Figure 4. Inhibiting DNA replication blocks T-circle formation in MSK-41 RTEL1R1264H cells.
(A) Phi29-dependent T-circles in BJ hTERT and MSK-41. (B) Phi29-dependent T-circles in RTEL1 floxed/- MEFs ± Cre, BJ hTERT and MSK-41. (C) Phi29-dependent T-circles in BJ hTERT and MSK-41 ± aphidicolin (APD; 5 µM). (D) Dot blot of the Phi29-dependent T-circles in BJ hTERT and MSK-41 ± aphidicolin (APD; 5 µM). (E) Quantification of the fold increase in intensity of Phi29-dependent T-circles in the different cell lines subjected to the indicated treatments. Intensity mean and standard deviation were calculated over two independent experiments; statistical analysis (one-way ANOVA) was calculated with Prism (GraphPad).
