| Abstract: | PGA1 and PGE1 reduced the plating efficiency and inhibited proliferation of Cloudman S-91 murine melanoma cells in a dose dependent manner, as assessed by their effects on colony formation in soft agar. PGF2α did not reduce plating efficiency but was as effective as PGA1 in raising cAMP and cGMP levels. This data suggests that the inhibition of Cloudman S-91 murine melanoma cell growth occurs via a non-cyclic nucleotide mechanism. |
