Tumor cell interaction with the endothelium of the vessel wall is a rate limiting step in metastasis. The fatty acid modulation of this interaction was investigated in low (LM) and high (HM) metastatic B16 amelanotic melanoma (B16a) cells. 12(S)-HETE increased the adhesion of LM cells to endothelium derived from pulmonary microvessels. All other monohydroxy and dihydroxy fatty acids were ineffective. LTB4 induced a modest stimulation but LTC4, LTD4, LTE4 as well as LXA4 and LXB4 were ineffective. The 12(S)-HETE enhanced adhesion of B16a cells was inhibited by pretreatment with 13(S)-HODE but not by 13(R)-, 9(S)-HODE or 13-OXO-ODE. 13(S)-HODE decreased adhesion of HM B16a cells to endothelium. 12(S)-HETE enhanced surface expression of integrin alpha IIb beta 3 and monoclonal antibodies against this integrin but not against alpha 5 beta 1, blocked enhanced but not basal adhesion to endothelium. Intravenous injection of 12(S)-HETE treated LM cells resulted in increased lung colonization (experimental metastasis). This effect was specific for 12(S)-HETE and was inhibited by 13(S)-HODE but not by other HODE's. 12(S)-HETE also enhanced lung colonization by HM cells and 13(S)-HODE decreased lung colonization by HM cells. Our results suggest a highly specific bidirectional modulation of metastatic phenotype and lung colonization by 12(S)-HETE and 13(S)-HODE.
