Background: Hyperuricemia contributes to kidney injury, characterized by tubular injury with epithelial–mesenchymal transition (EMT). Wnt5a/Ror2 signaling drives EMT in many kidney pathologies. This study sought to evaluate the involvement of Wnt5a/Ror2 in hyperuricemia-induced EMT in kidney tubular injury.Methods: A hyperuricemia model was performed in male Swiss background mice (3 months old,...

results a significant decrease in apoptotic cells and increase in proliferative reaction were observed in the i/r + hbo group compared to the i/r group. conclusions we demonstrated that hbo suppressed apoptosis, which caused inflammation after renal i/r, and promoted tubular cell regeneration. hbo has protective effects against aki caused by renal i/r through the inhibition of apoptosis. materi...

Background and Objective: Increment in cancer prevalence and subsequent need for chemotherapy leads to distinct kidney-related diseases such as acute kidney injury (AKI). Cisplatin is a common chemotherapeutic agent that has been used in many cancers; however, it can damage renal cells. Capparis spinosa is an important therapeutic plant in Persian medicine that encompasses high amounts of bioac...

objective(s): repaglinide (rg) is an antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus. it has a good safety and efficacy profile in diabetic patients with complications in renal impairment and is an appropriate treatment choice, even for individuals with more severe degrees of renal malfunctions. the aim of the present study was to examine the protective...

Delayed graft function (DGF) is a frequent complication of renal transplantation, particularly in the setting of transplantation of kidneys derived from deceased donors and expanded-criteria donors. DGF results from tubular epithelial cell injury and has immediate and long term consequences. These include requirement for post-transplantation dialysis, increased incidence of acute rejection, and...

TGFβ signaling plays a central role in the development of acute and chronic kidney diseases. Previous in vivo studies involved systemic alteration of TGFβ signaling, however, limiting conclusions about the direct role of TGFβ in tubular cell injury. Here, we generated a double transgenic mouse that inducibly expresses a ligand-independent constitutively active TGFβ receptor type 1 (TβR1) kinase...

We previously demonstrated that renal peptidyl arginine deiminase-4 (PAD4) is induced after renal ischemia and reperfusion (I/R) injury and exacerbates acute kidney injury (AKI) by increasing the renal tubular inflammatory response. Here, we tested whether genetic ablation of PAD4 attenuates renal injury and inflammation after I/R in mice. After renal I/R, PAD4 wild-type mice develop severe AKI...

Reactive oxygen species (ROS) have been demonstrated to contribute to HIV-induced tubular cell injury. We hypothesized that HIV-induced ROS generation may be causing tubular cell injury through downregulation of vitamin D receptor (VDR) and associated downstream effects. In the present study, HIV not only downregulated tubular cell VDR expression but also inflicted DNA injury. On the other hand...

acute renal damage mainly develops following toxic or ischemic insults and is defined as acute. these damages have largely been attributed to oxidative stress. recently much attention has been directed toward decreased renal tubular cell regeneration during tubular cell injury. antioxidants have recently been the focus of researchers and scientists for prevention and treatment of various oxidat...

Objective(s): The aim of this study was to evaluate the effects of ground black seeds on renal tubular cell apoptosis following ischemia/reperfusion (I/R) injury in rats. Materials and Methods: Forty male Wistar rats were randomly allocated into 5 equal groups including Sham, I/R model and three I/R+ black seeds (5, 10 and 20%)-treated groups. I/R groups’ kidneys were subjected to 60 min of isc...
