ACTH inhibits A Ras-dependent anti-apoptotic and mitogenic pathway in mouse Y1 adrenocortical cells.

Abstract:

:Mouse Y1 adrenocortical tumor cells harbor amplified and overexpressed c-Ki-ras gene, displaying relatively high constitutive levels of Ras x GTP. Here we report that Y1 cells also constitutively display high levels of phosphorylated AKT/PKB, that are dependent on Ras x GTP and PI3K. ACTH rapidly causes dephosphorylation of AKT/PKB in a cAMP/PKA dependent maner. This ACTH inhibition of the anti-apoptic and mitogenic AKT/PKB pathway is likely to be relevant in ACTH growth inhibitory effects in Y-adrenocortical cells.
