LncRNA ANRIL Expression and ANRIL Gene Polymorphisms Contribute to the Risk of Ischemic Stroke in the Chinese Han Population.
The aim of the present study was to explore the role of lncRNA ANRIL in the pathogenesis of ischemic stroke (IS) and coronary artery disease (CAD) and to determine the association between ANRIL variants and the genetic susceptibility of IS and CAD in the Chinese Han population. A genetic association study including 550 IS patients, 550 CAD patients, and 550 healthy controls was conducted. The expression levels of lncRNA ANRIL, CDKN2A, and CDKN2B were detected using qRT-PCR. ⋯ In addition, we found a decreased lncRNA ANRIL expression in IS patients who carried the GG genotype of rs1333049 compared with IS patients who carried the CC or CG genotype (P = 0.041). In summary, we found that IS patients had an increased lncRNA ANRIL expression and a decreased CDKN2A expression compared with the controls, which might play an impellent role in pathological processes of IS. The ANRIL variants rs2383207 and rs1333049 were significantly associated with the risk of IS among males but not females in the Chinese Han population.
