The most significant pathways as for p-value were ErbB signaling pathway, MAPK signaling pathway, focal adhesion, PI3K-Akt signaling pathway, etc.; the most protein enriched pathways were PI3K-Akt signaling pathway, MAPK signaling pathway, ErbB signaling pathway, etc. From all the above, ErbB signaling pathway, PI3K-Akt signaling pathway, and MAPK signaling pathway were closely related with BCP or cancer and have been studied a lot. This evidence concerns the gene EGFR and cancer.
