The -300 region of the interleukin 1 beta (IL-1 beta) promoter contains a functional NF-kappa B binding site composed of the decamer sequence 5'-GGGAAAATCC-3'. Probes representing the -300 region or the NF-kappa B site alone interacted with NF-kappa B proteins present in phorbol myristate acetate-, lipopolysaccharide-, or Sendai virus-induced myeloid cell(More)
Multiple regulatory domains within the -100 region of the beta interferon (IFN-beta) promoter control the inducible response of the IFN gene to virus infection. In this study, we demonstrate that the formation of NF-kappa B-specific complexes on the positive regulatory domain II (PRDII) precedes the onset of detectable IFN-beta transcription in Sendai(More)
Molecular, biochemical and epidemiological evidence implicate HTLV-I as an etiologic agent of adult T cell leukemia (ATL). The Tax protein of HTLV-I, a positive transcriptional activator of HTLV-I gene expression, is a viral oncogene that also increases transcription of cellular genes including GM-CSF, IL-2R alpha and IL-2. One of the cellular targets of(More)
In this paper we propose to pave indoor floors with “communicating” tiles in order to extend perception and communication of mobile agents and more generally to implement environment-based multi-agent models. Each tile supports a real-time process which ensures communication with its neighbours and any agent laid on it. We details algorithms required for(More)
Human T-cell leukemia virus type I (HTLV-I) encodes a strong transcriptional activator, Tax, that stimulates transcription indirectly through the viral long terminal repeat and also activates a number of cellular genes via association with host transcription factors. The NF-kappa B/Rel pathway is a target for Tax trans-activation, and Tax has been(More)
The viral oncogene Tax derived from human T cell leukemia virus type I (HTLV-I) is a positive transcriptional activator of HTLV-1 gene expression. Tax is also able to indirectly stimulate transcription of several growth regulatory genes by an indirect mechanism via association with host transcription factors. One of the cellular targets of the(More)
Members of the NF-kappa B/Rel family of transcription factors are involved in the transcriptional regulation of numerous polypeptides important to the immune response and cellular growth. Several genes regulated in part by NF-kappa B/Rel such as interleukin 2, IL-2 receptor alpha, and GM-CSF are trans-activated via an indirect association with the HTLV-I(More)
Gamma spectroscopy is commonly used in nuclear safeguards to measure the enrichment of uranium applying either the enrichment meter method, or analysis codes developed to analyse several γ-rays or Xand γ-rays in defined regions of a uranium spectrum. An experimental design has been carried out for the measurement of uranium enrichment using this technique(More)
