MedicalResearch.com Interview with: [caption id="attachment_59179" align="alignleft" width="150"]Robert Wild, Ph.D Chief Scientific Officer Dracen Pharmaceuticals Dr. Wild[/caption] Robert Wild, Ph.D Chief Scientific Officer Dracen Pharmaceuticals   MedicalResearch.com:  What is the background for the development of sirpiglenastat, i.e., would you briefly explain what is meant by glutamine antagonist? Response: Cancer cells consume and use glutamine for both energy generation and as a source of carbon and nitrogen for biomass accumulation. Many oncogenes and tumor suppressor genes drive large-scale metabolic reprogramming of tumors into glutamine addiction. These highly proliferating tumors create a hostile and immunosuppressive tumor microenvironment (TME), which is nutrient- depleted, acidic and hypoxic in nature. Sirpiglenastat (DRP-104), is a novel broad-acting glutamine antagonist that inhibits all 10 known glutamine metabolism enzymes. DRP-104 was designed to preferentially inhibit glutamine metabolism in tumors and associated TME and not in normal tissues, providing a large therapeutic window. DRP-104 demonstrates powerful direct apoptotic (cell death) properties and immune modulatory mechanisms through broad remodeling of the TME to infer DRP-104 impacts immune-metabolism. Inhibition of glutamine metabolism leads to:
  • Induction of apoptosis in glutamine-addicted tumor cells leading to substantial single-agent activity and tumor regressions
  • Rebalance of the TME that enhances immune cell infiltration and function
  • Differentiation and modulation of adaptive and innate immune cells toward a highly proliferative, activated and long-lived phenotype for a long-term durable response.

MedicalResearch.com Interview with: [caption id="attachment_59163" align="alignleft" width="70"]Yujin Hoshida Dr. Hoshida[/caption] Yujin Hoshida, MD, PhD Director, Liver Tumor Translational Research Program CPRIT Scholar in Cancer Research Harold C. Simmons Comprehensive Cancer Center Professor of Internal Medicine Division of Digestive and Liver Diseases, Department of Internal Medicine University of Texas Southwestern Medical Center MedicalResearch.com:  What is the background for this study?  Response: Liver cancer is the fastest rising cause of cancer-related death in the U.S. with the sharply growing epidemic of obesity and non-alcoholic fatty liver disease. Late diagnosis at advanced stage is the main reason for the poor survival of liver cancer patients. Therefore, professional societies recommend semi-annual liver cancer screening for early diagnosis. However, it's practically infeasible due to the vast size of patient population (estimated to affect one-fourth of population). Thus, we urgently need tools to identify a small subset of patients with elevated liver cancer risk, on which we can concentrate our effort of screening.

MedicalResearch.com Interview with: [caption id="attachment_59166" align="alignleft" width="200"]Dr. Amy Kirkham, PhD Assistant Professor of Clinical Cardiovascular Health Faculty of Kinesiology & Physical Education University of Toronto Affiliate Scientist at Toronto Rehabilitation Institute Dr. Kirkham[/caption] Dr. Amy Kirkham, PhD Assistant Professor of Clinical Cardiovascular Health Faculty of Kinesiology & Physical Education University of Toronto Affiliate Scientist at Toronto Rehabilitation Institute MedicalResearch.com:  What is the background for this study?  Response: Women who have had a breast cancer diagnosis are at least two-fold and often higher risk of cardiovascular or heart disease compared to women without a history of breast cancer. Older age, higher body mass index, and receipt of chemotherapy treatment that can injure the heart are risk factors for cardiovascular death after a breast cancer diagnosis. Time-restricted eating is a type of intermittent fasting that appears to be easy to follow and to improve some measures of metabolic health but has not been studied in populations with a cancer history. Time-restricted eating simply involves consuming all calorie intake within a specific time window, commonly 8 hours, like between 12 and 8 pm, and then only consuming water or black coffee outside of those hours. We enrolled breast cancer survivors who were aged 60 or older, had an overweight or obese mass index, and were finished chemotherapy treatment in a single-arm trial of time-restricted eating for 8 weeks. We asked participants to restrict their calorie intake between 12 and 8 pm from Monday to Friday with no restrictions on weekend and no further instructions on what to eat.

Response: On May 2, Guardant Health announced the availability of Shield™, our first blood-based test for the detection of early-stage colorectal cancer (CRC). Colorectal cancer is the second-leading cause of cancer deaths in the U.S., so this announcement represents a tremendous public health opportunity. Here’s why: This new test will help people identify more CRC at its earliest stages, when it is most treatable. It offers an accurate, easy-to-complete, blood-based approach to CRC screening. It can be completed with a convenient blood draw during any healthcare provider visit.

MedicalResearch.com Interview with: [caption id="attachment_59128" align="alignleft" width="125"]Megan Clarke, Ph.D., M.H.S., Earl Stadtman Investigator Division of Cancer Epidemiology and Genetics National Cancer Institute Dr. Clarke[/caption] Megan Clarke, Ph.D., M.H.S., Earl Stadtman Investigator Division of Cancer Epidemiology and Genetics National Cancer Institute MedicalResearch.com:  What is the background for this study? 
  • Through our prior work, we have demonstrated that uterine cancer incidence rates have been significantly increasing in the U.S. from 2003 to 2015 and that these increases were primarily driven by rising rates of aggressive (non-endometrioid) subtypes of this cancer. We observed that rates of these aggressive cancers increased among all women and were more than twice as high among Non-Hispanic Black women compared to other racial and ethnic groups. Factors explaining these trends, as well as the disproportionately higher rates of these aggressive subtypes among non-Hispanic Black women, remain unclear, in part because risk factors are poorly understood.
  • In addition to differences in incidence rates by race and ethnicity, we have also observed strong disparities in our prior studies, with Non-Hispanic Black women having substantially lower 5-year survival, regardless of subtype or stage at diagnosis, compared to other racial and ethnic populations.
  • The next logical step, and the focus of the current study, was to evaluate how increases in the incidence of aggressive, non-endometrioid uterine cancer affects racial disparities and rates of death from uterine cancer.

MedicalResearch.com Interview with: [caption id="attachment_59092" align="alignleft" width="200"]Leticia Nogueira, PhD, MPH Senior Principal Scientist, Health Services Research American Cancer Society, Inc. Kennesaw, GA 30144 Dr. Nogueira[/caption] Leticia Nogueira, PhD, MPH Senior Principal Scientist, Health Services Research American Cancer Society, Inc. Kennesaw, GA 30144 MedicalResearch.com:  What is the background for this study?  Response: Proton Beam Therapy (PBT) can deliver higher dose of radiation to the tumor with less damage to surrounding healthy cells. Therefore, PBT is potentially superior to photon-based radiation therapy to treat tumors with complex anatomy, surrounded by sensitive tissues, or for treating childhood cancer (where long-term side effects of radiation therapy are a main concern). However, PBT can cost twice as much as photon-based radiation therapy.

MedicalResearch.com Interview with: [caption id="attachment_59088" align="alignleft" width="100"]Katie M. O’Brien PhD Chronic Disease Epidemiology Group National Institute of Environmental Health Sciences Dr. O'Brien[/caption] Katie M. O’Brien PhD Chronic Disease Epidemiology Group National Institute of Environmental Health Sciences MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Vitamin D may protect against breast cancer. Although women of color have lower average vitamin D levels than non-Hispanic White women, few studies have considered the role of race/ethnicity. In a sample of self-identified Black/African American and Hispanic/Latina women, we observed that vitamin D concentrations measured in blood were inversely associated with breast cancer, particularly among Latinas. These findings indicate that vitamin D may protect against breast cancer, including among racial/ethnic groups with low average circulating levels.
Author Interviews, Brigham & Women's - Harvard, Cancer Research, Genetic Research, Nature / 18.04.2022

MedicalResearch.com Interview with: [caption id="attachment_59041" align="alignleft" width="150"]Jason Vassy Dr. Vassy[/caption] Jason Vassy, MD, MPH Brigham and Women's Hospital Division of General Internal Medicine & Primary Care Brigham’s Precision Population Health at Ariadne Labs and VA Boston  MedicalResearch.com:  What is the background for this study?    Response: A person’s risk of developing diseases such as type 2 diabetes or breast cancer may be influenced by thousands of genetic differences, the effects of which can be combined to derive a single score, often called a polygenic risk score (PRS). PRS might be useful to help patients and their physicians make tailored decisions about their health care, but several challenges to the clinical implementation of PRS remain. Most importantly, most PRS are less accurate in individuals of non-European descent, since most genomic research to date has been conducted in European populations. Another key challenge is that physicians and patients will need support to understand polygenic risk score and use them to make medical decisions. Clinical guidelines do not yet exist to help a physician know whether and how they should treat a patient with a high-risk score differently than an average-risk patient. We designed the Genomic Medicine at VA (GenoVA) Study to address some of these challenges.
AACR, Author Interviews, Brigham & Women's - Harvard, Cancer Research / 18.04.2022

MedicalResearch.com Interview with: [caption id="attachment_59050" align="alignleft" width="150"]Ajit Johnson Nirmal PhD Instructor of Medicine, DFCI, HMS Laboratory of systems pharmacology Harvard Medical School Dr. Nirmal[/caption] Ajit Johnson Nirmal PhD Instructor of Medicine, DFCI, HMS Laboratory of systems pharmacology Harvard Medical School MedicalResearch.com:  What is the background for this study?  Response: Like many other types of cancers, melanoma arises from gene mutations within cells that impact cell growth and division. These abnormal cells should be rapidly eliminated by our immune system, however, the failure to do so leads to the development of cancer. Hence researchers have long been interested to study the tumor environment that nurtures and sustains these dangerous cells. In the past, researchers have used single-cell technologies to delineate the cell types and cell states that make up the tumor microenvironment. However, the spatial relationships between these cell types and how they organize themselves such as to provide a favorable environment for the tumor to develop remains unknown. In the last couple of years, researchers have developed a new suite of new technologies called spatial omics which includes CYCIF a method that was developed at Sorger lab. Using this method, we can not only measure the molecular information of cells at a single cell level but also their spatial context. This allows us to build a google map like view of the skin with melanoma and study what is exactly happening that allows the tumors to develop.

MedicalResearch.com Interview with: [caption id="attachment_59045" align="alignleft" width="150"]Dr. med. univ. Cornelia Englisch Medical University of Vienna Dr. Englisch[/caption] Dr. med. univ. Cornelia Englisch Medical University of Vienna MedicalResearch.com:  What is the background for this study?  Response: Patients with cancer are at high risk for developing venous thromboembolism (VTE). Venous thromboembolism includes deep vein thrombosis (DVT), when blood clots form in the deep veins of the legs and pulmonary embolism (PE), a potential life-threatening condition when a clot breaks free and lodges in the arteries of the lung. Having a non-O blood type, meaning blood types A, AB or B, is a known risk factor for VTE in the general – non-cancer – population. Interestingly, it is the most common genetic risk factor for thrombosis. If this is also the case in patients with cancer has not been clarified yet. We therefore wanted to assess the role of ABO blood type in cancer-associated thrombosis. To achieve our goal, we utilized the dataset of the Vienna Cancer and Thrombosis Study (CATS); an observational cohort study including adult patients with active cancer.

Over a 5-year period more than 595,000 patients who were eligible to be screened were seen by a UPMC PCP and about 24% of them were screened. We compared the number and thickness (an important indicator of prognosis) of the melanomas diagnosed in those patients who were screened to those who were not screened.

Sesso, ScD, MPH Associate Professor of Medicine Division of Preventive Medicine Brigham and Women's Hospital Dr. Sesso[/caption] Howard D. Sesso, ScD, MPH Associate Professor of Medicine Division of Preventive Medicine Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study? How does the amount of flavanols in the study arm compare to what might be obtained in a typical diet? Response: The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is a randomized, double-blind, placebo-controlled clinical trial that tested the effects of two promising dietary supplements on cardiovascular disease (CVD) and cancer in 21,442 older adults. Cocoa flavanols have been shown to have favorable vascular effects in small and short-term clinical trials. The 500 mg/day flavanols tested in COSMOS exceeds that readily obtained in the diet typically from cocoa, tea, grapes, and berries. Of note, flavanol content in not typically listed on food labels. COSMOS also tested a multivitamin, the most common dietary supplement taken by US adults and previously linked with a potential modest reduction in cancer in a previous long-term trial of men conducted by our research group at the Division of Preventive Medicine at Brigham and Women’s Hospital.

MedicalResearch.com Interview with: [caption id="attachment_58857" align="alignleft" width="125"]Ece Kartal, PhD Postdoctoral Fellow Saez-Rodriguez Group Universitätsklinikum Heidelberg Institute for Computational Biomedicine Heidelberg Dr. Kartal[/caption] Ece Kartal, PhD Postdoctoral Fellow Saez-Rodriguez Group Universitätsklinikum Heidelberg Institute for Computational Biomedicine Heidelberg MedicalResearch.com:  What is the background for this study?    Response: Pancreatic cancer is one of the deadliest types of cancer: although incidence rates are relatively low (only few people develop pancreatic cancer in their lifetimes), it has a high lethality, with a five year survival rate of less than ~5%. Pancreatic cancer symptoms are generally unspecific so that the disease is usually detected very late which further  limits therapeutic options. In light of this, earlier detection of pancreatic cancer could dramatically improve prognosis, but there are currently no affordable and non-invasive tests available in the clinic. For pancreatic ductal adenocarcinoma (PDAC),the most common form of pancreatic cancer, it was previously found that the oral, gut and pancreatic microbiome are risk factors and may affect prognosis .

  • Our mission is to develop medicine and therapeutics that dramatically improve and save the lives of people worldwide suffering from diseases, including cancer.
MedicalResearch.com: What are the advantages of the Single Domain Antibody technology?
  • The average human antibody is 150 Kd in size and works on the outside of the cell. The advantage of the single domain nanobody is that it is significantly smaller, in fact, it is one-tenth the size (approximately 15 Kd) of the human antibody. A smaller nanobody is more useful therapeutically because, unlike many cancer drugs currently on the market, it can penetrate the blood-brain barrier, the blood-retina barrier, and the cell membrane. Moreover, our SBT-100 drug has been shown to be non-toxic in animal models.

MedicalResearch.com Interview with: Dr Rana Conway PhD RNutr  Research Fellow Energy Balance & Cancer Group, and Obesity Research Group Research Department of Behavioural Science and Health University College London    MedicalResearch.com: What is the background for this study? Response: We’ve seen great advances in cancer diagnosis and treatment in recent years which means the number of people living with and beyond a cancer diagnosis is rapidly increasing. The WCRF and CRUK recommend improving diet and exercise to reduce the risks of cancer coming back but we know anecdotally that supplements are sometimes seen as an easier option, and people who’ve had cancer are often interested to know if they should be taking any supplements.

MedicalResearch.com Interview with: Ting Martin Ma, MD, PhD Resident Physician Amar U. Kishan, MD Assistant Professor, Department of Radiation Oncology Vice-Chair of Clinical and Translational Research Department of Radiation Oncology at UCLA MedicalResearch.com: What is the background for this study? Response: We know from epidemiologic studies that  Black men are more likely to be diagnosed with and die of prostate cancer than White men. Recent studies hinted that Black men had better oncological outcome (such as prostate cancer specific mortality and overall survival) responding to systemic therapy for advanced prostate cancer (e.g. cancer that has spread or metastasized to other parts of the body). The question we were trying to answer in this study is: is there a difference in outcomes between Black and White men with localized prostate cancer (cancer that has not spread) receiving definitive radiotherapy enrolled in clinical trials?

Deshmukh, PhD, MPH Associate Professor, Management, Policy & Community Health Associate Director, Center for Health Services Research Co-director, Clinical Analytics and Decision Science Lab UTHealth School of Public Health Houston, TX 77030 MedicalResearch.com: What is the background for this study? Response: Oropharyngeal cancer is the most common cancer caused by human papillomavirus (HPV) in the United States (US). We know from previous studies that oropharyngeal cancer to be one of the fastest rising cancers in the US. However, trends (i.e., extent of change) in incidence rates among men and women in all 50 US states and trends according to tumor diagnostic characteristics (i.e., stage, size) have not been comprehensively studied. In addition, no prior study evaluated contemporary trends in oropharyngeal cancer mortality (death) rates in the US. Our study provides a comprehensive picture of oropharyngeal cancer incidence and mortality (according to age, stage, tumor size, and state of residence) in all 50 states and DC.
Author Interviews, Cancer Research, Dermatology, Lancet, Melanoma, Technology / 11.11.2021

MedicalResearch.com Interview with: [caption id="attachment_58371" align="alignleft" width="150"]Dr David Wen BM BCh NIHR Academic Clinical Fellow in Dermatology University of Oxford Dr. Wen[/caption] Dr David Wen BM BCh NIHR Academic Clinical Fellow in Dermatology University of Oxford MedicalResearch.com: What is the background for this study? Response: Publicly available skin image datasets are commonly used to develop machine learning (ML) algorithms for skin cancer diagnosis. These datasets are often utilised as they circumvent many of the barriers associated with large scale skin lesion image acquisition. Furthermore, publicly available datasets can be used as a benchmark for direct comparison of algorithm performance. Dataset and image metadata provide information about the disease and population upon which the algorithm was trained or validated on. This is important to know because machine learning algorithms heavily depend on the data used to train them; algorithms used for skin lesion classification frequently underperform when tested on independent datasets to which they were trained on. Detailing dataset composition is essential for extrapolating assumptions of generalisability of algorithm performance to other populations. At the time this review was conducted, the total number of publicly available datasets globally and their respective content had not previously been characterised. Therefore, we aimed to identify publicly available skin image datasets used to develop ML algorithms for skin cancer diagnosis, to categorise their data access requirements, and to systematically evaluate their characteristics including associated metadata.

MedicalResearch.com Interview with: [caption id="attachment_58308" align="alignleft" width="200"]Brianna M. Jones, MD Radiation Oncology Resident Icahn School of Medicine at Mount Sinai Dr. Jones[/caption] Brianna M. Jones, MD Radiation Oncology Resident Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Response: The COVID-19 pandemic has resulted in over 4 million deaths worldwide and, presently, there have been over 2 million cases diagnosed in New York. There have been numerous studies that demonstrate cancer patients are at increased risk of diagnosis and mortality to SARS-CoV-2 virus. Several studies have also noted socioeconomic status and race/ethnicity are associated with poorer outcomes. Within NYC, Elmhurst Hospital Center (EHC) emerged as an early epicenter in spring of 2020. The surrounding catchment area of EHC consists of a population that is 54% Latino, 33% Asian, 6% White, 4% Black, 1% Native American, and 1% other according to U.S. Census Bureau, making it one of the most racially and ethnically diverse populations in the country. Its residents are predominantly working-class immigrants with limited resources that work jobs now considered essential (e.g., delivery workers, grocery shops, et cetera). EHC continued to offer a range of cancer services throughout the pandemic. Given the high infection rate and diverse population at EHC, our study provides an opportunity to evaluate outcomes in one of the hardest hit communities to date. Therefore, our aim was to investigate patient characteristics, clinical outcomes, and predictors of COVID-19 diagnosis, severity, and mortality in patients with an active cancer diagnosis at EHC.

Would you briefly describe the Phantosmia phenomenon?  Response: Phantosmia is an olfactive disorder resulting in the perception of a foul-smelling odor without odorant stimulus. This study was spearheaded by Dr. Suzanne Wolden, a pediatric radiation oncologist and the senior author of the research. She noticed that patients receiving proton beam therapy were complaining of this phenomenon more than her patients receiving photon therapy. Through this research, the team hoped to characterize radiation treatment induced phantosmia in pediatric, adolescent and young adult patients treated with proton beam therapy and we hoped to identify potential clinical and treatment-related characteristics that may correlate with the development of phantosmia.

Response: The US Preventive Services Task Force (USPSTF) issued their 2021 recommendation on lung cancer screening lowering the start age from 55 to 50 years and the minimum pack-year criterion from 30 to 20, relative to the 2013 recommendations. Although costs are expected to increase with the expanded screening eligibility, it is unknown if the new guidelines for lung cancer screening are cost-effective.

What are the main findings? Response: The expectation for new cancer drugs is that they help patients live better longer. Increasingly more cancer drugs are approved without documented quality of life or overall survival benefits.   At the same time, cancer drug prices are rising.  We studied use of and spending on selected new cancer drugs among patients with employer-sponsored health insurance. We found that among 37348 patients who received one or more of 44 oral targeted cancer drugs, the proportion of patients who received a drug without documented overall survival benefit increased from 13% in 2011 to 59% in 2018.  By 2018, spending on drugs without documented overall survival benefit accounted for 52% of the $3.5 million spend on the 44 drugs since 2011.

MedicalResearch.com Interview with: [caption id="attachment_58071" align="alignleft" width="225"] Dr. van Winden[/caption] Marieke van Winden MD MSc PhD candidate Dermatology Radboud Institute for Health Sciences Department of Dermatology Radboud University Medical Center Nijmegen, the Netherlands MedicalResearch.com: What is the background for this study? What underlying conditions would factor in a decision for Watchful Waiting?  Response: Basal cell carcinomas are frequently treated because of the risk for progression, which can cause a significant morbidity due to local tissue invasion and destruction. However, most BCCs are characterized by a relatively indolent nature, growing slowly and frequently asymptomatically. Because patients with a limited life expectancy might not live long enough to develop symptoms from basal cell carcinoma progression, they might not live long enough to benefit from treatment. Underlying conditions that determine life expectancy should therefore be considered when weighing BCC management options. When life expectancy is expected to be relatively short, and the consequences of  watchful waiting (WW) are relatively low risk (low tumor burden expected within the remaining lifespan), WW should be considered.

Courneya, PhD Professor and Canada Research Chair in Physical Activity and Cancer Director, Behavioral Medicine Laboratory and Fitness Center Faculty of Kinesiology, Sport, and Recreation | College of Health Sciences University of Alberta | Edmonton, Alberta | CANADA  MedicalResearch.com: What is the background for this study? Response: An increasing number of men with low risk prostate cancer (PCa) do not receive any immediate medical treatments for their PCa. This practice is called active surveillance (AS). It can be very stressful for men because about one-third of them will eventually experience disease progression and require medical treatments. Right now, there is nothing these men can really do for themselves other than to attend all of their follow-up medical visits. Some research has shown that exercise may slow the progression of prostate tumours and metastasis in animal models and improve quality of life in men during and after PCa treatments. Very little research, however, has been conducted in the AS setting. We wanted to see if a high intensity interval training exercise program could improve fitness and prevent or delay biochemical progression of PCa in the AS setting.

Nearly half of patients will eventually experience disease recurrence following nephrectomy and no standard, globally approved adjuvant therapy options are currently available for this population. The phase 3 KEYNOTE-564 study met its primary objective of demonstrating a statistically significant and clinically meaningful improvement in disease-free survival with pembrolizumab vs placebo as adjuvant therapy for patients with RCC post nephrectomy, supporting pembrolizumab as a potential new standard of care for patients at high risk of disease recurrence following surgery.

Barrett’s oesophagus affects about one out of 100 people in the UK and is thought to be a precancerous lesion of a more deadline cancer, oesophageal adenocarcinoma. Barrett’s is a condition where the squamous cells in the lower part of oesophagus are replaced by a special type of columnar cells, which look like intestine, a far distant organ, raising a question where are these columnar cells come from. Many theories have been proposed in the past decades and no agreement was reached, and many conclusions were based on mouse models which do not recap the human condition. We therefore collected fresh samples of human tissues that correspond to all the possible theories and assessed them all together using state of the art technologies.

Response: Unfortunately, it has been well-established that historically Black Americans experience increased cancer specific mortality compared to white patients. In prostate cancer specifically studies have shown that when access to care is equitable this gap resolves. This suggests that biological factors are not driving these differences but rather the result of the complex interplay of social determinants and systemic inequities in our healthcare system. Early in the pandemic, multiple studies demonstrated that minority communities disproportionately shouldered poor COVID-19 outcomes.  On March 13th 2020, the American College of Surgeons recommended against elective procedures; however, the definition of an elective oncologic case was left to the discretion of the provider. As prostate cancer treatment can be safely deferred up to a year follow diagnosis, management of prostate cancer during the initial lockdown period of the COVID-19 Pandemic provided a useful analysis of the differential restrictions placed on non-emergent health care during the Pandemic.

  MedicalResearch.com Interview with: Eleonora Leucci, Ph.D Assistant Professor Laboratory for RNA Cancer Biology Department of Oncology KU Leuven   MedicalResearch.com: What is the background for this study? Response: Back in 2016, while I was characterising the RNA SAMMSON as essential for mitochondrial translation in melanoma, I noticed that its inhibition was causing cell death across a large spectrum of melanoma cell lines and models, irrespectively of their genetic background and cell state. At that time I still did not know why the effect was so pronounced on melanoma cells, but I knew that antibiotics of the tetracycline family could also block mitochondrial translation and I thought about repurposing them to treat melanoma.
