Short communication: Arginase inhibition reduces the synthesis of casein in bovine mammary epithelial cells

The main purpose of this work was to determine the effect of arginase inhibition via Nω-hydroxy-nor-l-arginine (nor-NOHA) on casein synthesis in bovine mammary epithelial cells (BMEC). Passage 2 BMEC isolated from dairy cows were seeded to 6-well plates and randomly divided into 4 treatments: (1) control [Dulbecco's modified Eagle medium:Nutrient Mixture F-12 medium (DMEM/F12)]; (2) nor-NOHA (DMEM/F12 + 1 mmol/L nor-NOHA); (3) nor-NOHA +...
