N2 - Okadaic acid is a potent non-phorbol ester mouse skin tumor promoter. Unlike the phorbol ester tumor promoters, okadaic acid is unable to promote the induction of morphological transformation in Syrian hamster embryo cell colonies. On the contrary, okadaic acid seems to counteract the effect of phorbol esters on transformation. Also unlike phorbol ester tumor promoters, okadaic acid does not inhibit intercellular communication, neither in primary hamster embryo cells, nor in the phorbol ester sensitive cell line BPNi. Furthermore, okadaic acid has no effect on the reoccurrence of communication following removal of 12-O-tetradecanoylphorbol-13-acetate.
