Description: Severe behavioural deficits in psychiatric diseases such as autism and schizophrenia have been hypothesized to arise from elevations in the cellular balance of excitation and inhibition (E/I balance) within neural microcircuitry. This hypothesis could unify diverse streams of pathophysiological and genetic evidence, but has not been susceptible to direct testing. Here we design and use several novel optogenetic tools to causally investigate the cellular E/I balance hypothesis in freely moving mammals, and explore the associated circuit physiology. Elevation, but not reduction, of cellular E/I balance within the mouse medial prefrontal cortex was found to elicit a profound impairment in cellular information processing, associated with specific behavioural impairments and increased high-frequency power in the 30-80 Hz range, which have both been observed in clinical conditions in humans. Consistent with the E/I balance hypothesis, compensatory elevation of inhibitory cell excitability partially rescued social deficits caused by E/I balance elevation. These results provide support for the elevated cellular E/I balance hypothesis of severe neuropsychiatric disease-related symptoms.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4155501/" 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/PMC4155501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yizhar, Ofer -- Fenno, Lief E -- Prigge, Matthias -- Schneider, Franziska -- Davidson, Thomas J -- O'Shea, Daniel J -- Sohal, Vikaas S -- Goshen, Inbal -- Finkelstein, Joel -- Paz, Jeanne T -- Stehfest, Katja -- Fudim, Roman -- Ramakrishnan, Charu -- Huguenard, John R -- Hegemann, Peter -- Deisseroth, Karl -- DP1 OD000616/OD/NIH HHS/ -- R01 MH075957/MH/NIMH NIH HHS/ -- R01 MH086373/MH/NIMH NIH HHS/ -- R01 NS006477/NS/NINDS NIH HHS/ -- R01 NS034774/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Jul 27;477(7363):171-8. doi: 10.1038/nature10360.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, Stanford University, Stanford, California, USA. ofer.yizhar@weizmann.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21796121" target="_blank"〉PubMed〈/a〉

Description: Ependymomas are common childhood brain tumours that occur throughout the nervous system, but are most common in the paediatric hindbrain. Current standard therapy comprises surgery and radiation, but not cytotoxic chemotherapy as it does not further increase survival. Whole-genome and whole-exome sequencing of 47 hindbrain ependymomas reveals an extremely low mutation rate, and zero significant recurrent somatic single nucleotide variants. Although devoid of recurrent single nucleotide variants and focal copy number aberrations, poor-prognosis hindbrain ependymomas exhibit a CpG island methylator phenotype. Transcriptional silencing driven by CpG methylation converges exclusively on targets of the Polycomb repressive complex 2 which represses expression of differentiation genes through trimethylation of H3K27. CpG island methylator phenotype-positive hindbrain ependymomas are responsive to clinical drugs that target either DNA or H3K27 methylation both in vitro and in vivo. We conclude that epigenetic modifiers are the first rational therapeutic candidates for this deadly malignancy, which is epigenetically deregulated but genetically bland.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4174313/" 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/PMC4174313/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mack, S C -- Witt, H -- Piro, R M -- Gu, L -- Zuyderduyn, S -- Stutz, A M -- Wang, X -- Gallo, M -- Garzia, L -- Zayne, K -- Zhang, X -- Ramaswamy, V -- Jager, N -- Jones, D T W -- Sill, M -- Pugh, T J -- Ryzhova, M -- Wani, K M -- Shih, D J H -- Head, R -- Remke, M -- Bailey, S D -- Zichner, T -- Faria, C C -- Barszczyk, M -- Stark, S -- Seker-Cin, H -- Hutter, S -- Johann, P -- Bender, S -- Hovestadt, V -- Tzaridis, T -- Dubuc, A M -- Northcott, P A -- Peacock, J -- Bertrand, K C -- Agnihotri, S -- Cavalli, F M G -- Clarke, I -- Nethery-Brokx, K -- Creasy, C L -- Verma, S K -- Koster, J -- Wu, X -- Yao, Y -- Milde, T -- Sin-Chan, P -- Zuccaro, J -- Lau, L -- Pereira, S -- Castelo-Branco, P -- Hirst, M -- Marra, M A -- Roberts, S S -- Fults, D -- Massimi, L -- Cho, Y J -- Van Meter, T -- Grajkowska, W -- Lach, B -- Kulozik, A E -- von Deimling, A -- Witt, O -- Scherer, S W -- Fan, X -- Muraszko, K M -- Kool, M -- Pomeroy, S L -- Gupta, N -- Phillips, J -- Huang, A -- Tabori, U -- Hawkins, C -- Malkin, D -- Kongkham, P N -- Weiss, W A -- Jabado, N -- Rutka, J T -- Bouffet, E -- Korbel, J O -- Lupien, M -- Aldape, K D -- Bader, G D -- Eils, R -- Lichter, P -- Dirks, P B -- Pfister, S M -- Korshunov, A -- Taylor, M D -- P30 CA016672/CA/NCI NIH HHS/ -- P50 CA097257/CA/NCI NIH HHS/ -- R01 CA121941/CA/NCI NIH HHS/ -- R01 CA148621/CA/NCI NIH HHS/ -- R01 CA163737/CA/NCI NIH HHS/ -- R01CA148699/CA/NCI NIH HHS/ -- R01CA159859/CA/NCI NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2014 Feb 27;506(7489):445-50. doi: 10.1038/nature13108.

Description: Regulated transcription controls the diversity, developmental pathways and spatial organization of the hundreds of cell types that make up a mammal. Using single-molecule cDNA sequencing, we mapped transcription start sites (TSSs) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of mammalian gene expression across the human body. We find that few genes are truly 'housekeeping', whereas many mammalian promoters are composite entities composed of several closely separated TSSs, with independent cell-type-specific expression profiles. TSSs specific to different cell types evolve at different rates, whereas promoters of broadly expressed genes are the most conserved. Promoter-based expression analysis reveals key transcription factors defining cell states and links them to binding-site motifs. The functions of identified novel transcripts can be predicted by coexpression and sample ontology enrichment analyses. The functional annotation of the mammalian genome 5 (FANTOM5) project provides comprehensive expression profiles and functional annotation of mammalian cell-type-specific transcriptomes with wide applications in biomedical research.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4529748/" target="_blank"〉〈img

Description: After calcium silicate amendment to an entire watershed at the Hubbard Brook Experimental Forest, evapotranspiration (ET) increased by ∼20% for 2 y, broadly attributed to a fertilization of tree physiology (1). We suggested that the increase in ET most likely arose from enhanced transpiration due to increased stomatal conductance (gs)...

Description: The study by Newsome et al. (1) presented an approach to evaluating the historic ecological role of bald eagles (Haliaeetus leucocephalus) on the California Channel Islands (CI). Unfortunately, they ignore an alternative explanation for some of their data and overinterpret their results, leading to conclusions that are not the most parsimonious (1).First, Newsome et al. (1) incorrectly dismissed two prehistoric eagles with a stable isotope signature, suggesting “heavy reliance on terrestrial prey” as “migrants from the mainland.” They do so by arguing that large terrestrial prey would not have been available to resident CI eagles when their specimens were preserved....

Description: Goldfeld et al. (1) presented modeling results on restoring 3D structures of the intra- and extracellular loops in bovine rhodopsin (bRh), human A2A adenosine receptor (A2Ar), turkey β1-adrenergic receptor (β1AR), and human β2-adrenergic receptor (β2AR). In all cases, the lowest energy conformers of the loops matched the corresponding X-ray structures with excellent rmsd values. The extracellular loops for the same receptors were modeled in our article previously (2) with the use of a much less sophisticated modeling procedure. Goldfeld et al. (1) emphasized substantially better accuracy of reproducing the X-ray structures of the loops, especially larger loops, in their study...

Description: Lincoln et al. (1) claim that Marine Group II Euryarchaeota (MG-II) are significant contributors to glycerol dibiphytanyl glycerol tetraether (GDGT) lipids in the ocean and biosynthesize crenarchaeol, a membrane lipid generally attributed to Thaumarchaeota (MG-I). The authors present two lines of convergent evidence for their far-reaching claim. The first line...

Description: We developed a nonhuman primate model to study whether pertussis vaccination is able to disrupt Bordetella pertussis colonization and transmission, and demonstrated that baboons vaccinated with the acellular pertussis vaccines (aP) were protected from classic pertussis symptoms (i.e., coughing and leukocytosis) but were highly colonized and transmitted pertussis to contacts...

Description: The E2F family is conserved from Caenorhabditis elegans to mammals, with some family members having transcription activation functions and others having repressor functions. Whereas C. elegans and Drosophila melanogaster have a single E2F activator protein and repressor protein, mammals have at least three activator and five repressor proteins. Why such genetic complexity evolved in mammals is not known. To begin to evaluate this genetic complexity, we targeted the inactivation of the entire subset of activators, E2f1, E2f2, E2f3a and E2f3b, singly or in combination in mice. We demonstrate that E2f3a is sufficient to support mouse embryonic and postnatal development. Remarkably, expression of E2f3b or E2f1 from the E2f3a locus (E2f3a(3bki) or E2f3a(1ki), respectively) suppressed all the postnatal phenotypes associated with the inactivation of E2f3a. We conclude that there is significant functional redundancy among activators and that the specific requirement for E2f3a during postnatal development is dictated by regulatory sequences governing its selective spatiotemporal expression and not by its intrinsic protein functions. These findings provide a molecular basis for the observed specificity among E2F activators during development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4288824/" 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/PMC4288824/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Shih-Yin -- Opavsky, Rene -- Sharma, Nidhi -- Wu, Lizhao -- Naidu, Shan -- Nolan, Eric -- Feria-Arias, Enrique -- Timmers, Cynthia -- Opavska, Jana -- de Bruin, Alain -- Chong, Jean-Leon -- Trikha, Prashant -- Fernandez, Soledad A -- Stromberg, Paul -- Rosol, Thomas J -- Leone, Gustavo -- K01CA102328/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA121275/CA/NCI NIH HHS/ -- R01 CA121275-03/CA/NCI NIH HHS/ -- R01CA121275/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD042619/HD/NICHD NIH HHS/ -- R01HD047470/HD/NICHD NIH HHS/ -- T32CA106196/CA/NCI NIH HHS/ -- England -- Nature. 2008 Aug 28;454(7208):1137-41. doi: 10.1038/nature07066.
