ABSTRACT: we found that EHF allowed colon tumor cells to escape p53-mediated apoptosis.We performed microarray analysis to find the target genes of EHF. A colorecal cancer cell line HCT116 was transfected with an siRNA targeting EHF or negative control.

Project description:Transcriptional profiling of HCT116 cells compared to untreated control with HCT116 cells transfected with ZNF746 siRNA plasmid. Goal was to determine the effects of ZNF746 gene transfection on CRC progression. Two-condition experiment, HCT116 vs. ZNF746 siRNA.
Project description:To examine whether depletion of CD44 might affect antioxidant gene expression in cancer cells, HCT116 cells were transfected with CD44 or control siRNAs and subjected to cDNA microarray analysis. Although the CD44 siRNA was found to deplete the cells of CD44 mRNA, the expression of antioxidant genes was largely unaffected. HCT116 cells were transfected with CD44 or control siRNAs and subjected to cDNA microarray analysis. Two replicates per siRNA.

Project description:Investigation of whole genome gene expression level changes in HCT116 cells upon knockdown of Tip60 or p400, compared to control siRNA-transfected cells. Two different siRNA directed against Tip60 were used and experiments were done in duplicate. Same for p400-targetting or control siRNA. Hybridization experiment using total RNA recovered from independent cell cultures of HCT116 transfected using control, Tip60-targetting or p400-targetting siRNA.
Project description:Several members of SRSF family play wide-ranging roles in the regulation of transcription and post-splicing processes as well as splice sites selection. Although the expression of SRSF3 was reported to be overexpressed in several cancers, the roles of SRSF3 in the cancer cells are almost unknown. We analyzed differentially expressed genes in SRSF3 siRNA-treated HCT116 cells and identified the specific pathways regulated by SRSF3. After treatment of HCT116 cells with SRSF3 (sample 02) or control (sample 01) siRNA, total RNA was extracted using RNeasy Mini Kit (Qiagen, Valencia, CA). The quality of the purified RNA and its applicability for microarray analysis were assessed by the Agilent 2100 Bioanalyzer using a RNA 6000 Nano Labchip kit (Agilent Technologies, Palo Alto, CA, USA). Total RNA (400 ng) was used for amplification, labeling and hybridization to a whole human genome oligoDNA microarray (4x44k; Agilent) according to the manufacture’s instructions.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using RNA sequencing analysis to evaluate the effects of si-LINC00152 on the mRNA of human colon cancer cell line HCT116. Methods: Human colon cancer cell line HCT116 was transfected with a control non-targeting siRNA to cells or transfected with siRNA targeting LINC00152 for 36 hours in DMEM medium (with 10% serum). Total RNA were extracted and detected by Illumina high-throughput RNA sequencing data analysis. 2 independent biological replicates were plated, transfected in parallel for each control and siRNA. Results: Log-fold changes of up- or down-regulated mRNAs between the control and experiment group were selected with a significance threshold of p<0.05. There are 90 mRNAs were up-regulated and 159 were down-regulated in “si-LINC00152” group comparing to “control” group. Conclusions: Our study describes the mRNA changes of human colon cancer cell line HCT116 transfected with LINC00152 siRNA.
Project description:Yes-associated protein 1 (YAP1) is an effector of Hippo pathway, which is critical for regulating organ size, cell proliferation and tumor growth in mammals. YAP1 is known to be involved in tumorigenesis in several tissues, yet its role in colorectal cancer(CRC) is not established. To investigate the effect of YAP1 in CRC, we used microarrays to compared human colon cancer cell line HCT116 transfected with a control non-targeting siRNA to cells and transfected with siRNA targeting YAP1.
