However, a mutation in the gene responsible forcell growth can result in amplification of cell growth signals dueto fast heterodimerization of epidermal growth factor receptors (EGFR),which can cause enhanced cell growth and lead to cancer.404−406 This trend can be controlled by stopping the growth signal throughtransfection of the cell with a competitive synthetic EGFR membrane-activepeptide (EGFR-MAB) for fake heterodimerization. The gene discussed is EGFR; the disease is cancer.
