Hippo-YAP信号通路与神经胶质瘤OA
Hippo-YAP signaling pathway and glioma
Hippo-YAP信号通路是进化高度保守的信号通路,在调节组织稳态和肿瘤进展中发挥关键作用,其异常激活与神经胶质瘤的恶性演进密切相关.神经胶质瘤是人类常见颅内恶性肿瘤,占所有恶性脑肿瘤的80%,尽管采用手术治疗及辅助放化疗,但患者术后仍复发率高、预后差.在胶质瘤中,Hippo-YAP信号通路的效应因子Yes相关蛋白(Yes-associated protein,YAP)/含PDZ结合基序转录共激活因子(transcriptional co‑activator with PDZ‑binding motif,TAZ)呈高表达并发挥促癌作用,核心激酶哺乳动物STE20样蛋白激酶1/2(mammalian sterile‑20‑like kinase 1/2,MST1/2)、大肿瘤抑制激酶1/2(large tumor‑suppressor kinase 1/2,LATS1/2)表达下调,二者通过调控YAP/TAZ活性参与胶质瘤恶性进展.此外,Hippo-YAP信号通路参与重塑胶质瘤免疫微环境,维持胶质瘤干细胞的干性与表型异质性.世界卫生组织中枢神经系统肿瘤新分类提出后,YAP/TAZ活性随胶质瘤分子亚型存在显著差异,靶向Hippo-YAP信号通路可逆转化疗耐药、抑制肿瘤恶性表型.深入探究YAP/TAZ在胶质瘤中的调控机制,优化其临床治疗转化策略,有望为改善胶质瘤患者的临床结局、提高生存率提供新的方向.
The Hippo-YAP signaling pathway is a highly evolutionarily conserved signaling cascade that plays a critical role in regulating tissue homeostasis and tumor progression.Its aberrant activation is closely associated with malignant progression of glioma.Glioma is one of the most common intracranial malignant tumors in humans,accounting for approximately 80%of malignant brain tumors.Despite advances in surgical resection and adjuvant chemoradiotherapy,patients continue to experience high postoperative recurrence rates and poor prognosis.In glioma,the downstream effectors of the Hippo-YAP signaling pathway,Yes-associated protein(YAP)and transcriptional co‑activator with PDZ‑binding motif(TAZ),are highly expressed and exert oncogenic functions.Meanwhile,the expression levels of the core kinases mammalian sterile‑20‑like kinase 1/2(MST1/2)and large tumor suppressor kinase 1/2(LATS1/2)are decreased.These components regulate YAP/TAZ activity and contribute to malignant progression of glioma.In addition,the Hippo-YAP signaling pathway participates in remodeling the glioma immune microenvironment and maintaining the stemness and phenotypic heterogeneity of glioma stem cells.Following the introduction of the new World Health Organization classification of central nervous system tumors,substantial differences in YAP/TAZ activity have been identified among molecular subtypes of glioma.Targeting the Hippo-YAP signaling pathway may reverse chemoresistance and suppress malignant phenotypes of glioma.Further investigation of the regulatory mechanisms of YAP/TAZ in glioma and optimization of translational therapeutic strategies may provide new directions for improving clinical outcomes and survival of patients with glioma.
