| Summary: | Mitragyna speciosa Korth (Rubiaceae) is one of the medicinal plants used
traditionally to treat various types of diseases especially in Thailand and Malaysia.
Its anti-inflammatory and analgesic properties of its crude form are well documented.
In this study, the cellular mechanism involved in the anti-inflammatory effects of
mitragynine, the major bioactive constituent, was investigated. The effects of
mitragynine on the mRNA and protein expression of COX-1 and COX-2 and the
production of prostaglandin E2 (PGE2) were investigated in LPS-treated RAW264.7
macrophage cells. Quantitative RT-PCR was used to assess the mRNA expression of
COX-1 and COX-2. Protein expression of COX-1 and COX-2 were assessed using
Western blot analysis and the level of PGE2 production was quantified using
Parameter™ PGE2 Assay (R&D Systems). |
