1 Change in nicotine-induced VEGF, PGE2 AND COX-2 expression following COX inhibition in human oral squamous cancer. Nicotine mitochondrially encoded cytochrome c oxidase II Homo sapiens
2 We found that exposure of BHY cells to nicotine (200 microg/mL for 6 hours) resulted in 2.9-fold induction of COX-2 expression as well as a 4-fold increase in VEGF levels compared with a control group. Nicotine mitochondrially encoded cytochrome c oxidase II Homo sapiens
3 Pretreatment with celecoxib inhibited nicotine-induced change in the expression of VEGF and COX-2. Nicotine mitochondrially encoded cytochrome c oxidase II Homo sapiens
4 The results suggest that stimulation of COX-2 and VEGF expression can contribute as important factors in the tumorigenic action of nicotine in oral cancer progression. Nicotine mitochondrially encoded cytochrome c oxidase II Homo sapiens
