ABSTRACT
Objective:
Compare the anti-tumor effect and mechanism of Liushenwan and realgar (As4S4) on human endometrial cancer cells JEC.Method:
The release of As in Liushenwan and As4S4 was measured by atomic absorption spectrometry. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used for cell proliferation, and cell migration was measured by Transwell assay. Flow cytometry and Western Blot were used to determine apoptosis and DNA damage.Result:
The dissolution of As in Liushenwan was 17.4%, and that of As4S4 was only 1.6% according to atomic absorption assay. With the same content of As, compared with the As4S4 group, the cell viability in the 3,10 mg·L-1 Liushenwan groups was decreased (P<0.05), the early apoptosis rate was significantly increased in 0.25,0.5,1 mg·L-1 Liushenwan groups (P<0.05), the rate of cell migration was decreased in 1 mg·L-1 Liushenwan group (P<0.05), the expressions of cleaved cysteinyl aspartate-specific proteinase-3 (cleaved Caspase-3), cleaved cysteinyl aspartate-specific proteinase-7 (cleaved Caspase-7), cleaved poly ADP-ribose polymerase (cleaved PARP), phosphorylated histone (p-H2AX), phosphorylation of checkpoint kinase 2 (p-CHK2) and ataxia-telangiectasia mutated (ATM) were increased in 1 mg·L-1 Liushenwan group (P<0.05), while the expression of phosphorylation of ataxia-telangiectasia mutated rad3-related (ATR) was decreased in 1 mg·L-1 Liushenwan group (P<0.05), with no significant changes in the expressions of cysteinyl aspartate-specific proteinase-3 (Caspase-3) and cysteinyl aspartate-specific proteinase-7 (Caspase-7).Conclusion:
With the same content of As, both Liushenwan and As4S4 could inhibit JEC cell proliferation and migration, and induce cell apoptosis and DNA damage. Liushenwan has a stronger effect than As4S4. It is suggested that there are other components in Liushenwan with an anti-tumor effect in cooperation with As.
