- Abstract:
- Production of the osteolytic arachidonic acid metabolites, prostaglandin (PG) E2, PGI2 and PGF2 alpha, by neonatal mouse calvariae was quantitated by gas chromatography/mass spectrometry. Mouse recombinant interleukin 1 (rIL-1) raised medium levels of PGE2 and PGI2 (measured as 6-keto-PGF1 alpha) in the dose range tested (1.0-10.0 U/ml culture medium), while an effect on PGF2 was only observed at 10 U/ml. Bone resorption in response to rIL-1 reached a plateau at 3.0 U/ml. Mouse recombinant gamma-interferon (rIFN-gamma) between 100-500 U/ml suppressed basal PG synthesis and spontaneous resorption of cultured bone. In addition, IFN-gamma at 100 U/ml prevented stimulation of PG synthesis by 3.0 U/ml rIL-1 and thereby reduced the bone resorbing activity of the cytokine by at least 60%. 5 X 10(-7) M indomethacin was equally effective in suppression of PG synthesis and bone resorption. The present study provides evidence that IFN-gamma inhibits PG synthesis and consequently resorption of cultured bone.
