doi: 10.1101/2025.11.28.691009

Figure Lengend Snippet: A. c-NHEJ at dysfunctional telomeres with and without overhang. Functional telomeres are formed by a repetitive array of TTAGGG repeats ending with a long (50-300 nt) 3’ overhang bound by the shelterin complex (TRF1, TRF2, RAP1, TIN2, TTP1, POT1). At newly replicated leading end telomeres the overhang is formed by the Exonuclease APOLLO. In the absence of TRF2, telomeres still retaining their overhang are fused by c-NHEJ (top). In the absence of APOLLO and RAP1, the blunt telomeres resulting from replication cannot be resected and are fused by c-NHEJ (bottom). B. Immunoblot for TRF2 deletion, CHK2 phosphorylation as indication of ATM activation and actin as loading control in Ercc6l2 +/+ and Ercc6l2 -/- MEFs 108 h after transduction with single guide RNA (sgRNA) targeting Trf2 (sgTrf2). C. Representative FISH of metaphase spreads of Ercc6l2 positive and negative 108 h after Trf2 deletion. Telomeres were detected with Cy3-(TTAGGG)3 (green) and DNA was stained with DAPI (magenta). Green arrows highlight chromosome-type fusions. D. Quantification of telomeres involved in chromosome fusions per metaphase after deletion of Trf2 as in (B-C). Data from 3 independent experiments, 10 metaphases per experiment (n = 30 total), with median. E. Immunoblot for Rap1 deletion, CHK2 and actin in Ercc6l2 +/+ and Ercc6l2 -/- MEFs 120 h after transduction with single guide RNA (sgRNA) targeting Rap1 (sgRAp1) and/or Apollo (sgApollo). F. Representative FISH of metaphase spreads of Ercc6l2 positive and negative MEFs 120 h after Apollo and Rap1 deletion. Telomeres were detected with Cy3-(TTAGGG)3 (green) and DNA was stained with DAPI (magenta). Green arrows highlight chromosome-type fusions. White arrows highlight chromatid-type fusions. G. Quantification of telomeres involved in chromosome fusions per metaphase after deletion of Rap1 and Apollo as in (e-f). Data from 2 (no sgRNAs) or 3 (sgRap1 + sgApollo) independent experiments, 10 metaphases per experiment with median. Ordinary one-way analysis of variance (ANOVA). *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001, ****P ≤ 0.0001; ns, not significant.
