Project description:Anti-APC ChIP-seq data were collected from HCT-116 cells and 3,985 genomic sequences were found to be enriched in both independent biological replicates.
Project description:Gene expression data were collected by RNA-seq from HCT-116 cells in the presence or absence of siRNA targeting APC and 1,376 transcripts changed in expression following APC silencing were identified relative to scrambled siRNA-transfected and untreated controls.
Project description:Gene expression in HCT-116 cells infected with shCtrl and shRFWD3 was detected with a PrimeView human gene expression array. We performed Affymetrix Human Gene Chip Prime View analysis on shCtrl and shRFWD3 HCT 116 cells. Of the 1305 differentially expressed genes (DEGs) found in shRFWD3 and shCtrl HCT 116 cells, 629 were up-regulated and 676 were down-regulated based on the threshold of absolute fold change ≥ 2 and FDR < 0.05
Project description:To identify the direct molecular targets of 6S, gene microarrays were used to profile gene expression in HCT-116 cells treated with 6S (20 uM for 24 h) comparing with HCT-116 cells treated with DMSO (control). Two-class comparisons. HCT-116 cells treated with 6S (20 uM for 24 h) vs. HCT-116 cells treated with DMSO control;Biological replicates: 4 replicates for each group.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived HCT-116 cell transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis. Methods: HCT-116 cell mRNA profiles of HCT-116-GOLPH3-Vector and HCT-116-GOLPH3-Overepression were generated by deep sequencing, in triplicate, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Results: RNA sequencing (RNA-seq) was used to investigate gene expression in HCT-116-PMSCV-Vector and HCT-116-PMSCV GOLPH3 cells, while Gene Ontology (GO) was used to annotate the various functional genes. By comparing the differentially expressed genes, we noticed that GOLPH3 was associated with EMT. Gene set enrichment analysis (GSEA) analysis of the RNA-seq results based on the GSE77953 dataset was performed to investigate the biological functions of HCT-116-PMSCV-Vector and HCT-116-PMSCV-GOLPH3 cells. The findings suggested that GOLPH3 expression was positively associated with colon cancer cell autophagy. Signal pathway enrichment was next analyzed based on the differential expression of genes between HCT-116-PMSCV-Vector and HCT-116-PMSCV-GOLPH3 cells, as examined by RNA-seq. Notably, GOLPH3 has correlated with the PI3K/Akt signaling pathway. Conclusions: Our study represents the first detailed analysis of HCT-116 cell transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.

Project description:Human somatic cells may contain up to seven members of the histone H1 family contributing to chromatin compaction and regulation of nuclear processes, apparently with certain subtype specificities. Previous studies in T47D breast cancer cells determined that H1 variants are distributed in a variant-specific manner throughout the genome. In particular, we observed a clear enrichment of linker histone H1X within SVA and SINE repetitive sequences. To extend our results and study whether H1X is universally enriched within these types of repeats, we have performed ChIP-Seq of endogenous H1X in five additional cancer cell lines (HeLa, MCF-7, SK-N-SH, HCT-116, and SK-MEL-147).
