FOS and hepatocellular carcinoma: According to the results in Figures 2(a) and 2(b), a total of 6 transcription factors were identified by LASSO regression analysis, namely, DACH1, ASCL1, FOSB, FOS, EBF1, and GTF2H2. We divided HCC samples into the high-risk and low-risk groups and found that the number of surviving patients from the low-risk and high-risk groups gradually decreased, and the expressions of 6 DETFs were also different (Figure 2(c)).
