Genome-wide maps of SOX9 binding sites in human colorectal cancer cells

ABSTRACT: Aberrant expression of SOX9 in human colorectal cancer cells suggests its roles in the development of colorectal cancer. To gain insight into SOX9-mediated transcriptional regulation in colorectal cancer cells, we attempted to identify its physiological targets on a genome-scale using chromatin immunoprecipitation (ChIP) followed by sequencing (ChIP-seq) in HT-29, human colorectal cancer cells.

Expression data of colorectal cancer HT-29 cells

Project description:Colorectal cancer HT-29 cell line is a comonly-used human cancer cell line. We have used this cell line for examining the effect of various anticancer compounds on gene expression and we obtained gene expression data of untreated HT-29 cells as a control data for the analysis.

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.

Effects of IFITM1 knockdown in colorectal cancer

Project description:Interferon-induced transmembrane protein 1 (IFITM1) is one of the three members of the interferon-induced transmembrane family and has recently been identified as a new molecular marker in human colorectal cancer. However, its functional roles in colorectal cancer are still elusive. In this study, we investigate the gene expression profiling of HT-29 cells with IFITM1 knockdown. We revealed that several invasive- and carcinogenesis-related genes were differentially expressed. We transfected siRNAs targeting firefly luciferase and human IFITM1 mRNAs into HT-29 colorectal adenocarcinoma cells. At 72 h post-transfection, total RNA was harvested for microarray hybridization. A siLuc-transfected sample was used as the baseline control.

Expression profiles of piRNAs in Colorectal Cancer (CRC) cell lines

Project description:To investigate the presence and abundance of piRNAs in Colorectal Cancer (CRC), we performed deep-sequencing of the small RNA transcriptome of eight human CRC cell lines (HT-115, Caco-2, SW-1417, SW 403, COLO 205, HT-29, HCT 116 and RKO).

Sox9 directs divergent epigenomic states in brain tumor subtypes

Project description:Epigenetic dysregulation is a universal feature of cancer that results in altered patterns of gene expression that drive malignancy. Brain tumors exhibit subtype-specific epigenetic alterations, however the molecular mechanisms responsible for these diverse epigenetic states remain unclear. Here we show that the developmental transcription factor Sox9 differentially regulates epigenomic states in high-grade glioma (HGG) and ependymoma (EPN). These contrasting roles for Sox9 correspond with protein interactions with histone deacetylating complexes in HGG, and association with the Rela oncofusion in EPN. Together, our studies demonstrate how epigenomic states are differentially regulated in distinct subtypes of brain tumors, while revealing divergent roles for Sox9 in HGG and EPN tumorigenesis.

SOX9 Drives WNT Pathway Activation in Prostate Cancer [gene expression]

Project description:SOX9 is critical for prostate development and is implicated in prostate cancer, we used transcriptome profiling in combination with SOX9 ChIP-seq to identify genes and pathways it regulates in normal or neoplastic epithelium. We used microarrays to detail the global programme of gene expression in TMPRSS2/ERG fusion positive prostate cancer cell line with high basal expression of SOX9 by comparing the expression changes between SOX9 knockdown versus control.
