Cyclooxygenase-1 and Cyclooxygenase-2 in the Human Optic Nerve Head

Experimental Eye Research, 1997
To investigate the hypothesis that eicosanoids act as cellular mediators in the optic nerve head of normals and of patients with glaucoma, we have determined the presence of the two cyclooxygenase (COX) isoforms in human tissue. Histological sections of optic nerve heads were studied by immunohistochemistry. Age matched normal donors were compared with

Perspectives on the Cyclooxygenase-2/ Cyclooxygenase-1 Hypothesis

JCR: Journal of Clinical Rheumatology, 1998
The introduction of the cyclooxygenase (COX) hypothesis to explain both the therapeutic effects and the toxicity of nonsteroidal anti-inflammatory drugs (NSAIDs) has provided direction for the development of preferential and highly selective COX-2 inhibitors, which retain efficacy against inflammation with reduced risk of toxicity. However, the complex

The febrile response to lipopolysaccharide is blocked in cyclooxygenase-2−/−, but not in cyclooxygenase-1−/− mice

Brain Research, 1999
Various lines of evidence have implicated inducible cyclooxygenase-2 (COX-2) in fever production. Thus, its expression is selectively enhanced in brain after peripheral exogenous (e.g., lipopolysaccharide [LPS]) or endogenous (e.g., interleukin-1) pyrogen administration, while selective COX-2 inhibitors suppress the fever induced by these pyrogens.

Characteristics of cyclooxygenase-1 and cyclooxygenase-2-deficient mice

1996
The prostaglandins (PGs) are a diverse group of autocrine and paracrine hormones that mediate many cellular and physiological processes. Prostaglandin H2 (PGH2) is an obligate intermediate in formation of prostaglandins1, the formation of which from arachidonic acid (AA) is catalysed by prostaglandin H synthase, an enzyme with two known isoforms ...

Ontogeny of cyclooxygenase-1 and cyclooxygenase-2 gene expression in ovine lung

American Journal of Physiology-Lung Cellular and Molecular Physiology, 1998
Prostacyclin is a key mediator of pulmonary vascular and parenchymal function during late fetal and early postnatal life, and its synthesis in whole lung increases during that period. The rate-limiting enzyme in prostacyclin synthesis in the developing lung is cyclooxygenase (COX).

Immunocytochemical localization of cyclooxygenase-1 and cyclooxygenase-2 in the rat stomach

The Histochemical Journal, 1995
Prostaglandins are considered to play important roles in gastric mucosal protection. The rate-limiting enzyme involved in the biosynthesis of prostaglandins is cyclooxygenase (COX), also known as prostaglandin H synthase. Two forms of COX are known: a constitutively expressed form (COX-1) and a newly-characterized, inducible form (COX-2).

Evaluation of cyclooxygenase‐1 and cyclooxygenase‐2 expression and the effect of cyclooxygenase inhibitors in canine prostatic carcinoma

Veterinary and Comparative Oncology, 2004
AbstractProstatic carcinoma occurs primarily in older castrated male dogs and is typically a fatal disease (most dogs die within few months after the initial diagnosis). Surgery, i.e., total prostatectomy, or radiation therapy is often not pursued due to risks of complications and a high rate of distant metastasis.

Profiling the interaction of 1‐phenylbenzimidazoles to cyclooxygenases

Journal of Molecular Recognition, 2019
AbstractIn the design of 1‐phenylbenzimidazoles as model cyclooxygenase (COX) inhibitors, docking to a series of crystallographic COX structures was performed to evaluate their potential for high‐affinity binding and to reproduce the interaction profile of well‐known COX inhibitors. The effect of ligand‐specific induced fit on the calculations was also

Different Methods for Testing Potential Cyclooxygenase-1 and Cyclooxygenase-2 Inhibitors

2010
The need for the development of selective agents, which only inhibit the mainly "harmful" cyclooxygenase-2 (COX-2) while leaving physiological COX-1 mostly unaffected, still remains, especially after the recent issues related to cardiovascular toxicity caused by some COX-2 selective agents.

Differential expression of cyclooxygenase-1 and cyclooxygenase-2 in the cornea during wound healing

Tissue and Cell, 2004
Cyclooxygenases (COXs) are the key enzymes in the production of prostaglandins (PGs) and exist in two isoforms. Isoform 1 (COX-1) is constitutively expressed in most tissues, whereas cyclooxygenase-2 (COX-2) is rapidly induced by a variety of different stimuli.
