Abstract

Background: Ischemic stroke (IS) is a commonly seen cerebrovascular disease which seriously endangers the health of middle age and old people. However, its etiology and pathogenesis have not yet fully comprehended. miR-30 gene is a novel gene which may be involved in IS. However, no studies have investigated the relationship between IS and the single-nucleotide polymorphisms (SNPs) of miR-30. Therefore, this study examined the relationship between miR-30 polymorphisms (rs2222722, rs1192037, rs10095483 and rs16827546) and the risk of IS.

Methods: Totally 248 IS patients and 230 age-, sex- and race-matched controls were involved in this study. Based on SNPscan technique, four polymorphisms (rs2222722, rs1192037, rs10095483 and rs16827546) were genotyped.

Results: There exists a significant association between rs2222722 polymorphism and the risk of IS according to analyses of genotypes, models and alleles (GA vs. GG: adjusted OR = 1.616, 95% CI: 0.943-2.768, P = 0. 081); (AA vs. GG: adjusted OR = 2.447, 95% CI: 1.233-4.858, P = 0.011); dominant model: adjusted (OR = 1.806, 95% CI, 1.082-3.016, P = 0.024); (G vs. A: adjusted OR = 1.492, 95% CI: 1.148-1.939, P = 0.003). Besides, miR-30a expression was significantly higher in patients undergoing IS relative to that in controls (P < 0.05).

Conclusions: To conclude, the rs2222722 polymorphism of the miR-30 gene shows a significant relationship to elevate the risk of IS in Chinese population.
