Expression of type Ⅰ transforming growth factor ? receptor in renal cortex of streptozotocin-induced type Ⅱ diabetic rats and the regulation of valsartan / 中国临床药理学与治疗学

AIM: To study the expression of type Ⅰtransforming growth factor ?(T?R-Ⅰ)in renal cortex in streptozotocin-induced type Ⅱ diabetic mellitus and the regulation of valsartan. METHODS: The rat models of type Ⅱ diabetic rats were made. At the end of the 20th weeks,the kidneys were taken out to measure the expression of T?R-ⅠmRNA by RT-PCR. RESULTS: The expression of T?R-ⅠmRNA in diabetic rats without any therapy ( 0.72? 0.14) was higher than that in control ( 0.26? 0.12) (P
