Project description:The oncometabolite, 2-hydroxyglutarate (2HG), has been directly implicated in carcinogenesis; however, the underlying molecular mechanisms remain poorly understood. To elucidate the molecular mechanisms through which 2HG contributes to cancer progression, we performed transcriptome analysis in 2HG-treated colorectal cancer HCT116 and HT29 cells.
Project description:In the present study we have isolated and characterized cancer stem cells and non-cancer stem cells (bulk tumor cells) from high grade human colorectal cancer cell line HCT116 and low grade human colorectal cancer cell line HT29. For this study, cancer stem cells and non-cancer stem cells (bulk tumor cells) were isolated from HCT116 and HT29 human colorectal cancer cell line. For isolating cancer stem cells by FACS, CD44 and CD166 tagged with V450 and PE respectively were used. CD44+CD166+ was the cancer stem cell population and CD44-CD166- was designated as the non-cancer stem cell (bulk tumor cells) population for this study. RNA was isolated from the isolated cell populations and microarray was done to study the whole genome transcriptomic changes.
Project description:HCT116 wild type cells express p53. The isogenic HCT116 p53KO cells have the p53 gene knocked out. Cells were treated for 16 hours. Dosages for leptomycin B treatment was 2 nM and 20 nM. Measuring the gene expression profile of the isogenic cell lines when the cells were treated with leptomycin B at different concentrations

Project description:The RNA samples from HT-29 (ATCC) colon cancer cell line were reverse transcribed into cDNAs and categorized in 3 groups with different concentrations of 5-aza-deoxy-cytidine (5-Aza); in each group three replicative 150 mm cultures were treated with: 1) dimethyl sulfoxide (vehicle alone, 0 μM 5-Aza); 2) 5μM 5-Aza and 3) 10 μM 5-Aza; for five days We then used Affymetrix microarray platform to profile the gene expression of the 3 HT29 cell groups (3 replicates in each group) in order to search for differentially expressed genes
Project description:Purpose: To identify differentially expressed genes in HT29 colon cancer cells after treatment with a novel formulation of camptothecin with β-cyclodextrin-EDTA-Fe3O4 nanoparticle-conjugated nanocarriers (CPT-CEF) Methods:Treated HT29 cell lines with CPT-CEF, isolated total RNA from HT29 colon cancer cells, and prepared library for RNA sequencing. Carried out comparative transcriptomic studies between treated and untreated cells to find out which gene functions were dysregulated by CPT-CEF. Results: The study yielded 247 DEGs ((FDR<0.05, FC>2.0) that were affected by CPT-CEF treatment in the HT29 colon cancer cells. The results obtained from cell cycle analysis, mitochondrial depolarization assay and acridium orange/propidium iodide double staining showed potential of CPT-CEF in cancer cell inhibition. Conclusion: Our study successfully identified DEGs in the CPT-CEF treated HT29 colon cancer cells that pointed to inhibition of cancer progression. To further affirm, animal studies are needed.
Project description:The whole-genome oligonucleotide microarray analysis of NS398-treated HT29 colon adenocarcinoma cells samples can give an insight into global molecular background of selective COX2 inhibitor administration in order to find other target molecules and pathways influenced by NS398 selective COX2 inhibitor treatment in the epithelial cells.
