1 We previously reported that nicotine promoted gastric cancer cell growth via upregulation of cyclooxygenase 2 (COX-2). Nicotine prostaglandin-endoperoxide synthase 2 Homo sapiens
2 We previously reported that nicotine promoted gastric cancer cell growth via upregulation of cyclooxygenase 2 (COX-2). Nicotine prostaglandin-endoperoxide synthase 2 Homo sapiens
3 Inhibition of PKC by staurosporine attenuated nicotine-induced ERK1/2 phosphorylation and COX-2 expression. Nicotine prostaglandin-endoperoxide synthase 2 Homo sapiens
4 Furthermore, atenolol and ICI 118,551, a beta1- and beta2-adrenoceptor antagonist, respectively, reversed the stimulatory action of nicotine on the expression of PKC, ERK1/2 phosphorylation, and COX-2 together with cell proliferation. Nicotine prostaglandin-endoperoxide synthase 2 Homo sapiens
5 Collectively, these results suggest that nicotine stimulates gastric cancer cell growth through the activation of beta-adrenoceptors and the downstream PKC-betaI/ERK1/2/COX-2 pathway. Nicotine prostaglandin-endoperoxide synthase 2 Homo sapiens
