AR signalling can be activated in HR tumours through several mechanisms. First, activation of intracellular signal transduction pathways can sensitize the AR to castrate levels of androgens. Also, mutations in the AR can change AR ligand specificity, thereby allowing it to be activated by non-steroids or anti-androgens. Finally, overexpression of the wild-type AR sensitizes itself to low concentrations of androgens.
HRPC的AR信号通路活化机制包括:胞内信号传导途径可以增加 AR对于去势治疗后低水平雄激素的敏感性;AR的突变也可改变其对于配体的选择,使得非甾体类激素甚至抗雄激素药物也能够激活AR;此外,野生型AR的过表达也促进了自身对于低浓度雄激素的敏感性。
