HCC1937 cells show increased levels of APE1 and NPM1 proteins compared to HCC70 cells. Representative western blotting on whole cell extracts of TNBC cells shows the amount of APE1 (a, b) and NPM1 (c, d) proteins. On the right side of each panel, the Molecular Weights (MW), expressed in kDa, are indicated. On the left side of each panel, specific antibodies used in the immunoblotting are indicated. Relative graphs (b, d) report the difference of each protein, normalized on Actin, between the HCC70 (blue bar) and HCC1937 (red bar) cell lines. **p < 0.01, ****p < 0.0001
