Project description:To further understand different gene expression of miR-31 knockout mouse colon and normal colon, we have employed colonic epithelium microarray expression profiling as a discovery platform to identify different genes with miR-31 knockout mouse colon and normal colon.comparision with normal colonic epithelium,upgene is 285 and downgene is 178 in knockout group.
Project description:This is a prospective-retrospective study to determine if the expression of the miRNA’s miR-31-3p and miR-31-5p are prognostic of patient outcomes or predictive of the benefit from anti-EGFR therapy in stage III Colon Cancer. The present study will utilize FFPE tumor samples collected from patients enrolled in the PETACC-8 study conducted by the Fédération Francophone de Cancérologie Digestive (FFCD). This phase 3 clinical trial prospectively randomized fully resected stage III colon cancer patients to receive adjuvant treatment with either FOLFOX-4 plus cetuximab or FLOFOX-4 alone.
Project description:Transcriptomics analyses in these Zn-deficient rats revealed the molecular basis of ESCC abrogation by miR-31 knockout: Egln3, a negative regulator of NF-FB, was shown to be a direct miR-31 target; miR-31 inhibition/deletion resulted in suppression of miR-31-associated-EGLN3-NF-KB controlled inflammatory pathways.
Project description:To further understand different gene expression of islr knockout mouse colon and normal colon, we have employed colon samples microarray expression profiling as a discovery platform to identify different genes with Islr knockout mouse colon and normal colon. Comparison with normal colon, significantly upgene is 779 and downgene is 996 in knockout group.
Project description:This project was aimed to identify the proteomic of pri-miR-31 interacting in naïve and activated cd4+ T cells. Immunoprecipitates pulled down by pri-miR-31 were subjected to LC-MS. Our results reveal the interacting protein in different state of CD4+ T cells.
Project description:The clinical course of Crohn's disease (CD) is highly heterogeneous, confounding effective personalized therapy. There is a critical need to better understand the cellular mechanisms responsible for the variability in disease presentation and response to therapeutic modalities. We carried out whole transcriptome profiling in colon tissue from adult CD patients and controls and found that CD patients segregate into the same two molecular subtypes based on mRNA, long non-coding RNA, or microRNA profiles. MicroRNA-31 (miR-31) in colonic epithelium was identified as a primary contributor to this molecular stratification. We further performed small RNA-seq on formalin-fixed paraffin embedded colon and ileum biopsies obtained at the time of diagnosis from 130 treatment-naïve pediatric CD patients and controls. Colonic expression of miR-31 in pediatric patients was identified as predictive of either medically refractory rectal CD or fibrostenotic ileal CD. Our study reveals miRNAs as important molecular stratifiers and prognostic determinants of CD subtypes.
Project description:Overexpression of miR-31 inhibits the migration and invasion ability of glioma cell. We sought to obtain the genes regulated by mir-31 in glioma cell line.
