Abstract
<jats:p><p>SLFN11-dependent suppression of rRNA synthesis by BTZ. <b>A,</b> Representative immunofluorescence images showing total SLFN11 (green, no preextraction) and DAPI (blue) in parental and SLFN11 KO KMS-34 cells. Scale bars, 10 μm. <b>B,</b> SLFN11 immunoblots for whole-cell lysates from WT and SLFN11 KO clones of KMS-34 cells. <b>C,</b> Representative immunofluorescence images showing EU incorporation (green) and DAPI (blue). Top, KMS-34 cells. Bottom, KMS-27 cells. WT and SLFN11 KO clones were treated with BTZ (0.1 μmol/L) for indicated time points. Scale bars, 5 μm. <b>D,</b> Quantification of EU signal intensities in individual cells. Mean ± SEM are shown. Top, KMS-34 cells (threshold = 80). Bottom, KMS-27 cells (threshold = 70). Percentages of cells below threshold are indicated. ****, <i>P</i> < 0.0001 (one-way ANOVA). a.u., arbitrary units.</p></jats:p>
