Project description:The role of SPROUTY2 (SPRY2) in human colon cancer is controversial. Our data support a tumorigenic action of SPRY2. We use microarrays to identify SPRY2 target genes in human SW480 ADH colon carcinoma cell line.

Project description:The role of SPROUTY2 (SPRY2) in human colon cancer is controversial. Our data support a tumorigenic action of SPRY2. We use microarrays to identify SPRY2 target genes in human SW480 ADH colon carcinoma cell line. RNA was obtained from SW480 ADH cells, Mock transfected or transfected with WT or two differents SPRY2 genes mutants. Hybridization was performed on Affymetrix microarrays. We performed three independent experiments. Each experiment was conducted in triplicate.

Project description:Sprouty proteins are evolutionarily conserved modulators of mitogen-activated protein kinase pathway. Sprouty2 appears to function as a tumor suppressor in cancers, whereas we reported earlier that Sprouty2 functions as an oncogene in colorectal cancer. To further understand the oncogenic potential of Sprouty2 in the colon, microRNA expression profile of colon cancer cells was investigated. Sprouty2 suppression in HCT116 colon cancer cells significantly increased MicroRNA 194-5p. Sprouty2 dependent regulation of microRNA194-5p and its biological targets were studied further for their tumor suppressive actions in reducing epithelial-mesenchymal transition in colorectal cancer.

Sprouty2 dependent regulation of microRNA194-5p and its biological targets were studied further for their tumor suppressive actions in reducing epithelial-mesenchymal transition in colorectal cancer. Sprouty2 knockdown was performed by infecting HCT116 cells with three different lentivirus expressing shRNAs against human Sprouty2 mRNA and a control non targeted non-silencing shRNA (Sprouty2 MISSION shRNA Lentiviral Transduction Particles; TRCN 0000007522, TRCN 0000231589, TRCN 0000231588 and a non-targeted shRNA control from Sigma) following lentiviral transduction protocols provided by Sigma. Due to the random integration of the lentivirus into the host genome, varying levels of Sprouty2 gene knockdown was expected in puromycin resistant colonies. Three colonies in triplicate that demonstrated highest to lowest level of Sprouty2 suppression, as assessed by western blotting, were selected. RNA samples from these colonies and one from non-targeted shRNA expressing colony were prepared for microRNA expression profile analysis. Pooled RNA samples from each group were shipped to Exiqon for microRNA profiling based on miRCURY LNATM array technology.

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes
