Abstract: AIM:To design to investigate the effects of tubeimoside on adhesion, invasion and migration of PGCL3 cells .METHODS :The cells grow inhibition me- diated by tubeimoside was measured by MTT assay after treatment with tubeimoside .The effects of tubeimoside on adhesion, invasion and migration of PGCL3 cells were de- termined using analysis of adhesion-related basement membrane components fibronectin and laminin, reconsti- tuted basement membrane invasion assay, and Transwell model, respectively .RESULTS:Tubeimoside displayed growth inhibitory activity against PGCL3 cells with IC50 values of 16 .77, 14 .62, and 14 .46 μmol·L -1 for 24, 48, 72 hours of tubeimoside treatment .1 .25, 2 .50 and 5 .00 μmol·L-1 of tubeimoside inhibited PGCL3 cells to invade the reconstituted basement membrane by 20 .6 %, 30 .6 %, 46 .8 %, and decreased the percentages of loco- motion and migration of PGCL3 cells by 14 .2 %, 24 .7 %, 42 .5 %, respectively .In addition, tubeimoside inhibited PGCL3 cells to adhere to the basement mem- brane components fibronectin and laminin, and inhibited the activity of type IV collagenase and its secretion by PGCL3 cells in a dose-dependant manner.CONCLU- SION:Tubeimoside can significantly inhibit the adhe- sion, invasion and migration of PGCL3 cells, and the sup- pression of adhesion of PGCL3 cells to fibronectin and laminin and of secretion and activity of type IV collage- nase in PGCL3 cells mediated by tubeimoside may be re- sponsible for the inhibition of adhesion and invasion of PGCL3 cells .

Key words: tubeimoside , adhesion , invasion , mi- gration , type IV collagenase, PGCL3 cells
