Figure 4. ATM is activated by spermidine in GM00637 cells.

Figure 4

GM00637 cells with or without KU55933 pretreatment (a,b), and GM05849 cells (c) were exposed to 50 μM spermidine or CCCP, followed by immunofluorescence analyses of total and p-ATM on Ser-1981. The scale bar is 10 μm. Ratios of cells expressing p-ATM Ser-1981 to cells expressing total ATM were presented (d). 20–45 cells/condition from three experiments were collected. Values are mean ± SD, *p < 0.05 vs. control.
