NFKB1 and non-small cell lung carcinoma: Ginsenoside Rg3 can inhibit the activation of NF‐κB, the phosphorylation of IκB protein and the expression of NF‐κB regulated gene products (promotes apoptosis, cyclin‐D1, cyclin‐2, cyclooxygenase‐2, and VEGF) by targeting the NF‐κB pathway, sensitizing human NSCLC cells to γ radiation.190
