Effects of polydatin on the cell proliferation, migration, invasion and tumor growth of AML
To investigate the effects of polydatin (PD) on cell proliferation, migration, invasion and tumor growth of acute myeloid leukemia (AML).
METHODS
2
Human AML cell KG-1 were divided into normal group, PD low-, medium- and high-concentration groups (10, 30, 60 μmol/L PD), SQ22536 group [cyclic adenosine monophosphate (cAMP) inhibitor, 100 μmol/L], high concentration of PD+SQ22536 group (60 μmol/L PD+100 μmol/L SQ22536). The effects of PD on cell activity, apoptotic rate, invasion and migration ability, cAMP level, the expression of epithelial-mesenchymal transition (EMT) related proteins and protein kinase A (PKA) were investigated. Using BALB/c nude mice as subjects, a transplanted tumor model of AML nude mice was induced by subcutaneous inoculation of KG-1 cell suspension and then divided into control group, PD group, SQ22536 group and PD+SQ22536 group (with 6 mice in each group). The effects of PD on tumor volume and mass were measured.
RESULTS
2
Compared with the normal group or control group, the cell viabilities, the number of migrating cells, the number of invasive cells, the relative expressions of vimentin and Snail as well as the tumor volume and mass were decreased significantly in PD groups, while the apoptotic rates, cAMP levels, the relative expressions of E-cadherin and PKA were significantly increased, with a dose-dependent manner (
P
<0.05). SQ22536 had opposite effects on cells and nude mice compared to PD, and could significantly reverse the anti-tumor activity of PD (
P
<0.05).
CONCLUSIONS
2
PD may inhibit the proliferation, migration, invasion and EMT process of KG-1 cells, induce apoptosis, and inhibit tumor growth, by activating the cAMP/PKA signaling pathway, thereby exerting anti-AML effects.
