To further detect whether the effect of ML385 on lung cancer cell proliferation is mediated by inhibiting the KEAP1/NRF2 pathway, the expression of NRF2 and its target genes HO-1, GCLC and NQO1 in lung cancer cell lines treated with ML385 were investigated by western blot and real-time PCR. The gene discussed is NFE2L2; the disease is lung cancer.
