TDG在子宫内膜异位症中的表达

The expression of TDG in endometriosis

目的探讨TDG在内异症中的表达作用,为内异症的研究提出新的思路和方法。方法采用蛋白免疫印迹法测定TDG在23例内异症异位内膜和在位内膜及23例非内异症对照组内膜的蛋白表达。结果 TDG在内异症的异位、在位及对照内膜中均有表达,且蛋白表达量分别为(0.412±0.083,0.366±0.062,0.315±0.069),蛋白表达量均逐渐降低,差别有统计学意义。TDG在异位内膜中的表达量明显高于在位内膜,0.412±0.083 vs 0.366±0.062(P=0.035);TDG在在位内膜中的表达量明显高于对照内膜,0.366±0.062 vs 0.315±0.069(P=0.019);TDG在异位内膜中的表达量明显高于对照内膜,0.412±0.083 vs 0.315±0.069(P<0.001)。结论 TDG在内异症患者中的表达明显增高,表明TDG可能在内异症发生和发展过程中起重要的作用。

Objective：To explore the expression of TDG in endometriosis,and to provide new ideas and ways to study the pathogenesis of endometriosis. Methods：The expression of TDG in 23 cases of endometriosis with ectopic endometrium,eutopic endometrium and 23 cases of non-endometriosis patients with normal endometrium were detected by western blot.Results：TDG expressed in ectopic endometrium,eutopic endometrium and control endometrium,the amount of protein were（0.412±0.083,0.366±0.062,0.315±0.069）,and the expression of proteins decreased gradually,the difference was statistically significant.The expression of TDG in the ectopic endometrium was significantly higher than that in eutopic endometrium,0.412±0.083 vs 0.366±0.062（P=0.035）.The expression of TDG in eutopic endometrium was significantly higher than that in control endometrium,0.366 ± 0.062 vs 0.315 ± 0.069,（P=0.019）. The expression of TDG in ectopic endometrium was significantly higher than that in control endometrium,0.412±0.083 vs 0.315±0.069,（P 0.001）.Conclusion：The expression of TDG in endometriosis patients were significantly increased. These results suggest that TDG play an important role in the occurrence and development of endometriosis.
