Project description:miR-145 is downregulated in multiple cancers. The introduction of miR-145 could alleviate the tumor burden in the pancreatic cancer mouse model. However, how miR-145 mediates the tumor suppression is still an open question. In this study, we aimed to identify the targets of miR-145 using a SILAC approach.

Project description:Primary objectives: Study the chemopreventive potential of 5-aminosalicylic acid (5-ASA) and ursodeoxycholic acid (UDCA) in UC by evaluating the effect of treatment on abberant crypt foci (ACF) number, size and rate of dysplasia.
Primary endpoints: 1) Study the chemopreventive potential of 5-ASA and UDCA in UC by evaluating the effect of treatment on ACF number.2) Gain mechanistic insight into the chemopreventive properties of 5-ASA and UDCA by genome-wide array based mRNA expression analysis of UC normal colonic mucosa before and after treatment.

Project description:Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with preiods of active disease followed by remission. We performed a whole-genome transcriptional analysis of colonic biopsies from patients with histologically active and inactive UC, as well as non-inflammatory controls. Ulcerative colitis patients and non-inflammatory controls were collected for RNA extraction and hybridization on Affymetrix microarrays. Inclusion criteria for UC patients were: age between 18 and 65, diagnosis of UC established at least 6 months before inclusion and exclusion of concomitant infection. Active disease was defined by endoscopic and histologic score: Mayo sub score >=2 and MATTS >=3 respectively . Inactive disease was also defined by endoscopic and histologic score: Mayo sub score =0 and MATTS <=2 respectively, and a remission state for a minimum of 5 month prior to biopsy collection, and remained inactive for at least 6 months after. Uninvolved mucosa from patients with active UC was defined as a colonic segment with completely normal endoscopic appearance, normal histology, and absence of any previous evidence of active disease. Finally, a total of 43 biopsies were analyzed: 13 healthy controls, 8 inactive UC, 7 non-involved active UC and 15 involved active UC.

Project description:Activation of inflammatory pathways in human IBD. Leukocyte recruitment pathways including those for eosiniphils are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory eotaxin (CCL11) dependent networks would be up regulated in the colon of pediatric patients with Ulcerative Colitis (UC), and that these would regulate eosinophil recruitment to the gut. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Colon biopsy samples were obtained from UC patients at diagnosis, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, and biological networks were identified using Ingenuity software. Data suggested that a leukocyte recruitment network which includeds CCL11 is up regulated in pediatric UC at diagnosis. The degree of up regulation of these genes compared to healthy controls was remarkably conserved within the UC patient group, suggesting common mechanisms of mucosal inflammation. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Keywords: Single time point in UC and healthy controls. Colon RNA was isolated from biopsies obtained from UC at diagnosis and healthy controls. Samples were obtained from the most proximal affected segment of colon. Microarray experiments were performed as described in the CCHMC microarray core, and data was analyzed as described above in the summary. The '107' internal control CEL files (for batches 1,2,4,5) used for ormalization of the Sample VALUEs are also contained within this data set.

Project description:miR-145 is a tumor suppressor miRNA in various malignancies including pancreatic cancer. How miR-145 regulates expression of other miRNAs could provide a panoramic view of the development of pancreatic cancer. Therefore, in this project, we aimed to characterize how other miRNAs are affected by miR-145 in hope for understanding proteomic changes that are not explained by miR-145 alone.

Project description:miR-145 is a tumor suppressor miRNA in various malignancies including pancreatic cancer. Identification of miR-145 targets can lead to more understanding of the development of pancreatic cancer. Therefore, in this project, we aimed to characterize the changes of transcriptomes caused by miR-145 to identify more miR-145 target transcripts.
