Chen et al reported that codelivery 5‐FU with epidermal growth factor (EGF) grafted hollow mesoporous silica nanoparticles (EGF‐HMSNs) can augment cytotoxicity and reverse MDR by enhancing drug accumulation in tumor cells, inducing S phase arrest and inducing cell death in 5‐FU‐resistant SW480 cells.124. The gene discussed is EGF; the disease is neoplasm.
