EGCG nanoparticles (lecithin‐based and Poly (lactic‐co‐glycolic acid)‐based) showed superior anticancer activity compared to free EGCG in inhibiting lung cancer tumors in the PDX model by inhibiting NF‐κB activation and suppressing the expression of NF‐κB‐regulated genes (Zhang et al. 2020). Here, NFKB1 is linked to lung cancer.
