Abstract

Genetic variants in several long noncoding RNA genes have been implicated in the occurrence and development of colorectal cancer (CRC). In this study, we explored the association between HAND2-AS1 gene rs2276941 polymorphism and the risk and clinical stage of CRC. A direct sequencing method was used to detect the rs2276941 polymorphism in 576 CRC patients and 864 healthy individuals. Real-time quantitative PCR technology was used to explore the expression of HAND2-AS1 and hsa-miR-1275 in colorectal tissues with different rs2276941 genotypes. Dual-luciferase reporter assay was used to assess the function of the rs2276941 polymorphism. We found that the rs2276941 polymorphism was associated with a decreased risk of CRC (TT vs. CC, OR = 0.38, 95% CI = 0.16-0.89, p = 0.03; TT vs. [CC+CT], OR = 0.40, 95% CI = 0.17-0.94, p = 0.03). Furthermore, a significant negative correlation was observed between the expression of HAND2-AS1 and hsa-miR-1275 in colorectal tissues with rs2276941 TT genotype. Functional experimental results showed that the rs2276941 T allele might promote the binding of HAND2-AS1 to hsa-miR-1275. The current study results suggested that HAND2-AS1 gene rs2276941 polymorphism affecting the binding of hsa-miR-1275 was associated with CRC risk and might serve as a CRC susceptibility biomarker.

影响hsa-miR-1275结合的HAND2-AS1 rs2276941多态性与结直肠癌风险相关
一些长链非编码RNA基因的遗传变异与结直肠癌(CRC)的发生和发展有关。在本研究中,我们探讨了HAND2-AS1基因rs2276941多态性与结直肠癌风险和临床分期的关系。采用直接测序方法检测576例结直肠癌患者和864例健康人rs2276941基因多态性。采用实时定量PCR技术检测不同rs2276941基因型结直肠组织中HAND2-AS1和hsa-miR-1275的表达情况。采用双荧光素酶报告基因法评估rs2276941多态性的功能。我们发现rs2276941多态性与CRC风险降低相关(TT vs. CC, OR = 0.38, 95% CI = 0.16-0.89, p = 0.03;TT与(CC + CT),或= 0.40,95% CI -0.94 = 0.17, p = 0.03)。此外,在rs2276941 TT基因型的结直肠组织中,HAND2-AS1和hsa-miR-1275的表达呈显著负相关。功能实验结果显示,rs2276941 T等位基因可能促进HAND2-AS1与hsa-miR-1275的结合。目前的研究结果提示,影响hsa-miR-1275结合的HAND2-AS1基因rs2276941多态性与结直肠癌风险相关,可能作为结直肠癌易感性生物标志物。
