Overview

Two of the major factors predisposing to cardiovascular disease are diabetes mellitus and dyslipidemia. The Birnbaum lab tries to understand the normal pathways regulating hepatic lipid synthesis and secretion and how these processes are disrupted in insulin resistant states.

Research Projects

The Birnbaum Lab is researching the pathways that regulate hepatic lipid synthesis and secretion and the effect on these pathways of insulin resistance. Currently, the primary focus of the Lab's investigations include the regulation of de novo lipogenesis by the protein kinase Akt; control of lipoprotein secretory pathway by rapamycin complex 1 (mTORC1); and the role of AMP-activated protein kinase (AMPK) in lipid metabolism. Both Akt and AMPK are signaling molecules involved in the pathways that alert an organism to the absence of food and initiate an appropriate response. The mTORC1 complex, a downstream target positively regulated by Akt, is required in vivo for de novo lipogenesis and the expression of Srebp1c, a bHLH transcription factor that controls lipogenesis.
