Transcription profiling of human colon Caco-2 cells treated with hydroxytyrosol (HTy) and hydroxytyrosyl ethyl ether (HTy-Et)

ABSTRACT: The anticarcinogenic activity of hydroxytyrosyl ethyl ether (HTy-Et) compared to its precursor hydroxytyrosol (HTy) has been studied in human Caco-2 colon adenocarcinoma cells. Changes in global gene expression in Caco-2 cells exposed to HTy and HTy-Et for 24 h were evaluated using Affymetrix array. Microarray analysis showed that after exposure to HTy and HTy-Et, 451 and 977 genes respectively were differentially expressed compared with untreated cells (P < 0.005; FDR=0). Results show that HTy and its lipophilic ether derivative alter genes related with cancer prevention, which includes inducing cell cycle arrest, promoting apoptosis and enhancing xenobiotic metabolism. Caco-2 cells were treated with 10 M-NM-

Transcription profiling by array of human Caco-2 cells with ATP8B1 knock down

Project description:To gain insights whether and if activation of the nuclear receptor FXR is involved in the disease ethiology of ATP8B1 deficiency, we contstructed a Caco-2 ATP8B1 knock down cell line and a Caco-2 empty vector control cell line. Furthermore we expect to gain new insights from transcriptional profiling of ATP8B1 deficient cells.

Expression data from Caco-2 cells expressing TLR4 and associated mutants

Project description:Common missense mutations (D299G, T399I) have been recently identified in the human TLR4 gene. The aim of this study was to determine how TLR4 and associated mutants affect gene expression in Caco-2 cells. We used microarrays to asses gene expression profiles in Caco-2 stably overexpressing TLR4-WT, TLR4-D299G, TLR4-T399I or untransfected. Caco-2 clones stably overexpressing HA-tagged wildtype TLR4-WT, mutant TLR4-D299G or TLR4-T399I were generated. Prior to analysis, cell clones were cultured for 8 days in all experiments. RNA (triplicate) was extracted and hybridized on Affymetrix microarrays.

Modification of miRNA profile in Caco-2 cells by dietary lipids

Project description:The aim of this study was to detect miRNAs modified by biactive dietary lipids in a cellular model of enterocytes. The selected model was Caco-2 cells Differentiated Caco-2 cells were incubated with micelles containing the lipids for 24 and 48 hours. The expression leveles of the miRNAs were compared with cells treated with empty micelles. Four control and choelsterol samples, three DHA samples and two CLA samples were analyzed variables: Control (Empty micelles), Cholesterol 250 M-BM-5M 48h, DHA 200 M-BM-5M 24h, CLA 200M-BM-5M 24h Biological replicates Control: Samples 137, 159, 160, 210 Cholesterol: Samples 150, 151, 152, 219 DHA: Samples 141, 142, 143 CLA: Samples 144, 146
