在致癌过程中 ,端粒酶的重新活化被认为是一个关键步骤。一些有关胃癌端粒酶活性的研究证明 ,端粒酶的重新活化与端粒酶 RNA组分 (h TR)的酶活性和表达有关。然而 ,有关胃癌形成过程中端粒酶活性的调节报道很少 ,尤其是端粒酶亚单位 (h TERT)的表达是否被上调未见报道。因此作 In the process of carcinogenesis, the reactivation of telomerase is considered a key step. Some studies on telomerase activity in gastric cancer have demonstrated that the reactivation of telomerase is related to the enzyme activity and expression of the telomerase RNA component (hTR). However, little is known about the regulation of telomerase activity during gastric cancer formation, especially whether the expression of telomerase subunit (h TERT) is upregulated. Therefore,
