Moreover, conjugation of GNPs with cancer therapeutic agents, such as snake venom protein toxin NKCT1 (purified Naja kaouthia protein toxin) [110], chloroquine [111], and tumor necrosis factor-related apoptosis-inducing ligand [112], enhanced anticancer activity of these drugs in various kinds of cancer cells by inducing autophagic cell death, providing potential chemotherapeutic strategies for cancer treatment. The gene discussed is TNF; the disease is cancer.
