MicroRNA expression profiling among WTX low human colorectal cancer tissues and matched adjacent WTX high normal colorectal mucosa

ABSTRACT: Comparing to matched normal mucosa, WTX was lost in most of human colorectal cancers (Zhang et al., 2016). We analyzed the microRNA expression profiling among WTX low human colorectal cancer tissues and matched adjacent WTX high normal colorectal mucosa. The aimed to identify the unique signature of miRNAs which related to WTX loss in human colorectal cancers.

Gene expression profiling after induction of WTX in HEK293 cells

Project description:WTX encodes a tumor suppressor, frequently inactivated in Wilms tumor, with both plasma membrane and nuclear localization. WTX has been implicated in beta-catenin turnover, but its effect on nuclear proteins is unknown. We report an interaction between WTX and p53, derived from the unexpected observation of WTX, p53 and E1B 55K colocalization within the characteristic cytoplasmic body of adenovirus-transformed kidney cells. In other cells without adenovirus expression, the C-terminal domain of WTX binds to the DNA binding domain of p53, enhances its binding to CBP, and increases CBP/p300-mediated acetylation of p53 at Lys 382. WTX knockdown accelerates CBP/p300 protein turnover and attenuates this modification of p53. In p53-reconstitution experiments, cell cycle arrest, apoptosis, and p53-target gene expression are suppressed by depletion of WTX. Together, these results suggest that WTX modulates p53 function, in part through regulation of its activator CBP/p300.

Super-enhancer landscape profiling in primary colorectal carcinoma

Project description:Purpose: Examine H3K27ac enhancer and super-enhancer landscape differences between primary colorectal carcinoma and adjacent normal mucosa towards the identification of novel downstream targets. Methods: H3K27ac ChIP-seq and RNA-seq were performed on fresh primary colorectal carcinoma samples and normal colonic mucosa, from human patient samples. Results: We identified 2026 total super-enhancers in our cohort, between primary colorectal and normal mucosa. We quantified differences in H3K27ac signal within this space, between tumor and normal, and identified putative downstream target genes through integration with sample matched RNA-seq using a positive linear correlation model to identifty putative target genes.

WTX interacts with the transcriptional regulator TRIM28 to mediate cellular differentiation

Project description:WTX encodes a tumor suppressor implicated in Wilms tumor and in mesenchymal differentiation, with distinct functions in the cytoplasm, at the plasma membrane and in the nucleus. Here we report that the transcriptional corepressor TRIM28 is the major binding partner for nuclear WTX. The WTX-TRIM28 interaction supports chromatin binding by TRIM28, enhancing transcriptional silencing of some TRIM28 target sequences. In mouse ES cells, where TRIM28-mediated silencing of repetitive sequences is best characterized, Wtx knockdown similarly derepresses endogenous retroviruses and LINE elements. We performed digital gene expression (DGE) profiling using Helicos RNA sequencing. Helicos sequencing does not involve an amplification step, hence it has less bias, especially in sequencing of repetitive elements. We sequenced RNA extracted from mouse ESCs harboring GFP, Wtx or Trim28 hairpins. The resulting sequence reads were aligned with the RefSeq database as well as Repbase, which is a database for the repetitive sequences.

microRNA expression profile in colorectal adenoma and cancer

Project description:We evaluated the profile of miRNA expression in 6 colorectal adenoma (CRA), 6 colorectal adenocarcinoma (CRC) and 6 matched normal mucosa (NOR) using the Exiqon miRCURY LNA microRNA array,7th generation. We found that global dysregulated miRNAs between colorectal lesions and normal mucosa. Our findings implicates that dysregulation of miRNAs may play important role in the carcinogenesis and present therapeutic targets for CRC.
