miRNA expression profile in calcium oxalate (CaOx) nephrocalcinosis model.

Project description:Microarray analysis was used to assess the expression levels of miRNAs in six pairs of kidney tissues of calcium oxalate (CaOx) nephrocalcinosis mouse model and normal mouse kidney tissues.The animals used in the experiment were male 6-8 weeks old C57BL/6J mice. To establish a CaOx nephrocalcinosis mouse model, each mouse was intraperitoneally injected with saline or glyoxylate acid (Gly) (75 mg/kg/d, 200 μl) from day 1 to day 7. Animals were euthanized after 7 days, and kidney samples were collected at the time of euthanasia.

Gene expression profile of calcium oxalate nephrocalcinosis in wild type and NLPR3 knock out mice.

Project description:Microarray analysis was used to assess the expression levels of mRNAs in kidney tissues of calcium oxalate (CaOx) nephrocalcinosis mouse model and normal mouse kidney tissues.The animals used in the experiment were male 6-8 weeks old wild type and NLPR3 knock out C57BL/6J mice. To establish a CaOx nephrocalcinosis mouse model, each mouse was intraperitoneally injected with saline or glyoxylate acid (Gly) (75 mg/kg/d, 200 μl) from day 1 to day 7.

Analysis of altered LncRNA expression profiles in proximal renal tubular cells in response to calcium oxalate monohydrate crystal adhesion

Project description:The present study aims to assess the potential changes in LncRNAs of proximal renal cells in response to the adhesion of calcium oxalate monohydrate (COM) crystals. lncRNA microarray were applied to evaluate the expression of HK-2 cells exposed to COM crystal for 0 and 24 hours.

Analysis of microRNA expression profiles in exosomes of proximal renal tubular cells in response to oxalate crystal

Project description:The present study aims to compare the miRNA expression profiles in exosomes derived from HK-2 cells treated with 0, 1, 2 mM sodium oxalate, and to explore the roles of different exosomal-miRNAs in the regulation of calcium oxalate (CaOx) stones formation.

EZH2-mediated macrophage-to-myofibroblast transition contributes to calcium oxalate crystal-induced kidney fibrosis

Project description:Long-term nephrocalcinosis leads to kidney injury, fibrosis, and even chronic kidney disease (CKD). Reports have proved macrophages can transition into myofibroblasts(MMT), leading to collagen deposition and fibrosis in CKD. However, the effect of MMT in calcium oxalate (CaOx) crystal-induced kidney fibrosis remains unclear. This study demonstrated that histone methyltransferase EZH2-mediated MMT contributes to CaOx crystal-induced fibrosis. We identified abundant MMT cells by immunofluorescence and flow cytometry in kidney tissues of patients with CaOx-related CKD, CaOx nephrocalcinosis mouse model, and CaOx-treated RAW264.7 macrophage cells. A high level of MMT cell infiltration was associated with a decline in the glomerular filtration rate in CaOx nephrocalcinosis patients. Clodronate Liposomes-mediated macrophage depletion attenuates calcium oxalate crystal-induced fibrosis in mice. Subsequently, transcriptomic and single-cell sequencing revealed that EZH2 was highly expressed in kidneys with CaOx deposition, especially in macrophages. Further study demonstrated that EZH2 inducible knock-out or pharmacological inhibition by GSK-126 attenuated MMT and renal fibrosis in vivo and in vitro. Mechanistically, ChIP and transcriptomic sequencing showed that EZH2 inhibition reduced the enrichment of H3K27me3 on the DUSP23 gene promoter and elevated DUSP23 expression. The Co-IP and molecular docking analysis showed that DUSP23 mediated the dephosphorylation of pSMAD3 (S423/425), the key regulator of MMT. In addition, DUSP23 over-expression could alleviate SMAD3-mediated MMT. Thus, our study found that EZH2 promotes kidney fibrosis by meditating MMT via the DUSP23/SMAD3 pathway in nephrocalcinosis.

Expression factors for oxalate stimulation in HEK293T cells

Project description:parental HEK293T were challenged with 1064 µg/cm2 calcium oxalate monohydrate (COM) or sodium oxalate (NaOx) 4mM or vehicle for 24 hours and DNA microarray was performed. We observed and selected two-fold upregulation of laminin, beta 3 (LAMB3), early growth response 1 (EGR1), gremlin 1, DAN family BMP antagonist, Ca++-dependent secretion activator 2, Ras association domain family member 3, interleukin 33 and bone morphogenetic protein 8a , and two-fold down-regulation of interleukin 37 and intercellular adhesion molecule 1 in COM lord compared to vhicle.
