    Description: The myb-ets-containing acute leukemia virus, E26, transforms myeloblasts and erythroblasts in culture and causes a mixed erythroid and myeloid leukemia in chicks. Genes (ets-1, ets-2, and erg) with variable relatedness to the v-ets oncogene of the E26 virus have been identified, cloned, and characterized in several species. Two new members (elk-1 and elk-2) of the ets oncogene superfamily have now been identified. Nucleotide sequence analysis of the elk-1 cDNA clone revealed that this gene encodes a 428-residue protein whose predicted amino acid sequence showed 82% similarity to the 3' region of v-ets. The elk or related sequences appear to be transcriptionally active in testis and lung. The elk cDNA probe detects two loci in the human genome, elk-1 and elk-2, which map to chromosome regions Xp11.2 and 14q32.3, respectively. These loci are near the translocation breakpoint seen in the t(X;18) (p11.2;q11.2), which is characteristic of synovial sarcoma, and the chromosome 14q32 breakpoints seen in ataxia telangiectasia and other T cell malignancies. This suggests the possibility that rearrangements of elk loci may be involved in pathogenesis of certain tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rao, V N -- Huebner, K -- Isobe, M -- ar-Rushdi, A -- Croce, C M -- Reddy, E S -- CA-21124/CA/NCI NIH HHS/ -- CA-25875/CA/NCI NIH HHS/ -- CA-39860/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):66-70.〈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/2539641" target="_blank"〉PubMed〈/a〉

    Description: Techniques of gene amplification, molecular cloning, and sequence analysis were used to test for the presence of sequences related to human T-lymphotropic virus type I (HTLV-I) in peripheral blood mononuclear cells of six patients with multiple sclerosis (MS) and 20 normal individuals. HTLV-I sequences were detected in all six MS patients and in one individual from the control group by DNA blot analysis and molecular cloning of amplified DNAs. The viral sequence in MS patients were associated with adherent cell populations consisting predominantly of monocytes and macrophages. Molecular cloning and nucleotide sequence analysis indicated that these amplified viral sequences were related to the HTLV-I proviral genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reddy, E P -- Sandberg-Wollheim, M -- Mettus, R V -- Ray, P E -- DeFreitas, E -- Koprowski, H -- CA-10815/CA/NCI NIH HHS/ -- NS-11036/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):529-33.〈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/2536193" target="_blank"〉PubMed〈/a〉

    Description: This Perspective focuses on the future of the Pandemic Influenza Preparedness (PIP) Framework, which was initially established to promote the fair sharing of public health-related pandemic influenza samples between countries. We examine the changes that need to be made to address the growing likelihood that genetic sequence data might be shared instead of physical virus samples, as well as the need to expand the PIP framework's scope and to improve its fairness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gostin, Lawrence O -- Phelan, Alexandra -- Stoto, Michael A -- Kraemer, John D -- Reddy, K Srinath -- New York, N.Y. -- Science. 2014 Sep 12;345(6202):1295-6. doi: 10.1126/science.1257622.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉O'Neill Institute for National and Global Health Law, Georgetown University Law Center, Washington, DC 20001, USA. ; Department of Health Systems Administration, Georgetown University, Washington, DC 20057, USA. ; O'Neill Institute for National and Global Health Law, Georgetown University Law Center, Washington, DC 20001, USA.

    Description: The origin of the Andaman "Negrito" and Nicobar "Mongoloid" populations has been ambiguous. Our analyses of complete mitochondrial DNA sequences from Onges and Great Andaman populations revealed two deeply branching clades that share their most recent common ancestor in founder haplogroup M, with lineages spread among India, Africa, East Asia, New Guinea, and Australia. This distribution suggests that these two clades have likely survived in genetic isolation since the initial settlement of the islands during an out-of-Africa migration by anatomically modern humans. In contrast, Nicobarese sequences illustrate a close genetic relationship with populations from Southeast Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thangaraj, Kumarasamy -- Chaubey, Gyaneshwer -- Kivisild, Toomas -- Reddy, Alla G -- Singh, Vijay Kumar -- Rasalkar, Avinash A -- Singh, Lalji -- New York, N.Y. -- Science. 2005 May 13;308(5724):996.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Cellular and Molecular Biology, Hyderabad-500 007, India.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15890876" target="_blank"〉PubMed〈/a〉

    Description: Endogenous DNA adducts may contribute to the etiology of human genetic disease and cancer. One potential source of endogenous DNA adducts is lipid peroxidation, which generates mutagenic carbonyl compounds such as malondialdehyde. A sensitive mass spectrometric method permitted detection and quantitation of the major malondialdehyde-DNA adduct, a pyrimidopurinone derived from deoxyguanosine. DNA from disease-free human liver was found to contain 5400 adducts per cell, a frequency comparable to that of adducts formed by exogenous carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhary, A K -- Nokubo, M -- Reddy, G R -- Yeola, S N -- Morrow, J D -- Blair, I A -- Marnett, L J -- CA47479/CA/NCI NIH HHS/ -- ES00267/ES/NIEHS NIH HHS/ -- GM42056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Sep 9;265(5178):1580-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉A.

    Description: The cystic fibrosis transmembrane conductance regulator (CFTR) is a chloride ion channel regulated by protein kinase A and adenosine triphosphate (ATP). Loss of CFTR-mediated chloride ion conductance from the apical plasma membrane of epithelial cells is a primary physiological lesion in cystic fibrosis. CFTR has also been suggested to function an an ATP channel, although the size of the ATP anion is much larger than the estimated size of the CFTR pore. ATP was not conducted through CFTR in intact organs, polarized human lung cell lines, stably transfected mammalian cell lines, or planar lipid bilayers reconstituted with CFTR protein. These findings suggest that ATP permeation through the CFTR is unlikely to contribute to the normal function of CFTR or to the pathogenesis of cystic fibrosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reddy, M M -- Quinton, P M -- Haws, C -- Wine, J J -- Grygorczyk, R -- Tabcharani, J A -- Hanrahan, J W -- Gunderson, K L -- Kopito, R R -- DK43994/DK/NIDDK NIH HHS/ -- DK45913/DK/NIDDK NIH HHS/ -- HL42368/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1996 Mar 29;271(5257):1876-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biomedical Sciences, University of California, Riverside, 92521, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8596959" target="_blank"〉PubMed〈/a〉

    Description: In the mammalian ovary, progressive activation of primordial follicles from the dormant pool serves as the source of fertilizable ova. Menopause, or the end of female reproductive life, occurs when the primordial follicle pool is exhausted. However, the molecular mechanisms underlying follicle activation are poorly understood. We provide genetic evidence that in mice lacking PTEN (phosphatase and tensin homolog deleted on chromosome 10) in oocytes, a major negative regulator of phosphatidylinositol 3-kinase (PI3K), the entire primordial follicle pool becomes activated. Subsequently, all primordial follicles become depleted in early adulthood, causing premature ovarian failure (POF). Our results show that the mammalian oocyte serves as the headquarters of programming of follicle activation and that the oocyte PTEN-PI3K pathway governs follicle activation through control of initiation of oocyte growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reddy, Pradeep -- Liu, Lian -- Adhikari, Deepak -- Jagarlamudi, Krishna -- Rajareddy, Singareddy -- Shen, Yan -- Du, Chun -- Tang, Wenli -- Hamalainen, Tuula -- Peng, Stanford L -- Lan, Zi-Jian -- Cooney, Austin J -- Huhtaniemi, Ilpo -- Liu, Kui -- New York, N.Y. -- Science. 2008 Feb 1;319(5863):611-3. doi: 10.1126/science.1152257.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Biochemistry and Biophysics, Umea University, SE-901 87 Umea, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18239123" target="_blank"〉PubMed〈/a〉

    Description: Polyaromatic hydrocarbons (PAHs) are prevalent, potent carcinogens, and 7,12-dimethylbenz[a]anthracene (DMBA) is a model PAH widely used to study tumorigenesis. Mice lacking Langerhans cells (LCs), a signatory epidermal dendritic cell (DC), are protected from cutaneous chemical carcinogenesis, independent of T cell immunity. Investigation of the underlying mechanism revealed that LC-deficient skin was relatively resistant to DMBA-induced DNA damage. LCs efficiently metabolized DMBA to DMBA-trans-3,4-diol, an intermediate proximal to oncogenic Hras mutation, and DMBA-treated LC-deficient skin contained significantly fewer Hras mutations. Moreover, DMBA-trans-3,4-diol application bypassed tumor resistance in LC-deficient mice. Additionally, the genotoxic impact of DMBA on human keratinocytes was significantly increased by prior incubation with human-derived LC. Thus, tissue-associated DC can enhance chemical carcinogenesis via PAH metabolism, highlighting the complex relation between immune cells and carcinogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3753811/" 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/PMC3753811/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Modi, Badri G -- Neustadter, Jason -- Binda, Elisa -- Lewis, Julia -- Filler, Renata B -- Roberts, Scott J -- Kwong, Bernice Y -- Reddy, Swapna -- Overton, John D -- Galan, Anjela -- Tigelaar, Robert -- Cai, Lining -- Fu, Peter -- Shlomchik, Mark -- Kaplan, Daniel H -- Hayday, Adrian -- Girardi, Michael -- 085780/Wellcome Trust/United Kingdom -- K08 AR002072/AR/NIAMS NIH HHS/ -- P30 CA016359/CA/NCI NIH HHS/ -- R01 AR056632/AR/NIAMS NIH HHS/ -- R01 CA102703/CA/NCI NIH HHS/ -- R01-AR044077/AR/NIAMS NIH HHS/ -- R01-AR056632/AR/NIAMS NIH HHS/ -- R01CA102703/CA/NCI NIH HHS/ -- T32 AR007016/AR/NIAMS NIH HHS/ -- Cancer Research UK/United Kingdom -- Department of Health/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):104-8. doi: 10.1126/science.1211600.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, Yale University School of Medicine, New Haven, CT 06520, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223807" target="_blank"〉PubMed〈/a〉
