EGFR and carcinoma: At molecular level, transforming growth factor alpha (TGF-α) is expressed by carcinoma cells and this simultaneous expression of TGF-α and Epidermal Growth Factor Receptor (EGFR) by the carcinoma cells result in the proliferation of cells forming abnormal cancerous cells.14 Gene therapy that target specific genes concerned in the upregulation of cancer could be considered for cancer treatment in the near future.
