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:To clarify the effects of cisplatin (cis-diamminedichloroplatinum II, CDDP) on the gene expression profiles in renal proximal tubules, microarray analyses were carried out using total RNA samples isolated from microdissected proximal tubules and whole kidneys. The molecular events underlying acute kidney injury (AKI) in the proximal tubules of rats with cisplatin-induced nephrotoxicity were successfully clarified with 17,000 transcripts. Renal proximal tubules were isolated under microscopy, and transcriptome data were collected with Rat Genome Survey Microarray® (Applied Biosystems)

Project description:NRK cells were exposed to serum-free, 10% FBS (control), 10% serum sampled from rats 24 hours after sham surgery (no kidney injury control), or 10% serum sampled from rats 24 hours after I/R AKI surgery (kidney injury serum). After 48 hours of exposure to serum, the NRK cells were harvested and processed for Agilent microarray We previously conducted a Phase I Clinical Trial in which Mesenchymal Stem/Stromal Cells (MSCs) were administered to patients at risk for developing acute kidney injury (AKI), and which suggested that MSC therapy is safe and effective in preventing both postoperative AKI and progression to CKD. It is well understood that AKI creates an internal environment that adversely affects not only the kidneys but also the function of distant organs and tissues. To study the consequences of the AKI environment on MSCs and renal cells, we developed an in vitro assay of exposing MSCs or cultured tubular cells (NRK Cells) to serum from animals that had AKI, or SHAM surgeries. Compared to SHAM sera, exposure of cells to AKI serum caused increased intra-cellular resazurin reduction, and activation of anti-oxidant genes,

Project description:Acute kidney injury and nephrotoxicity are important clinical side effects of cisplatin. Thus, the mechanisms of this disease, and potential treatment options are important to understand in their entity. Here, we analyzed the proteome of cisplatin induced acute kidney injury in a mouse model. Functionally we found that calorie restriction was able to completely blunt Cisplatin induced AKI, and hypoxia ameliorated cCisplatin induced AKI. To investigate the mechanism for this in high throughput, we performed label-free single-shot proteomic analyses of these kidneys.Acute kidney injury and nephrotoxicity are important clinical side effects of cisplatin.

Project description:Acute kidney injury (AKI) is characterized by a rapid reduction in renal function and glomerular filtration rate (GFR). The broadly used anti-cancer chemotherapeutic agent cisplatin often induces AKI as an adverse drug side effect. Therapies targeted at the reversal of AKI and its potential progression to chronic kidney disease or end-stage renal disease are currently insufficiently effective. Mesenchymal stromal cells (MSC) possess diverse immunomodulatory properties that confer upon them significant therapeutic potential for the treatment of diverse inflammatory disorders. Human dermal MSCs expressing ATP-Binding Cassette member B5 (ABCB5) have shown therapeutic efficacy in clinical trials in chronic skin wounds or recessive dystrophic epidermolysis bullosa. In preclinical studies, ABCB5+ MSCs have also been shown to reverse metabolic reprogramming in polycystic kidney cells, suggesting a capacity for this cell subset to also improve organ function in kidney diseases. Here, we aimed to explore the therapeutic capacity of ABCB5+ MSCs to improve renal function in a preclinical rat model of cisplatin-induced AKI. First, ABCB5+ MSCs suppressed cisplatin-induced apoptosis of human conditionally-immortalized proximal tubular epithelial cells in vitro. Second, ABCB5+ MSCs inhibited the proliferation of either human or rat peripheral blood mononuclear cells. Third, ABCB5+ MSCs decreased TNF-α secretion after LPS stimulation in both human and rat macrophages. Fourth, clinical-grade ABCB5+ MSCs grafted intravenously and intraperitoneally to a cisplatin-induced AKI murine model exerted modulatory effects on mRNA expression patterns towards an anti-inflammatory and pro-regenerative state despite an apparent lack of amelioration of renal damage at physiologic, metabolic, and histologic levels. Our results demonstrate anti-inflammatory and pro-regenerative effects of clinical grade ABCB5+ MSCs in vitro and in vivo and suggest potential therapeutic utility of this cell population for treatment or prevention of cisplatin chemotherapy-induced tissue toxicity.

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: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.
