XIAO Chan-chan, CHEN Mao-jian, MEI Fan-biao, et al. Effect and Mechanism of Capsaicin on Migration and Invasion of Hepatoma SMMC-7721 Cells[J]. Chinese journal of experimental traditional medical formulae, 2018, 24(18): 124-129. DOI: 10.13422/j.cnki.syfjx.20181718.
Objective: To investigate the effects of capsaicin on the migration and invasion of hepatoma SMMC-7721 cells and explore its possible molecular mechanism. Method: Different concentrations of capsaicin groups and blank group were established
and the cell viability was detected by cell counting kit-8 method 24 h after capsaicin (0

100 μmol·L-1) on cell migration and invasion ability of SMMC-7721 cells was detected by transwell. Western blot analysis was used to detect the protein expression levels of E-cadherin
Vimentin
matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9(MMP-9) in cells treated with capsaicin(0

capsaicin(25

100 μmol·L-1)had no significant effect on cell survival rates after 24 h
and starting from 150 μmol·L-1
the cell survival rate was gradually decreased as the concentration of capsaicin was gradually increased (P<0.01)
showing a dose-dependent effect. As compared with the blank group
capsaicin(50
75
100 μmol·L-1)intervention significantly inhibited migration and invasion of hepatoma SMMC-7721 cells in a concentration-dependent manner (P<0.01). As compared with the blank control group
capsaicin(50
75
100 μmol·L-1)intervention significantly up-regulated the E-cadherin protein expression level in SMMC-7721 cells (P<0.01)
down-regulated Vimentin
MMP-2 and MMP-9 protein expression levels (P<0.01). Conclusion: Capsaicin can inhibit the migration and invasion of hepatoma SMMC-7721 cells
and the mechanism may be related to up-regulating the expression of E-cadherin and down-regulating the expressions of Vimentin
