The biological activity of Mastixia arborea (MA) relates to inflammation, but the underlying mechanisms are largely unknown. We confirmed the anti-inflammatory effects of a methanol extract of MA extract on lipopolysaccharide (LPS)-stimulated RAW264.7 mouse macrophage cells and carrageenan-induced mice paw edema. The MA extract significantly inhibited nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-1β (IL-1β), and IL-6 production in LPS-stimulated RAW264.7 cells. In vitro expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was suppressed by the extract. The extract attenuated acute inflammatory responses in carrageenan-induced mice paw edema. A mechanism study indicated that translocation of the NF-κB (p65) subunit into the nucleus and phosphorylation of ERK and JNK were inhibited by the extract. These results indicate that the extract is an effective suppressor of the inflammatory response, blocking the phosphorylation of ERK and JNK and the translocation of NF-κB in macrophages, thereby producing an anti-inflammatory effect in vivo.

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D009569 Nitric Oxide A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

D002351 Carrageenan A water-soluble extractive mixture of sulfated polysaccharides from RED ALGAE. Chief sources are the Irish moss CHONDRUS CRISPUS (Carrageen), and Gigartina stellata. It is used as a stabilizer, for suspending COCOA in chocolate manufacture, and to clarify BEVERAGES.

D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
D004487 Edema Abnormal fluid accumulation in TISSUES or body cavities. Most cases of edema are present under the SKIN in SUBCUTANEOUS TISSUE. Dropsy,Hydrops,Anasarca
D005260 Female Females
