In the context of the Center for Adipocyte Signaling (ADIPOSIGN), the Mandrup Group investigates how adipocytes receive and respond to signals at the level of the transcriptome and epigenome and how these signals differ between adipocytes from different depots, sex and metabolic health. Adipocytes are highly plastic cells with an enormous capacity to adapt to the metabolic need of the body. Several lines of evidence have indicated that the ability of adipocytes to adapt and maintain basic metabolic- and signaling functions is essential for metabolic health. Thus, loss of adipocyte function in obesity is considered a primary driver of obesity comorbidities. We study how changes in signaling states of adipocytes during development of obesity contribute to the adaptation of adipocytes as well as the pathophysiological consequences of obesity.

Technologies: We isolate adipocytes from human subjects with a wide range of BMI and metabolic health and from mouse models challenged with obesogenic diet and use functional genomics technologies to study gene regulatory networks and how these are affected by metabolic signals.

This project is supported by a grant from The Novo Nordisk Foundation.
