Abstract

Summary: Myostatin, also known as growth differentiation factor 8, a member of the transforming growth factor‐beta super‐family, is a negative regulator of muscle development. Myostatin acts at key points during pre‐ and post‐natal life of amniotes that ultimately determine the overall muscle mass of an animal. Mutations have already demonstrated the impact of attenuating myostatin activity on muscle development. A number of large animals, including cattle, sheep, dogs and humans, display the ‘double muscled’ phenotype due to mutations in the myostatin gene. Here, we firstly give an overview of the molecular pathways regulated by myostatin that control muscle development. Then we describe the natural mutations and their associated phenotypes as well as the physiological influence of altering myostatin expression in livestock animals (cattle, sheep, goat, horse, pig, rabbit and chicken). Knowledge of null alleles and polymorphisms in the myostatin gene are of great interest in the animal breeding field, and it could be utilized to improve meat production in livestock animals.

  • Minimizing muscle mass during caloric restriction can substantially reduce energy expenditure, thus sparing energy for the maintenance of other more critical organ systems.

    The Myostatin section describes how myostatin limits muscle development, but does not discuss caloric restriction or energy expenditure. A search for those terms and for energy being spared for other organs found no supporting passage in our copy; the Double muscling phenotypes section discusses exercise-related metabolism instead.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
