این تحقیق به منظور ارزیابی میزان فنل و فلاونویید کل، عملکرد آنتیاکسیدانی، اثر ضددردی و ضدالتهابی عصاره گیاه دارویی ریحان بنفش ( basillicum var. purpurescens.Ocymum) بر موشهای صحرایی نر در مقایسه با داروهای اپیوئیدی (مرفین) انجام گرفت. در این مطالعه از موشهای صحرایی نرنژاد ویستاردرمحدوده وزنی250±10 گرم استفاده گردید. بهصورت تصادفی موشها به پنچ گروه ده تایی تقسی...
Romanovsky, Andrej A., Andrei I. Ivanov, and Elena K. Karman. Blood-borne, albumin-bound prostaglandin E2 may be involved in fever. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1840–R1844, 1999.— Although the involvement of blood-borne PGE2 in fever has been hypothesized by several authors and has substantial experimental support, the current literature often rejects this hy...
• PGE2 signaling positively regulates hematopoietic stem cells both directly and via activation of a nonhematopoietic cell population. • EP4 is a major receptor for the PGE2-mediated regulation of hematopoietic stem and progenitor cells. Prostaglandin E2 (PGE2) regulates hematopoietic stem/progenitor cell (HSPC) activity. However, the receptor(s) responsible for PGE2 signaling remains unclear. ...
objective(s): inflammation is an immune response toward injuries. although inflammation is healing response, but in some condition it will lead to chronic disease such as rheumatoid arthritis, inflammatory bowel disease, atherosclerosis, alzheimer’s and various cancer. indonesian cassia (cinnamomum burmanni c. nees & t. ness) known to contain coumarin, is widely used for alternative medicine es...
Prostaglandin E2 (PGE2) promotes tumor-persistent inflammation, frequently resulting in cancer. Curcumin is a diphenolic turmeric that inhibits carcinogenesis and induces apoptosis. PGE2 inhibits curcumin-induced apoptosis; however, the underlying inhibitory mechanisms in colon cancer cells remain unknown. The aim of the present study is to investigate the survival role of PGE2 and whether addi...
PGE2 elevates IL-23 production in mouse dendritic cells while inhibits IL-23 production in isolated human monocytes. Whether this differential effect of PGE2 on IL-23 production is cell-type- or species-specific has not been investigated in detail. The present study was designed to investigate the effect of PGE2 on IL-23 production in human DCs and the possible underlying mechanisms. Human mono...
The effect of bacteria on the production of prostaglandin E2 (PGE2) and PGE2 metabolites by fetal membranes has been investigated. Live bacteria stimulated a large increase in the levels of PGE2 metabolites, but only a small increase in the levels of PGE2 on the fetal side of the membranes. No significant changes in the levels of PGE2 or its metabolites were found on the maternal side. Bacteria...
Transforming growth factor-ß1 (TGF-β1) is a multifunctional cytokine that is involved in various pathophysiological processes, including cancer progression and fibrotic disorders. Here, we show that treatment with TGF-β1 (5 ng/mL) induced downregulation of cyclooxygenase-2 (COX-2), leading to reduced synthesis of prostaglandin E2 (PGE2), in human lung cancer A549 cells. Treatment of cells with ...
The mammary gland, like most tissues, produces measurable amounts of prostaglandin E2 (PGE2), a metabolite of arachidonic acid produced by sequential actions of two cyclooxygenases (COX-1 and COX-2) and three terminal PGE synthases: microsomal prostaglandin E2 synthase-1 (mPGES1), mPGES2, and cytosolic prostaglandin E2 synthase (cPGES). High PGE2 levels and COX-2 overexpression are frequently d...
Skeletal muscles harbor quiescent muscle-specific stem cells (MuSCs) capable of tissue regeneration throughout life. Muscle injury precipitates a complex inflammatory response in which a multiplicity of cell types, cytokines, and growth factors participate. Here we show that Prostaglandin E2 (PGE2) is an inflammatory cytokine that directly targets MuSCs via the EP4 receptor, leading to MuSC exp...
