Remarkably, mice that received the gemCelex (i.e., COX-2/PGE2 blockade) vaccination displayed a significantly heightened antitumoral response, with hindered tumor growth (Fig. 3g; p < 0.05 post 28 days) and engraftment (Fig. 3h; p < 0.0001 post 50 days). The gene discussed is PTGS2; the disease is neoplasm.
