Triple-negative breast cancer cells engage in a “glutamine steal” — outcompeting T cells for the nutrient glutamine and impairing their ability to kill tumor cells, Vanderbilt researchers have discovered.

A novel hormone deficiency may exist in humans, Vanderbilt investigators have discovered. In an analysis of two decades worth of electronic health records, the researchers found that some patients have unexpectedly low levels of natriuretic peptide hormone in clinical situations that should cause high levels of the hormone.

Disrupting the action of glucagon — a pancreatic hormone that works to raise blood glucose — restores functional insulin-producing cells in mouse models of type 1 diabetes and may be a promising treatment strategy.

A selenium transport protein produced in the colon may be a novel biomarker for assessing disease severity and cancer risk in patients with inflammatory bowel disease.

Small RNAs — short stretches of genetic material — from microbes may be playing a role in rheumatoid arthritis and other autoimmune diseases.

A team of Vanderbilt investigators has discovered that blocking a certain signaling pathway boosts antitumor immunity and reduces tumor growth and metastasis in models of breast cancer and melanoma.

Vanderbilt researchers demonstrate that the polymer P188 has promise as a therapy to prevent reperfusion injury — the cellular damage that occurs when blood flow returns after an ischemic event like a heart attack.
