Deficiency of COX-1 causes natriuresis and enhanced sensitivity to ACE inhibition [PDF]

open access: yesKidney International, 2001
BACKGROUND: Prostanoid products of the cyclo-oxygenase (COX) pathway of arachidonic acid metabolism modulate blood pressure (BP) and sodium homeostasis. Conventional non-steroidal anti-inflammatory drugs (NSAIDs), which inhibit both COX isoforms (COX-1 and -2), cause sodium retention, exacerbate hypertension, and interfere with the efficacy of certain ...

COX-2 compensation in the uterus of COX-1 deficient mice during the pre-implantation period

Molecular and Cellular Endocrinology, 1999
Prostaglandins (PGs) produced by cyclooxygenase (COX) participate in many aspects of female reproduction. The two isoforms of cyclooxygenase, COX-1 and COX-2, have distinct expression patterns in the mouse uterus during the peri-implantation period and suggest their independent contribution to uterine PGs.

Characterization of the peroxide sensitivity of COX-deficient yeast strains reveals unexpected relationships between COX assembly proteins

Free Radical Biology and Medicine, 2011
A number of distinct cuproproteins of the mitochondrial inner membrane are required for the assembly of cytochrome oxidase (COX), thought to function in a "bucket brigade" fashion to provide copper to the Cu(A) and Cu(B) sites. In yeast, the loss of two these proteins, Sco1p and Cox11p, leads to respiratory deficiency and a specific inability to ...

Identification of a novel deletion in SURF1 gene: Heterogeneity in Leigh syndrome with COX deficiency [PDF]

open access: yesMitochondrion, 2016
Leigh syndrome (LS) is a rare, progressive neurodegenerative mitochondrial disorder of infancy. It is a genetically heterogeneous disease. The mutations in SURF1 gene are the most frequently known cause. Here two cases of LS likely caused by SURF1 gene variants are reported: a 39-year-old male patient with a novel homozygous deletion (c.-11_13del), and

Myoglobinuria and COX deficiency in a patient taking cerivastatin and gemfibrozil

Neurology, 2003
The authors describe a patient who presented with myoglobinuria after starting cerivastatin-gemfibrozil therapy. Muscle histochemistry revealed ragged-red fibers and cytochrome c oxidase negative (COX) fibers, and biochemistry showed a defect of COX activity. Immunoblot analysis showed a 60% reduction of COX I and COX II polypeptides.

Facial Dysmorphism in Leigh Syndrome With SURF-1 Mutation and COX Deficiency

Pediatric Neurology, 2006
Leigh syndrome is an inherited, progressive neurodegenerative disorder of infancy and childhood. Mutations in the nuclear SURF-1 gene are specifically associated with cytochrome C oxidase-deficient Leigh syndrome. This report describes two patients with similar facial features. One of them was a 2(1/2)-year-old male, and the other was a 3-year-old male

Mitochondrial Encephalomyopathy with COX Deficiency

2014
Leigh syndrome, or subacute necrotizing encephalomyopathy, is a progressive neurological disorder characterized by specific neuropathological lesions in the brainstem and basal ganglia. The onset of symptoms occurs typically within 1 year of life (rarely in adolescence).

Deficiency in either COX-1 or COX-2 genes does not affect amyloid beta protein burden in amyloid precursor protein transgenic mice

Biochemical and Biophysical Research Communications, 2016
Epidemiologic studies indicate that chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk for developing Alzheimer's disease (AD). Because the primary mode of action of NSAIDs is to inhibit cyclooxygenase (COX) activity, it has been proposed that perturbed activity of COX-1 or COX-2 contributes to AD pathogenesis.
