Changes in NAD RNA capping upon HIV-1
infection. (A) Levels of
free NAD/NADH in control and HIV-1-infected cells (measured in biological
triplicates and technical duplicates, t-test). (B)
Scheme of the NAD captureSeq protocol applied to control and HIV-1-infected
cells. (C) Scatter plot showing the NAD captureSeq enrichment (+ADPRC
vs −ADPRC) in control (X-axis) and HIV-1-infected
samples (Y-axis), showing average values across replicates.
Highlighted sRNAs passed the criteria listed in Figure S1B, i.e., change in NAD cap abundance upon HIV-1 infection,
having specific enrichment in +ADPRC samples, sufficient read count
and consistency across replicates; these sRNAs are visualized in more
detail for individual replicates in panel (D). (D) Enrichment of RNAs
in NAD captureSeq analysis enriched in control cells versus HIV-1-infected
cells, matching highlighted sRNAs in Figure 1C. Blue circles show individual replicates;
the size of the circle corresponds to the number of mapped reads.
(E) sRNA–seq analysis of identified candidate sRNAs in control
and HIV-1-infected cells (prepared in biological triplicates).
