Would you briefly explain how mitochondrial DNA differs from chromosomal DNA? TK: Immune checkpoint blockade has changed the way we treat several cancers, including advanced melanoma. Before these therapies, the treatment options were very limited, but now more than half of patients experience significant tumor shrinkage or disease control. KRM: Despite these advances, many patients still do not respond to treatment. One of the main challenges in cancer medicine today is to find ways to predict which patients will benefit from these therapies before treatment begins. This approach is key to personalizing care and improving outcomes. RF: Mitochondria are small structures inside our cells that produce the energy needed for cells to function. Unlike most of our DNA, mitochondrial DNA is inherited only from the mother. Scientists can categorize this mitochondrial DNA into groups called haplogroups, based on unique variations in the genetic code. These haplogroups can provide insight into how cells produce energy and may affect a person’s health or response to cancer treatment.

  Dr. Thomas Deliberto, PhD, DVM, APHIS Wildlife Services One Health Coordinator     MedicalResearch.com: What is the background for this study? deer-covidResponse: In 2021, USDA launched a plan to investigate exposure of wild white-tailed deer (Odocoileus virginianus) to SARS-CoV-2, a zoonotic virus and the virus that causes COVID-19. Researchers found that 40% of the blood samples tested had SARS-CoV-2 antibodies. This initial study suggested that SARS-CoV-2 could be transmitted from humans to deer, and that deer could potentially serve as a reservoir for the virus. To better understand the transmission of SARS-CoV-2 in white-tailed deer, a team of researchers conducted a larger study to collect and analyze respiratory samples from free-ranging white-tailed deer in the United States.  The study identified SARS-CoV-2 sequences in white-tailed deer across nearly half of the states in the U.S. The researchers also found that deer could be infected with multiple SARS-CoV-2 lineages, and that these lineages could be transmitted from deer to deer. In addition, the researchers found three cases of potential virus transmission from white-tailed deer back to humans.  This raises concerns about the potential for the virus to continue to evolve in an animal reservoir, and the possibility of future spillover events.

Would you describe the Rareservoir database? Response:   The main motivation for our work is that only half of the approximately 10,000 catalogued rare diseases have a resolved genetic cause (or aetiology). Patients with these diseases are unable to obtain a genetic diagnosis which could otherwise inform prognosis, treatment for themselves and affected relatives. One route towards resolving the remaining aetiologies is to enroll large numbers of rare disease patients into research studies so that statistical analyses can be performed comparing the genetic with the clinical characteristics of the study participants. One major endeavour, the 100,000 Genomes Project (100KGP), sequenced the genomes and collected clinical phenotype data for 34,523 UK patients and 43,016 unaffected relatives across 29,741 families. The scale of this study is unprecedented, partly thanks to the ever-decreasing cost of DNA sequencing (25 years ago, it cost $1bn to sequence a whole genome, while now it costs only a few hundred dollars). Working with such large datasets is notoriously cumbersome. To overcome this, we developed a computational approach (the Rareservoir) that distills the most important information into a relatively small database, allowing us to apply our statistical methods nimbly. We noted that the "genetic variants" that cause rare diseases are typically kept rare in the human population by natural selection because affected individuals tend to have few children, if any. This meant that we could discard the genetic information corresponding to variants that are common in the human population without throwing away the key disease-causing variants. By focussing on these "rare variants", we were able to perform our analyses using a small database (a `Rareservoir’), only 5.5GB in size, hastening our progress significantly.

Response: For men, the only two options for birth control currently available are condoms and vasectomy. Additional contraceptive methods are required to more equally distribute the burden of contraception between men and women. We aim to develop an on-demand contraceptive pill for men where sperm motility and thereby fertility is only blocked for multiple hours. The idea is that men take our contraceptive shortly before intercourse and regain fertility about 24 hours later.

What are the main findings? Response: The background of this study is that we tried to build a structure that looks and develops like a real mouse embryo using different kinds of mouse stem cells. The main findings are that the resulting structures develop the entire embryonic body axis and the extraembryonic tissues that are required to support embryonic development. Our structures develop to a stage comparable to 8.5 days of embryonic development of the natural mouse embryos and have a brain and neural tube, a beating heart-like structure, gut and primordial germ cells.

MedicalResearch.com Interview with: [caption id="attachment_59198" align="alignleft" width="200"]Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine  Rogel Cancer Center Ann Arbor, MI, 48109 Prof. Shureiqi[/caption] Imad Shureiqi, MD, MS Professor, Division of Hematology and Oncology Department of Internal Medicine Rogel Cancer Center Ann Arbor, MI, 48109 MedicalResearch.com:  What is the background for this study?   Response: Pancreatic ductal adenocarcinoma is a highly lethal form of cancer with rising occurrence, and strategies to prevent and treat the disease are urgently needed. Most cases of pancreatic cancer arise from pre-cancerous lesions called pancreatic intraepithelial neoplasia (PanIN); about 55-80% of adults over forty are estimated to have these low-grade pre-cancerous silent pancreatic lesions. But critical factors that promote the progression of pancreatic pre-cancerous lesions to pancreatic cancer remain poorly defined, especially those easy to target. Findings from this publication indicate that people who have silent PanIN pre-cancerous lesions, even those that are low-grade, could increase their risk of PanIN progression into pancreatic cancer by consuming activators of a nuclear lipid receptor called peroxisome proliferator-activated receptor-delta (PPARδ). PPARδ activators can be natural substances, such certain fatty acids like palmitic and arachidonic acid in high-fat diets, or synthetic ones, like Cardarine (GW501516).

MedicalResearch.com Interview with: [caption id="attachment_59073" align="alignleft" width="150"]Michael B. Miller, MD, PhD Instructor, Harvard Medical School Department of Pathology Brigham and Women's Hospital Dr. Miller[/caption] Michael B. Miller, MD, PhD Instructor, Harvard Medical School Department of Pathology Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study? Would you explain what is meant by somatic genetic changes and how they might occur?  Response: Changes, also called mutations, in the DNA sequence of genes can be passed from parents to their children, and explain why many diseases run in families. This kind of DNA change is called a germline mutation and is present in every cell in a person’s body. Gene mutations can also occur in a subset of cells of a person, in which case they are called somatic mutations. Somatic mutations are well known as a cause of cancer, and recent research has found that somatic mutations can also happen in non-cancerous cells that appear otherwise normal. Recent studies have even found that somatic mutations are present in neurons, cells in the brain that transmit electrical signals and play an important role in how the brain functions. Furthermore, in neurons, somatic mutations increase with age, so we set out to understand if somatic mutations might be playing a role in age-related brain diseases like Alzheimer’s.

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.

In 2016, there were more than 650 million adults aged 18 and above with obesity. Obesity can lead to increased fat in the blood which damages tissues and organs, contributing to the development of cardiovascular and metabolic diseases including type 2 diabetes. This elevated blood fat can damage the cellular organelle responsible for making protein, the endoplasmic reticulum, causing the cell to come under stress and potentially resulting in the cell dying. When this occurs in skeletal muscle it can contribute to features of the metabolic syndrome including metabolic dysfunction and insulin resistance.

In general, adherence to standard guidelines for lipid lowering therapy is low - about 30% of people who should be on lipid lowering therapy are, with no correlation to their genetic risk. We set out to see whether communicating personalized risk, including polygenic risk, for coronary artery disease would drive the adoption of lipid lowering therapy.

MedicalResearch.com Interview with: Laura Rupprecht, PhD Postdoctoral Fellow Kelly L Buchanan The Laboratory of Gut Brain Neurobiology Duke Medicine – GI Diego V. Bohórquez PhD Associate Professor in Medicine Duke Institute for Brain Sciences Durham, NC MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: In 2018, my laboratory discovered that a cell type in the gut epithelium synapses with the vagus nerve, the nerve which connects the gut and the brain. These gut cells are called neuropod cells. Neuropod cells transduce sugar within milliseconds using the neurotransmitter glutamate. Since then, we have been interested in defining how this rapid communication between neuropod cells and the brain regulates behavior. – Diego Bohórquez Over a decade ago, it was shown that the gut is the key site for discerning sugar and non-caloric sweetener. But the specific cell in the gut that underlies this effect was unknown. – Kelly Buchanan

Where is triclosan commonly found? Response: Triclosan is a commonly found antibacterial compound present in hand soaps, toothpastes, athletic clothes, and children’s toys. A previous study by the Zhang group (corresponding author on this publication) found that antimicrobial compounds including triclosan increased inflammation (similar to that of inflammatory bowel disease (IBD)) and tumor formation in the colon. These effects were observed only in mice with an intact gut microbiome, not in germ-free mice which lack a gut microbiome, suggesting that the gut microbiome is somehow responsible for the toxicity of triclosan to the gut. Our study investigates how gut bacteria promote triclosan toxicity in the gut

Response: There has been growing evidence of the benefits of fecal transplants in some medical conditions, like cancer, hypertension and obesity for several years. In fish, it’s been shown that their lifespan could be extended significantly after fecal transplant from young fish. When we found an impact on cognitive function in mice from a fecal transplant, we decided to research and isolate how that biological mechanism was implemented.
