中文摘要: 去势抵抗性前列腺癌(CRPC)是前列腺癌治疗的难点和挑战。本课题组通过前期工作首次报道了MAZ可反馈调控与前列腺癌去势抵抗高度相关的雄激素受体(AR)表达,对CRPC细胞具有促进增殖的作用。但其参与CRPC发展的具体分子通路和调节机制还不清楚。我们推测MAZ可能通过AR及非AR通路,促进CRPC细胞增殖生长,导致侵袭转移。我们拟应用前列腺癌细胞模型和前列腺癌小鼠模型,通过现代分子生物学的方法,探讨MAZ调节AR活性及通过非AR通路对CRPC进展的影响,观察沉默MAZ抑制CRPC进展的可行性,为揭示CRPC发生发展相关分子机制和信号通路奠定理论和实验基础。本课题的成功实施有望为治疗CRPC提供新的分子靶点,具有重要的科学意义和应用价值。

英文摘要: Castration resistant prostate cancer (CRPC) brings patients difficultis and challenges during prostate cancer therapy. Our previous study demonstrates that MAZ regulates the expression of androgen receptor(AR),which is highly correlated to castration resistant procedure of prostate cancer. The result shows that MAZ promotes the proliferation of CRPC cells without AR. However, the effect and mechanism of MAZ for CRPC progression remains undefined.We hypothesize that MAZ promotes CRPC proliferation and led to Invasion and metastasis through AR or non-AR passway. With modern molecular biology methods, we are programming to assess the effect of MAZ for CRPC in cell models and mouse models by AR/non-AR passway,and evaluate the viability of Inhibition of CRPC progress by knocking down MAZ genes. Thus the study may reveal the theoretical foundation and experiment evidence for exploring the mechanism and pathways of CRPC progression, which could provide new molecular target for CRPC therapy.
