中文摘要: 细胞衰老在肿瘤预防中有重要作用,并已成为肿瘤治疗靶标。但有关衰老在子宫内膜癌中的抗癌机制未引起关注。胰岛素样生长因子结合蛋白-相关蛋白1(IGFBP-rP1)是一个能抑制细胞增殖、诱导细胞衰老的肿瘤抑制基因,而我们前期研究工作发现孕激素能通过调节IGFBP-rP1的表达影响子宫内膜癌进展。本研究拟以IGFBP-rP1为切入点,明确IGFBP-rP1在子宫内膜癌中的致衰老机制,及孕激素诱导下对子宫内膜癌细胞致衰老效果的影响,阐明孕激素在IGFBP-rP1通路上抑制子宫内膜癌发展的可能基因模块,为临床提供预防、控制或治疗子宫内膜癌的靶标。

英文摘要: Cellular senescence plays essential role in cancer prevention. Prosenescence become the promising new targets for cancer treatment. However, the roles of cellular senescence remain unknown in the initation, progression and intervention of endometrial cancer. Insulin-like growth factor binding protein-related protein 1 (IGFBP-rP1) is a tumor suppressor gene, which could inhibit cellular proliferation and induce cellular apoptosis. Our preliminary work has found that progesterone can inhibit enmdometrial cancer cell growth via upregulating IGFBP-rP1 expression. Here we want to futher explore the the mechanism of IGFBP-rP1 in cellular senescence of endometrial cancer. We will focus on the effects of progestogen on IGFBP-rP1-induced cellular senescence with a specific aim to investigate the possible regulators of progestogen on preventing the endometrial cancer development and progression. Our study will provide theoretical basis for endometrial cancer treatment.
