Origin and Identity of Adrenocortical Tumors in Inhibin Knockout Mice: Implications for Cellular Plasticity in the Adrenal Cortex
28 Jul 2006
Abstract excerpt
Inhibin knockout (Inha-/-) mice develop gonadal sex-cord tumors and--when gonadectomized--adrenocortical tumors. Previous reports demonstrated that adrenocortical tumors from Inha-/- mice produce estrogen and depend on gonadotropin signaling for initiation. Here we show that, in addition to producing estrogen, the adrenocortical tumors display a global change in cellular identity, composed of two unique cell...
