Project description:RKO cells were treated with low doses of aphidicolin (0.2µM) that inhibit replicative DNA polymerases and induce a mild replication stress. ATAC-seq data were analysed on control cells (DMSO) and after 16h of treatment with aphidicolin
Project description:RKO cells were treated with low doses of aphidicolin (0,2µM) that inhibit replicative DNA polymerases and induce a mild replication stress. Expression data were analysed on control cells (DMSO), 16h of treatment (t0) and after release in complete new culture medium of 13h (N+1) using microarray (affymetrix Clarion S) We used microarray to analyse the impact of low replication stress on gene expression comparing DMSO or aphidicolin-treated cells at the end of the treatment (t0) and in daughter cells released from the replication stress (N+1).
Project description:Colon cancer cell line RKO grown on Matrigel form a luminal-like structure after the transfection of SPARCL1 gene, which may imply the differentiation of the cells. To indentify genes regulated by SPARCL1, we built two stable cell lines: RKO with pLXSN-SPARCL1 plasmid (RKO-SPARCL1) and RKO with pLXSN plasmid (RKO-pLXSN). Then we cultured these two cell lines on both plastic dish and dish cover with a layer of Matrigel. We used microarrays to undentify global gene expression change in RKO cells after the tranfection of SPARCL1.

We used microarrays to undentify global gene expression change in RKO cells after the tranfection of SPARCL1. Four samples including RKO-pLXSN cells cultured on plastic, RKO-pLXSN cells cultured on Matrigel, RKO-SPARCL1 cells cultured on plastic and RKO-SPARCL1 cells cultured on Matrigel were trypsinized and collected for RNA extraction and hybridization on Affymetrix microarray U133plus2.0. Supplementary files: * RLvsRP: up and down regulated genes comparing with RKO-SPARCL1(RL) and RKO-pLXSN(RP) cells cultured on plastic * RLMvsRPM: up and down regulated genes comparing with RKO-SPARCL1(RL) and RKO-pLXSN(RP) cells cultured on Matrigel
Project description:We present here the characterization of the replication timing program in 6 human cell lines : U2OS, RKO, 293T, HeLa, MRC5 and K562
Project description:Methylation analysis of normal lymphocytes, HCT116, RKO and SW480 In vitro methylated DNA (IVD) generated from normal lymphocytes, HCT116, RKO and SW480 genomic DNA was subjected to sodium bisulfite treatment and the DNA was analyzed for CpG methylation using the Infinium Methylation Array.
