In addition, given that MYOF is overexpressed in multiple types of epithelial cancers, including breast adenocarcinoma [17], ductal pancreatic adenocarcinoma [33], non-small cell lung adenocarcinoma [17, 34], squamous cell carcinoma [14], hepatocellular carcinoma [11], and melanoma [35], we suggest that MYOF will be a substantial participant in the transition from a stable parenchymal cell in epithelia to a premetastatic and then completely metastatic cell that invades and disseminates to distant organs to form secondary tumors. This evidence concerns the gene MYOF and squamous cell carcinoma.
