EWS siRNA knock-down in HeLa cell line


ABSTRACT: HeLa cell line was trasfected by a EWS siRNA oligo causing knock-down of EWS or a siRNA scrambled oligo Three biological replicates were labeled in direct and dye-swap microarray experiments and hybridized onto an Agilent custom splicing-sensitive microarray platform.

The Ewing sarcoma (EWS) protein is a member of the TET (TLS/EWS/TAF15) family of RNA- and DNA-binding proteins whose expression is altered in cancer. We report that EWS depletion results in alternative splicing changes of genes involved in DNA repair and genotoxic stress signaling, including ABL1, CHEK2, and MAP4K2. Chromatin and RNA crosslinking immunoprecipitation results indicate that EWS cotranscriptionally binds to its target RNAs. This association is reduced upon irradiation of cells with  ...[more]
