Abstract:
Objective To investigate the effect and mechanism of octreotide with or without wortmannin on the growth of gastric carcinoma cell BGC-823.Methods From June to August of 2007,in Remin Hospital of Wuhan University,cells were exposed to octreotide for four dilution(10-5、10-4、10-3、10-2g/L)with or without wortmannin(a special inhibitor of PI3'K/Akt pathway,the dilution is 40 nmol/L).And then the cytotoxicity was assessed by determining cell survival with MTT after 24 hours,with also were exposed to octreotide for the dilution of 10-3 g/L with or without Wortmannin in 12 h,24 h,36 h,48 h,then the cell survivral rate was accounted and the results were formulated in a table,and the cell cycle was checked-out with Flow Cytometer(FCM);the expression level of p27 gene and protein was determinated with RT-PCR and Western-bloting Test.Results The five groups within one reagent treating were compared with control group,and the results had difference,but the combination of two reagents group had significant difference(P
