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...

Aldosterone-producing adenomas (APAs) are the most frequent cause of primary aldosteronism (PA). Somatic mutations of KCNJ5, ATP1A1, CACNA1D and ATP2B3 are involved in APAs formation while CTNNB1 and GNAS somatic mutations have been described in both APAs and in cortisol-producing adenomas (CPAs). In contrast, mutations of PRKACA coding for the catalytic subunit of protein kinase A have been yet only identified in ...
