摘要: Cold temperatures are associated with increased prevalence of hypertension. exposure increases endothelin-1 (ET1) production. The purpose this study is to determine whether upregulation ET1 contributes cold-induced hypertension (CIH). In vivo RNAi silencing the gene was achieved by adeno-associated virus 2 (AAV2) delivery short-hairpin small interfering RNA (ET1-shRNA). Four groups male rats were used. Three given AAV.ET1-shRNA, AAV.SC-shRNA (scrambled shRNA), and phosphate-buffered saline (PBS), respectively, before a moderately cold environment (6.7 ± 2°C), while last group PBS kept at room temperature (warm, 24 ± 2°C) served as control. We found that systolic blood pressure PBS-treated SC-shRNA–treated significantly within weeks cold, reached peak level (145 ± 4.8 mmHg) 6 weeks, remained elevated thereafter. By contrast, ET1-shRNA-treated did n...
