In one study, functionalization of AgNPs with monoclonal antibodies targeting EGFR (AgNPs-Anti-EGFR) was investigated in human nasopharyngeal carcinoma epithelial (CNE) cells and found that AgNPs-Anti-EGFR inhibited cell growth, induced apoptosis, increased sensitivity to radiation, and decreased expression of DNA damage/repair proteins such as Ku-70, Ku-80, and Rad51. The gene discussed is EGFR; the disease is nasopharyngeal carcinoma.
