RNA-seq analysis in human Glioblastom Stem Cells in response to ADAR-KD


ABSTRACT: Our observation suggest that ADAR may play important role to maintain GSC stemness. In order to address this hypothesis, we abrogated the expression of ADAR in GSCs using two distinct short and non-overlapping shot hairpin RNAs (shRNAs). A non-targeting control shRNA (shCONT) is used as control in these experiments. Both shRNAs significantly reduced ADAR protein expression. Depletion of ADAR impaired GSCs proliferation but did not affect matched DGCs. Similarly, lack of ADAR reduces GSC self-renewal capacity as assessed by in vitro limiting dilution assay . In order to identify the antitumor mechanisms triggered by ADAR depletion, we performed global transcriptional profiling through RNA-sequencing in GSCs upon ADAR knockdown. These analyses show that ADAR downregulation impairs the impairs the expression of genes involved in cancer proliferation, particularly those involved in cell cycle regulation
