Background: The reserve pool of primordial follicles (PMF) is finely regulated by molecules implicated in follicular growth or PMF survival. Anti-Müllerian Hormone (AMH), produced by granulosa cells of growing follicles, is known for its inhibitory role in the initiation of PMF growth. We observed in a recent in vivo study that injection of AMH into mice seemed to induce an activation of autophagy, a cytoplasmic lysosomal-dependent degradation system, which is im...

Bone morphogenetic proteins (BMPs) exhibit broad spectrum of biological activities in various tissues, including bone, cartilage, blood vessels, heart, kidney, neurons, liver and lung. BMPs are members of the transforming growth factor-β (TGF-β) family that bind to type II and type I serine-threonine kinase receptors, and transduce signals through Smad and non-Smad signalling pathways. BMPs together with other intraovarian growth factors are intimately involved in re...

Context: Primary bilateral macronodular adrenal hyperplasia (PBMAH) with glucose-dependent insulinotropic polypeptide (GIP)-dependent Cushing’s syndrome is caused by ectopic expression of GIP receptor in the adrenal tissue. The bilateral nature of this adrenal disease suggests germline genetic predisposition. We aimed to identify the molecular driver event responsible for ectopic GIP receptor expression in PBMAH.Methods: We conducted an internationa...
