Abstract
The catalytic subunit telomerase reverse transcriptase (hTERT) is a prerequisite for malignant transformation of human cells. Colorectal cancer (CRC) is a common malignant tumor. The genetic association of hTERT gene rs2853669 and rs2736098 polymorphisms with CRC was surveyed in the Chinese population. Two hundreds patients with CRC and 200 healthy controls were taken for blood sample collection. Sanger sequencing was applied for genotyping. Multiple logistic regression analysis was performed, and odds ratio (OR) together with confidence interval (CI) were calculated to obtain the corresponding association power. Among CRC cases (49.50%), hTERT gene rs2736098 GA genotype carriers were more prevalent compared with the control group (41.00%, P = 0.035), which increased the risk of CRC by 1.576 times (95% CI, 1.031-2.409). Distribution of the rs2736098 genotypes was significantly associated with TNM stage, tumor differentiation, tumor size and lymph node metastasis (P < 0.05). The frequencies of hTERT gene rs2853669 polymorphism were not significantly different between CRC patients and healthy controls. Logistic regression analysis indicated that both body mass index (BMI) and hTERT gene rs2736098 polymorphism remained significantly correlated with CRC susceptibility. The frequencies of hTERT gene rs2853669 polymorphism did not differ significantly between CRC patients and control group (P > 0.05). The hTERT gene rs2736098 polymorphism was correlated with CRC risk in the Chinese Han population, and the GA genotype was a risk element for the onset of CRC.
期刊介绍:
Our mission is to publish peer-reviewed papers in all branches of medical sciences including basic medicine, social medicine, clinical medicine, nursing sciences and disaster-prevention science, and to present new information of exceptional novelty, importance and interest to a broad readership of the TJEM.
The TJEM is open to original articles in all branches of medical sciences from authors throughout the world. The TJEM also covers the fields of disaster-prevention science, including earthquake archeology. Case reports, which advance significantly our knowledge on medical sciences or practice, are also accepted. Review articles, Letters to the Editor, Commentary, and News and Views will also be considered. In particular, the TJEM welcomes full papers requiring prompt publication.
