Genetic Variation of An Esterase System in Sera of Dogs
Genetisk variasjon av et esterase system i sera fra hund.
Acta Veterinaria Scandinavica volume 25, pages 526–535 (1984)
Abstract
Sera from 7 dog families comprising 20 parents with 48 offspring and 70 unrelated dogs of various breeds have been studied with regard to polymorphism of esterases. Isoelectric focusing in Polyacrylamide gels of pH ranges 4.2–4.9 and 4–6 revealed great variation of phenotypes. These appeared as complex band patterns always with more than 8 zones. Treatment with an organophosphorous compound and ions of heavy metals strongly indicate that the majority of zones represent arylesterase (ArE) whereas some of the bands are Cholinesterase. ArE phenotypes in families together with the appearances of band patterns in the 70 unrelated dogs are in agreement with a genetic theory of 1 locus with 5 codominant alleles. These have temporarily been named ArED, ArEH, ArEK, ArEQ and ArEW with ArED being the most anodal phenotype and the others in logical order. The ArEK and ArEQ were most common but phenotypes representing the ArED, ArEH and ArEW alleles were each observed in several animals.
Sammendrag
Esterase polymorfisme er blitt undersøkt i serum prøver fra 7 hundefamilier, 20 foreldre med 48 avkom, og i 70 prøver fra ubeslektede hunder av forskjellige raser. Isoelektrisk fokusering i polyacrylamidgeler i pH omradene 4.2–4.9 og 4–6 og med spesifikk farging resulterte i et stort antall forskjellige fenotyper. Disse viste seg som komplekse båndmønstre, alltid med flere enn 8 bånd. Behandling med en organisk fosforforbindelse og med joner av tunge metaller tyder på at flesteparten av disse bånd er arylesterase (ArE) mens noen av dem er Cholinesterase. ArE fenotypene i det undersøkte materiale tyder på en genetisk teori med et locus og fem kodominante alleler. Disse har fått den foreløpige betegnelse ArED, ArEH, ArEK, ArEQ og ArEW hvor ArED fenotypen har sin plass naermest anoden og med de andre i logisk orden. ArEK og ArEQ allelene var vanligst, men fenotyper av ArED, ArEH og ArEW ble alle observert i flere dyr.
