Background: The mechanisms causing hypercortisolism in primary macronodular adrenocortical hyperplasia (PMAH) are not fully clarified. The participation of ectopic receptors and autocrine/paracrine regulation of intra-adrenal ACTH in hyperplastic tissue have been considered. Additionally, germline ARMC5 mutations have been described as main cause of PMAH. So far, the functional study that analyzed the role of ARMC5 used the adrenocortical carcinoma cell line, H295R.

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with an unfavorable prognosis. Despite the poor prognosis in the majority of patients, no improvements in treatment strategies have been achieved. Therefore, the discovery of new prognostic biomarkers is of enormous interest. Sterol-O-acyl transferase 1 (SOAT1) is involved in cholesterol esterification and lipid droplet formation. Recently, it was demonstrated that SOAT1 inhibition leads to impaired steroidogenesis ...
