We compared the gene expression patterns of control cells to those of NFE2L2 knockdown (KD) human lung cancer cells to identify genes potentially regulated by NFE2L2. One microarray dataset (GSE38332) containing gene expression information from both control and NFE2L2 KD A549 lung cancer cells21 was downloaded from the Gene Expression Omnibus (GEO) database22. The gene discussed is NFE2L2; the disease is lung carcinoma.
