H2AX and cancer: When DNA DSBs occur, phosphorylated H2AX (γ‐H2AX) rapidly forms large aggregates in cells.[24] Therefore, we assessed levels of DSB and γ‐H2AX levels in cancer cells using immunofluorescence staining through CLSM and FCM analysis, respectively (Figure 2M,N and Figure S9A,B, Supporting Information).
