Project description: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. SOX9 CHIP-seq was carried out using HT-29 cells.

Project description:To investigate the role of TGF-β1-regulated miRNAs in the progression of colorectal cancer,we performed comprehensive miRMA microarray analysis on RNA derived from typical human colorectal cancer cell lines and TGF-β1 knock-down human colorectal cancer cell lines. We identified a novel set of TGF-β1-related miRNAs.

Project description:BORIS expresses abnormally in colorectal cancer cells. Both the expression and the copy number of BORIS are remarkably higher in colorectal cancer cells than in normal colon or rectal cells. BORIS is potential diagnosis, prognosis or therapeutic target for colorectal cancer. To expand our view of the signaling pathway related with BORIS, altered gene expression by BORIS knockdown was assessed by microarray assay. To study the gene regulation by BORIS knockdown, microarray assay was applied to screen the gene expression regulated by BORIS siRNA in colorectal cancer cells HCT116 and Caco-2

Project description:Metastasis is the leading cause of cancer-related mortality. Cancer stem cells contribute to metastasis in the murine colon cancer models, but the underlying mechanisms are unclear. Here we report a Wnt ligand, Dickkopf2 (DKK2) is essential for colorectal cancer stemness. Genetic depletion of Dkk2 in intestinal epithelial or stem cells reduced tumorigenesis as well as expression of the stem cell marker gene Lgr5 in a model of colitis-associated cancer. Mechanistically, DKK2 activates c-Src followed by increased LGR5 expressing stem cells in colorectal cancer through degradation of HNF4α1. Splenic injection of DKK2-deficient cancer organoids into C57BL/6 mice resulted in a significant reduction of liver metastases compared to the control cancer organoids in spite of the presence of oncogenic mutations in Apc, Kras and Tp53 genes. These findings suggest that DKK2 is required for stemness of colorectal cancer cells, which in turn contributes to metastasis.
