Effects of small molecules on the DNA damage response pathway. (A) Representative images from γ-H2AX immunofluorescence to assess DNA damage in DM1 myotubes upon treatment with 2, 3, or bleomycin A5. (B) Quantification of the number of γ-H2AX foci/nucleus. Error bars represent SD; n = 3 biological replicates, with 40 nuclei counted per replicate; ***P < 0.001 (one-way ANOVA).
