Agility is one of the key performance factors important for prevention falls. There a lack tests applicable testing agility in untrained, older and clinical populations. The aim tis research was to investigate reliability validity newly-designed protocol change direction speed (CODS) reactive (RAG) population. Research comprised 25 individuals than 40 years age who underwent knee surgery. Varia...

Precise regulation of Rag (recombination-activating gene) expression is crucial to prevent genomic instability caused by the generation of Rag-mediated DNA breaks. Although mechanisms of Rag activation have been well characterized, the mechanism by which Rag expression is down-regulated in early B cell development has not been fully elucidated. Using a complementary DNA library screen, we ident...

Porphyromonas gingivalis is considered as a major etiological agent in periodontal diseases and implied to result in gingival inflammation under orthodontic appliance. rag locus is a pathogenicity island found in Porphyromonas gingivalis. Four rag locus variants are different in pathogenicity of Porphyromonas gingivalis. Moreover, there are different racial and geographic differences in distrib...

Elucidating the role of carbohydrate quality in human nutrition requires a greater understanding of how the physico-chemical characteristics of foods relate to their physiological properties. It was hypothesised that rapidly available glucose (RAG) and slowly available glucose (SAG), in vitro measures describing the rate of glucose release from foods, are the main determinants of glycaemic inde...

Two lymphoid cell-specific proteins, RAG1 and RAG2 (RAG), initiate V(D)J recombination by assembling a synaptic complex with recombination signal sequences (RSSs) abutting two different antigen receptor gene coding segments, and then introducing a DNA double strand break at the end of each RSS. Despite the biological importance of this system, the structure of the synaptic complex, and the RAG ...

V(D)J recombination is the assembly of gene segments at the antigen receptor loci to generate antigen receptor diversity in T and B lymphocytes. This process is regulated, according to defined developmental programs, by the action of a single specific recombinase complex formed by the recombination antigen gene (RAG-1/2) proteins that are expressed in immature lymphocytes. V(D)J recombination i...

Amino acids stimulate cell growth and suppress autophagy through activation of mTORC1. The activation of mTORC1 by amino acids is mediated by Rag guanosine triphosphatase (GTPase) heterodimers on the lysosome. The molecular mechanism by which amino acids regulate the Rag GTPase heterodimers remains to be elucidated. Here, we identify SH3 domain-binding protein 4 (SH3BP4) as a binding protein an...

Conventional T cells, NK cells and NKT cells have been implicated in the anti-tumor activities induced by IL-12. Here we show that IL-12-induced immune responses are partially impaired in T and NKT cell-deficient RAG-2(-/-) mice, and in NKT cell-deficient CD1(-/-) mice. In response to a small dose (<1000 U) of IL-12, RAG-2(-/-) and CD1(-/-) mice demonstrated reduced cytotoxicity, serum IFN-gamm...

V(D)J recombination requires both lymphoid-specific and generally expressed enzymatic activities. All three known generally expressed activities involved in V(D)J recombination are also involved in DNA double-strand break repair (DSBR). Two of these are components of the DNA-dependent protein kinase (DNA-PK) and include Ku80 and DNA-PK catalytic subunit (DNA-PKcs); the third, XRCC4, is a protei...

The zeta-family dimers (zeta, eta, and gamma) are a group of structurally and functionally related proteins that are expressed in developing thymocytes and function as signal transducing subunits of the T cell antigen receptor (TCR) and certain Ig Fc receptors. Zeta, eta, and gamma each contain one or more copies of a conserved tyrosine-based activation motif (TAM) that is known to be required ...
