    Abstract:
    Decitabine is a synthesized cytosine analog that is a potent inhibitor of DNA methylation. There have been a few reports on the in vitro anti-melanoma effect of decitabine or its functional mechanisms. We investigated the anti-proliferation effect of decitabine on the cultured murine melanoma cell line K1735M2. MTT assay showed that decitabine had strong inhibition on melanoma K1735M2 in a time- and dose-dependent manner in vitro. Morphological observation showed that decitabine could induce melanoma K1735M2 cells to produce dendrite-like structures with the increase of decitabine concentration and incubation time. Decitabine could effectively induce K1735M2 cells to differentiate in vitro. Additionally, decitabine could induce a dose-dependent G2/M cell cycle arrest in K1735M2 cells. We provided experimental evidences that the anti-proliferation effect of decitabine on murine K1735M2 melanoma cells was associated predominately with G2/M cell cycle arrest and the induction of differentiation rather than apopotosis.
