Discovery offers insight for development of cancer therapies targeting mutant p53

Vanderbilt researchers have discovered that aneuploidy (an abnormal number of chromosomes) drives malignant phenotypes in cells expressing mutant p53, a tumor suppressor protein that is mutated in more than half of all human cancers.

Study shows gene-drug interactions are common

When a drug or combination of drugs causes different responses in different people, genetic variation is often at play. Pharmacogenomics, through discovery of genetic risk and use of clinical genotyping, aims to reduce trial-and-error approaches to drug prescribing.

Autoimmunity advance

Vanderbilt researchers have developed a high-throughput screening method to identify and characterize antigen-specific B cells — potential biomarkers for autoimmune disease and targets for new treatments.

Estrogen, depression and menopause

A shift in emotional processing may help women adapt to lower estrogen after menopause —unless they have a history of major depressive disorder, Vanderbilt researchers have found.

COVID-19 antibody ‘cocktail’ discovered at VUMC protects chronically ill: study

A monoclonal antibody cocktail against the COVID-19 virus discovered at Vanderbilt University Medical Center and developed by AstraZeneca reduced the risk of symptoms in a study of immunocompromised and chronically ill adults later exposed to the virus by 77%, the company announced today.

Potential protection from atherosclerosis

Vanderbilt researchers have discovered a potential way to reduce atherosclerosis: blocking the modification of an HDL-associated enzyme by reactive molecules called isolevuglandins.
