We transfected mouse Nfia or Nfib promoter-driven luciferase constructs (pNfia-LUC or pNfib-LUC), or a control reporter plasmid into the NE-4C (mouse neuroepithelial cell line) and U251 MG (human glioma cell line) cell lines. The gene discussed is NFIB; the disease is central nervous system cancer.
