Alterations in gene expression of sarcoplasmic reticulum Ca~(2+)-ATPase and phospholamban detected by RNA array in spontaneously hypertensive rats / 中国病理生理杂志

ABSTRACT

AIM: To explore the relationship between the alteration in gene expression of sarcoplasmic reticulum Ca~(2+)-ATPase (SERCA) and phospholamban (PLB) in spontaneously hypertensive rats (SHR). METHODS: 294 samples of total RNA were obtained from the tissue of ventriculum , aortic smooth muscle, liver and kidney in SHR and normotensive rats (WKY). RNA array was used to determine the mRNA levels of SERCA and PLB. RESULTS: Compared with age-matched WKY rats, the systolic blood pressure increased higher in 6-week-old SHR (P
