Biochemical and functional analysis of nuclear receptors as targets in cAMP-dependent control of bovine CYP17.

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 dephosphorylat...
