Evaluation 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 کاملCyclo-oxygenase-2 (COX-2) expression at the site of recent myocardial infarction: friend or foe?
BACKGROUND Cyclo-oxygenase-2 (COX-2) is induced in cardiomyocytes only in response to stress, such as ischaemia. OBJECTIVE To assess COX-2 expression at the site of recent myocardial infarction. METHODS COX-2 expression was evaluated by specific immunostaining in cardiomyocytes from 23 subjects who died 10-60 days after acute myocardial infarction. The relation between COX-2 myocardial expr...
متن کاملSelective cyclo-oxygenase-2 inhibitors impair adipocyte differentiation through inhibition of the clonal expansion phase.
Selective cyclo-oxygenase-2 (COX-2) inhibitors are nonsteroidal antiinflammatory drugs used in the management of inflammatory diseases. We demonstrate here that inhibition of the COX-2 enzyme impairs adipocyte differentiation. The inhibition of adipogenesis occurs in the early clonal expansion phase. In particular, COX-2 inhibition limits cell cycle reentry required before terminal adipocyte di...
متن کاملStructure of the human cyclo-oxygenase-2 gene.
Cyclo-oxygenase (Cox), a rate-limiting enzyme in the synthesis of prostanoids, is encoded by two genes, Cox-1 and Cox-2, which are differentially expressed and regulated. Human Cox-1 and -2 polypeptides share 61% primary sequence identity. While the expression of Cox-1 is maximal in quiescent cells. Cox-2 expression is induced by growth factors and cytokines. We have screened a human genomic li...
