Effects of methionine tripeptide on expression of casein and small peptide transporters in bovine mammary epithelial cells
Introduction Milk protein is one of the most important indicators of milk quality.Studies have revealed that small peptides could be absorbed in ruminantanimals, and that in the blood circulation couldbe involved in milk protein synthesis in bovine mammary epithelial cells (BMECs), which made up for the shortage of free amino acidsto some extent during milk protein synthesis in the mammary gland (Tagari et al., 2008).It has been proved that peptide transporter 1 (PepT1) and peptide transporter 2 (PepT2)exist in the mammary gland of dairy cows (Zhou 2011;Cui 2015).They could transport the majority of the dipeptides and tripeptides, but could not transport peptides containing more than 3 amino acid residues (Backwell et al.,1996;Farrell et al., 2004).
