Protein synthesis was then assessed with a puromycin incorporation assay. β-tubulin was used as a loading control. (E) Quantification of puromycin signal in D. Each bar represents the mean + SEM; n = 3. Bars marked with asterisks are significantly different from the control; ANOVA; ** = p < 0.01; ns indicates no significance. (F) The DB008-dependent increase in protein aggregation requires PARP16 C169. OVCAR3 PARP16 KO cells stably expressing PARP16 WT or PARP16 C169S were treated with 0 or 1 µM DB008 for 16 hours. Protein aggregation was then assessed with the proteostat aggresome detection reagent. The DNA was stained with DAPI. Scale bar = 25 µm.

    Figure Lengend Snippet: (A and B) Inhibition by DB008 requires PARP16 C169. (A) IP-Western showing PARP16 MARylation ( top panel ) or PARylation levels in whole cell extracts (WCE; bottom panel ) of OVCAR3 PARP16 KO cells stably expressing FLAG-PARP16 or FLAG-PARP16 C169S after treatment with 1 µM DB008 for 4 hours. (B) Quantification of MAR signal from A. Each bar represents the mean + SEM; n = 3. Bars marked with asterisks are significantly different from the control; ANOVA; * = p < 0.05; ns indicates no significance. (C) Anchorage-independent growth is unaffected in cells expressing PARP16 C169S. OVCAR3 PARP16 KO cells stably expressing PARP16 WT or PARP16 C169S were grown in soft agar with media containing 0 or 1 µM DB008 for 3 weeks, replenishing media once per week. Anchorage-independent growth was then measured with crystal violet staining. Quantification of crystal violet absorbance in B. Each bar represents the mean + SEM; n = 3. Bars marked with asterisks are significantly different from the control; ANOVA; * = p < 0.05; ns indicates no significance.
