Psoas muscle of rats starved for 2 or 4 days contained increased levels of ribosomal subunits and exhibited reduced rates of protein synthesis in vitro, demonstrating a starvation-induced inhibition of peptide-chain initiation. The activity of an eIF-2-like initiation factor, assayed in postribosomal supernatants, decreased in psoas during starvation, parallel to a 25% reduction in the RNA level. Reduced eIF-2 activity did not result from nucleotide depletion or increased deacylation of initiator tRNA, nor was it abolished by extensive dialysis. Perfusion of psoas muscle in the presence of insulin reversed the starvation-induced block in peptide-chain initiation, but did not alter the activity of eIF-2 or level of RNA. Furthermore, heart muscle did not manifest a starvation-induced block in peptide-chain initiation even though the activity of eIF-2 and the level of RNA decreased as a result of food deprivation. Thus loss of eIF 2 activity in psoas and heart did not parallel changes in peptide-chain initiation but was associated with a reduction in tissue RNA. These results indicate that the level of eIF-2 is not rate-limiting for peptide-chain initiation under the conditions tested in this study.

Farm-animal species play crucial roles in satisfying demands for meat on a global scale, and they are genetically being developed to enhance the efficiency of meat production. In particular, one of the important breeders’ aims is to increase skeletal muscle growth in farm animals. The enhancement of muscle development and growth is crucial to meet consumers’ demands regarding meat quality. Fetal skeletal muscle development involves myogenesis (with myoblast proliferation, differentiation, and fusion), fibrogenesis, and adipogenesis. Typically, myogenesis is regulated by a convoluted network of intrinsic and extrinsic factors monitored by myogenic regulatory factor genes in two or three phases, as well as genes that code for kinases. Marker-assisted selection relies on candidate genes related positively or negatively to muscle development and can be a strong supplement to classical selection strategies in farm animals. This comprehensive review covers important (candidate) genes that regulate muscle development and growth in farm animals (cattle, sheep, chicken, and pig). The identification of these genes is an important step toward the goal of increasing meat yields and improves meat quality.
