Previous research with an animal model of retinoid-induced hypertriglyceridemia, rats fed a 13-cis retinoic acid-containing diet in which casein was the dietary protein, has demonstrated that replacement of dietary casein with soy protein isolate can reduce the severity of this condition. A depressant action of soy protein vs. that of casein on serum triglyceride concentration has also been dem...

Liquid micellar casein concentrate (MCC) is an ideal milk-based protein ingredient for neutral-pH ready-to-drink beverages. The texture and mouthfeel of liquid MCC-based beverages depend on the beverage content as well composition soluble proteins in aqueous phase around micelle. objective this study was to determine micelles skim milk MCC containing 7.0 11.6% content. Skim pasteurized concentr...

1. The influence of temperature, moisture content and the presence of glucose on the level of available methionine and cysteine in casein was studied. 2. Differences between total and available methionine and cysteine contents of heated casein (90 degrees for 24 h) were determined by an in vitro method. The maximum losses in total and available methionine content were 22 and 51% respectively. T...

The use of 4,4-difluoro-5,7-dimethyl-4-bora-3a, 4a-diaza-s-indacene-3-propionic acid (BODIPY-FL) labeled casein in autoquenching assays of proteolytic activity has been recently described, and we have adapted this assay to measurement of calpain activity. BODIPY-FL coupled to casein at a ratio of 8 mol of BODIPY-FL/mol of casein or higher produces a BODIPY-FL-casein substrate that can be used i...

κ-casein is a glycosilated protein in mammalian milk that plays an essential role in the milk micelles. Control of κ-casein expression reflects this essential role, although an understanding of the mechanisms involved lags behind that of the other milk protein genes. Transcriptional regulation, a first mechanism for controlling the development of organisms, is carried out by transcription facto...

Dietary proteins are recognized by the gastrointestinal tract to display physiological functions, however, the sensory mechanism of the intestinal mucosa is not known. We examined binding properties between the rat small intestinal brush-border membrane (BBM) and proteins by using a surface plasmon resonance biosensor. BBM and solubilized BBM prepared from the rat jejunum bound to casein immobi...

milk is an important component of a balanced diet and contains many valuable constituents. a considerable part of the milk healthbenefits is related to its proteins, not only for their nutritive value but also for their biological properties. scientific evidence suggests that anticarcinogenic activities, antihypertensive properties, immune system modulation, and other metabolic features of milk...

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...

The mammary gland is a system in which the components of the blood stream which are used by body tissues for protein synthesis can be readily investigated (Barry, 1956). Previous work has shown that the mammary gland takes the free essential amino acids from the blood stream to provide the essential amino acids of casein (Barry, 1952; Campbell & Work, 1952; Askonas, Campbell, Godin & Work, 1955...

PURPOSE Despite most epidemiologic studies reporting that an increase in milk intake affects the growth of prostate cancer, the results of experimental studies are not consistent. In this study, we investigated the proliferation of prostate cancer cells treated with casein, the main protein in milk. MATERIALS AND METHODS Prostate cancer cells (LNCaP and PC3), lung cancer cells (A459), stomach...
