Project description:This study compared the gene expression change of ARPE-19 cells before and after adriamycin treatment ARPE-19 cells were treated with 1μM adriamycin for 24 h compared with control
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: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: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:The retinal pigment epithelial (RPE) cell line ARPE-19 provides a widely-used alternative to native RPE. However, retention of the native RPE phenotype becomes problematic after multiple passages. We wished to determine if suitable culture conditions and differentiation could restore RPE-appropriate gene expression to ARPE-19. ARPE-19 cells at passages p9 to p12, grown in DMEM containing high glucose and pyruvate with 1% fetal bovine serum, were differentiated for up to 4 months. Using RNA-Seq, we compared the transcriptome of ARPE-19 cells kept in long-term culture with those cultured for 4 days. The 4 month cells developed the classic native RPE phenotype with heavy pigmentation. RNA-Seq analysis provided a comprehensive view of the relative abundance and differential expression of genes in the 4 month cells. Of the 16,757 genes with detectable signals, nearly 2435 genes were upregulated, and 931 genes were down-regulated with a fold change differences of 2 or more. Genes characteristic of RPE, including RPE65, RDH5 and RDH10, were greatly increased in ARPE-19 cells maintained at confluence for 4 months. Comparison with microarray data sets from human primary cell lines revealed important overall similarities in expression of "signature" genes. The results of this study demonstrate that ARPE-19 cells can express genes specific to native human RPE cells when appropriately cultured, and thus, can provide a relevant system to study differentiated cellular functions of RPE in vitro.
