    Description: The gp120 envelope glycoprotein of the human immunodeficiency virus (HIV), which is expressed on the surface of many HIV-infected cells, binds to the cell surface molecule CD4. Soluble derivatives of recombinant CD4 (rCD4) that bind gp120 with high affinity are attractive vehicles for targeting a cytotoxic reagent to HIV-infected cells. Soluble rCD4 was conjugated to the active subunit of the toxin ricin. This conjugate killed HIV-infected H9 cells but was 1/1000 as toxic to uninfected H9 cells (which do not express gp120) and was not toxic to Daudi cells (which express major histocompatibility class II antigens, the putative natural ligand for cell surface CD4). Specific killing of infected cells can be blocked by rgp120, rCD4, or a monoclonal antibody to the gp120 binding site on CD4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Till, M A -- Ghetie, V -- Gregory, T -- Patzer, E J -- Porter, J P -- Uhr, J W -- Capon, D J -- Vitetta, E S -- CA-09082/CA/NCI NIH HHS/ -- CA-28149/CA/NCI NIH HHS/ -- CA-41081/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Nov 25;242(4882):1166-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas Southwestern Medical Center, Dallas 75235.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2847316" target="_blank"〉PubMed〈/a〉

    Description: The current model of apoptosis holds that upstream signals lead to activation of downstream effector caspases. We generated mice deficient in the two effectors, caspase 3 and caspase 7, which died immediately after birth with defects in cardiac development. Fibroblasts lacking both enzymes were highly resistant to both mitochondrial and death receptor-mediated apoptosis, displayed preservation of mitochondrial membrane potential, and had defective nuclear translocation of apoptosis-inducing factor (AIF). Furthermore, the early apoptotic events of Bax translocation and cytochrome c release were also delayed. We conclude that caspases 3 and 7 are critical mediators of mitochondrial events of apoptosis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3738210/" 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/PMC3738210/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lakhani, Saquib A -- Masud, Ali -- Kuida, Keisuke -- Porter, George A Jr -- Booth, Carmen J -- Mehal, Wajahat Z -- Inayat, Irteza -- Flavell, Richard A -- 1 K08 HD044580/HD/NICHD NIH HHS/ -- 5 K12 HD01401/HD/NICHD NIH HHS/ -- K08 DK002965/DK/NIDDK NIH HHS/ -- K08 DK002965-04/DK/NIDDK NIH HHS/ -- K12 HD00850/HD/NICHD NIH HHS/ -- NIDDK P30-34989/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):847-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Immunobiology, 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/16469926" target="_blank"〉PubMed〈/a〉

    Description: Network science is an interdisciplinary endeavor, with methods and applications drawn from across the natural, social, and information sciences. A prominent problem in network science is the algorithmic detection of tightly connected groups of nodes known as communities. We developed a generalized framework of network quality functions that allowed us to study the community structure of arbitrary multislice networks, which are combinations of individual networks coupled through links that connect each node in one network slice to itself in other slices. This framework allows studies of community structure in a general setting encompassing networks that evolve over time, have multiple types of links (multiplexity), and have multiple scales.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mucha, Peter J -- Richardson, Thomas -- Macon, Kevin -- Porter, Mason A -- Onnela, Jukka-Pekka -- New York, N.Y. -- Science. 2010 May 14;328(5980):876-8. doi: 10.1126/science.1184819.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Carolina Center for Interdisciplinary Applied Mathematics, Department of Mathematics, University of North Carolina, Chapel Hill, NC 27599, USA. mucha@unc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20466926" target="_blank"〉PubMed〈/a〉

    Description: 5-Methylthioadenosine phosphorylase (MTAP) is a key enzyme in the methionine salvage pathway. The MTAP gene is frequently deleted in human cancers because of its chromosomal proximity to the tumor suppressor gene CDKN2A. By interrogating data from a large-scale short hairpin RNA-mediated screen across 390 cancer cell line models, we found that the viability of MTAP-deficient cancer cells is impaired by depletion of the protein arginine methyltransferase PRMT5. MTAP-deleted cells accumulate the metabolite methylthioadenosine (MTA), which we found to inhibit PRMT5 methyltransferase activity. Deletion of MTAP in MTAP-proficient cells rendered them sensitive to PRMT5 depletion. Conversely, reconstitution of MTAP in an MTAP-deficient cell line rescued PRMT5 dependence. Thus, MTA accumulation in MTAP-deleted cancers creates a hypomorphic PRMT5 state that is selectively sensitized toward further PRMT5 inhibition. Inhibitors of PRMT5 that leverage this dysregulated metabolic state merit further investigation as a potential therapy for MTAP/CDKN2A-deleted tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mavrakis, Konstantinos J -- McDonald, E Robert 3rd -- Schlabach, Michael R -- Billy, Eric -- Hoffman, Gregory R -- deWeck, Antoine -- Ruddy, David A -- Venkatesan, Kavitha -- Yu, Jianjun -- McAllister, Gregg -- Stump, Mark -- deBeaumont, Rosalie -- Ho, Samuel -- Yue, Yingzi -- Liu, Yue -- Yan-Neale, Yan -- Yang, Guizhi -- Lin, Fallon -- Yin, Hong -- Gao, Hui -- Kipp, D Randal -- Zhao, Songping -- McNamara, Joshua T -- Sprague, Elizabeth R -- Zheng, Bing -- Lin, Ying -- Cho, Young Shin -- Gu, Justin -- Crawford, Kenneth -- Ciccone, David -- Vitari, Alberto C -- Lai, Albert -- Capka, Vladimir -- Hurov, Kristen -- Porter, Jeffery A -- Tallarico, John -- Mickanin, Craig -- Lees, Emma -- Pagliarini, Raymond -- Keen, Nicholas -- Schmelzle, Tobias -- Hofmann, Francesco -- Stegmeier, Frank -- Sellers, William R -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1208-13. doi: 10.1126/science.aad5944.
