The Regulatory Role of MeAIB in Protein Metabolism and the mTOR Signaling Pathway in Porcine Enterocytes. [PDF]

, 2018
Amino acid transporters play an important role in cell growth and metabolism. MeAIB, a transporter-selective substrate, often represses the adaptive regulation of sodium-coupled neutral amino acid transporter 2 (SNAT2), which may act as a receptor and ...

Phenylalanine modulates casein synthesis in bovine mammary epithelial cells by influencing amino acid transport and protein synthesis pathways

Frontiers in Nutrition
The efficiency of phenylalanine (Phe) utilization for milk protein synthesis in dairy cows is limited, and its uptake and metabolic mechanisms in the mammary tissue remaining unclear. This study investigated the effects of Phe availability (0.07, 0.14, 0.
