    Description: An immune response is essential for protection against infection, but, in many individuals, aberrant responses against self tissues cause autoimmune diseases such as rheumatoid arthritis (RA). How to diminish the autoimmune response while not augmenting infectious risk is a challenge. Modern targeted therapies such as anti-TNF or anti-CD20 antibodies ameliorate...

    Description: The Wilms tumor suppressor gene wt1 encodes a zinc finger DNA binding protein, WT1, that functions as a transcriptional repressor. The fetal mitogen insulin-like growth factor II (IGF-II) is overexpressed in Wilms tumors and may have autocrine effects in tumor progression. The major fetal IGF-II promoter was defined in transient transfection assays as a region spanning from nucleotides -295 to +135, relative to the transcription start site. WT1 bound to multiple sites in this region and functioned as a potent repressor of IGF-II transcription in vivo. Maximal repression was dependent on the presence of WT1 binding sites on each side of the transcriptional initiation site. These findings provide a molecular basis for overexpression of IGF-II in Wilms tumors and suggest that WT1 negatively regulates blastemal cell proliferation by limiting the production of a fetal growth factor in the developing vertebrate kidney.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drummond, I A -- Madden, S L -- Rohwer-Nutter, P -- Bell, G I -- Sukhatme, V P -- Rauscher, F J 3rd -- CA 10817/CA/NCI NIH HHS/ -- CA 47983/CA/NCI NIH HHS/ -- CA 52009/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Jul 31;257(5070):674-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1323141" target="_blank"〉PubMed〈/a〉

    Description: The wt1 gene, a putative tumor suppressor gene located at the Wilms tumor (WT) locus on chromosome 11p13, encodes a zinc finger-containing protein that binds to the same DNA sequence as EGR-1, a mitogen-inducible immediate-early gene product that activates transcription. The transcriptional regulatory potential of WT1 has not been demonstrated. In transient transfection assays, the WT1 protein functioned as a repressor of transcription when bound to the EGR-1 site. The repression function was mapped to the glutamine- and proline-rich NH2-terminus of WT1; fusion of this domain to the zinc finger region of EGR-1 converted EGR-1 into a transcriptional repressor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Madden, S L -- Cook, D M -- Morris, J F -- Gashler, A -- Sukhatme, V P -- Rauscher, F J 3rd -- CA-0917-15/CA/NCI NIH HHS/ -- CA-23413/CA/NCI NIH HHS/ -- CA-52009/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Sep 27;253(5027):1550-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute of Anatomy and Biology, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1654597" target="_blank"〉PubMed〈/a〉

    Description: Proper regulation of nuclear factor kappaB (NF-kappaB) transcriptional activity is required for normal lymphocyte function, and deregulated NF-kappaB signaling can facilitate lymphomagenesis. We demonstrate that the API2-MALT1 fusion oncoprotein created by the recurrent t(11;18)(q21;q21) in mucosa-associated lymphoid tissue (MALT) lymphoma induces proteolytic cleavage of NF-kappaB-inducing kinase (NIK) at arginine 325. NIK cleavage requires the concerted actions of both fusion partners and generates a C-terminal NIK fragment that retains kinase activity and is resistant to proteasomal degradation. The resulting deregulated NIK activity is associated with constitutive noncanonical NF-kappaB signaling, enhanced B cell adhesion, and apoptosis resistance. Our study reveals the gain-of-function proteolytic activity of a fusion oncoprotein and highlights the importance of the noncanonical NF-kappaB pathway in B lymphoproliferative disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3124150/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3124150/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosebeck, Shaun -- Madden, Lisa -- Jin, Xiaohong -- Gu, Shufang -- Apel, Ingrid J -- Appert, Alex -- Hamoudi, Rifat A -- Noels, Heidi -- Sagaert, Xavier -- Van Loo, Peter -- Baens, Mathijs -- Du, Ming-Qing -- Lucas, Peter C -- McAllister-Lucas, Linda M -- R01 CA124540/CA/NCI NIH HHS/ -- R01 CA124540-04/CA/NCI NIH HHS/ -- R01 HL082914/HL/NHLBI NIH HHS/ -- R01CA124540/CA/NCI NIH HHS/ -- T32-HD07513/HD/NICHD NIH HHS/ -- T32-HL007622-21A2/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):468-72. doi: 10.1126/science.1198946.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics and Communicable Diseases, University of Michigan, 1150 West Medical Center Drive, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273489" target="_blank"〉PubMed〈/a〉

    Description: Simian acquired immunodeficiency syndrome (SAIDS), a disease clinically and pathologically similar to acquired immunodeficiency syndrome in humans, was transmitted from diseased rhesus monkeys (Macaca mulatta) to normal monkeys by inoculation with heparinized whole blood or plasma that had been passed through filters of 0.45 micrometer pore size. This suggests that the causative agent is small and most probably a virus. No viruses, however, were isolated by standard cell culture techniques from the blood or filtered plasma which caused SAIDS. Both cellular and humoral immunity were markedly depressed in animals with advanced SAIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gravell, M -- London, W T -- Houff, S A -- Madden, D L -- Dalakas, M C -- Sever, J L -- Osborn, K G -- Maul, D H -- Henrickson, R V -- Marx, P A -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Jan 6;223(4631):74-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318315" target="_blank"〉PubMed〈/a〉

    Description: Owl monkeys were inoculated intracerebrally, subcutaneously, and intravenously with JC, BK, or SV40 virus. Two of four adult owl monkeys inoculated with JC virus, a human polyomavirus, developed brain tumors at 16 and 25 months after inoculation, respectively. A grade 3 to grade 4 astrocytoma (resembling a human glioblastoma multiforme) was found in the left cerebral hemisphere and brainstem of one monkey. The second monkey developed a malignant tumor in the left cerebral hemisphere containing both glial and neuronal cell types. Impression smears prepared from unfixed tissue of this tumor showed cells that contained polyomavirus T antigen. Virion antigens were not detected. Tumor cells cultured in vitro also contained T antigen but were negative for virion antigen. Infectious virus was not isolated from extracts of this tumor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉London, W T -- Houff, S A -- Madden, D L -- Fuccillo, D A -- Gravell, M -- Wallen, W C -- Palmer, A E -- Sever, J L -- Padgett, B L -- Walker, D L -- ZuRhein, G M -- Ohashi, T -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1246-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/211583" target="_blank"〉PubMed〈/a〉

    Notes: Isolates of maize stripe tenuivirus (MSt V) from Florida (US), Costa Rica (CR), and Nigeria, Africa (AF), were transmitted to maize plants by the planthopper Peregrinus maidis (from Hawaii) with respective frequencies of 0,18, and 60% after a 1-day acquisition access period on diseased plants, and with frequencies of 18, 71 and 93%, respectively, after a 7-day access period. These isolates were transmitted transovarially to progeny planthoppers with respective frequencies of 21, 32, and 47%. The latent period in the vector, following oral acquisition of MSt V, was significantly longer in the US isolate than in the AF-or CR isolates. ELISA tests of MSt V-inoculative planthoppers indicated a significantly lower titre of MSt V-US compared with MSt V-CR or MSt V-AF. These results suggest that, compared with the US isolate, the AF and CR isolates of MSt V multiply faster and reach higher levels in, and are transmitted more efficiently by, P. maidis from Hawaii.

    Notes: Using a previously developed stochastic simulation model for plant disease epidemics, the relationship of the SADIE aggregation statistic Ia with initial epidemic conditions, spore dispersal distance, sampling quadrat size and other spatial statistics was investigated. Most variation in Ia was attributable to the initial spatial pattern of infected plants and sampling quadrat size. The importance of initial spatial pattern on SADIE clustering indices (for patches and gaps) was also demonstrated using a number of selected data sets. Correlation of Ia with clustering indices was close to 1·0. Epidemics arising from the regular and random initial patterns resulted in the smallest and greatest Ia values, respectively, at sampling times after disease spread had occurred. Furthermore, the variability in Ia between simulation runs also varied greatly with initial patterns, being lowest and greatest for the clumped and random initial patterns, respectively. Ia increased initially and then decreased with increasing incidence, especially for the clumped and random initial patterns. Overall, the effect of median spore dispersal distance on Ia was very small, especially for the random initial pattern. The correlation between Ia and intraclass correlation was generally small and varied greatly between initial patterns. However, there was a high positive correlation between Ia and a parameter describing the rate of decline of autocorrelation over spatial lags, indicating that Ia, clustering indices and autocorrelations measure some common properties of patterns.
