Retinoids can block cell proliferation and induce apoptosis in tumor cells. The antitumoral effect of synthetic retinoids like Adapalene (ADA) on hepatoma cells (HepG2, Hep1B) was investigated. Cell proliferation was assessed by measuring DNA synthesis and apoptosis by flow cytometry and immunocytochemistry. Cell cycle- and apoptosis-associated proteins were semi-quantified by Western Blotting and breakdown of mitochondrial membrane potentials was detected by JC-1 staining. ADA at 10(-4)M efficiently induced apoptosis, reaching 61.7% in HepG2 and 79.1% in Hep1B after 72 h incubation. This was accompanied by up-regulation of pro-apoptotic bax and caspase 3, while bcl-2 was down-regulated, shifting the bax/bcl-2 ratio to >2.3 in hepatoma cells. ADA inhibits hepatoma cell growth in vitro and is a powerful inducer of hepatoma cell apoptosis.
