Project description:This study was aimed to investigate the role and underlying mechanism of TRPM2 in cisplatin nephrotoxicity. Cisplatin-induced acute kidney injury (AKI) model was established in WT and TRPM2-KO mice. The transcriptome profiling of the kidneys of WT and TRPM2-KO mice treated with cisplatin was compared to find differentially expressed gene which may be related to TRPM2 on cisplatin nephrotoxicity.

Project description:We investigated an acute kidney injury (AKI) model in rats induced by cisplatin (Cp) administration. The cisplatin is widely used since its biochemical and histopathological characteristics are representative of drug-induced AKI in humans. Male Wistar rats were dosed once ip with 0, 1 and 3 mg/kg cisplatin. Tubular necorsis was observed histopathologically in all treated rats and war recovery on day 26. Gene expression profiling of the kidney cortex with microarrays 3, 5, 8, and 26 days after single administration of 3mg/kg Cp revealed a major profile pattern characterized by maximally increased and decreased mRNA levels on day 8, with clear changes already found 3 days after treatment for about half of the mRNAs. The mRNA expression pattern after administration of 1mg/kg Cp was overall similar, yet with a dose-dependent smaller fold-change. In summary we found 274 mRNAs showing significantly altered levels in the kidney of which 162 were increased and 112 decreased, respectively. Functional interpretation of the proteins encoded by these mRNAs revealed induction of a DNA damage response likely caused by the known molecular activity of Cp as DNA alkylating agent. Increased mRNAs associated with apoptosis (encoded by the corresponding genes like B-cell lymphoma 3-encoded protein, Bcl3; mouse double minute 2 homolog, Mdm2; p21/WAF1 also known as cyclin-dependent kinase inhibitor 1), cell cycle regulation (encoded by the corresponding genes like Cyclin-G1, Ccng1; B-cell translocation gene 2, Btg2) and stress response may have partly been induced by the DNA damage, but also by the kidney damage associated with Cp administration. Increased levels of mRNAs indicating regeneration (encoded by the corresponding genes like SPARC- related modular calcium-binding protein 2, Smoc2; Tenascin C, Tnc) and decreased levels of mRNAs coding for proteins related to kidney function, indicating dedifferentiation, are likely related to the observed kidney injury. Male Han Wistar rats (8 weeks old) were randomly grouped (n = 6) and dosed once i.p. with 0, 1 or 3 mg/kg body weight cis-diamminedichloroplatinum (II) (cisplatin; Sigma Aldrich, Germany) diluted in 0.9% saline. For histopathological examination of the kidney and for kidney RNA isolation animals were euthanized on days 3, 5, 8 and 26.

Project description:The availability of mesenchymal stem cells in kidney injury repair has been demonstrated. However, the underlying molecular mechanism remains not well understood. Herein, we profiled the altered microRNAs in renal tissiues from cisplatin-induced acute kidney injury (AKI) rats administrated with or without rat bone marrow mesenchymal stem cells, normal kidneys as control. Sprague Dawley rats were administrated with PBS by caudal vein after 24h peritoneal injection of 6mg/mg cisplatin, short for g2. 1×106 MSCs were injected to rats after 24h peritoneal injection of cisplatin, short for g3. Kidneys from healthey rats were used as control, short for g1. Renal tissues were collected at day 5 after treatment. There were 44 micorRNAs changed with significance between g2 and g3, among which 36 microRNAs upregulated and 8 microRNAs downregulated.

Project description:Farnesoid X receptor (FXR, also known as NR1H4) is crucial to nephroprotective in several kinds of kidney diseases, including obesity, diabetes, aging, acute kidney injury and chronic kidney disease. FXR plays a key role in maintaining cholesterol and bile acid levels and is highly expressed in the liver, intestine and kidneys. In kidney diseases, it is reported that FXR has anti-lipogenic, anti‐inflammatory, antifibrotic, and antioxidant functions. Here, using genomics analysis, we investigated whether FXR attenuates cisplatin-induced AKI through the regulation of ferroptosis. The increased blood urea nitrogen, serum creatinine and ferroptotic responses in cisplatin-induced AKI mice were attenuated by treatment with FXR agonist, GW4064, while those were exacerbated in FXR knockout mice. Using RNA-sequencing analysis, we found novel target genes for FXR associated with ferroptosis. FXR agonist treatment increases lipid and glutathione metabolic gene expression and decreases cell death genes expression. This study identifies transcriptional regulation of ferroptosis by FXR as a potential therapeutic target for cisplatin-induced AKI.

Project description:Interstitial renal inflammation contributes to the transition from acute kidney injury (AKI) to chronic kidney disease (CKD). Recently, protein lactylation modification has emerged as a novel mechanism mediating chronic organ damage. We investigated lactylated protein profiles and the role of protein lactylation during AKI progression. Severe and moderate AKI mouse models were constructed by bilateral renal ischemia for 35 and 25 min respectively. The lactylation enhancer and inhibitors were used to verify the effect of protein lactylation. Lactylated proteomics was used to detect lactylated protein changes in kidneys, and the lactylated proteins related to kidney injury were screened for verification. We observed significantly higher lactate and protein lactylation levels in the severe than in the moderate AKI model 1–28 days post-injury. Inhibition of protein lactylation protected against renal interstitial fibrosis. In vitro and in vivo experiments demonstrated that protein lactylation activated Nod-like receptor protein 3 (NLRP3) inflammasomes, promoting the AKI–CKD transition. Comprehensive lactylome profiling of severe AKI models revealed a role for lactylated proteins in metabolic pathways, primarily the tricarboxylic acid (TCA) cycle where the rate-limiting enzyme, citrate synthase (CS), exhibited significantly elevated lactylation levels 3–7 days post-AKI induction; K370 was the most significant lysine residue. In vitro, following hypoxia/reoxygenation, the modified/lactylated K370T group significantly decreased CS activity and mitochondrial function. Furthermore, CS-K370 lactylation activated the NLRP3 inflammasome. Lactylation of CS promotes the AKI–CKD transition through NLRP3 inflammasome activation. Inhibition of CS lactylation shows therapeutic potential for preventing this transition.
