Transcriptome of the modified human cell lines was examined using standard RNA-Seq analysis of polyA fraction as well as small RNAs, including small nuclear RNAs, micro-RNAs and snoRNAs. Our findings confirmed the selectivity of CRISPR/Cas9 editing activity regarding snoRNAs of interest. Analysis of the host gene RNA structure demonstrated partial alterations in mature GAS5 RNA, namely, exon skipping and formation of additional non-canonical exon-exon junctions, only for single obtained cell lines.
Thus, the possibility of obtaining viable cell lines with the suppressed activity of a single snoRNA was demonstrated for studying non-canonical functions of individual snoRNAs, as well as their role in gene expression regulation, post-transcriptional maturation of rRNAs and ribosome assembly.
