Dysregulation of iron homeostasis may be a pathogenic factor in age-related macular degeneration (AMD). Meanwhile, the formation of complement-containing deposits under the retinal pigment epithelial (RPE) cell layer is a pathognomonic feature of AMD. In this study, we investigated the molecular mechanisms by which complement component 3 (C3), a central protein in the complement cascade, is up-regulated by iron in RPE cells. Modulation of TGF-β signaling, involving ERK1/2, SMAD3, and CCAAT/enhan ...[more]
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 μM FAC for 48h/2d. Gene expression was compared between untreated and FAC-treated ARPE-19 cells, with three biological replicates in each.
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 cultured cell line ARPE-19 is frequently employed in studies of rpe function. Here we have identified the microRNAs expressed in RPE cells in the presence and absence of PDTC (pyrrolidine dithiocarbamate), an antioxidant. Analysis used microrNA extracted from untreated cells as a control for cells treated with PDTC
Project description:ARPE-19 cells were either laser treated or not, and analyzed 2, 6 and 24 hours after laser treatment. In addition, the cells were treated with high or low glucose (T2D complications analysis). The difference in glucose levels did not make much difference in regards to gene expression. 52 ARPE-19 samples including controls and laser-treated samples. Separate analysis for high and low glucose levels.
Project description:This study compared the gene expression change of ARPE-19 cells before and after adriamycin treatment Overall design: ARPE-19 cells were treated with 1μM adriamycin for 24 h compared with control
