From left, Kimryn Rathmell, MD, PhD, Bradley Reinfeld, Matthew Madden and Jeffrey Rathmell, PhD, have discovered that immune cells — not cancer cells — are the major glucose consumers in the tumor microenvironment, upending a century-old observation.

Study revises understanding of cancer metabolism

Tumors consume glucose at high rates, but a team of Vanderbilt researchers has discovered that cancer cells themselves are not the culprit, upending models of cancer metabolism that have been developed and refined over the last 100 years.

HIV, diabetes and immune cells in fat

In HIV-positive individuals with diabetes, immune cells in fat are more proinflammatory and cytotoxic and may represent a therapeutic target for diabetes.

Electronic health record study discovers novel hormone deficiency

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.

Probiotic protection

A probiotic factor given early in life to mice prevented intestinal inflammation in adulthood, providing a rationale for probiotic intervention in individuals at high risk of developing inflammatory bowel disease.

Targeting glucagon action in diabetes

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.

Insulin in vials

Gene variant and glucose metabolism

Genetic variation that impacts glucose- and insulin-related signaling affects responses to type 2 diabetes treatments and warrants further study.
