Abstract:
Objective To explore the effect of transcription factor SOX18 on proliferation, migration and invasion of HeLa cells and its related mechanism. Methods HeLa cells were divided into blank control group, negative control group, pCI-SOX18 group. The expression of SOX18 and matrix metalloproteinase 7 (MMP-7) was detected by Western blot. The cell proliferation of different group was measured by MTT analysis. The effect of transcription factor SOX18 on migration and invasion of HeLa cells were measured by Transwell assay. Results HeLa cells were successfully transfected with pCI-SOX18. According to the results of MTT analysis, the cell number of pCI-SOX18 group showed no significant difference compared with blank control group and negative control group (P> 0.05). Compared to blank control group (0.23 ±0.05) and negative control group (0.28±0.07), SOX18 expression in pCI-SOX18 group (1.16±0.13) was significantly higher (F=218.14, P<0.05). Meanwhile, MMP-7 expression in pCI-SOX18 group (0.95±0.09) was increased significantly compared with blank control group (0.71±0.07) and negative control group (0.68±0.06) (F=116.84, P < 0.05). The number of cell migration in pCI-SOX18 group (175.71 ±17.17) was increased significantly compared with that in negative control group (95.19 ±8.18) and that in blank control group (93.34±9.72) (t=75.47, t=77.35, P<0.05). Compared with that in negative control group (98.63±14.62) and that in blank control group (96.57 ±13.95), the number of cell invasion in pCI-SOX18 group (247.12 ±36.82) was significantly higher (t=98.02, t=99.34, P<0.05). Conclusion Overexpression of SOX18 has no effect on the proliferation of HeLa cells, but has a significant role in promoting cell migration and invasion probably by regulating MMP-7 expression positively.
