Vanderbilt University Medical Center has opened a state-of-the-art automated biobanking system that can store as many as 10 million biospecimens, including blood and body fluids, tissue, and genetic and protein material, at temperatures down to minus 80 degrees Celsius. The “BioStore” was purchased from its manufacturer, Massachusetts-based Azenta Life… Read More

The growth of epithelial ovarian cancer, one of the most lethal malignancies, is associated with the presence of tumor-associated macrophages (TAMs), white blood cells that can block the anti-cancer activity of the immune system and immunotherapy. Fortunately, TAMs can be “repolarized,” converted from immunosuppressive tumor-promoters to inflammatory tumor-fighters. Now,… Read More

Bacteria in our bodies bind to various host cell surface receptors, which determines where the bacteria live and how they behave. These receptors, made up of chains of sugar molecules called glycans, are more than meets the eye. Cells existing within progressive disease states like cancer can have an increased… Read More

Vanderbilt researchers have developed an active machine learning approach to predict the effects of tumor variants of unknown significance, or VUS, on sensitivity to chemotherapy. VUS, mutated bits of DNA with unknown impacts on cancer risk, are constantly being identified. The growing number of rare VUS makes it imperative for… Read More

In Grapevine, Arkansas students spent more than two hours on the school bus every day for years. Local scientist Billy Hudson saw that time as an opportunity to create a “magic” school bus with internet and computers where students could spend time learning. Now, more than a decade later, Hudson… Read More

Researchers at Vanderbilt University Medical Center have discovered a potential new target in the fight against colorectal cancer, the nation’s third most common malignancy and, next to lung cancer, the second leading cancer killer. This month in the journal Gastroenterology, R. Daniel Beauchamp, MD, Anna Means, PhD,… Read More

New research from Vanderbilt investigators suggests that clinicians should take a deeper dive into distinguishing EGFR mutations when prescribing targeted therapies for non-small-cell lung cancers. EGFR exon 19 deletion mutations are the most common EGFR mutations in patients with lung cancer. However, the term “exon 19 deletion” is a catch-all… Read More

The bacterium Clostridioides difficile (C. difficile), which causes severe diarrhea and an estimated 400,000 infections annually in the United States, may be a previously unrecognized contributor to colorectal cancer. The findings from human colon cancer specimens, culturing, and mouse models were reported last month by researchers at Johns Hopkins… Read More

Alyssa Hasty, Cornelius Vanderbilt Professor of Molecular Physiology and Biophysics, specializes in immunometabolism, specifically on the role that the immune system plays in obesity and metabolic disease. Recent work from her lab explored the changes in immune cell populations in fat during obesity, weight loss, and weight cycling. The work,… Read More
