【摘要】：目的:探討SRPX2在人子宮內膜癌中的表達及生物學功能。方法:收集50例子宮內膜癌及癌旁組織,免疫組化染色法檢測SRPX2的表達,分析SRPX2表達與患者臨床特點的關系。通過si RNA下調HEC-1A細胞中SRPX2的表達,檢測HEC-1A細胞增殖及凋亡改變。檢測沉默SRPX2后細胞內FAK及Cyclin D1表達改變。結果:SRPX2在子宮內膜癌組織中表達明顯升高并與腫瘤直徑增大及高FIGO分期(Ⅲ+Ⅳ期)顯著相關(P0.05);沉默SRPX2表達可顯著抑制HEC-1A細胞的增殖并促進凋亡,并導致細胞中FAK及Cyclin D1的表達降低。結論:子宮內膜癌組織中高表達的SRPX2與腫瘤增殖關系密切,沉默SRPX2可能通過下調FAK/Cyclin D1的表達而抑制子宮內膜癌細胞增殖并促進凋亡。
[Abstract]:Objective: to investigate the expression and biological function of SRPX2 in human endometrial carcinoma. Methods: the expression of SRPX2 was detected by immunohistochemical staining in 50 cases of endometrial carcinoma and paracancerous tissues, and the relationship between the expression of SRPX2 and the clinical characteristics of the patients was analyzed. The expression of SRPX2 in HEC-1A cells was down-regulated by si RNA, and the proliferation and apoptosis of HEC-1A cells were detected. The expression of FAK and Cyclin D1 in cells after silencing SRPX2 was detected. Results: the expression of SRPX2 was significantly increased in endometrial carcinoma and significantly correlated with the increase of tumor diameter and high FIGO stage (stage III IV) (P 0.05). The expression of silent SRPX2 could significantly inhibit the proliferation and promote apoptosis of HEC-1A cells, and lead to the decrease of the expression of FAK and Cyclin D1 in the cells. Conclusion: the high expression of SRPX2 in endometrial carcinoma is closely related to tumor proliferation. Silent SRPX2 may inhibit the proliferation and promote apoptosis of endometrial cancer cells by down-regulating the expression of FAK/Cyclin D1.
