The tumor promoter TPA2 (12-O-tetradecanoylphorbol-13-acetate) has been shown to exhibit a radiomimetic activity on the cell cycle of HeLa cells (V. Kinzel, J. Richards, and M. Stöhr (1980) Science 210, 429). The response includes a delay of cells in G2 phase. The relation between TPA-induced release of arachidonic acid (AA) and the inhibition in G2 phase was studied. Exogenous AA (greater than 10(-4) M; in presence of 10% serum) is shown to delay HeLa cells in G2 and to enhance the effectiveness of TPA in this respect. The inhibition of the TPA-induced AA liberation by fluocinolone acetonide, however, does not influence the TPA-effected G2 delay. The diacylglycerols 1,2-dioctanoyl-glycerol and 1-oleoyl-2-acetylglycerol delay HeLa cells in G2 but without major stimulation of AA liberation. On the basis of the data it is concluded that AA released from HeLa cells due to the action of TPA is not involved in the TPA-induced delay of cells in G2 phase.
