Triptolide, the primary active component of Tripterygium wilfordii Hook F, has various pharmacological activities but also a narrow therapeutic window. Cytochrome P450s are proposed to be responsible for the hydroxylation of triptolide in vitro and CYP3A induction by dexamethasone can increase the metabolism of triptolide and decrease the hepatotoxicity in(More)
Aristolochic acid (AA), a natural nephrotoxin and carcinogen, can induce a progressive tubulointerstitial nephropathy. However, the mechanism by which AA causes renal injury remains largely unknown. Here we reported that the mitochondrial permeability transition (MPT) plays an important role in the renal injury induced by aristolochic acid I (AAI). We found(More)
Emodin, an anthraquinone derived from a plant and fungi, has been reported to possess potential genotoxicity, but the mechanism is not entirely clear. Here, we report that emodin causes DNA double-strand breaks (DSBs) through stabilization of topoisomerase (Topo) II-DNA cleavage complexes and inhibition of ATP hydrolysis. In our study, emodin did not induce(More)
BACKGROUND Hyperphosphataemia in patients with advanced chronic kidney disease (CKD) is associated with adverse outcomes, including vascular calcification and higher mortality rates. While phosphate lowering is an integral aspect of CKD management, the efficacy and safety of phosphate binders in a contemporary cohort of Chinese haemodialysis patients (who(More)
BXSB mice spontaneously develop an autoimmune syndrome characterized by hypergammaglobulinemia, autoantibody production, and the development of fatal glomerulonephritis that closely resembles systemic lupus erythematosus (SLE) in humans. While blocking positive T cell co-stimulation has shown effectiveness in preventing the onset of murine lupus, deliberate(More)
Cyp2e1 plays an important role in chemically induced hepatocarcinogenesis. Resveratrol (REV) is known to prevent diethylnitrosamine (DEN)-induced hepatocarcinogenesis, but its effects on this process induced by DEN and 2-acetylaminofluorene (2-AAF) and the role of Cyp2e1 remain unclear. In this study, glutathione S-transferase placental form(More)
INTRODUCTION Few have tried to prove the effectiveness of mizoribine combined with losartan for adult IgA nephropathy patients in a randomized controlled trial. METHODS A multicenter, randomized, controlled, 12-month study was performed to evaluated the efficacy and safety of mizoribine combined with losartan for adult IgA nephropathy. Ninety-nine(More)
After comparing mortality and clinical signs in rats receiving different dexamethasone treatments, we investigated whether 0.5 mg/kg/d dexamethasone could delay pulmonary fibrosis induced by bleomycin and its time course (1, 3, 7, 14, 21 and 28 days). Tissue injury was assessed by apoptosis, lactate dehydrogenase (LDH) release, malondialdehyde content, and(More)
T cell activation is affected by both stimulatory and inhibitory co-signaling. MHC class II-expressing renal tubular epithelial cells (TEC) can function as APC for T cells. To study the influence of inhibitory ligands on TEC-mediated T cell activation, we examined the expression of programmed death ligand-1 (PD-L1) on human TEC line HK-2 cells, as well as(More)
Triptolide (TL) is an active component of Tripterygium wilfordii Hook. F which is used to treat autoimmune and inflammatory disease. However, a high incidence of adverse effects is often observed in clinic. Previously we have demonstrated that cytochrome P450s (CYPs) are involved in the metabolism of TL and low activity of hepatic P450 reductase aggravates(More)
