Genome-wide CRISPR interference screen identifies long non-coding RNA DARS1-AS1 as a novel regulator of glioblastoma tumorigenesis.


ABSTRACT: There are over 15,000 long (>200 nucleotides) noncoding RNA (lncRNAs) genes in the human genome, but only few of them has been functionally characterized. Emerging evidence has shown that long non-coding RNAs (lncRNAs) modulate diverse biological processes and mediate tumor-promoting/suppressing effects and serve as independent diagnostic/prognostic biomarkers in cancer. However, the role and function mechanism of the lncRNA/RBP-mediated regulatory circuits in determining the functional characteristics of GSCs underlying GBM pathogenesis remains poorly understood. To fill this gap, we combined CRISPR (clustered regularly interspaced short palindromic repeat) interference (CRISPRi), with large-scale computational analysis of The Cancer Genome Atlas (TCGA) to systematically identify the functional lncRNAs with clinically relevant expression in GBM.
