Caseins are essentially concentrated in the colloidal fraction of ruminant milks as highly hydrated and mineralized spherical particles, termed casein micelles. They form a group of four peptide chains (alpha(s1), beta, alpha(s2) and kappa), encoded by four structural genes (CSN1S1, CSN2, CSN1S2 and CSN3, respectively) of which the expression is regulated by lactogenic hormones. These phosphopr...

This study aimed to determine the causes of bitterness problems in white cheese produced by ultrafiltration (UF). To investigate association between with enzyme use or starter culture, was using UF-pasteurized and UF-raw milk two different coagulating enzymes cultures proteolytic activities. Sensory analysis, protein, water-soluble nitrogen, 12% trichloroacetic acid-soluble 5% phosphotungstic n...

BACKGROUND The dual specificity phosphatase cdc25C was the first human cdc25 family member found to be essential in the activation of cdk1/cyclin B1 that takes place at the entry into mitosis. Human cdc25C is phosphorylated on Proline-dependent SP and TP sites when it becomes active at mitosis and the prevalent model is that this phosphorylation/activation of cdc25C would be part of an amplific...

In this study, different adhesives manufactured by using various casein powders (micellar casein, αS-, β- and ĸ-casein fractions, sodium caseinate calcium caseinate) were investigated for their properties potential application in the food industry. Casein-based sources of caseins produced differences adhesive strength determined. For isolation methods selective solubility, precipitation a decan...

Beta casein 1s a major «1 Ik protein produced by the lactating mammary gland and I t s gene expression 1s hormonally controlled ( 1 ) . cDKAs encoding mouse beta casein wore Isolated from a muse maoaary gland l ibrary prepared as described ( 2 ) , using a short cONA clona of mouse beta casein (1) as a hybridization probe. The longest cDNA clone was chossn and the DNA sequence of each strand was...

Protein, generally agreed to be the most satiating macronutrient, may differ in its effects on appetite depending on the protein source and variation in digestion and absorption. We investigated the effects of two milk protein types, casein and whey, on food intake and subjective ratings of hunger and fullness, and on postprandial metabolite and gastrointestinal hormone responses. Two studies w...

Mucous hypersecretion is a serious feature of chronic airway diseases such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis. Although mucins are produced via activation of an EGF receptor (EGFR) signaling cascade, the mechanisms leading to exaggerated mucin production in mucous hypersecretory diseases are unknown. Because expression of ICAM-1 and of the ICAM-1 ligand...
