Project description:Shotgun time-series proteomic analysis based on stable isotope dimethyl labeling and UHPLC-MS/MSC to relatively quantify the changes in protein expression of human proximal tubular HK-2 cells exposed to a diabetic-like microenvironment
Project description:We first performed miRNA analysis on SU-4 cells in suspension, and after 24 and 48 h of HK co-culture. To ensure that no HK cell contamination occurred, SU-4 cells in suspension and after co-culture were purified by CD19-positive magnetic selection, followed by total RNA isolation. Two-condition experiment, S4 vs. S4+HK cells. Biological replicates: 2 suspension controls, 2 co-cultured with HK cells, independently grown and harvested. One replicate per array.
Project description:Atlas Human Stress Arrays with 234 stress-related genes immobilised on nylon membranes (Clontech, UK) were used to identify the changes in mRNA expression in human proximal tubular HK-2 cells in response to HSA overload or AngII. Keywords: Stress response
Project description:To investigate the role of ACOX1, we knocked down ACOX1 by shRNA in HK-2 cell lines and detected differential genes. We then performed gene expression profiling analysis using data obtained from RNA-seq of 2 different cells.

Project description:Long noncoding RNAs (lncRNAs) have been proposed to be engaged in the pathogenesis of renal fibrosis. The current study aims to determine the role of lnc453774.1 in the development of renal fibrosis and its underlying mechanism.Transforming growth factor-β1 (TGF-β1)-induced cell model of renal fibrosis was constructed. RNA sequencing was performed to identify DEGs targeted by lnc453774.1 in TGF-β1-induced renal fibrosis. Dataset GSE23338 was adopted to identify DEGs in 48 h TGF-β1-stimuated human kidney epithelial cells, and these DEGs were interested with genes in the key module using a WGCNA to generate key genes associated with renal fibrosis. Miranda software was adopted to predict miRs that have targeting relationship with keys genes and lnc453774.1, and key genes that have targeting relationship with these miRs were regarded as important genes. A PPI network among lnc453774.1, important genes and reported genes related to autophagy, oxidative stress, and cell adhesion was constructed to select key target genes by lnc453774.1. Twenty key genes regulated by lnc453774.1 was yielded by intersecting genes in key module (turquoise) and dataset GSE23338. Fourteen miRs have targeting relationship with lnc453774.1 and key genes, and 8 important genes targeted by these 14 miRs were identified. FBN1, IGF1R and KLF7 were identified to be associated with autophagy, oxidative stress, and cell adhesion and were upregulated in the lnc453774.1-overexpressing in TGF-β1-induced cells. These results show FBN1, IGF1R and KLF7 serve as downstream targets of lnc453774.1 and protect against renal fibrosis by regulating autophagy, oxidative stress, and cell adhesion.
