Acute myeloid leukemia is known as one of the most malignant diseases. We aimed at exploring the effect of portulacerebroside A (PCA) on the apoptosis in human leukemia HL60 cells and clarify the possible mechanisms involved in. By MTT analysis, we found that PCA (1-100μM) inhibited the cell viability in a time- and dose-dependent manner, and cell cycle was arrested at G0/G1 period. PCA treatment from 5 to 50 μM dose-dependently induced apoptosis from 12.7 ± 1.56% to 52.7 ± 6.214% of HL60 cells. Mitochondrial membrane potential (MMP) was decreased and reactiveoxygen species (ROS) accumulated obviously. mRNA expressions and protein levels of Bax/Bcl-2, caspase-3 and caspase-9 were elevated significantly. ERK1/2, JNK1/2 and p38 MAPK pathway were blocked detected by western blot analysis. In conclusion, PCA can act as a new agent for leucocythemia treatment.
