The main goal of the current work was to identify single nucleotide polymorphisms (SNP) that might create or disrupt microRNA (miRNA) target sites in the caprine casein genes. The 3' untranslated regions of the goat alpha(S1)-, alpha(S2)-, beta-, and kappa-casein genes (CSN1S1, CSN1S2, CSN2, and CSN3, respectively) were resequenced in 25 individuals of the Murciano-Granadina, Cashmere, Canarian...
The objective of this study was to compare 12 bp-duplication polymorphisms in exon 4 of the κ-casein gene among 3 breeds/populations of yak (Bos grunniens). Genomic DNA was extracted from yak blood or muscle samples (N = 211) and a partial sequence of exon 4 of κ-casein gene was amplified by polymerase chain reaction. A polyacrylamide gel electrophoresis assay of the products (169 bp) revealed ...
We have analyzed the structure of Ig kappa chain genes in B cell lines derived from a human individual who cannot synthesize any kappa chains, and whose Igs all contain lambda chains (1). We have characterized secondary DNA recombination events at two kappa alleles which have undergone misaligned V-J recombinations. One such secondary recombination has joined the flanking sequences of a V kappa...

We report here that human monocytic/macrophage THP-1 cells express the neurokinin 1 receptor (NK-1R), and that exposure of these cells to the proinflammatory cytokine IL-1 beta increased the expression of the NK-1R gene at the mRNA and protein levels. Because IL-1 beta function involves nuclear factor kappa B (NF-kappa B) activation, these data suggest that this increase in the expression of th...
Protein is one of the nutrient components in milk that related to product quality. The protein are divided into casein alpha-s1, beta, alpha-s2, kappa, and whey fractions such as alpha lactalbumin beta lactoglobulin. There no existing data fraction dairy cow goats Banyumas Regency. This study aimed determine profile form goat Banyumas. Milk sample from fifty cows thirty was taken by random samp...
We tested the hypothesis that extensive undiscovered genetic diversity exists in important functional genes from domestic and wild cattle species (Bos spp.). We resequenced 483 bp of a key exon (exon IV) from the kappa (kappa)-casein gene (CSN3) for a panel of samples of domestic cattle from 8 countries and a close relative species, the gayal (Bos frontalis). Six single nucleotide polymorphisms...
V kappa gene family expression among LPS-reactive murine B lymphocytes, unlike that of VH gene families, is not proportional to genomic complexity, i.e., nonstoichiometric. Furthermore, no positional bias for the overexpression of J-proximal V kappa genes (V kappa 21) is observed among neonatal B lymphocytes. Yet, the V kappa 1 and V kappa 9 families located in the center of V kappa locus are p...
Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...
Transcription of the milk protein beta-casein gene is induced by the lactogenic hormones Prl (prolactin) and glucocorticoids. Multiple transcription factors involved in this induction have been identified, including the STAT5 (signal transducer and activator of transcription 5) and the GR (glucocorticoid receptor). Our previous studies have identified a binding site for the ubiquitous Oct-1 (oc...
