By including two different HCC cohorts (TCGA (LIHC) and Roessler et al. [30]) we found in each cohort a strong and highly significant correlation between HELLS and FOXM1 transcript levels (r = 0.89, p ≤ 0.001 and r = 0.64 p ≤ 0.001), as shown in Figure 7A and Figure S6A. This evidence concerns the gene FOXM1 and hepatocellular carcinoma.
