The heatmap showed differential expression of model-constructing genes between the high-risk and low-risk groups among the 4188 BC patients, where UBE2C and CALML5 were distinctly upregulated in the high-risk group, and CX3CR1, IFT74, and FABP4 showed the opposite trend (Figure 3C). Here, CX3CR1 is linked to breast cancer.
