Celecoxib 24-33 tumor protein p53 Homo sapiens 98-101 19706164-6 2009 We investigated whether the anti-glioblastoma responses of celecoxib were p53-dependent, and whether celecoxib induced DNA damage leading to p53-dependent G1 cell cycle arrest, followed by autophagy or apoptosis. Celecoxib 101-110 tumor protein p53 Homo sapiens 141-144 19706164-8 2009 Inhibition of functional p53 in glioblastoma cells significantly reduced the anti-proliferative effect of celecoxib. Celecoxib 106-115 tumor protein p53 Homo sapiens 25-28 19706164-9 2009 In U87MG cells, celecoxib (8 and 30 muM) significantly induced DNA damage and inhibited DNA synthesis, corresponding with p53 activation. Celecoxib 16-25 tumor protein p53 Homo sapiens 122-125 19706164-16 2009 CONCLUSION: Our findings reveal that p53 increases human glioblastoma sensitivity to celecoxib. Celecoxib 85-94 tumor protein p53 Homo sapiens 37-40 19706164-17 2009 Celecoxib inhibits glioblastoma cell viability by induction of DNA damage, leading to p53-dependent G1 cell cycle arrest and p53-dependent autophagy, but not apoptosis. Celecoxib 0-9 tumor protein p53 Homo sapiens 86-89 19706164-17 2009 Celecoxib inhibits glioblastoma cell viability by induction of DNA damage, leading to p53-dependent G1 cell cycle arrest and p53-dependent autophagy, but not apoptosis. Celecoxib 0-9 tumor protein p53 Homo sapiens 125-128
