Project description:Podocyte dysfunction is considered as the main contributor to the development and progression of diabetic kidney disease(DKD).High glucose(HG)or advanced glycation end products (AGEs) can lead to podocyte dysfunction.To explore the the molecular mechanism of podocyte dysfunction, we screened the mRNA expression profiles of podocytes treated with HG(50mmol/L)and AGEs(400µg/mL) through transcriptomics.

Project description:In diabetic nephropathy (DN), glomerular endothelial cells (GECs) and podocytes undergo pathological alterations, which are influenced by metabolic changes characteristic of diabetes, including hyperglycaemia (HG) and elevated methylglyoxal (MGO) levels. However, it remains insufficiently understood what effects these metabolic factors have on GEC and podocytes and to what extent the interactions between the two cell types can modulate these effects. To address these questions, we established a co-culture system in which GECs and podocytes were grown together in close proximity, and assessed transcriptional changes in each cell type after exposure to HG and MGO. We found that HG and MGO had distinct effects on gene expression and that the effect of each treatment was markedly different between GECs and podocytes. HG treatment led to upregulation of “immediate early response” genes, particularly those of the EGR family, as well as genes involved in inflammatory responses (in GECs) or DNA replication/cell cycle (in podocytes). Interestingly, both HG and MGO led to downregulation of genes related to extracellular matrix organisation in podocytes. Crucially, the transcriptional responses of GECs and podocytes were dependent on their interaction with each other, as many of the prominently regulated genes in co-culture of the two cell types were not significantly changed when monocultures of the cells were exposed to the same stimuli. Finally, the changes in the expression of selected genes were validated in BTBR ob/ob mice, an established model of DN. This work highlights the molecular alterations in GECs and podocytes in response to the key diabetic metabolic triggers HG and MGO, as well as the central role of GEC-podocyte crosstalk in governing these responses.

Project description:We report the high-throughput sequencing results in mammalian cell lines. Neutrophils were induced by HL-60 with 1umol/L ATRA(all-trans retinoid acid ) stimulation for 7days. Neutrophils were then stimulated with 0.05ug/mL AGEs，30mmol/L D-glucose, AGEs+D-glucose and 0.05ug/mL BSA (control) for 24-hours, then mRNA profiles were extracted and tested using Illumina Hiseq 4000. This study provides a prospective work for the influence of AGEs and high-glucose in human neutrophils.

Project description:Extracellular vesicles were isolated from the cell culture supernatants of podocytes under high glucose(HG), normal glucose(NG) and iso-osmolality stimulation (three replicates/group). miRNA sequencing was performed to identify differentially expressed miRNAs in podocyte-derived extracellular vesicles. After sequencing, A total of 1915 miRNAs were annotated from all samples . A comparison of the HG and NG groups showed that 11 miRNAs were differentially expressed (4 for up-regulated and 7 for down-regulated,|log2(fold change)| > 1, p-value < 0.05), while a comparison of the HG and iso-osmolality groups showed that 18 miRNAs were differentially expressed (1 for up-regulated and 17 for down-regulated, |log2(fold change)| > 1, p-value < 0.05). This study provides the results of miRNA alteration in podocytes extracellular vesicles under HG stimulation.

Project description:The gene expression profile of human iPSC derived podocytes were analyzed by utilizing NEPHS1-GFP knock-in human iPS cell line. The induced podocytes shows characteristic gene expression pattern that overlap with those of mouse and human podocytes in vivo. Kidney tissue was induced from human iPSC by our originally established protocol. NEPHS1-GPF knock-in human iPSC was used to isolate podocytes from induced kidney tissues. To identify the molecules which are specifically expressed in induced podocytes, NEPHS1-GFP positive and negative fractions were sorted by FACS and compared. RNA was isolated from cells and the gene expression profiles were determined by microarrays.
