Since an inverse relationship between the protein levels of OVOL2 and phosphorylated P65 was observed in NSCLC cell lines (Fig. 1A) and OVOL2 protein expression was decreased in P65-overexpressing cells (Fig. 3D), we speculated that P65 may regulate OVOL2 expression. The gene discussed is OVOL2; the disease is non-small cell lung carcinoma.
