Adrenocortical carcinoma (ACC) is an infrequent and aggressive cancer that originates from steroidogenic cells within the adrenal cortex. Half of patients present with metastatic spread at initial diagnosis, and to date, there is no curative therapy for advanced disease. Recent genomic analysis has established that the most aggressive subgroup of ACC patients have overlapping alterations in the WNT/B-catenin pathway and the p53/RB pathway. We therefore set out to develop a met...

Adrenocortical carcinoma (ACC) is a rare and aggressive cancer that originates from steroidogenic cells within the adrenal cortex. The most common alteration in ACC patients is inactivation of the transmembrane E3 ubiquitin-ligase Zinc and Ring Finger 3 (ZNRF3), which is responsible for inhibiting the canonical WNT/Beta-catenin pathway. Using Cre/loxP strategy, we showed that inactivation of Znrf3 in the adrenal cortex resulted in an initial hyperplasia by 6-weeks, af...
