WebE4F1-depletion impacts on ATM/ATR-CHK1 signaling in response to CT drugs Gemcitabine and Cisplatin. (A)—ShRNA-mediated depletion of E4F1 in SUM159 TNBC cells impacts on CHK1 protein level and on the S 345 phosphorylation of CHK1 by ATM/ATR in response to Gemcitabine and Cisplatin. This effect was reversed by the co-expression of the shRNA ...
