Cyclooxygenase pathways.
This review compiles the current knowledge on the effects of prostanoids - arachidonic acid metabolites - on their own synthesis, activity and degradation. Interaction mechanisms between the receptors for the relevant compounds are presented, in particular with regard to the cooperation between a thromboxane A₂ and prostaglandin I₂ receptors. The questions of desensitization and internalization...
متن کاملThe Role of Cyclooxygenase-2 in Signaling Pathways Promoting Colorectal Cancer
Colorectal cancer is one of the most common cancers in the world. Various factors are involved in the development and progression of this disease. One of these agents is cyclooxygenase-2 (COX-2). COX-2 is a product of the PTGS2 gene and converts free arachidonic acid to prostaglandins. COX-2 is not naturally expressed in most normal cells. Noticeably, the increased expression of COX-2 has been ...
متن کاملCyclooxygenase inhibitors combined with deuterium-enriched water augment cytotoxicity in A549 lung cancer cell line via activation of apoptosis and MAPK pathways
Objective(s): Combination chemotherapy is a rational strategy to increase patient response and tolerability and to decrease adverse effects and drug resistance. Recently, the use of non-steroidal anti-inflammatory drugs (NSAIDs) has been reported to be associated with reduction in occurrence of a variety of cancers including lung cancer. On the other hand, growing evidences suggest that deuteri...
متن کاملCyclooxygenase-independent actions of cyclooxygenase inhibitors.
Several studies have demonstrated unequivocally that certain nonsteroidal anti-inflammatory drugs (NSAIDs) such as sodium salicylate, sulindac, ibuprofen, and flurbiprofen cause anti-inflammatory and antiproliferative effects independent of cyclooxygenase activity and prostaglandin synthesis inhibition. These effects are mediated through inhibition of certain transcription factors such as NF-ka...
متن کاملPerinatal lead exposure affects nitric oxide and cyclooxygenase pathways in aorta of weaned rats.
Perinatal Pb exposure may modulate arterial tone through nitric oxide (NO) and cyclooxygenase products. To investigate this, Wistar dams received 1000 ppm of Pb or sodium acetate (control) in drinking water during pregnancy and lactation. Curves were constructed in phenylephrine-precontracted intact and/or denuded rings of thoracic aortas of weaned (23-day-old) male pups from their responses to...
