糖皮质激素受体信号通路在膀胱癌治疗中的作用研究进展

摘要

糖皮质激素受体( GR)是核受体家族中的一员,结合配体后的受体会从细胞质中转位进入细胞核,通过对相关基因转录信号的调控发挥生物学作用。临床上,使用糖皮质激素产生的治疗效果和不良反应几乎都是通过GR信号通路实现的。越来越多的研究表明,GR信号通路与膀胱癌的增殖、侵袭性和预后密切相关,而新一代GR选择性激动剂在提升糖皮质激素抗肿瘤作用的基础上,大大减少了不良反应,有望成为膀胱癌治疗的新方法。%Glucocorticoid receptor ( GR ) is identified as a member of nuclear receptor family. To exert its biological action, the ligand bound GR is translocated from the cytoplasm into the nucleus by regulating transcriptional signals of related genes. In clinical practice, the effects of glucocorticoid are often mediated by GR signaling pathways. An increasing number of studies have indicated that GR signaling pathways play an essential role in the proliferation, invasion and prognosis of bladder cancer. Meanwhile, the new-generation selective GR activator improves its anti-tumor effects, and at the same time reduces the adverse reactions of hormones, which probably raises the prospect for the treatment of bladder cancer.
