The study was aimed to assess the effect of Klotho gene and sinoatrial node pacing channel gene (HCN4 and HCN2) for studying sick sinus syndrome, with Klotho gene under the interference of Plasmid-mediated short hairpin RNA. Twenty-five C57BL/6J mice were divided into four groups, i. e, plasmid shRNA 24h group, plasmid shRNA 12h group, sodium chloride 24h group and sodium chloride 12h group. Plasmid shRNA 50microL (1microg/microL) and sodium chloride 50microl were respectively injected according to mice vena caudalis into those in plasmid shRNA group and sodium chloride group. After 12h or 24h respectively, all mice were executed and their sinoatrial node tissues were cut. The mRNA of Klotho, HCN4 and HCN2 gene were detected by RT-PCR. The results of RT-PCR showed that Klotho, HCN4 and HCN2 mRNA levels were lower compared with those in sodium chloride 12h group after 12h interference interval. The results indicated that there might be the a certain relationship between Klotho gene and sinoatrial node pacing channel gene.
