Cobb 700 broiler breeders were randomly assigned to one of six diets in a 2×3 factorial fashion. Two levels of energy (390 and 450 kcal/day) and three levels of protein (22, 24, and 26 g CP/day) were utilized. Protein turnover was determined in the left pectoralis at 22, 26, 31 and 44 weeks. Relative mRNA expression of calpain 2 ([[CAPN2]]), proteasome [[C2]] subunit ([[PSMA1]]), and F box protein 32 ([[FBXO32]]) were determined via RT-PCR at 20, 25, and 44 weeks. Contrasts indicate fractional synthesis rate (FSR) and [[FBXO32]] increase to a maximum at 25-26 weeks and a decrease thereafter. A significant drop in [[PSMA1]] and [[FBXO32]] was observed between 25 and 44 weeks and matched the decrease observed in FBR. No differences were detected in the levels of fractional synthesis and degradation, or the expression of [[CAPN2]], [[PSMA1]], and [[FBXO32]], due to protein or energy intake. In summary, protein turnover was upregulated during the transition into sexual maturity and decreased thereafter. The observed changes in degradation appeared to be mediated by the ubiquitin-proteasome pathway.<br /> |mesh-terms=* Aging<br /> * Animal Feed<br /> * Animals<br /> * Chickens<br /> * Dietary Proteins<br /> * Energy Intake<br /> * Female<br /> * Gene Expression Regulation<br /> * Mammary Glands, Animal<br /> * Muscles<br /> * Oviposition<br /> * Proteolysis<br /> * RNA, Messenger<br /> <br /> |full-text-url=https://sci-hub.do/10.1016/j.cbpb.2012.10.002<br /> }}</div>
