Adrenocortical carcinomas (ACC) overexpress the insulin-like growth factor 2 (IGF2) that drives a proliferative autocrine loop by binding both IGF1R and isoform A of insulin receptor (IRA). However, the contribution of these receptors in mediating ACC cell growth has been poorly investigated. The aim of this study was to investigate IGF1R and IR expression and localisation in ACC and adrenocortical adenomas (ACA) samples, and to test their involvement in mediating IGF2 tumorig...
