1 We found that both PTH and IL-1 stimulated the release of PGE2 and 6-keto-PGF1 alpha (the stable metabolite of PGI2). Dinoprostone interleukin 1 complex Mus musculus
2 Moreover, IL-1 showed 2- to 3-fold greater efficacy than PTH in stimulating PGE2 release. Dinoprostone interleukin 1 complex Mus musculus
3 IL-1 (60 pM) and PTH (2.4 nM) stimulation of PGE2 production showed a similar time course, with a lag phase of 0.75-1.5 h. Cortisol (1-100 nM) reduced basal PGE2 production and calcium release. Dinoprostone interleukin 1 complex Mus musculus
4 In bones labeled with [3H]AA, IL-1 and PTH increased [3H]PGE2 and [3H]6-keto-PGF1 alpha release, as measured by HPLC and TLC. Dinoprostone interleukin 1 complex Mus musculus
5 mRNA was increased by both PTH and IL-1 to a similar extent despite the greater effect of IL-1 on PGE2 production. Dinoprostone interleukin 1 complex Mus musculus
