Abstract: | Objective To investigate the effects of rAdinbitor on the adhesion and proliferation of human hepatoma cell strain SMMC-7721.
Methods Cell adhesion assay was used to observe the effect of rAdinbitor on the adhesion of SMMC-7721 cells to fibronectin (FN). Crystal
violet staining was performed to detect the influence of rAdinbitor on the adhesion of SMMC-7721 cells. MTT assay was employed
to detect the inhibitory effects of different concentration of rAdinbitor on the proliferation of SMMC-7721 cells. The morphologic
changes of the control SMMC-7721 cells and the apoptotic cells induced by 200 μg/mL rAdinbitor for 36 h were observed under
light microscope after HE staining. Flow cytometry analysis was applied to determine the apoptosis rate of SMMC-7721 cells.
Results (1) FN promoted the adhesion of human hepatoma cell strain SMMC-7721 in a dose-dependent manner. (2) rAdinbitor could dose-dependently
inhibit the adhesion of SMMC-7721 cells to FN. The higher the concentration was, the stronger the inhibition was. There was
significant difference among the groups (P < 0.05). (3) rAdinbitor had a strong inhibition on the proliferation of SMMC-7721 cells and showed a dose-dependent manner
(P < 0.05). After a 48 h exposure, the IC50 value of rAdinbitor was 177.83 μg/mL. (4) After exposure of SMMC-7721 cells to 200 μg/mL rAdinbitor for 36 h, the early morphologic
changes appeared and the apoptosis rate was 20.68%, significantly higher than that of the control group (2.38%, P < 0.05).
Conclusion rAdinbitor can dose-dependently inhibit the SMMC-7721 cells adhesion to FN, and can inhibit the proliferation in dose-dependent
manner and promote their apoptosis. |
