Abstract Objective: To investigate the regulation of miR-221/222 on the expression and the relation with heart failure. Methods: The peripheral blood samples from male heart failure patients and healthy volunteers were collected and separated for blood cells and plasma, respectively. The genome DNA was extracted, amplified and sequenced for analyzing the distribution of SNP genotypes in the heart failure patients and healthy controls. The plasma miRNA was extracted and the expression of miR-221/222 was detected with a TaqMan assay. The plasma levels of miR-221/222 were analyzed according to the SNP genotypes in heart failure. Results: The distribution of SNP genotypes of rs2858059、rs2858060、rs2858061 and rs34678647 were all comparable between heart failure patients and healthy controls. The genotype of rs113054794 was only C/- in all of the study subjects. The rs182069485 and rs72808106 in the 3'UTR of p27 and DDIT4 encoding genes showed no polymorphism in all of the subjects. The plasma levels of miR-221 and miR-222 were increased in heart failure patients. More importantly, we observed that the T/- genotype of rs34678647 in miR-222 was related with the increase of plasma miR-222 in heart failure patients. Conclusion: Plasma miR-221/222 levels are increased in male heart failure patients. The genotype of rs34678647 is related with the plasma miR-222 levels in heart failure patients.
