Project description:We report transcripts bound by ADAR3 through RNA immunoprecipitation of U87 cells expressing 3X-FLAG tagged ADAR3 compard to control cells
Project description:We have analyzed RNA-seq data to identify A-to-I editing sites in two groups of samples: one group isolated from human U87 cell line expressing an active ADAR3 mutant while the other isolated from U87 cell line expressing the inactive counterpart of the ADAR3 mutant. We compared these two groups of samples and identified sites whose editing levels are higher in the first group than in the second group.
Project description:Through immunoprecipitation of epitope-tagged ADAR3 protein, several ADAR3-bound RNAs have been reported till date. However, exogenous expression of proteins are usually associated with altered gene expression profiles and thus, can influence binding profiles of RNA-binding proteins (RBPs) being studied. Here, we used affinity-purified antibody to pull down ADAR3 endogenously expressed in U373 glioblastoma cells and identified transcripts significantly enriched in the ADAR3 immunoprecipitants over control. To serve as control, antisera isolated from rabbit prior to immunization with ADAR3 antigen was used to perform the IP.
Project description:After performing an in-vivo screening with U87 glioblastoma cells transduced with a knockdown library several genes could be identified. Lin7a which was one of the candidates was further evaluated. Single knockdown of Lin7a in U87 conferred a pro-invasive phenotype in-vitro and in-vivo. Overexpression of Lin7a in the Primary glioblastoma cell line T269 reduced its invasive phenotype. To decipher the underlying pathways U87 control, U87-shLIN7a and U87-shLin7a+Lin7A (rescue cells after re-expression of Lin7A) were analyzed after in-vitro culture by a transcription profiling Array.
