چکیده
OBJECTIVE To investigate whether rs12731181 (A→G) interrupted miR-590-3p-mediated suppression of the prostaglandin F2α receptor (FP) and whether it is associated with essential hypertension in the Chinese population. APPROACH AND RESULTS We found that miR-590-3p regulates human FP gene expression by binding to its 3'-untranslated region. rs12731181 (A→G) altered the binding affinity between miR-590-3p and its FP 3'-untranslated region target, thus reducing the suppression of FP expression, which, in turn, enhanced FP receptor-mediated contractility of vascular smooth muscle cells. Overexpression of FP augmented vascular tone and elevated blood pressure in mice. An association study was performed to analyze the relationship between the FP gene and essential hypertension in the Han Chinese population. The results indicated that the rs12731181 G allele was associated with susceptibility to essential hypertension. Carriers of the AG genotype exhibited significantly higher blood pressure than those of the AA genotype. FP gene expression was significantly higher in human peripheral leukocytes from individuals with the AG genotype than that in leukocytes from individuals with the AA genotype. CONCLUSIONS rs12731181 in the seed region of the miR-590-3p target site is associated with increased risk of essential hypertension and represents a new paradigm for FP involvement in blood pressure regulation.

MicroRNAs (miRNAs) have emerged as essential gene expression regulators associated with human diseases such as colorectal cancer (CRC). The purpose of this study was to evaluate the expression of miR-330-3p and its target gene BMI1 in tissue samples of patients with CRC, polyp, and healthy adjacent tissue samples and their association with clinicopathological and demographic factors such as age...
متن کاملCommon miR-590 Variant rs6971711 Present Only in African Americans Reduces miR-590 Biogenesis
MicroRNAs (miRNAs) are recognized as important regulators of cardiac development, hypertrophy and fibrosis. Recent studies have demonstrated that genetic variations which cause alterations in miRNA:target interactions can lead to disease. We hypothesized that genetic variations in miRNAs that regulate cardiac hypertrophy/fibrosis might be involved in generation of the cardiac phenotype in patie...
متن کاملA Functional Variant at miR-520a Binding Site in PIK3CA Alters Susceptibility to Colorectal Cancer in a Chinese Han Population
An increasing body of evidence has indicated that polymorphisms in the miRNA binding site of target gene can alter the ability of miRNAs to bind their target genes and modulate the risk of cancer. We aimed to investigate the association between a miR-520a binding site polymorphism rs141178472 in the PIK3CA 3'-UTR and the risk of colorectal cancer (CRC) in a Chinese Han population. The polymorph...

Background: Endometriosis is one of the most common benign gynecological diseases which is characterized by endometriallike tissue growing outside the uterine cavity. Although the pathology of endometriosis remains unknown, the genetic predisposition plays an apparent role. Several genes have been contributed to endometriosis, but it seems KRAS has a crucial role, because its activation results...
