The authors analyzed butyrylcholinesterase status in melanocytic pathology and possible association of enzyme activity with melanoma diagnose and progression. Butyrylcholinesterase activity showed no changes between melanoma and dysplastic nevi, between melanoma and control, between nevi and control, but it had a statistically significant variation between primary and metastatic melanoma. Butyr...

BACKGROUND Low serum butyrylcholinesterase activity was associated with all-cause and cardiovascular mortality in a community-based study; however, there are no data from investigations of the long-term effects of butyrylcholinesterase on mortality in patients with diagnosed coronary artery disease (CAD). We therefore assessed the effect of butyrylcholinesterase activity on the outcomes of pati...

PURPOSE Acetylcholinesterase and butyrylcholinesterase are two closely related enzymes important in the metabolism of acetylcholine and anaesthetic drugs, including succinylcholine, mivacurium, and cocaine. The solanaceous glycoalkaloids (SGAs) are naturally occurring steroids in potatoes and related plants that inhibit both acetylcholinesterase and butyrylcholinesterase. There are many clinica...

DNA of 3 unrelated individuals carrying the human plasma butyrylcholinesterase C5 variant (CHE2) was isolated from white blood cells. Southern blot patterns of DNA restriction fragments probed with each of the 4 butyrylcholinesterase exons provided evidence that the production of C5 is not directed by a second butyrylcholinesterase gene. This finding supports the suggestion that the C5 variant ...

Butyrylcholinesterase is an enzyme with few known physiological functions. It is related to acetylcholine that was shown to be expressed in a variety of life forms. We performed a search using the human butyrylcholinesterase gene (HGNC:983;MIM:177400), and found the sequence in a broad spectrum including plants, bacteria and animals. Therefore butyrylcholinesterase appears to have evolved early...

OBJECTIVE To investigate the effect of obstructive sleep apnea and continuous positive airway pressure treatment on serum butyrylcholinesterase activity and ischemia-modified albumin levels. METHODS Thirty-two patients with obstructive sleep apnea and 30 age- and sex-matched controls were enrolled and underwent a diagnostic polysomnogram. The serum butyrylcholinesterase activity, ischemia-mod...

The question addressed is whether an increased intake of cholesterol affects esterase-1 (EC 3.1.1.1; ES-1) and butyrylcholinesterase (EC 3.1.1.8) activity in plasma. Rats were fed on a purified diet either without or with cholesterol (10 g/kg) added at the expense of the carbohydrate source. Dietary cholesterol significantly decreased plasma butyrylcholinesterase activity, but raised plasma ES-...

BACKGROUND Succinylcholine remains the standard neuromuscular blocking drug for tracheal intubation in emergency situations. The short duration of action is due to its rapid hydrolytic degradation by butyrylcholinesterase (plasmacholinesterase). Multiple variants of this enzyme are known (A, F, S, H, J, K variants) with different effects on enzyme activity. This study was undertaken to evaluate...

Butyrylcholinesterase is involved three different enzymatic activities in its structure like its sister enzyme, acetylcholinesterase: esterase, aryl acylamidase and peptidase (or protease). Whereas the clear role of acetylcholinesterase in cholinergic neurotransmission is well defined, the real physiological function of butyrylcholinesterase is still unknown. Both enzymes have similar molecular...

Recognition of butyrylcholinesterase (EC 3.1.1.8) variants in human serum is essential to identify patients who may be susceptible to a prolonged reaction of suxamethonium and mivacurium, short-acting muscle relaxants. Thus they can be given appropriate advice along with their relatives who may be similarly affected. Therefore, Cholinesterase Unit for detection of individuals, carriers of inher...
