Fresh cheese was prepared from caprine milk by isoelectric precipitation as a model experiment for reducing the allergenicity of milk. After acidic precipitation of casein, the beta-lactoglobulin content in curd was determined by ELISA using monoclonal antibody (MAb-beta209). The beta-lactoglobulin content was very high in the fresh cheese obtained from heat-treated (85 degrees C) bovine or cap...

A protein kinase, able to phosphorylate casein, phosvitin, and glycogen synthase, was purified approximately 9000-fold from rabbit liver, and appeared analogous to an enzyme studied by Itarte and Huang (Itarte, E., and Huang, K.-P. (1979) J. Biol. Chem. 254, 4052-4057). This enzyme, designated here casein kinase-1, was shown to be a distinct glycogen synthase kinase and in particular to be diff...

This work evaluated the angiotensin-converting-enzyme (ACE)-inhibitory activities of a bovine sodium caseinate fermentate generated using the proteolytic capabilities of the porcine small intestinal isolate Lactobacillus animalis DPC6134 (NCIMB deposit 41355). The crude 10-kDa L. animalis DPC6134 fermentate exhibited ACE-inhibitory activity of 85.51% (+/-15%) and had a 50% inhibitory concentrat...

Allergen-specific immunotherapy (AIT) has been recently considered as an alternative approach to ameliorate the symptoms of allergen exposure and improvement the patients' quality of life. Dendritic cells (DC) in the forms of tolerogenic or Th1-induced cells have been investigated in several studies as one of the promising approaches of AIT in allergic diseases. The aim of this study was to eva...

More than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. Kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. The present study describes polymorphism of kappa casein gene. This is the first study of kappa casein gene polymorphism in Najdi cattle of Iran. We used the polymerase chain r...

We have utilized primary cultures of rat mammary epithelial cells to study mechanisms by which laminin regulates the prolactin-dependent accumulation of alpha-casein mRNA. Mammary cells accumulate approximately fivefold more alpha-casein mRNA when cultured on laminin than when cultured on tissue plastic and the accumulation of alpha-casein mRNA is prolactin dependent. On the basis of transcript...
