Differential metabolism of dihomo-gamma-linolenic acid and arachidonic acid by cyclo-oxygenase-1 and cyclo-oxygenase-2: implications for cellular synthesis of prostaglandin E1 and prostaglandin E2.
Prostaglandin (PG) E(1) has been shown to possess anti-inflammatory properties and to modulate vascular reactivity. These activities are sometimes distinct from those of PGE(2), suggesting that endogenously produced PGE(1) may have some beneficial therapeutic effects compared with PGE(2). Increasing the endogenous formation of PGE(1) requires optimization of two separate processes, namely, enri...
متن کاملEvaluation of cytotoxicity mechanism of two cyclo-oxygenase-2 inhibitors in leukemia cell line
Introduction: Leukemia is considered one of the main causes of death, and current chemotherapeutic agents are unable to provide optimal responses due to chemo-resistance. Therefore, there is a constant need for new drugs. Cyclooxygenase- 2 (COX-2) inhibitors can be helpful by reducing the necessary dose of routine chemotherapeutic drugs. Herein, we evaluated the cytotoxicity activity as well...
متن کاملImmunoexpression of constitutive and inducible cyclo-oxygenase isoforms in the rat foetal and maternal digestive tract.
Cyclo-oxygenase (COX), which catalyses the conversion of arachidonic acid to prostaglandin endoperoxide and prostanoids, is widely expressed in mammalian organs. The aim of the study was to evaluate the immunoexpression of the constitutive and inducible cyclo-oxygenase isoforms (COX-1 and COX-2 respectively) in the oesophagus, stomach and the small and large bowels of untreated rat dams and foe...
متن کاملAsthma relieved by aspirin and by other cyclo-oxygenase inhibitors.
A 62-year-old man had been well until 10 years previously when he experienced a first attack of dry cough. Coughing continued and four years before admission, after a flu-like illness, attacks of breathlessness and wheezing began to occur. Though treated with bronchodilators and prednisone he noticed that asprin relieved his symptoms and began to take it regularly. The frequency and severity of...
متن کاملUtility of immunohistochemical analysis for cyclo-oxygenase 2 in the differential diagnosis of osteoblastoma and osteosarcoma.
AIMS To study the immunoexpression of cyclo-oxygenase (COX) 2 in osteoblastomas (OBs) and osteosarcomas (OSs), and to assess the utility of immunohistochemical analysis for COX 2 in the differential diagnosis of the two tumour forms. METHODS The immunohistochemical features of COX 2 were studied in 11 OBs and 30 OSs, including 26 high-grade OSs (16 osteoblastic, 7 chondroblastic, and 3 fibrob...
