Expression data from HT-29, a human colonic epithelial cell line

ABSTRACT: Gene(s) in epithelial cells can be upregulated or downregulated by different stimuli in a tissue-specific manner. We used genome-wide microarray analysis to profile the expression of genes in HT-29 cells that are upregulated after stimulation with sodium butyrate (NaB) and subsequently downregulated by the addition of ciprofloxacin antibiotic. The specific aim was to evaluate genes that are associated with mucosal immunity.

Expression data from HT-29, a human colonic epithelial cell line

Project description:Gene(s) in epithelial cells can be upregulated or downregulated by different stimuli in a tissue-specific manner. We used genome-wide microarray analysis to profile the expression of genes in HT-29 cells that are upregulated after stimulation with sodium butyrate (NaB) and subsequently downregulated by the addition of ciprofloxacin antibiotic. The specific aim was to evaluate genes that are associated with mucosal immunity. HT-29 cells were stimulated with sodium butyrate (NaB) (n=3), NaB and ciprofloxacin (n=3) or culture media (unstimulated control, n=3) for 24 hours. RNA extracted from these cells were hybridized on Affymetrix microarrays.

Effect of sodium butyrate on colorectal cancer cell line HT-29

Project description:Analysis of colorectal cancer (CRC) cell line HT-29 treated with Sodium Butyrate. Sodium Butyrate, a HDAC inhibitor present in gut, can differentiate the undifferentiated HT-29 to enterocytes by the induction of brush border enzyme alkaline phosphatase. Results provide the transcriptional profiling underlying the butyrate-induced differentiation of CRC.

Gene microarray data for HT-29 monolayer and spheroids

Project description:Colorectal cancers have a rare population of cells that express specific cell surface markers, and are referred to as cancer stem cells (CSC). Targeting CSCs, implicated in tumor relapse, is a paradigm shifting approach for colorectal cancer. We used gene microarray to analyze gene expression in HT-29, a colon cancer cell line, grown as monolayer and spheroid and identify metabolic pathways that are upregulated. HT-29 monolayer cells were grown in DMEM/F12 media supplemented with 10% FBS, and 1X Antibiotic-Antimycotic liquid (AA); and spheroids were grown in stem cell media [DMEM:F12, 1X AA, 1X B27, epidermal growth factors, and fibroblast growth factor for five days. Total RNA was isolated using the mirVana™ miRNA Isolation Kit according to the manufacturer's protocol. RNA intergrity was confirmed on the Nanodrop ND-1000 and analyzed with Agilent 2100 bioanalyzer. The arrays were scanned with the Affymetrix 3000 7G plus scanner.

Folic Acid study in HT-29 cells

Project description:Low intracellular folate levels diminish the growth rate of HT-29 human colon cancer cells. This is accompanied by a metabolic shift from cytosolic glycolysis towards mitochondrial oxidative phosphorylation, as demonstrated by a lower lactate production and an increased mitochondrial oxygen consumption rate. To obtain insight in the molecular effects underlying these changes, the steady state gene expression profiles of HT-29 cells with different intracellular folate concentrations were compared. The gene expression profile of HT-29 cells with low intracellular folate levels (grown for 3 weeks in 10 ng/ml folic acid (PGA)) was clearly distinct from that of the other exposure conditions, which provide sufficient intracellular folate levels (100 ng/ml PGA, 10 ng/ml methyltetrahydrofolate (MTHF) or 100 ng/ml MTHF). Intracellular folate deficiency, contrary to expectation, did not lead to major changes in expression of genes involved in energy metabolism. This suggests that the shift towards mitochondrial oxidative phosphorylation is not mediated at the transcription level. Furthermore, only minor changes in the expression of folate metabolism related genes were observed. The changes that were observed were consistent with nucleotide salvage and in agreement with nucleotide need of the slow-growing folate-deficient HT-29 cells. The major observed effects were on cell cycle related gene expression, which was increased and interferon-responsive gene expression, which was reduced. The increase in cell cycle related gene expression seems compensatory to the reduced cell growth. Down-regulation of the interferon-response may be explained by decreased expression of signal transducer and activator of transcription 1 upon folate deficiency.
