1 Arecoline-induced phosphorylated p53 and p21(WAF1) protein expression is dependent on ATM/ATR and phosphatidylinositol-3-kinase in clone-9 cells. Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
2 Betel-quid use is associated with liver cancer whereas its constituent arecoline is cytotoxic, genotoxic, and induces p53-dependent p21(WAF1) protein expression in Clone-9 cells (rat hepatocytes). Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
3 Thus, we studied the role of ATM/ATR and PI3K in arecoline-induced p53 and p21(WAF1) protein expression in Clone-9 cells. Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
4 Moreover, arecoline only increased the levels of the p-p53Ser6, p-p53Ser15, and p-p53Ser392 phosphorylated p53 isoforms among the known isoforms. Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
5 We conclude that arecoline activates the ATM/ATR-p53-p21(WAF1) and the PI3K/Akt-mTOR-p53 pathways in Clone-9 cells. Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
6 We conclude that arecoline activates the ATM/ATR-p53-p21(WAF1) and the PI3K/Akt-mTOR-p53 pathways in Clone-9 cells. Arecoline Wistar clone pR53P1 p53 pseudogene Rattus norvegicus
