    Validation of novel TDMD triggers. ( A ) Schematic of trigger site deletion (Δts) strategy to validate putative TDMD triggers. ( B , D ) Genomic organization of TDMD trigger transcripts with conservation and predicted miRNA base-pairing architecture of the trigger sites. Nucleotides predicted to base-pair with the miRNA are shown in bold. ( C , E ) qRT-PCR analysis of indicated miRNAs, relative to miR-16-5p, in WT and Δts MEFs. Parental MEFs or two independent Δts clones for each trigger site were infected with lentivirus expressing Cas9 and a nontargeting CRISPR guide (sgNT) or Zswim8- targeting guide (sg Zswim8 ). Values were normalized to expression level in sg Zswim8 for each condition. n = 3 technical replicates per clone, with individual data points plotted (mean ± SD shown). P -values were calculated by one-tailed Student's t -test. (*) P < 0.05, (**) P < 0.01, (***) P < 0.001, (****) P < 0.0001. ( F ) qRT-PCR analysis of the indicated miRNAs, relative to U6, in <t>NIH3T3</t> cells at time points after serum starvation and restimulation. NIH3T3 cells expressing dCas9-KRAB were infected with lentivirus encoding a nontargeting guide (sgNT) or guides targeting Plagl1 or Lrrc58 . Parental NIH3T3 cells were infected with lentivirus expressing Cas9 and a nontargeting guide (sgNT) or Zswim8- targeting guide (sg Zswim8 ). Values were normalized to expression at the 0 h time point for each condition. n = 3 technical replicates per condition, with mean ± SD shown.

Parental NIH3T3 cells were infected with lentivirus expressing Cas9 and a nontargeting guide (sgNT) or Zswim8- targeting guide (sg Zswim8 ). Values were normalized to expression at the 0 h time point for each condition. n = 3 technical replicates per condition, with mean ± SD shown. P -values were calculated by one-tailed Student's t -test comparing sg Plagl1 (dCas9-KRAB) or sg Lrrc58 (dCas9-KRAB) with sgNT (dCas9-KRAB) or comparing sg Zswim8 (Cas9) with sgNT (Cas9).

    Figure Lengend Snippet: ( A, B ) Immunofluorescence on serum-starved NIH3T3 cells. Cell nuclei are stained in blue by DAPI. Cells undergoing PCD are marked in red by CC3. The scale bars (in white) represent a length of 20 μm. ( A ) At least 650 cells per genotype and treatment were used for these measurements, pooled from three replicates. Data shown as mean ± s.e.m. Statistical evaluation was performed by using Kruskal-Wallis test with Dunn’s multiple comparisons test. Asterisks denote statistical significance ( Tctn +/+ vs. Tctn1 -/- : **** P = 0.0001; Tctn1 +/+ vs. Tctn1 -/- + DMSO: **** P <0.0001; Tctn1 -/- vs. Tctn1 -/- + SFN: **** P <0.0001; Tctn1 -/- + DMSO vs. Tctn1 -/- + SFN: **** P <0.0001). ns = not significant. ( B ) At least 790 cells per genotype and treatment were used for these measurements, pooled from three replicates. Data shown as mean ± s.e.m. Statistical evaluation was performed by using Kruskal-Wallis test with Dunn’s multiple comparisons test. Asterisks denote statistical significance ( Cep290 +/+ vs. Cep290 -/- : **** P <0.0001; Cep290 +/+ vs. Cep290 -/- + DMSO: **** P <0.0001; Cep290 -/- vs. Cep290 -/- + SFN: **** P <0.0001; Cep290 -/- + DMSO vs. Cep290 -/- + SFN: **** P <0.0001). ns = not significant. ( C ) TUNEL assay on control + DMSO ( n = 35), control + SFN ( n = 39), cep290 MO + DMSO ( n = 25) and cep290 MO + SFN ( n = 31) Xenopus embryos at stage 34, pooled from three replicates. Data shown as mean ± s.e.m. Statistical evaluation was performed by using two-tailed Mann-Whitney U test. Asterisks denote statistical significance (control + DMSO vs. cep290 MO + DMSO: **** P <0.0001; cep290 MO + DMSO vs. cep290 MO + SFN: **** P <0.0001). ns = not significant.

    Article Snippet: NIH3T3 cells (#ACC59) and HEK293 cells (#ACC35) were both purchased by the German Collection of Microorganisms and Cell Cultures GmbH (DSMZ).
