In this paper, the effects of HMBA on the differentiation of human hepatocarcinoma cell line SMMC-7721 were investigated. After treated with 5 mmol/L HMBA, the proliferation of SMMC-7721 cells was inhibited remarkably, the cell growth inhibitory rate amounted to 64.14%, the cell mitotic index was declined by 53.88%. Light microscopy and transmission electron microscopy showed that the morphology and ultrastructure of the cells treated with HMBA undergone restorational alteration. Cytochemistry and immunocytochemistry assay revealed that the activities of gamma-GT declined and the levels of AFP and PCNA downregulated while the activity of TAT increased significantly after HMBA treatment. In the meantime, flow cytometry analysis showed that HMBA could arrest the cells in G0/G1 phase. The results showed that HMBA could effectively inhibit the proliferation, reverse the malignant morphology and ultrastructure, alter the levels of enzymes and antigens, arrest the cells in G0/G1, and induce the differentiation of human hepatocarcinoma SMMC-7721 cells in vitro.
