Mathur Lab

The Mathur Laboratory, led by Ruchi Mathur, MD, studies the effects of gastrointestinal microbiota on metabolic diseases such as obesity and diabetes. Defining the role of specific gut flora in the development of obesity and insulin resistance is the focus of the Mathur Lab as well as understanding the effects of the intestinal microbiome on metabolism. In addition to gut bacteria, the Mathur Lab also studies polycystic ovary syndrome and the clinical phenotyping of this disorder.

The Mathur Laboratory is affiliated with the Cedars-Sinai Department of Medicine and the Endocrinology Program.

Microbial fermentation in the human gut. (A) In the absence of H2-utilising methanogens, the build-up of H2 results inhibition of fermentation. (B) In the presence of H2-utilising methanogens, H2 build-up is alleviated, facilitating increased polysaccharide fermentation and increased availability of SCFAs to the host. CH, carbohydrate.

Personal Statement

As an academic endocrinologist, I have a specific interest in the relationship between the gastrointestinal tract and the endocrine system. My early projects focused on gastric myoelectrical activity and glycemic control. In collaboration with researchers in the Division of Gastroenterology, we published the first paper confirming a clinical association with polycystic ovary syndrome (PCOS) and irritable bowel syndrome (IBS)."
