New topic

Our interest is to understand how hormones and nutrients are sensed by the hypothalamus and how the brain controls systemic metabolism. In rodent models of obesity and in type 2 diabetes this brain control of metabolism is impaired and we believe this dysfunction plays an important role in the pathogenesis of both of these conditions. Interestingly, diabetes and obesity are associated with a pro-inflammatory state. We have found that hormones like insulin and leptin regulate systemic inflammation via the brain and the autonomic nervous system and speculate that this may be the basis for the link between impaired metabolic control and inflammation. A commonly used approach in our lab is to study nutrient fluxes with clamp studies combined with metabolic tracers in rodents.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Buettner did not report having any of the following types of financial relationships with industry during 2012 and/or 2013: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at Patients may wish to ask their physician about the activities they perform for companies.
