Aim:Recent information indicates that pentoxifylline (PTX) has the ability to suppress inflammation and profibrotic cell proliferation. In this study, we investigated the effect of PTX on tubulointerstitial fibrosis and the expression of vascular endothelial growth factor (VEGF) in a rat model of obstructive nephropathy.Methods:Wistar rats with left(More)
OBJECTIVE To examine the expression of vascular endothelial growth factor (VEGF) and its receptors (VEGFR1, VEGFR2) in transdifferentiated human proximal tubular epithelial (HK-2) cell induced by transforming growth factor beta1 (TGFbeta1). METHODS The transdifferentiation of HK-2 cells was detected by evaluation of expression of alpha-SMA by(More)
Aim:Lipolysis in fat tissue plays an important role in the development of metabolic disturbances, a characteristic feature of chronic kidney disease (CKD). In the present study, we tested the hypothesis that the inhibition of endoplasmic reticulum (ER) stress could alleviate lipolysis in white adipose tissue in a rat model of CKD.Methods:A rat model of CKD(More)
Aim:Vascular endothelial growth factor (VEGF) has been shown to be a survival factor for renal tubular epithelial cells. In the present study, we investigated whether administration of VEGF ameliorates tubulointerstitial fibrosis in a mouse model of unilateral ureteral obstruction (UUO).Methods:Thirty-six male CD-1 mice were randomly divided into three(More)
OBJECTIVE To examine the effect of Bone Morphogenetic protein-7 (BMP-7) on Monocyte chemoattractant protein-1 (MCP-1) induced epithelial-myofibroblast transition (EMT) in cultured renal proximal tubular cells (HK-2) and the relationship between TGF-beta1-smad 3 expressions and MCP-1 induced EMT. METHODS The cultured HK-2 cells were divided into six(More)
OBJECTIVE To observe the effect of bone morphogenetic protein-7 (BMP-7) on the transdifferentiation of cultured human tubular epithelial cell (HKC) induced by TGF-beta1 and to elucidate its possible mechanism. METHODS The cultured HKC cells were divided into 5 groups: serum-free group (negative control); single TGF-beta1 treated group (positive control);(More)
OBJECTIVE To determine the expressions of ryanodine receptor type 1 (RyR1) and Cav1.3 L-type calcium channel (Cav1.3) in the vaginal smooth muscle cells of castrated rats and investigate the correlation of RyR1 and Cav1.3 with estrogen in female sexual dysfunction. METHODS Forty female SD rats of 8 weeks were randomly divided into Groups A (2-week sham(More)
