Abstract:
Objective To evaluate the effect of propofol on invasiveness of human gastric cancer MKN-45 cells.Methods Human gastric cancer cell line MKN-45 were seeded in culture plates.After being cultured for 24 h,the cells were randomly divided into 5 groups(n =12 each):control group (group C),intralipid group (group Ⅰ),4 μg/ml propofol group (group P1),8 μg/ml propofol group (group P2) and 16μg/ml propofol group (group P3).The cells were treated with 10％ intralipid and 4,8 and 16 μg/ml propofol for 24 h in I and P1-3 groups,respectively.The cells were then cultured for another 24 h.The migration of cells was determined by cell scratch test.The invasion of cells was determined by Transwell invasion assay.The expression of RhoA and ROCK1 was detected by Western blot.Results Compared with group C,the cell migration and invasion were significantly decreased,and the expression of RhoA and ROCK1 was down-regulated in P1-3 groups,and no significant changes were found in the parameters mentioned above in group Ⅰ.With the increasing concentrations of propofol,the cell migration and invasion were gradually decreased,and the expression of RhoA and ROCK1 was gradually down-regulated in P1-3 groups.Conclusion Propofol can inhibit the invasiveness of human gastric cancer MKN-45 cells cultured in vitro dose-dependently and inhibition of RhoA/ROCK1 signaling pathway may be involved in the mechanism.
