Comparisons of IGS-derived non-coding RNA in SETX knock-out compared to control cells: regions surrounding qPCR amplicons. Normalized TGIRT RNAseq data are shown at the locations in the IGS region of the rDNA surrounding locations of qPCR amplicons shown in Fig. 7 A. Positive-strand and negative-strand reads are shown in the control cells (black) or SETX KO cells (red) as indicated. Plus: Sense strand of rDNA; Minus: Antisense strand of rDNA.
