Dose-dependent increase in DNA double-strand breaks induced by THS
(a) Representative images of γ−H2AX foci staining 24 h after THS exposure across different doses. (b) Quantitation of γ-H2AX foci staining 24 h after THS exposure. Number of cells with more than five foci were counted. Significance was obtained using Chi-square test in comparison to control treated cells (** P-value<0.01).
