摘要
端粒维持基因在保持端粒稳定、维护染色体完整方面起重要作用,端粒功能紊乱将会导致肿瘤发生。在维持端粒稳定的基因中,已经发现多种基因存在单核苷酸多态性。随着研究的深入,越来越多的证据表明,个体间端粒稳定性及长度的差异主要取决于端粒维持基因的多态性。端粒维持基因单核苷酸多态性可能是导致端粒长度及稳定性存在个体差异及增加肿瘤易感性的主要因素之一。本文就端粒维持基因多态性与膀胱癌易感性关系的研究进展作一综述。
Telomere maintenance genes play an important role in maintaining the integrity of the telomere structure that protects chromosome ends, and telomere dysfunction may lead to tumorigenesis. Genetic variation in telomere maintenance genes has been confirmed. Cumulative evidence shows that the difference of telomere length and stability among the individual depends on the genetic variants of telomere maintenance genes. Genetic variants in telomere maintenance genes may affect telomere length and stability, thus the increased cancer risk. This review intends to summarize the association of genetic variants in telomere maintenance genes with bladder cancer risk.
