Published: 6 July 2018
... are classified on the basis of their myosin heavy chain (MHC) isoform composition, which are broadly categorised into slow and fast fibres. In humans, these are slow type I and IIa fibres, which are poised towards oxidative metabolism with high fatigue resistance, but low shortening velocity, force and power...

... fibres from four marmoset and nine human VL biopsies, the force–velocity characteristics were determined. Marmoset VL contained almost exclusively fast muscle fibres (>99.0%), of which 63% were type IIB and 37% were hybrid fibres, fibres containing multiple myosin heavy chains. GM contained 9% type I...

..., this period is usually marked by a fast maturation of muscles, during which different myosin heavy chain (MyHC) isoforms are expressed. However, parental food provisioning may fluctuate seasonally, and offspring therefore face a challenge to ensure the necessary maturation of their tissues when energy...

.... The results indicate that masticatory myosin is expressed in some Sciuridae species but not in other closely related species with similar diets but having different nut-opening strategies. We also discovered that the myosin light chain 1 isoform associated with masticatory myosin heavy chain, in the same four...

Plantar flexors in the mini-muscle phenotype exhibit a high capacity for aerobic activity, including altered enzyme activities, loss of expression of type II b myosin heavy chain (MHC), increased expression of type I,II x and II a MHC, and mechanical performance...

... the hypothesis that changes in muscle protein composition underlie the observed changes in contractile performance. We found that gregarine infection was associated with a 10-fold average reduction in abundance of a ∼155 kDa fragment of muscle myosin heavy chain (MHC;∼206 kDa intact size). Insect MHC gene...

To investigate the embryological development of fast and slow muscle in trout embryos, we carried out single and double in situ hybridisation with fast and slow myosin heavy chain (MyHC)-isoform-specific riboprobes. This showed that the slow-MyHC-positive cells originate in a region of the somite close...
