Molecular forms of acetylcholinesterase and pseudocholinesterase in chicken skeletal muscles : their distribution and change with muscular dystrophy

Asymmetric and Globular Forms of AChE in Slow and Fast Muscles of 129/ReJ Normal and Dystrophic Mice

“…These new advances provided a tool for a fuller evaluation of the effect of dystrophy on AChE. Indeed, the molecular forms have already been extensively examined in the dystrophic chicken (Wilson et al, 1979; Barnard et al, 1982;Massoulie and Bon, 1982), but there are fewer studies in dystrophic mice, where the innervation pattern and the molecular forms of AChE more closely resemble those of the human. The work performed on 129/ ReJ dystrophic mice (Sung, 1978a(Sung, , 1980; Skau and Brimijoin, 1981; Stephens, 1981, 1982b) has revealed that in this strain, the dystrophy affects many of the AChE molecular forms, mainly G4 (10s).…”

Research progress on regulating factors of muscle fiber heterogeneity in poultry: a review

“…The expression and distribution of AChE in muscles depend on factors such as muscle fiber type, motor nerve contacts, and contractile activity. In chickens, slowly twitching muscles express G1, G4, and A12 forms of AChE, while fast muscles predominantly express only the A12 form ( Barnard et al, 1982 ). The proline-rich membrane anchor (PRiMA), which organizes AChE into tetrameric spheroids, is anchored similarly to AChE ( Perrier et al, 2002 ).…”
