    Description: We have identified a small-molecule inhibitor of tumor necrosis factor alpha (TNF-alpha) that promotes subunit disassembly of this trimeric cytokine family member. The compound inhibits TNF-alpha activity in biochemical and cell-based assays with median inhibitory concentrations of 22 and 4.6 micromolar, respectively. Formation of an intermediate complex between the compound and the intact trimer results in a 600-fold accelerated subunit dissociation rate that leads to trimer dissociation. A structure solved by x-ray crystallography reveals that a single compound molecule displaces a subunit of the trimer to form a complex with a dimer of TNF-alpha subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Molly M -- Smith, Annemarie Stroustrup -- Oslob, Johan D -- Flanagan, William M -- Braisted, Andrew C -- Whitty, Adrian -- Cancilla, Mark T -- Wang, Jun -- Lugovskoy, Alexey A -- Yoburn, Josh C -- Fung, Amy D -- Farrington, Graham -- Eldredge, John K -- Day, Eric S -- Cruz, Leslie A -- Cachero, Teresa G -- Miller, Stephan K -- Friedman, Jessica E -- Choong, Ingrid C -- Cunningham, Brian C -- New York, N.Y. -- Science. 2005 Nov 11;310(5750):1022-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sunesis Pharmaceuticals, Incorporated, 341 Oyster Point Boulevard, South San Francisco, CA 94080, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16284179" target="_blank"〉PubMed〈/a〉

    Description: H5N1 avian influenza virus (AIV) has emerged as a pathogenic entity for a variety of species, including humans, in recent years. Here we report an outbreak among migratory birds on Lake Qinghaihu, China, in May and June 2005, in which more than a thousand birds were affected. Pancreatic necrosis and abnormal neurological symptoms were the major clinical features. Sequencing of the complete genomes of four H5N1 AIV strains revealed them to be reassortants related to a peregrine falcon isolate from Hong Kong and to have known highly pathogenic characteristics. Experimental animal infections reproduced typical highly pathogenic AIV infection symptoms and pathology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, J -- Xiao, H -- Lei, F -- Zhu, Q -- Qin, K -- Zhang, X-W -- Zhang, X-L -- Zhao, D -- Wang, G -- Feng, Y -- Ma, J -- Liu, W -- Wang, J -- Gao, G F -- New York, N.Y. -- Science. 2005 Aug 19;309(5738):1206.

    Description: Lithium is commonly used to treat bipolar disorder, which is associated with altered circadian rhythm. Lithium is a potent inhibitor of glycogen synthase kinase 3 (GSK3), which regulates circadian rhythm in several organisms. In experiments with cultured cells, we show here that GSK3beta phosphorylates and stabilizes the orphan nuclear receptor Rev-erbalpha, a negative component of the circadian clock. Lithium treatment of cells leads to rapid proteasomal degradation of Rev-erbalpha and activation of clock gene Bmal1. A form of Rev-erbalpha that is insensitive to lithium interferes with the expression of circadian genes. Control of Rev-erbalpha protein stability is thus a critical component of the peripheral clock and a biological target of lithium therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yin, Lei -- Wang, Jing -- Klein, Peter S -- Lazar, Mitchell A -- DK 19525/DK/NIDDK NIH HHS/ -- DK45586/DK/NIDDK NIH HHS/ -- MH058324/MH/NIMH NIH HHS/ -- R01 MH058324/MH/NIMH NIH HHS/ -- R01 MH058324-07/MH/NIMH NIH HHS/ -- R01 MH058324-08/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1002-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology, Diabetes, and Metabolism, and University of Pennsylvania School of Medicine, 415 Curie Boulevard, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484495" target="_blank"〉PubMed〈/a〉

    Description: The mammalian target of rapamycin, mTOR, is a central regulator of cell growth. Its activity is regulated by Rheb, a Ras-like small guanosine triphosphatase (GTPase), in response to growth factor stimulation and nutrient availability. We show that Rheb regulates mTOR through FKBP38, a member of the FK506-binding protein (FKBP) family that is structurally related to FKBP12. FKBP38 binds to mTOR and inhibits its activity in a manner similar to that of the FKBP12-rapamycin complex. Rheb interacts directly with FKBP38 and prevents its association with mTOR in a guanosine 5'-triphosphate (GTP)-dependent manner. Our findings suggest that FKBP38 is an endogenous inhibitor of mTOR, whose inhibitory activity is antagonized by Rheb in response to growth factor stimulation and nutrient availability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bai, Xiaochun -- Ma, Dongzhu -- Liu, Anling -- Shen, Xiaoyun -- Wang, Qiming J -- Liu, Yongjian -- Jiang, Yu -- GM068832/GM/NIGMS NIH HHS/ -- R01 CA129821/CA/NCI NIH HHS/ -- R01 GM068832/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 9;318(5852):977-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Pittsburgh School of Medicine, E1357 Biomedical Science Tower, 200 Lothrop Street, Pittsburgh, PA 15213, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17991864" target="_blank"〉PubMed〈/a〉

    Description: Chromosomal rearrangements that create gene fusions are common features of human tumors. The prevailing view is that the resultant chimeric transcripts and proteins are abnormal, tumor-specific products that provide tumor cells with a growth and/or survival advantage. We show that normal endometrial stromal cells contain a specific chimeric RNA joining 5' exons of the JAZF1 gene on chromosome 7p15 to 3' exons of the Polycomb group gene JJAZ1/SUZ12 on chromosome 17q11 and that this RNA is translated into JAZF1-JJAZ1, a protein with anti-apoptotic activity. The JAZF1-JJAZ1 RNA appears to arise from physiologically regulated trans-splicing between precursor messenger RNAs for JAZF1 and JJAZ1. The chimeric RNA and protein are identical to those produced from a gene fusion found in human endometrial stromal tumors. These observations suggest that certain gene fusions may be pro-neoplastic owing to constitutive expression of chimeric gene products normally generated by trans-splicing of RNAs in developing tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Hui -- Wang, Jinglan -- Mor, Gil -- Sklar, Jeffrey -- R01 CA85995/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1357-61. doi: 10.1126/science.1156725.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, 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/18772439" target="_blank"〉PubMed〈/a〉

    Description: Measurements of the abundance of common metabolites in cultured embryonic stem (ES) cells revealed an unusual state with respect to one-carbon metabolism. These findings led to the discovery of copious expression of the gene encoding threonine dehydrogenase (TDH) in ES cells. TDH-mediated catabolism of threonine takes place in mitochondria to generate glycine and acetyl-coenzyme A (CoA), with glycine facilitating one-carbon metabolism via the glycine cleavage system and acetyl-CoA feeding the tricarboxylic acid cycle. Culture media individually deprived of each of the 20 amino acids were applied to ES cells, leading to the discovery that ES cells are critically dependent on one amino acid--threonine. These observations show that ES cells exist in a high-flux backbone metabolic state comparable to that of rapidly growing bacterial cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4373593/" 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/PMC4373593/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Jian -- Alexander, Peter -- Wu, Leeju -- Hammer, Robert -- Cleaver, Ondine -- McKnight, Steven L -- R01 DK079862/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):435-9. doi: 10.1126/science.1173288.

    Description: Akt signaling plays a central role in many biological functions, such as cell proliferation and apoptosis. Because Akt (also known as protein kinase B) resides primarily in the cytosol, it is not known how these signaling molecules are recruited to the plasma membrane and subsequently activated by growth factor stimuli. We found that the protein kinase Akt undergoes lysine-63 chain ubiquitination, which is important for Akt membrane localization and phosphorylation. TRAF6 was found to be a direct E3 ligase for Akt and was essential for Akt ubiquitination, membrane recruitment, and phosphorylation upon growth-factor stimulation. The human cancer-associated Akt mutant displayed an increase in Akt ubiquitination, in turn contributing to the enhancement of Akt membrane localization and phosphorylation. Thus, Akt ubiquitination is an important step for oncogenic Akt activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3008763/" 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/PMC3008763/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Wei-Lei -- Wang, Jing -- Chan, Chia-Hsin -- Lee, Szu-Wei -- Campos, Alejandro D -- Lamothe, Betty -- Hur, Lana -- Grabiner, Brian C -- Lin, Xin -- Darnay, Bryant G -- Lin, Hui-Kuan -- R01 CA149321/CA/NCI NIH HHS/ -- R01 CA149321-02/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 28;325(5944):1134-8. doi: 10.1126/science.1175065.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Oncology, The University of Texas M.
