Abstract:
The aim of the studies was to investigate klotho gene effect on the endothelial dysfunction of spontaneously hypertensive rats (SHR). In this study, ten SHR and ten normal Wistar rats, all 22 week old, were prepared. After given intraperitoneal anesthesia, the rats' brains, lungs, hearts, kidneys and aortas were removed. The identification was made by means of real-time polymerase chain reaction (Real-time PCR) and Enzyme-Linked Immunosorbent Assay (ELISA). Compared with the normal group, the klotho mRNA and protein in SHR were less than those in the control group with normal corresponding values, while Endothelin-1 (ET-1)'s mRNA and protein were more than those of normal group. The analysis of the correlation of mRNA and protein in heart and aorta revealed that klotho gene was negatively correlated to ET-1. The results showed that klotho significantly decreased in SHR, which might be influenced by hypertension-induced damage on the endothelial function.
