Recent studies have demonstrated that paclitaxel might inhibit renal fibrosis. However, the underlying molecular mechanism remains unclear. In this study, we hypothesized that low-dose paclitaxel may block the STAT3 (signal transducer and activator of transcription 3) signaling to attenuate fibrosis in a mouse model with unilateral ureteral obstruction. Both NRK-49F cells and mice with unilater...

Background:Otitis media is an inflammation of part or all the mucoperiosteal lining middle ear cleft. It can be acute, subacute and chronic otitis infection. Septal deviation has got many unwanted changes such as: nasal obstruction, mucosal changes. Methodology:A descriptive clinical study, carried out on adult patients consulting ENT department at medical city. Those have a unilateral suppurat...

Renal responses to the activation of renal sensory receptors were examined in rats after release of 24-h unilateral ureteral obstruction of the left kidney. The integrity of the renorenal reflex was examined in both 24-h unilateral ureteral obstruction-treated (UUO) and sham-operated (Sham) rats. Increased ipsilateral afferent renal nerve activity (ARNA) and reflexly decreased efferent renal ne...

Hepatocyte growth factor (HGF) is a renotropic protein that elicits antifibrogenic activity by preventing the activation of matrix-producing myofibroblast cells in animal models of chronic renal diseases. However, whether a delayed administration of HGF can still attenuate renal fibrosis remains uncertain. In this study, we examined the therapeutic potential of exogenous HGF on an established r...

Renal interstitial fibrosis is a common pathway for the progression of chronic kidney disease (CKD) to end-stage renal disease. Renalase, acting as a signaling molecule, has been reported to have cardiovascular and renal protective effects. However, its role in renal fibrosis remains unknown. In this study, we evaluated the therapeutic efficacy of renalase in rats with complete unilateral urete...

Activation of renal interstitial fibroblasts is critically involved in the development of tubulointerstitial fibrosis in chronic kidney diseases. In this study, we investigated the effect of trichostatin A (TSA), a specific histone deacetylase (HDAC) inhibitor, on the activation of renal interstitial fibroblasts in a rat renal interstitial fibroblast line (NRK-49F) and the development of renal ...

Renal fibrosis is the final common pathway of a wide variety of chronic kidney diseases. Myofibroblast formation via the differentiation of from tissue-resident fibroblasts and bone marrow-derived mesenchymal stem cells (MSCs), and epithelial-to-mesenchymal transition (EMT) is known to play a pivotal role in the development of renal fibrosis. However, the detailed mechanisms underlying this dis...

Renal fibrosis plays an important role in the onset and progression of chronic kidney diseases (CKD). Although several mechanisms underlying renal fibrosis and candidate drugs for its treatment have been identified, the effect of iron chelator on renal fibrosis remains unclear. In the present study, we examined the effect of an iron chelator, deferoxamine (DFO), on renal fibrosis in mice with s...

Previously, we showed that neonatal induced chronic partial unilateral ureteral obstruction (PUUO) of the multipapillary pig kidney decreased glomerular filtration rate (GFR) of the obstructed kidney. We hypothesized that ANG II and nitric oxide (NO) are important for the changes in renal function and in the present study we examined the effects of chronic AT1 receptor blockade using CV-11974 (...
