Background: The adrenal gland produces corticosteroids essential for hydromineral and metabolic homeostasis. It is organised, in mice, in two concentric layers. The zona glomerulosa (zG) and fasciculate (zF), renewed from progenitors located in the capsular periphery. Centripetal renewal and maintenance of cortical zonation are dependant of a balance between WNT/β-catenin and ACTH/PKA signalling pathways. They provide recruitment and consecutive differentiation of progeni...

Background: Adrenocortical carcinoma (ACC) is an aggressive cancer originating from steroidogenic cells within the adrenal cortex. Unfortunately, half of patients present with metastatic spread upon initial diagnosis, and there is no curative therapy for advanced disease. Genomic analysis has identified that the most aggressive subgroup of ACC patients have overlapping alterations in the WNT/β-catenin pathway and the p53/RB signaling pathway.Objecti...
