    Differential readthrough transcripts upon depletion of SPT6, PNUTS, and PCF11. ( A ) Mean RNA-seq signal intensity shown at SPT6 readthrough targets (TES + 5 kb) in the different conditions. ( B ) Heatmap displaying differentially expressed readthrough transcripts in HeLa cells following SPT6 and/or PNUTS depletion. Readthrough transcripts with a log 2 FC >1 in the siSPT6 condition compared to the control condition were considered positive. The readthrough regions were identified as described in . The heatmap plots the average log2FC scores (siRNA/siCT) of these regions. Three distinct clusters were defined to characterize the varying responses to SPT6 and/or PNUTS depletion. The analysis was conducted using three independent biological replicates. ( C ) Box-plots showing the median log 2 FC of readthrough transcripts relative to the control condition for the three clusters shown in panel (B). ( D – F ) Same as in panels (A)–(C) but for SPT6 and/or PCF11 depletion. ( G ) CTNND1 gene locus featuring RNA-seq data (positive strand) following the use of the indicated siRNAs. The lower panel (PAS) displays the locations of human PASs as defined by Zhang et al. . The arrow highlights readthrough transcription. The scale is shown at the top right corner of the figure.

    Figure Lengend Snippet: Differential readthrough transcripts upon depletion of SPT6, PNUTS, and PCF11. ( A ) Mean RNA-seq signal intensity shown at SPT6 readthrough targets (TES + 5 kb) in the different conditions. ( B ) Heatmap displaying differentially expressed readthrough transcripts in HeLa cells following SPT6 and/or PNUTS depletion. Readthrough transcripts with a log 2 FC >1 in the siSPT6 condition compared to the control condition were considered positive. The readthrough regions were identified as described in . The heatmap plots the average log2FC scores (siRNA/siCT) of these regions. Three distinct clusters were defined to characterize the varying responses to SPT6 and/or PNUTS depletion. The analysis was conducted using three independent biological replicates. ( C ) Box-plots showing the median log 2 FC of readthrough transcripts relative to the control condition for the three clusters shown in panel (B). ( D – F ) Same as in panels (A)–(C) but for SPT6 and/or PCF11 depletion. ( G ) CTNND1 gene locus featuring RNA-seq data (positive strand) following the use of the indicated siRNAs. The lower panel (PAS) displays the locations of human PASs as defined by Zhang et al. . The arrow highlights readthrough transcription. The scale is shown at the top right corner of the figure.

    Article Snippet: Control short hairpin RNA (shRNA) sequence (shCT) or shRNA sequence targeting PNUTS (see references in ) were cloned into the pLKO.1-TRC cloning vector (gift from David Root, Addgene plasmid #10878; http://n2t.net/addgene:10878 ; RRID: Addgene_10 878) according to the manufacturer’s instructions.

    Differential PROMPTs regulation upon depletion of SPT6, PNUTS, and PCF11. ( A ) Mean RNA-seq signal intensity shown at SPT6 PROMPT targets (TSS, -5 kb) in the different conditions. ( B ) Heatmap displaying differentially expressed PROMPTs in HeLa cells following SPT6 and/or PNUTS depletion. PROMPTs with a log 2 FC >1 in the siSPT6 condition compared to the control condition were considered positive. PROMPT regions were identified as described in . The heatmap plots the average log 2 FC scores (siRNA/siCT) of these regions. Three distinct clusters were defined to characterize the varying responses to SPT6 and/or PNUTS depletion. The analysis was conducted using three independent biological replicates. ( C ) Box-plots showing the median log 2 FC of PROMPTs relative to the control condition for the three clusters shown in panel (B). ( D ) PXDN PROMPT levels were assayed by RT-qPCR in three independent experiments. Values were normalized to the siCT condition arbitrarily set to 1. ( E – G ) Same as in panels (A)–(C) but for SPT6 and/or PCF11 depletion. ( H ) Same as in panel (D) but for the GGCT gene. ( I ) PVT1 gene locus featuring RNA-seq data (positive strand is in positive values and negative strand in negative values) following the use of the indicated siRNAs. The lower panel (PAS) displays the locations of human PASs as defined by Zhang et al. . The arrow highlights PROMPTs. The scale is shown at the top right corner of the figure.
