Beside the c-MET and COX2 suppression, the microarray results also showed that OC treatment downregulated over 50% of CEACAM6, AKRC1, AKR1C3 and AKR1B10 expression in the A549 NSCLC tissues versus vehicle control-treated group. The gene discussed is CEACAM6; the disease is non-small cell lung carcinoma.
