Fig. 6. Resection by MRE11 is required for SLFN11 to be recruited on chromatin.
A Immunoblots of chromatin-bound fractions prepared from TOV-112D (SLFN11-KO) cells treated with 10 μM olaparib and with or without 50 μM mirin for 0, 6, or 12 h. Blots were probed with the indicated antibodies. B Quantification of data from A. Data were normalized to untreated cells (0 h). Data are means ± standard deviations (n = 3–4, biological replicates). C Representative immunoblots of chromatin-bound fractions prepared from TOV-112D (parent) treated with 10 μM olaparib with or without 50 μM mirin for 0, 6, or 12 h. Blots were probed with the indicated antibodies. D Quantification of data from C. Data were normalized to untreated cells (0 h). Data are means ± standard deviations (n = 3–4, biological replicates). E Immunoblots of whole cell lysates prepared from the indicated TOV-112D cells: siCON or MRE11 siRNA (siMRE11). Blots were probed with the indicated antibodies. F Representative immunoblots of chromatin-bound fractions prepared from TOV-112D (parent) treated with 10 μM olaparib for 0, 6, or 12 h. Blots were probed with the indicated antibodies. G Quantification of data from F. Data were normalized to untreated cells (0 h). Data are means ± standard deviations (n = 7, biological replicates). H Representative immunoblots of whole cell lysates from parent TOV-112D cells treated with 10 μM etoposide or 10 μM olaparib for 0, 3, or 6 h. Blots were probed with the indicated antibodies. I Immunoblots of whole cell lysates prepared from the indicated TOV-112D cells: siCON or CtIP siRNA (siCtIP). Blots were probed with the indicated antibodies. J Representative immunoblots of chromatin-bound fractions prepared from TOV-112D (parent) treated with 10 μM olaparib for 0, 6, or 12 h. Blots were probed with the indicated antibodies. K Quantification of data from J. Data were normalized to untreated cells (0 h). Data are means ± standard deviations (n = 5, biological replicates). NS not significant, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 (one-way analysis of variance with Tukey’s post-hoc multiple comparisons test).
