Subsequently, we narrowed down the candidate pathways by searching for the consistent pathways between TNBC vs. ER+ and TNBC vs. HER2+ cancer cells, which were predominantly involved in metabolic processes, including protein metabolic, nitrogen compound metabolic, macromolecule metabolic, nucleobase‐containing metabolic, and cellular metabolic processes (Figure 3C). Here, ERBB2 is linked to cancer.
