Response to Reviewer 1 Comments In this manuscript, the authors, Davidi et al have investigated the effect of TTFields in HCC cells and an animal model, alone or in combination with sorafenib.
Point 2: Despite the expression of cleaved PARP was very low in the tumors treated with TTFields or sorafenib alone (as shown in IHC-images in Figure 4F), the authors declare about ~ 20% of positive cells, as show in the graphs below IHC-staining.
