Objective: To investigate the effect of Tetrastigma Hemsleyani Radix flavone (THRF) on proliferation
migration
invasion and Notch1 in esophageal cancer (EC) 9706 cells
and discuss its possible anti-esophageal cancer mechanism.Method: The EC9706 cells were cultured in vitro and treated with THRF with different concentrations(0.5~20 g·L-1)
with no THRF in blank group
and with MW 167 in positive control group. The 50% inhibitory concentration (IC50) was measured by cell counting kit-8 (CCK-8). The effect of THRF on adhesion rate was detected by the cell adhesion assay. The cell migration ability were evaluated by the wound healing assay. The cell invasion ability were evaluated by the transwell chamber assay. The expression of Notch1 and Notch1 mRNA expressions were detected by immunocytochemical analysis and Real-time PCR assay.Result: THRF can significantly increase the inhibition rate of EC9706 cells
with statistically significant difference compared with blank group (P<0.05
P<0.01). THRF can significantly inhibit the adhesion rate
the migration ability
the invasion cells
Notch1 positive cell rate and Notch1 mRNA expressions
with statistically significant difference compared with blank group (P<0.05
P<0.01).Conclusion: THRF can inhibit the EC9706 cells viability
migration and invasion ability
its mechanism for anti-esophageal cancer may be correlated with down-regulation of Notch1.
