Project description:To identify the dysregulated lncRNA and mRNA expression in ARPE-19 cells underwent EMT, we established a TGF-β1 induced EMT model of ARPE-19 cells. ARPE-19 cells were treated with or without 10 ng/ml TGF-β1 for 48 h. Total RNA are extracted and subjected to microarray assay (Arraystar Human LncRNA Microarray V3.0)
Project description:The purpose of this study is to determine the changes in gene expression by a human retinal pigment epithelium (RPE) cell line (ARPE-19) in response to combination treatment of TGF and TNF, which induces phenotypic changes in vitro that mimic the EMT (Epithelial-to-Mesenchymal Transition). For this purpose, total RNA was extracted from TGF and TNF-treated ARPE-19 cells and differential gene expression between each time point (0, 1, 6, 16, 24, 42, and 60 hours) was determined using genechip arrays (Affymetrix, Human Genome U133). Experiment Overall Design: ARPE19 cell lines treated with TGF and TNF for 0, 1, 6, 16, 24, 42, and 60 hour. Each experiment were repeated three times. But 1 hour experiment was repeated two times.
Project description:Study the gene expression profiling of human retinal pigmented epithelium cell line ARPE-19 treated with or without human recombinant Cochlin protein for 24 hours.
Project description:To explore the key signaling pathways that might be affected by up-regulated HTRA1, we performed RNA-seq analysis on ARPE-19 cells infected with HTRA1 adenovirus and negative control adenovirus for 24 h. Compare with control groups, there were 2810 differentially expressed genes (log2 |fold change|> 1, log10 adjusted p-values < 0.05) were identified to be associated with distinct biological processes. 1053 genes were significantly upregulated and 1757 genes were significantly downregulated in ARPE-19 cells overexpressing HTRA1. The KEGG pathways analysis of up-regulated and down-regulated genes and ranking the enrichment pathways according to the corrected p-value. In the KEGG pathways analysis of up-regulated genes, the metabolic pathways ranked first with 84 genes involved. And in the KEGG pathways analysis of down-regulated genes, the metabolic pathways ranked third with 104 genes involved. These results revealed that up-regulated HTRA1 prominently disturbed the metabolic pathways in ARPE-19 cells.
Project description:We used microarrays to evaluate the effect of SRPIN803 on gene expression in ARPE-19 cells. ARPE-19 cells were treated with SRPIN803 (10 uM) or the negative control (0.1% DMSO) for 4 hours for Total RNA isolation and hybridization on Microarray.
Project description:To characterize the potential molecular pathway(s) affected by iron treatment and identify the one(s) responsible for C3 induction, we performed a whole genome microarray on untreated ARPE-19 cells and cells treated with 250 ?M FAC for 48h/2d. Gene expression was compared between untreated and FAC-treated ARPE-19 cells, with three biological replicates in each.
Project description:These data show that the genes that distinguish myofibroblasts from fibroblasts are myriad, and that some genes not traditionally associated with myofibroblast differentiation may serve as novel therapeutic targets for fibrosing disorders. Gene expression levels were assessed from total RNA on the Affymetrix U219 microarray. Here, we use transforming growth factor-β1 (TGF-β1) and prostaglandin E2 (PGE2), which has recently been shown to reverse myofibroblast differentiation, to investigate the transcriptomic changes that occur during TGF-β1-induced differentiation and PGE2-induced de-differentiation of myofibroblasts.

Project description:Fibrotic diseases have significant health impact and have been associated with differentiation of the resident fibroblasts into myofibroblasts. In particular, stiffened extracellular matrix and TGF-β1 in fibrotic lesions have been shown to promote pathogenic myofibroblast activation and progression of fibrosis in various tissues. To better understand the roles of mechanical and chemical cues on myofibroblast differentiation and how they may crosstalk, we cultured primary valvular interstitial cells (VICs) isolated from porcine aortic valves and studied how traditional TCPS culture, which presents a non-physiologically stiff environment, and TGF-β1 affect native VIC phenotypes. We carried out gene expression profiling using porcine genome microarrays from Affymetrix and found that traditional TCPS culture induces major changes in gene expression of native VICs, rendering these cells more activated and similar to cells treated with TGF-β1. We also monitored time-dependent effects induced by TGF-β1 by examining gene expression changes induced by TGF-β1 at 8 hours and 24 hours. Porcine aortic VICs were isolated and cultured with or without TGF-β1 treatment for RNA extraction and hybridization on Affymetrix microarrays. We included 3 biological replicates for each condition. P0 VICs were freshly isolated cells which had not been cultured. P2 VICs were cells that had been passaged 2 times and cultured on plastic plates in low serum media. Some of the P2 VICs were treated with TGF-β1 at 5ng/ml for 8 hours or 24 hours. All the control and TGF-β1-treated conditions were collected at the same time on day 3 of culture.
