Project description:To elucidate the function of PRDM16 in high glucouse environment , we performed RNA-seq on HPC cells transfected with negative control(NC) or PRDM16 overexpressing lenti-virus when treated with high glucouse .We then performed gene expression profiling analysis using data obtained from RNA-seq above.
Project description:Group 1 -- WT or PRDM16-KO ex vivo murine MLL-AF9 cells, and PRDM16-KO AF9 cells overexpressing either f-PRDM16 or s-PRDM16. Group 2 -- WT or total PRDM16-KO murine HSCs isolated from adult BM. Group 3 -- WT or total PRDM16-KO murine HSCs isolated from fetal liver. Group 4 -- WT or f-PRDM16-KO murine HSCs (expressing s-PRDM16 only) isolated from fetal liver.
Project description:Embryonic neocortical cells were isolated from E14.5 WT mice, followed by TrypLE Express treatment and trituration to generate a single-cell suspension. Plasmid DNA was introduced into primary neocortical cells using Neon Transfection System. Next, neocortical neurospheres were cultured in serum-free media containing, then control and Prdm16-overexpressing cells were corrected after GFP sorting of 1 day cultures. We found that marked upregulation of modulators of mitochondrial metabolism and ROS balance in Prdm16 GOF cells
Project description:Genome wide DNA methylation profiling of control (vector-transfected) and KLF4-overexpressing human podocytes (parental cell line: Saleem et al. JASN 13:630, 2002). The Illumina HumanMethylation450 Beadchip was used to obtain DNA methylation profiles. Bisulphite converted DNA samples from control (vector-transfected, n=1) and KLF4-overexpressing human podocytes (n=1) were hybridised to the Illumina HumanMethylation450 Beadchip and DNA methylation was compared.
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: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:Genome wide DNA methylation profiling of control (vector-transfected) and KLF4-overexpressing human podocytes (parental cell line: Saleem et al. JASN 13:630, 2002). The Illumina HumanMethylation450 Beadchip was used to obtain DNA methylation profiles.
Project description:To investigate podocyte gene expression and promoter methylation affected by KLF4, we examine about whole genome expression profiles using Agilent microarray and its correlation with promoter methylation profiles using Illumina DNA methylation array (GSE41689) as shown in supplementary data. Genome wide expression profiling of control (vector-transfected n=1) and KLF4-overexpressing (n=1) human podocytes (parental cell line: Saleem et al. JASN 13:630, 2002) and DNA methylation profile of promoter regions were shown.
Project description:Analysis of DZNep-induced gene expression changes in cultured podocytes. The hypothesis tested in the present study was that DZnep ultimately augments Txnip expression, increasing oxidative stress in podocytes. These results provide important information on the response of podocytes to histone methyltransferase inhibition and a possible mechanism for DZNep action in podocytes. Total RNA obtained from cultured podocytes subjected to 48 hours in vitro, with or without DZNep.
