We then selected some genes related to CAC, such as VEGFA, BRAF, Notch1, PIK3CA, NTRK1, PTEN, and EGFR. The clustering results showed that the expression patterns of tumor-related genes in the BD5115 group were more similar to that in the normal group without treatment than in the CAC group (Figure 6E). This evidence concerns the gene EGFR and neoplasm.
