drug resistance. While the combined therapy in this case provided only temporary benefits, it offers important insights for future research and patient care, particularly for cancers that no longer respond to standard treatments.

Dr. Aileen Marty, Infectious Disease Specialist and Professor at Florida International University, joins Bob Sirott to talk about the latest health news. Dr. Marty discusses the development of an antibiotic that would make it difficult to develop a drug resistance and when we could see it at the doctor’s office.
The problem of antimicrobial resistance – AMR for short – is clear. More and more of these germs resistant to existing treatments are emerging everywhere, and there's little disagreement that governments, nonprofits, doctors, patients, and politicians all need to help tackle the problem.But people need to agree on what to do, and they need to agree on how to measure progress.That's where targets come in.Aislinn Cook, a senior research fellow in infectious disease epidemiology on the antimicrobial resistance team in the Centre for Neonatal and Pediatric Infection of St. George's University in London, is helping set some of those targets. Cook, who's also affiliated with the Health Economics Research Centre at the University of Oxford, has helped write a series of papers in the Lancet medical journal bringing attention to the problem of antimicrobial resistance. AMR is a big topic of international discussion in 2024, due in part to it being one of the topics of the United Nations High-Level Meeting, and the Lancet series was put together to help focus that discussion.Cook's paper proposes some clear targets to reach by 2030: a 10 percent reduction in mortality from drug-resistant infections; a 20 percent reduction in inappropriate human antibiotic use; and a 30 percent reduction in inappropriate animal antibiotic use.These goals should be achievable, Cook says. Listen as she tells One World, One Health about some concrete ways the world can work together to control the spread of drug-resistant germs.Learn more about the struggle to control drug-resistant bacteria, viruses, and fungi in some of our other episodes. We've spoken with experts about how vaccines can help prevent the spread of drug-resistant germs, about tracking superbugs in sewage, and the surprising rise of drug-resistant fungi. Experts in drug design have talked to us about the search for new and better antibiotics and how these little organisms are winning an arms race against us. Filmmakers have told us about how storytelling can help people understand the threat while global health specialists explained that good stewardship can keep the antibiotics we have working as they should.

It's not a worm, it's a fungus among us. Today's topic is ringworm. Joining me today is Regents Professor of Clinical Laboratory Science at Texas State University and author of an article published in The Conversation last year, but a topic still worth discussing. Ringworm fungal infections are common in the US and are becoming increasingly resistant to treatment
Drug-resistant infections are a problem for everyone, but especially for newborns. They don't have fully developed immune systems, and their bodies are less equipped to fight infections.The risk is highest for infants born sick or prematurely. Bloodborne infections – sepsis – are one major threat to newborns. Sepsis can move quickly, overpowering the body and causing severe illness and even death within hours. Doctors don't have time to test babies to see what's infecting them and have to treat them based on what Dr. Mike Sharland calls a best guess. These infections are often resistant to the drugs that are available to treat them, too. National and international guidelines can help doctors make difficult and life-altering decisions about treatment, but there's not much guidance for health professionals treating newborns. That's in part because there is so little research on which antibiotics work in newborns. Sharland, a pediatric infectious disease specialist at St George's University of London, is helping lead a group running the clinical trials needed to form the basis of guidelines.In this episode, Dr. Sharland tells us about the terrifying growth of drug-resistant infections in newborns and the need for better antibiotics for these vulnerable babies.
Brazil's Proactive Measures Against HIVBrazil has been at the forefront of combating HIV, implementing proactive measures that have made a significant difference. The country began providing no-cost access to CD4 and viral load testing and antiretroviral drugs as early as 1996. This early intervention and consistent approach led to a remarkable outcome: the number of HIV cases in Brazil was significantly lower than initially predicted. An article from the New England Journal of Medicine stated that initial estimates predicted Brazil would have 1.2 million people infected with HIV by the year 2000, but with the strategies the country put in place, their actual numbers were about half of what was predicted. By offering free access to treatments and diagnostic tests, Brazil showcased the importance of early and sustained intervention in managing and reducing the spread of HIV. The Rising Challenge of HIV Drug ResistanceOne of the most pressing challenges in the fight against HIV is the development of drug resistance. Dr. Ricardo Diaz emphasizes that as the HIV virus replicates, it can produce strains resistant to treatment. This resistance threatens the efficacy of antiretroviral drugs, making it crucial to monitor and manage. The World Health Organization reports an increasing rate of HIV drug resistance, underscoring the need for continuous research, monitoring, and adaptation of treatment strategies. Pre-exposure Prophylaxis (PrEP) Drugs Exist, but are not 100% EffectivePrEP, or pre-exposure prophylaxis, is also an antiretroviral drug given to uninfected individuals who are at risk of infection to reduce their chances of acquiring HIV. PrEP is highly effective at preventing HIV when taken as indicated, but much less effective when it isn't taken consistently. Additionally, it's possible to be exposed to HIV strains that are drug resistant while on PrEP, so monitoring resistance in people on PrEP is another important step in prevention. The Gap in HIV Drug Resistance TestingDespite the advancements in treatment, there's a noticeable disparity in HIV drug resistance testing, especially in Brazil. Dr. Diaz highlights that while a centralized lab in Brazil performs genotype testing, the number of tests conducted falls short of the actual need. With 10% of patients on treatment showing a viral load above the desired limit, the demand for resistance testing is evident. Bridging this gap and increasing surveillance efforts is essential to tailor treatments effectively and combat the spread of drug-resistant HIV strains.
Vaccines are lifesavers. Childhood vaccines save 4 million lives every year, according to the US Centers for Disease Control and Prevention. And it turns out vaccines don't just save lives by directly preventing disease. They can save lives by reducing the rise of drug-resistant pathogens (mostly bacteria and viruses). This is because people who are vaccinated are less likely to get sick and to get treated either appropriately or inappropriately with antibiotics and antiviral drugs. And less use of these valuable drugs means less opportunity for germs to develop resistance to them. The One Health Trust set out to quantify just how well vaccination could reduce the emergence and spread of antimicrobial resistance or drug-defying germs. The latest report from the One Health Trust pulls together a variety of studies showing the impact of vaccines not only on drug resistance but also on economies, especially in low- and middle-income countries. Some highlights: A typhoid vaccination campaign for infants could prevent more than 53 million cases of drug-resistant typhoid in low- and middle-income countries over 10 years. A successful rotavirus vaccination program in Africa and Asia could prevent more than 13 million cases of diarrhea that otherwise would be treated with antibiotics – reducing opportunities for bacteria to evolve resistance to those drugs. In Indonesia alone, vaccinating 50% of eligible people with pneumococcal vaccine over five years could save more than US$2 million in costs related to treatment failure. One Health Trust Fellow and Director of Partnerships, Dr. Erta Kalanxhi, led the team that put together the report. Listen as she chats with One World, One Health host Maggie Fox about how vaccines can prevent the rise of drug-resistant bacteria and viruses.
Drug-defying superbugs can be found in manure, soil, the ocean, and especially in sewers. These places are sources of infection, but they also provide a way to keep an eye on which drug-resistant germs are where – and how much they are changing. The World Health Organization encourages mapping all of the places drug-resistant organisms are popping up, and what kind of organisms there are. “If no action is taken, AMR (antimicrobial resistance) could cost the world's economy US$ 100 trillion by 2050,” WHO says. Windi Muziasari, PhD, became passionate about tracking these deadly germs while doing postdoctoral research at the University of Helsinki in Finland. The Indonesian-born scientist founded her own company to do this mapping for governments, communities, and companies. As Founder and CEO of ResistoMap, Muziasari has looked for drug-resistant microbes in agricultural runoff, in hospitals, under city streets, among wildlife, and elsewhere in dozens of countries. The hope is to act as an early warning system so that companies, governments, and others can do something about the problem. “Almost everywhere is polluted,” she tells us on the One World, One Health podcast. Listen as Windi Muziasari tells host Maggie Fox about how and why she got started and what she's learned since launching ResistoMap.

BUFFALO, NY- October 11, 2023 – A new research paper was published in Oncotarget's Volume 14 on October 4, 2023, entitled, “Inhibiting BRAF/EGFR/MEK suppresses cancer stemness and drug resistance of primary colorectal cancer cells.” Drug resistance is a major barrier against successful treatments of cancer patients. Gain of stemness under drug pressure is a major mechanism that renders treatments ineffective. Identifying approaches to target cancer stem cells (CSCs) is expected to improve treatment outcomes for patients. In their new study, researchers Astha Lamichhane, Gary D. Luker, Seema Agarwal, and Hossein Tavana from The University of Akron, University of Michigan and Georgetown University aimed to elucidate the role of cancer stemness in resistance of colorectal cancer cells to targeted therapies. “[...] we developed spheroid cultures of patient-derived BRAFmut and KRASmut tumor cells and studied resistance mechanisms to inhibition of MAPK pathway through phenotypic and gene and protein expression analysis.” They found that treatments enriched the expression of CSC markers CD166, ALDH1A3, CD133, and LGR5 and activated PI3K/Akt pathway in cancer cells. The team examined various combination treatments to block these activities and found that a triple combination against BRAF, EGFR, and MEK significantly reduced stemness and activities of oncogenic signaling pathways. This study demonstrates the feasibility of blocking stemness-mediated drug resistance and tumorigenic activities in colorectal cancer. “Our approach to identify mechanisms of drug resistance of patient-derived cancer cells to targeted therapies and develop effective treatments is promising toward cancer precision medicine.” DOI - https://doi.org/10.18632/oncotarget.28517 Correspondence to - Hossein Tavana - tavana@uakron.edu Sign up for free Altmetric alerts about this article - https://oncotarget.altmetric.com/details/email_updates?id=10.18632%2Foncotarget.28517 Subscribe for free publication alerts from Oncotarget - https://www.oncotarget.com/subscribe/ Keywords - cancer, drug resistance, cancer stem cells, patient-derived tumor model, colorectal cancer, combination treatment About Oncotarget Oncotarget (a primarily oncology-focused, peer-reviewed, open access journal) aims to maximize research impact through insightful peer-review; eliminate borders between specialties by linking different fields of oncology, cancer research and biomedical sciences; and foster application of basic and clinical science.
