The melanocortin system is significant for energy homeostasis and receptors have distinct tissue specific expression. The melanocortin 2-receptor (Mc2r) transmits ACTH dependent signalling in the adrenal cortex. Increased expression in adipocytes during differentiation indicates relevance for lipid homeostasis. Mc2r activation in adipocytes results in increased lipolysis, however, implication compared to norepinephrine (NE) stimulated lipolysis is unknown. To further define fu...

To maintain a proper lipid composition of cellular membranes is fundamental for cell viability and intracellular signalling. Therefore we hypothesised the existence of membrane quality control homeostatic mechanisms. Previously, we have shown that Pyruvate Carboxylase (PC), an enzyme involved in de novo lipogenesis and fuel partitioning, is a target of PPARĪ³ and that PC level is decreased in PPARĪ³ KO and obese insulin resistant mouse models. Here, we used RNAi...
