We have detected hormone response elements in the promoter region of the rat beta-casein gene that confer the synergistic action of prolactin and glucocorticoid hormones upon transcription of chimeric gene constructs. A 2800-base-pair (bp) rat beta-casein gene fragment containing 2300 bp of 5' flanking sequence was placed in front of a chloramphenicol acetyltransferase (CAT) reporter gene and s...
Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...
The mammalian-specific casein gene cluster comprises 3 or 4 evolutionarily related genes and 1 physically linked gene with a functional association. To gain a better understanding of the mechanisms regulating the entire casein cluster at the genomic level we initiated a multispecies comparative sequence analysis. Despite the high level of divergence at the coding level, these studies have ident...
The importance of milk proteins and the positive effect of administration of growth hormone (GH) on milk production, and the presence in some dairy cattle lines of greater GH concentrations prompted us to examine the presence of restriction fragment length polymorphism at the GH gene using the restriction enzyme TaqI and to investigate associations between this polymorphism in Simmental cows an...
Monoclonal antibodies (mAb) to streptococcal group A carbohydrate (GAC) are encoded by a minimum of two VH, four JH, four V kappa, three J kappa, one V lambda, and one J lambda gene segments. The IdX, IdI-1, and Id5 idiotypic determinants are expressed by anti-GAC mAb and are found on free kappa chains. Each pattern of these determinants is encoded by a distinct V kappa gene segment, apparently...
Idiotype variants of 38C13, a murine B cell lymphoma, have been isolated by immunoselection with antiidiotype mAbs. The V region genes for the kappa light chains and mu heavy chains expressed by these tumor cells were sequenced and compared. There was no evidence for V region somatic point mutation in this tumor. However, while the heavy chain genes were all identical, the light chain genes wer...
