“…For the effect of age on tissue protein synthesis, many investigators reported that protein synthesis declined in specific tissues (e. g., liver or muscle) and the whole body throughout development in mammals after weaning (11)(12)(13)(14). We demonstrated that the rate of protein synthesis in the brain decreased with age in rats after weaning (15).…”

“…The most commonly studied tissues include skeletal muscle, liver and gastrointestinal tissues. Protein synthesis is affected by a variety of physiological conditions imposed by lactation (Vincent & Lindsay, 1985), cold temperatures (Thompson et al 1987), endocrine manipulation (Vernon, 1989), age (Attaix et al 1986). diet composition and level of intake (Garlick et al 1985;Boisclair et al 1987;Jepson et al 1988) and sepsis (Hasselgren et al 1986) (Tables 2 and 3).…”

Whole-body heat production is a consequence of several biochemical events. Specific sites of heat production have been isolated, some being greater contributors to whole-body oxygen consumption than others. Tissues of the splanchnic bed (the gastrointestinal tract and liver) make up only 4 4 % of whole-body mass, but account for 40% of total ATP utilization. Skeletal muscle accounts for a much larger proportion of whole-body mass (50%), but accounts for only 20% of whole-body ATP use. Two major biochemical events contributing to energy use are Na+,K+-ATPase (EC 3.6.1.3) activity and protein turnover. Discussion of these two processes will dominate the present paper but reference will be made to other energy-consuming processes within selected tissues.First, a major contributor to cellular energetics is the activity of the enzyme Na+,K+-ATPase, which extrudes three Na+ from the cell and moves two K' into the cell against their respective concentration gradients at the cost of one high-energy phosphate bond (Balaban et al. 1980). The actions of this enzyme are responsible for the active transport of substrates, maintenance of ionic homeostasis, membrane potential and cell multiplication (Rosier et al.

The purpose of this study was to determine whether the quantity and quality of dietary protein affected the rate of brain protein synthesis in ovariectomized female rats. Two experiments were conducted on the ovariectomized female rats (12 weeks old) given diets containing 20%, 5%, or 0% casein (experiment 1) and 20% casein, 20% soy protein, 20% gluten, or 20% gelatin (experiment 2) for 10 d, respectively. The fractional rates of protein synthesis in the brain declined with a decrease of the quantity and quality of dietary protein. In the brain, the RNA activity [g of protein synthesized/((g of RNA) d)] was significantly correlated with the fractional rate of protein synthesis. The RNA concentration (mg of RNA/g of protein) was not related to the fractional rate of protein synthesis in any organ. The results suggest that the rate of protein synthesis in the brain declines with the decrease of the quantity and quality of dietary protein in ovariectomized female rats, and that RNA activity is at least partly related to the fractional rate of brain protein synthesis.
