Figure Lengend Snippet: siSPRR3 depletion results in a reduction in the number of nucleoli per nucleus in MCF10A cells. A , siSPRR3 depletion with siGENOME siRNAs reduces the number of nucleoli per nucleus. Images and histograms from a genome-wide screen using Dharmacon/Horizon siGENOME siRNAs . The images show nuclei (Hoechst, blue ) and nucleoli (anti-fibrillarin, red ) after 72 h of treatment with the negative control (siGFP), positive control (siUTP4), or siSPRR3 siRNAs. Histograms show the distribution of cells that have the indicated number of nucleoli per nucleus. Light grey shows the distribution for the negative control, black shows the test condition, and dark grey shows overlap of the two frequencies. B , siSPRR3 depletion with siON-TARGET (siONT) SMARTPool siRNA reduces the number of nucleoli per nucleus. The images show nuclei and nucleoli after 72 h of treatment with the negative control (non-targeting siRNA, siNT), positive control (siUTP4), or siSPRR3 siRNAs. The shading in the histograms is as in A ). The data were collected across four replicates which are pooled in the histogram. C , siSPRR3 depletion with individual siONT SMARTPool siRNAs (deconvolution) reduces the number of nucleoli per nucleus. The images show nuclei and nucleoli after 72 h of treatment with the negative control (siNT), positive control (siNOL11), or representative siSPRR3 individual siRNAs (SPRR3-si1 and SPRR3-si2). The shading in the histograms is as in ( A ). The histograms include all three replicates pooled. The table summarizes each of four individual siONT SMARTPool siRNAs, showing that a reduction in nucleolar number correlates with a loss in cell viability. D , siSPRR3 (custom subpool of SPRR3-si1 and SPRR3-si2) reduces SPRR3 mRNA levels in MCF10A cells. RT-qPCR data of SPRR3 mRNA demonstrating knockdown after 72 h. The data were normalized to 7SL RNA abundance, then to siNT for comparison using the ΔΔC T method. The mean ± SEM are shown alongside individual data points, colored by replicate.

Figure Lengend Snippet: SPRR3 depletion reduces pre-rRNA transcription. A , schematic of the major steps in ribosome biogenesis in human cells. B , SPRR3 depletion inhibits nucleolar rRNA biogenesis. Representative images and quantification of control or SPRR3-depleted MCF10A cells (siONT SMARTpool) following anti-fibrillarin (FBL) staining and 5-EU incorporation. Scale bars are 10 μm. siNT is a non-targeting negative control siRNA. siPOLR1A is a positive control targeting the RNAPI subunit, POLR1A. The overall mean percent inhibition ± SEM is shown for each treatment, with each dot representing one well.

C , RT-qPCR analysis shows decreased 47S/45S pre-rRNA levels upon SPRR3 depletion in MCF10A cells. The mean ± SEM are shown alongside individual data points, colored by replicate. The data were normalized to 7SL RNA abundance, then to siNT for comparison using the ΔΔC T method. D , dual-luciferase reporter assay shows RNAPI promoter activity is reduced after SPRR3 depletion. The mean ± SEM are shown alongside individual data points, colored by replicate. The controls in these data have also been published in , without the inclusion of siSPRR3.

Figure Lengend Snippet: SPRR3 depletion causes reduced global translation (protein synthesis). A , representative image and quantification of puromycin incorporation shows reduced translation after SPRR3 depletion in MCF10A cells. α-puromycin shows puromycin incorporation as a proxy for global protein synthesis. Total protein is the trichloroethanol total protein stain loading control. Images were quantified with Bio-Rad Image Lab. The mean ± SEM are shown alongside individual data points, colored by replicate. siRPL4 is the positive control. Data were normalized to a non-targeting siRNA (siNT), then graphed and analyzed by ordinary one-way ANOVA with multiple comparisons against siNT and Holm-Šídák correction in GraphPad Prism. ∗∗∗, p < 0.001. The control data in this puromycin Western blot have also been published in without the SPRR3 data. B , summary table describing the effects of SPRR3 depletion on ribosome biogenesis and the nucleolus. SPRR3 depletion reduces nucleolar number, nucleolar rRNA biogenesis (5-EU incorporation assay), pre-rRNA transcript levels (RT-qPCR of 47S/45S rRNA), rDNA promoter activity (luciferase reporter assay), and global protein synthesis (puromycin incorporation assay). SPRR3 depletion was found to have no effect on the ratio of 18S to 28S rRNA nor to produce changes in pre-rRNA northern blots, indicating that SPRR3 does not affect rRNA processing. Taken together, this suggests that SPRR3 plays a role in pre-rRNA transcription and nucleolar rRNA biogenesis that is essential to the normal translational activity of ribosomes.
