ANOVA = analysis of variance; HCC = hepatocellular carcinoma; RMS = root mean square; SEM = standard error of the mean; TTFields = Tumor Treating Fields.
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. Similar, the graphs illustrating the LC3 expression are not in a proper fit with the images shown in Figure 4D.
