FN1 and cancer: These data are in accordance with a data set from CC patients (Tables 2, 3), from the cancer genome atlas (TCGA) database (Cerami et al., 2012; Gao et al., 2013), where increased expression of Hh pathway genes (GLI1 and SMO) negatively correlates with protein expression of CDH1 (E-cadherin, epithelial marker) and positively correlate with CDH2 (N-Cadherin) and FN (Fibronectin), mesenchymal markers.
