FN1 and metastatic neoplasm: More precisely, the metastatic EGFR interactome consisted of 34 proteins (Figure 5A), with 10 proteins (PTPN1, CTNNB1, CTNND1, YWHAZ, CD44, FN1, ITGB1, GADPH, ENO1, HSPA4) shared with non‐metastatic tumors (Figure 5B), while the remaining 24 proteins were uniquely present in metastatic tumors.
