摘要

Ischemic heart disease (IHD), stemming from coronary atherosclerosis, involves pathological processes in which chaperone proteins play an essential role. SERBP1 (Hero45), an RNA-binding protein, has recently been ascribed to the newly discovered class of Hero proteins with chaperone-like activity, making it particularly relevant in atherosclerosis-related diseases. In this study, 2164 subjects (836 IHD patients and 1328 controls) were genotyped for five common single nucleotide polymorphisms (SNPs) of SERBP1 using probe-based PCR. Here, we report that SNPs of SERBP1 are associated with reduced risk of left coronary artery atherosclerosis: rs4655707 (effect allele [EA] T, OR = 0.63, 95% CI 0.43–0.93, p = 0.02), (EA C, OR = 0.63, 95% CI 0.42–0.95, p = 0.02), rs12561767 (EA G, OR = 0.65, 95% CI 0.45–0.96, p = 0.03), rs6702742 (EA A, OR = 0.63, 95% CI 0.43–0.94, p = 0.02). Additionally, SERBP1 loci are linked to lower coronary artery stenosis (rs1058074), improved blood lipid profiles (rs1058074), and favorable blood coagulation parameters (rs4655707, rs6702742, rs1058074, rs12561767). Together, our study is the first to provide evidence that SERBP1 is involved in lipid metabolism and coagulation regulation, modulating IHD risk.
