Abstract:

Salvianolic acid A (SAA), one of the main derivatives of Salvia miltiorrhiza, has been shown to possess anti-inflammatory and anti-thrombotic activities. Its role in inhibiting tumor growth, however, remains elusive. The aim of this study was to investigate the effect of SAA on acute myeloid leukemia (AML). Here, SAA showed a dose-dependent cell viability inhibition and apoptosis induction in AML cells. At the molecular level, SAA increased the expression of Bak and decreased the expression of Bcl-xL, following by PARP cleavage and caspase-3 activation. SAA also markedly attenuated Akt phosphorylation in AML cells. In a xenograft mouse model, SAA significantly suppressed the growth of AML tumors in vivo. Furthermore, SAA exhibited a more profound pro-apoptotic effect on primary AML cells than on bone marrow mononuclear cells from patients with benign diseases. Therefore, the pro-apoptotic and anti-tumor properties of SAA suggested its promising therapeutic value for AML.
