Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.
