1 Phosphoinositide-3-kinase (PI3K)/Akt, survivin, bcl-2 were significantly downregulated in cells treated with the combination of celecoxib and cisplatin, and decreased survivin and bcl-2 levels were found in cells with wortmannin, a specific PI3K inhibitor. Celecoxib BCL2 apoptosis regulator Homo sapiens
2 Phosphoinositide-3-kinase (PI3K)/Akt, survivin, bcl-2 were significantly downregulated in cells treated with the combination of celecoxib and cisplatin, and decreased survivin and bcl-2 levels were found in cells with wortmannin, a specific PI3K inhibitor. Celecoxib BCL2 apoptosis regulator Homo sapiens
3 Therefore, celecoxib exerts its anti-tumor activities through COX-2-independent mechanisms, which may be PI3K/Akt-dependent, and survivin and bcl-2-related. Celecoxib BCL2 apoptosis regulator Homo sapiens
4 PI3K may be at the center of the celecoxib effects, which play an essential role in the regulation of survivin and Bcl-2. Celecoxib BCL2 apoptosis regulator Homo sapiens
