FN1 and cancer: Among these biological functions, the most significant class, cell movement, related to cancer cell migration and invasion was observed, in which, cathepsin B (CTSB), fibronectin (FN1), CD44 antigen (CD44), extracellular matrix protein 1 (ECM1), and protocadherin Fat 1 precursor (FAT1) previously shown to play an important role during the metastasis of other cancer cells[30] were included.
