Heme oxygenase (EC 1.14.99.3) is the rate-limiting enzyme in heme catabolism. Several lines of evidence suggest a possible role for heme oxygenase in the inflammatory process and in cellular signaling. We have evaluated the regulation of heme oxygenase-1 mRNA induction by the inflammatory stimuli, phorbol 12,13-myristate acetate, heat shock and interleukin-1 beta in cultured rat mesangial cells. Phorbol 12,13-myristate acetate and heat shock rapidly (maximal at 2-3 hrs) induced heme oxygenase-1 mRNA. The effect of interleukin-1 beta on heme oxygenase-1 mRNA induction was slower (maximal at 12 hrs) and modest. However, in the presence of a cyclooxygenase inhibitor, indomethacin, interleukin-1 beta strongly induced heme oxygenase-1 mRNA. The addition of exogenous PGE2 reversed the effect of indomethacin. These data suggest that pro-inflammatory stimuli increase heme oxygenase-1 mRNA expression in rat mesangial cells and that interleukin-1 beta-induced heme oxygenase-1 mRNA level is negatively modulated by PGE2.

It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES. Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin
D007375 Interleukin-1 A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.
