Essential Amino Acid (EAA) Regulation of Skeletal Muscle Protein Turnover with Age
<p>Skeletal muscle (SM) is vital for both long term health and quality of life. Recent research suggests an increase in catabolic signals with age triggers pathologic conditions, such as sarcopenia. Although results from in vitro studies model how EAA can regulate muscle protein synthesis (MPS), …

The Essential Role of the Non-Essential Amino Acid Asparagine in Lymphoid Malignancies
… It has been extensively shown in cancers, that amino acids have functions beyond the role of mRNA translation. The breadth of functions makes amino acid restriction an effective strategy for cancer therapy; hence an important line of research involves targeting amino acid acquisition and …

Essential Amino Acid Regulation of Cell Signaling and Casein Synthesis in Mammary Tissue
… in lysis buffer and caseins were precipitated by acidification to pH<br />4.6. An aliquot of the pellet was trypsinized and 2H5 Phe enrichment in the 34-<br />NLLRFFVAPFPE-45 peptide of "-S1 casein was measured by MALDI TOF-MS and<br />used to determine CFSR (%/h). Western immunoblotting was …

Responses of Two Strains of Broilers to Diets Varying in Essential Amino Acid Density and Energy Levels
… strains of broilers to diets varying in overall amino acid levels and metabolizable energy levels were observed. Amino acid levels used were 80%, 90%, 100%, 110%, 120%, and 130% of Ross recommended minimum digestable levels of essential amino acids. Energy levels used were either below or above …

The nutritive value of soy flour and soy protein isolate for human adults
… isolate in human adults. By equalizing the essential amino acid patterns of the flour and the isolate, it was considered possible to measure any difference in nutritive value of the two protein sources. The subjects were 18 healthy women ranging in age from 20 to 25 years. A basal diet …

Non-Canonical Roles of Cytosolic Phosphoenolpyruvate Carboxykinase in Small Intestine Metabolism
… (PEPCK) is considered by many to be the quintessential regulatory enzyme of gluconeogenesis. This common perspective of PEPCK solely functioning in gluconeogenesis is too narrow and does not do justice to the complexity and number of pathways in which this enzyme participates. PEPCK performs …

Diet, inflammation and skeletal muscle mass in women
… short-term dietary interventions with essential amino acid supplementation have shown promising effects on muscle protein synthesis. Emerging evidence suggests that a number of nutrients may be associated with muscle mass and strength either due to their anti-inflammatory properties or …

Chickpeas as a protein and energy supplement for high producing dairy cows
… (C<sub>12</sub>-C<sub>16</sub> ) chain fatty acids ( 53.8, 48.6, 45.5 g/l00 g fat) and long chain (C18 ) fatty acids (29.4, 35.0, 38.8 g/l00 g fat) and milk protein (3.20, 3.09, 2.96 %) differed for all three diets. Ruminal acetate: propionate ratio {2.03, 1.98, 2.39) was highest for cows fed …

Serine Metabolism Leverages the Integrated Stress Response to Direct Stem Cell Fate During Tissue Regeneration
… poorly understood. Here, I uncover the non-essential amino acid serine as a surprising regulator in this process. Utilizing dietary intervention and HFSC-specific loss-of-function studies, I demonstrate that under serine-depleted conditions HFSCs delay hair growth. Upon injury, …

The isolation, modification and evaluation of field pea proteins and their applications in foods
… important in balancing the deficiencies of this essential amino acid in cereal-based diets. In recent years, interest in plant proteins for feed and food led to the evaluation of field peas as an economical and nutritional source of proteins. Although some research work has been done on the …

The role of protein and starch of legumes and cereals on the formation of healthy snack products
… minerals. They are also an excellent source of essential amino acid lysine. Unfortunately, legume seeds that grow in New Zealand are considered as a low value crop and mainly used in animal feed production. However, we believe that combinations of legumes and cereals grown in New Zealand could …

Comparative enzymology of wheat germ aspartate transcarbamoylase and related studies
… from various organisms have been reviewed. The amino acid composition, isoelectric point and peptide maps of purified wheat germ aspartate transcarbamoylase have been elucidated and compared to the E.coli enzyme. Three types of essential amino acid residues have been demonstrated by chemical …

Effects of inulin or yeast cell wall extract on nutrient digestibility and fecal fermentative end-product concentrations of healthy adult dogs fed raw diets
… concentrations, but fecal short-chain fatty acid concentrations were increased (P<0.05) with inulin and YCW inclusion in dogs fed beef-based diets. Fecal spermine concentrations were increased (P<0.05) with inulin and YCW inclusion. In general, blood cell populations and metabolites were …

Structural and Functional Insights into Ghrelin Acylation by Ghrelin O-Acyltransferase
… the GHSR1a G-protein-coupled receptor. This 28 amino acid peptide stimulates appetite and has been associated with the cardiovascular, gastrointestinal, neuroendocrine, and immune systems. Ghrelin requires a unique posttranslational modification to be biological active. Ghrelin O-acyltransferase …

The Effects of Aging on Muscle Loss and Nuclear Factor Kappa-B Levels in Rats Fed a Diet Containing Suboptimal Leucine Levels
… in age-related muscle loss. Leucine is an essential amino acid that is required for both protein synthesis and intracellular signaling pathways that regulate protein synthesis and degradation. The current study examined muscle NF-kB levels in male Sprague-Dawley rats, aged 6 (adult) and 21 …
