RNA sequencing to detect the differentially expressed genes in AngII infused mice after Ethoxysanguinarine, Baicalin, Gastrodin or Valsartan treatment

The goals of this study is to identify the differential expressed genes in cardiac tissue of C57BL/6 mice with or without Angiotensin II (AngII) treatment, and compare the differential expressed genes in the cardiac tissue of Ang II infused C57BL/6 mice after Ethoxysanguinarine (ETH), Baicalin (BAI), Gastrodin (GAS) or valsartan (VAL) treatment. Briefly, the mice (n=30) were randomly divided into 6 groups: control, AngII, AngII + ETH, AngII + BAI, AngII + GAS and AngII + VAL groups (n=5 for each group). Mice in Control and AngII groups were infused with saline and 500 ng/kg/min of AngII respectively, and orally administrated with saline; the mice in AngII + ETH, AngII + BAI and AngII + GAS groups were infused with AngII (500 ng/kg/min) and orally administrated with 5 mg/kg /day of ETH, BAI or GAS daily for total 4 weeks. The mice in AngII + VAL group were infused with AngII (500 ng/kg/min) and orally administrated with 10.4mg/kg /day of VAL. Then the cardiac tissues were used to identify differentially expressed genes among different groups. Overall design: RNA sequencing was performed with cardiac tissue of mice in 6 groups: control, AngII, AngII + ETH, AngII + BAI, AngII + GAS and AngII + VAL groups (n=5 for each group) to identify the differently expressed genes and related pathway.
