摘要


Hypertension is the most prevalent cardiovascular disease worldwide, but its genetic basis is poorly understood. Recently, genome-wide association studies identified 33 genetic loci that are associated with blood pressure. However, it has been difficult to determine whether these loci are causative owing to the lack of functional analyses. Of these 33 genome-wide association studies (GWAS) loci, the 4q21 locus, known as the fibroblast growth factor 5 (FGF5) locus, has been linked to blood pressure in Asians and Europeans. Using a mouse model, we aimed to identify a causative gene in the 4q21 locus, in which four genes (anthrax toxin receptor 2 (ANTXR2), PR domain-containing 8 (PRDM8), FGF5 and chromosome 4 open reading frame 22 (C4orf22)) were near the lead single-nucleotide polymorphism (rs16998073). Initially, we examined Fgf5 gene by measuring blood pressure in Fgf5-knockout mice. However, blood pressure did not differ between Fgf5 knockout and wild-type mice. Therefore, the other candidate genes were studied by in vivo small interfering RNA (siRNA) silencing in mice. Antxr2 siRNA was pretreated with polyethylenimine and injected into mouse tail veins, causing a significant decrease in Antxr2 mRNA by 22% in the heart. Moreover, blood pressure measured under anesthesia in Antxr2 siRNA-injected mice rose significantly compared with that of the controls. These results suggest that ANTXR2 is a causative gene in the human 4q21 GWAS-blood pressure locus. Additional functional studies of ANTXR2 in blood pressure may identify a novel genetic pathway, thus increasing our understanding of the etiology of essential hypertension.
