Common single-nucleotide polymorphisms (SNPs) in microRNAs (miRs) have been shown to be associated with susceptibility to several types of human cancer. However, the association of miR-933 rs79402775 with gastric cancer (GC) has not been explored.
The association between rs79402775 in miR- 933 and the risk of GC was explored in Chinese population based on MassARRAY technology. A total 374 GC patients and 999 cancer-free controls were enrolled in this study.
Compared with the wild-type GG, GA genotype was associated with a significantly decreased risk of GC (OR=0.542, 95% CI=0.299-0.983, p=0.044) in female subjects. Moreover, the variant was also associated with the expression of alpha fetoprotein (AFP) and carcinoembryonic antigen (CEA).
miR-933(rs79402775) may contribute to decreased susceptibility to GC and this SNP could be developed as a biomarker for GC prognosis.
微小RNA（miR）中的常见单核苷酸多态性（SNP）已被证明与多种人类癌症的易感性相关。然而，miR-933 rs79402775与胃癌（GC）的关联尚未得到探索。
基于MassARRAY技术，在中国人群中探索miR-933中rs79402775与GC风险之间的关联。本研究共纳入374例GC患者和999例无癌对照。
在女性受试者中，与野生型GG相比，GA基因型与GC风险显著降低相关（OR = 0.542，95% CI = 0.299 - 0.983，p = 0.044）。此外，该变异还与甲胎蛋白（AFP）和癌胚抗原（CEA）的表达相关。
miR-933（rs79402775）可能有助于降低GC易感性，并且该SNP可开发为GC预后的生物标志物。
