β-拉帕醌对胃癌细胞生长与侵袭的抑制作用及机制
Inhibitory effects of β-lapachone on the growth and invasion in gastric cancer cells
摘要
Abstract
Purpose To investigate the effects ofβ-1apachone on inhibition of pro1iferation and migration and induction of apoptosis in gastric cancer ce11s in vitro. Methods The ce11 viabi1ity was detected using MTT and co1ony formation assay,the migration abi1ity was determined using scratch assay method,and the apoptosis was examined using f1ow cytometry. Meanwhi1e,the expression of biomarkers of pro1iferation,EMT markers andapoptosiswere detected using Western b1ot ana1ysis. Results β-1apachone cou1d significant1y inhibit the pro1iferation of SGC-7901 and AGS gastric cancer ce11s( P<0. 05),and down-regu1ate the expression 1eve1s of Skp2 and DEK pro-teins. β-1apachonecou1d a1so inhibited the invasion and moti1ity of gastric cancer ce11s via down-regu1ating the expression 1eve1s of MMP-2/9 and Ezrin proteins and up-regu1ating the epithe1ia1 markers. In addition,β-1apachone enhanced the apoptosis of gastric canc-er ce11s,down-regu1ation of BCL-2/Bax ratio and up-regu1ation of activated Caspase-3/8/9. Conclusions β-1apachone can effective1y inhibit the pro1iferation and induce the apoptosis of gastric cancer ce11s,and inhibit the migration of gastric cancer ce11s via MMPs and EMT pathways.关键词
