    Description: Platelets are the second most abundant cell type in blood and are essential for maintaining haemostasis. Their count and volume are tightly controlled within narrow physiological ranges, but there is only limited understanding of the molecular processes controlling both traits. Here we carried out a high-powered meta-analysis of genome-wide association studies (GWAS) in up to 66,867 individuals of European ancestry, followed by extensive biological and functional assessment. We identified 68 genomic loci reliably associated with platelet count and volume mapping to established and putative novel regulators of megakaryopoiesis and platelet formation. These genes show megakaryocyte-specific gene expression patterns and extensive network connectivity. Using gene silencing in Danio rerio and Drosophila melanogaster, we identified 11 of the genes as novel regulators of blood cell formation. Taken together, our findings advance understanding of novel gene functions controlling fate-determining events during megakaryopoiesis and platelet formation, providing a new example of successful translation of GWAS to function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3335296/" target="_blank"〉〈img

    Description: The Arabidopsis thaliana protein UVR8 is a photoreceptor for ultraviolet-B. Upon ultraviolet-B irradiation, UVR8 undergoes an immediate switch from homodimer to monomer, which triggers a signalling pathway for ultraviolet protection. The mechanism by which UVR8 senses ultraviolet-B remains largely unknown. Here we report the crystal structure of UVR8 at 1.8 A resolution, revealing a symmetric homodimer of seven-bladed beta-propeller that is devoid of any external cofactor as the chromophore. Arginine residues that stabilize the homodimeric interface, principally Arg 286 and Arg 338, make elaborate intramolecular cation-pi interactions with surrounding tryptophan amino acids. Two of these tryptophans, Trp 285 and Trp 233, collectively serve as the ultraviolet-B chromophore. Our structural and biochemical analyses identify the molecular mechanism for UVR8-mediated ultraviolet-B perception, in which ultraviolet-B radiation results in destabilization of the intramolecular cation-pi interactions, causing disruption of the critical intermolecular hydrogen bonds mediated by Arg 286 and Arg 338 and subsequent dissociation of the UVR8 homodimer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Di -- Hu, Qi -- Yan, Zhen -- Chen, Wen -- Yan, Chuangye -- Huang, Xi -- Zhang, Jing -- Yang, Panyu -- Deng, Haiteng -- Wang, Jiawei -- Deng, XingWang -- Shi, Yigong -- R37 GM047850/GM/NIGMS NIH HHS/ -- England -- Nature. 2012 Feb 29;484(7393):214-9. doi: 10.1038/nature10931.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tsinghua-Peking Center for Life Sciences, Center for Structural Biology, School of Life Sciences and School of Medicine, Tsinghua University, Beijing 100084, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22388820" target="_blank"〉PubMed〈/a〉

    Description: Improved sequencing technologies offer unprecedented opportunities for investigating the role of rare genetic variation in common disease. However, there are considerable challenges with respect to study design, data analysis and replication. Using pooled next-generation sequencing of 507 genes implicated in the repair of DNA in 1,150 samples, an analytical strategy focused on protein-truncating variants (PTVs) and a large-scale sequencing case-control replication experiment in 13,642 individuals, here we show that rare PTVs in the p53-inducible protein phosphatase PPM1D are associated with predisposition to breast cancer and ovarian cancer. PPM1D PTV mutations were present in 25 out of 7,781 cases versus 1 out of 5,861 controls (P = 1.12 x 10(-5)), including 18 mutations in 6,912 individuals with breast cancer (P = 2.42 x 10(-4)) and 12 mutations in 1,121 individuals with ovarian cancer (P = 3.10 x 10(-9)). Notably, all of the identified PPM1D PTVs were mosaic in lymphocyte DNA and clustered within a 370-base-pair region in the final exon of the gene, carboxy-terminal to the phosphatase catalytic domain. Functional studies demonstrate that the mutations result in enhanced suppression of p53 in response to ionizing radiation exposure, suggesting that the mutant alleles encode hyperactive PPM1D isoforms. Thus, although the mutations cause premature protein truncation, they do not result in the simple loss-of-function effect typically associated with this class of variant, but instead probably have a gain-of-function effect. Our results have implications for the detection and management of breast and ovarian cancer risk. More generally, these data provide new insights into the role of rare and of mosaic genetic variants in common conditions, and the use of sequencing in their identification.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3759028/" 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/PMC3759028/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruark, Elise -- Snape, Katie -- Humburg, Peter -- Loveday, Chey -- Bajrami, Ilirjana -- Brough, Rachel -- Rodrigues, Daniel Nava -- Renwick, Anthony -- Seal, Sheila -- Ramsay, Emma -- Duarte, Silvana Del Vecchio -- Rivas, Manuel A -- Warren-Perry, Margaret -- Zachariou, Anna -- Campion-Flora, Adriana -- Hanks, Sandra -- Murray, Anne -- Ansari Pour, Naser -- Douglas, Jenny -- Gregory, Lorna -- Rimmer, Andrew -- Walker, Neil M -- Yang, Tsun-Po -- Adlard, Julian W -- Barwell, Julian -- Berg, Jonathan -- Brady, Angela F -- Brewer, Carole -- Brice, Glen -- Chapman, Cyril -- Cook, Jackie -- Davidson, Rosemarie -- Donaldson, Alan -- Douglas, Fiona -- Eccles, Diana -- Evans, D Gareth -- Greenhalgh, Lynn -- Henderson, Alex -- Izatt, Louise -- Kumar, Ajith -- Lalloo, Fiona -- Miedzybrodzka, Zosia -- Morrison, Patrick J -- Paterson, Joan -- Porteous, Mary -- Rogers, Mark T -- Shanley, Susan -- Walker, Lisa -- Gore, Martin -- Houlston, Richard -- Brown, Matthew A -- Caufield, Mark J -- Deloukas, Panagiotis -- McCarthy, Mark I -- Todd, John A -- Breast and Ovarian Cancer Susceptibility Collaboration -- Wellcome Trust Case Control Consortium -- Turnbull, Clare -- Reis-Filho, Jorge S -- Ashworth, Alan -- Antoniou, Antonis C -- Lord, Christopher J -- Donnelly, Peter -- Rahman, Nazneen -- 068545/Z/02/Wellcome Trust/United Kingdom -- 083948/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 090532/Z/09/Z/Wellcome Trust/United Kingdom -- 091157/Wellcome Trust/United Kingdom -- 095552/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 100140/Wellcome Trust/United Kingdom -- 11174/Cancer Research UK/United Kingdom -- C12292/A11174/Cancer Research UK/United Kingdom -- CZB/4/540/Chief Scientist Office/United Kingdom -- ETM/137/Chief Scientist Office/United Kingdom -- ETM/75/Chief Scientist Office/United Kingdom -- G0000934/Medical Research Council/United Kingdom -- G0600329/Medical Research Council/United Kingdom -- G0800759/Medical Research Council/United Kingdom -- G0900747 91070/Medical Research Council/United Kingdom -- G9521010/Medical Research Council/United Kingdom -- MR/K006584/1/Medical Research Council/United Kingdom -- England -- Nature. 2013 Jan 17;493(7432):406-10. doi: 10.1038/nature11725.

    Description: The binding site for DETQ [2-(2,6-dichlorophenyl)-1-((1 S ,3 R )-3-(hydroxymethyl)-5-(2-hydroxypropan-2-yl)-1-methyl-3,4-dihydroisoquinolin-2(1 H )-yl)ethan-1-one], a positive allosteric modulator (PAM) of the dopamine D1 receptor, was identified and compared with the binding site for CID 2886111 [ N -(6- tert -butyl-3-carbamoyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl)pyridine-4-carboxamide], a reference D1 PAM. From D1/D5 chimeras, the site responsible for potentiation by DETQ of the increase in cAMP in response to dopamine was narrowed down to the N-terminal intracellular quadrant of the receptor; arginine-130 in intracellular loop 2 (IC2) was then identified as a critical amino acid based on a human/rat species difference. Confirming the importance of IC2, a β 2-adrenergic receptor construct in which the IC2 region was replaced with its D1 counterpart gained the ability to respond to DETQ. A homology model was built from the agonist-state β 2-receptor structure, and DETQ was found to dock to a cleft created by IC2 and adjacent portions of transmembrane helices 3 and 4 (TM3 and TM4). When residues modeled as pointing into the cleft were mutated to alanine, large reductions in the potency of DETQ were found for Val119 and Trp123 (flanking the conserved DRY sequence in TM3), Arg130 (located in IC2), and Leu143 (TM4). The D1/D5 difference was found to reside in Ala139; changing this residue to methionine as in the D5 receptor reduced the potency of DETQ by approximately 1000-fold. None of these mutations affected the activity of CID 2886111, indicating that it binds to a different allosteric site. When combined, DETQ and CID 2886111 elicited a supra-additive response in the absence of dopamine, implying that both PAMs can bind to the D1 receptor simultaneously.

    Description: Loss of monoubiquitination of histone H2B (H2Bub1) was found to be associated with poor-differentiation and enhanced malignancy of lung adenocarcinoma. This study investigated the association and impact of the ubiquitin-specific peptidase 22 (USP22), an H2Bub1 deubiquitinase, on stem cell-like characteristics and cisplatin resistance in cancer-initiating cells (CIC) from primary lung adenocarcinoma. CICs were isolated, enriched, and characterized from patient-derived cancer tissues using both in vitro tumorsphere formation and in vivo xenograft assays. USP22 was determined to be predominantly expressed in CICs, a subpopulation of cells with high expression of the stem cell biomarkers, CD133 and CD44. The expression of USP22 in CICs is markedly reduced upon FBS/retinoic acid-induced differentiation. Moreover, knockdown of USP22 significantly suppressed tumorsphere formation and xenograft growth in NOD-SCID gamma (NSG) mice. Notably, USP22 and aldehyde dehydrogenase (ALDH) activity were elevated in tumorsphere cells that survived cisplatin treatment, whereas knockdown of USP22 significantly sensitizes tumorsphere cells to cisplatin. Interestingly, ALDH1A3, a predominant ALDH isozyme implicated in enhancing cisplatin resistance in lung adenocarcinoma, is significantly downregulated upon knockdown of USP22 in tumorsphere cells. Furthermore, knockdown of ALDH1A3 significantly sensitizes tumorsphere cells to cisplatin. Combined, these data demonstrate that USP22, predominantly expressed in CD133 + CICs, plays a critical role in tumorigenicity and cisplatin resistance in lung adenocarcinoma. Implications: Targeting USP22 represents a potential therapeutic approach to suppress CICs in lung adenocarcinoma partially through downregulation of ALDH1A3 expression.

    Description: DNA methylation is an important epigenetic modification. Ten-eleven translocation (TET) proteins are involved in DNA demethylation through iteratively oxidizing 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC). Here we show that human TET1 and TET2 are more active on 5mC-DNA than 5hmC/5fC-DNA substrates. We determine the crystal structures of TET2-5hmC-DNA and TET2-5fC-DNA complexes at 1.80 A and 1.97 A resolution, respectively. The cytosine portion of 5hmC/5fC is specifically recognized by TET2 in a manner similar to that of 5mC in the TET2-5mC-DNA structure, and the pyrimidine base of 5mC/5hmC/5fC adopts an almost identical conformation within the catalytic cavity. However, the hydroxyl group of 5hmC and carbonyl group of 5fC face towards the opposite direction because the hydroxymethyl group of 5hmC and formyl group of 5fC adopt restrained conformations through forming hydrogen bonds with the 1-carboxylate of NOG and N4 exocyclic nitrogen of cytosine, respectively. Biochemical analyses indicate that the substrate preference of TET2 results from the different efficiencies of hydrogen abstraction in TET2-mediated oxidation. The restrained conformation of 5hmC and 5fC within the catalytic cavity may prevent their abstractable hydrogen(s) adopting a favourable orientation for hydrogen abstraction and thus result in low catalytic efficiency. Our studies demonstrate that the substrate preference of TET2 results from the intrinsic value of its substrates at their 5mC derivative groups and suggest that 5hmC is relatively stable and less prone to further oxidation by TET proteins. Therefore, TET proteins are evolutionarily tuned to be less reactive towards 5hmC and facilitate the generation of 5hmC as a potentially stable mark for regulatory functions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Lulu -- Lu, Junyan -- Cheng, Jingdong -- Rao, Qinhui -- Li, Ze -- Hou, Haifeng -- Lou, Zhiyong -- Zhang, Lei -- Li, Wei -- Gong, Wei -- Liu, Mengjie -- Sun, Chang -- Yin, Xiaotong -- Li, Jie -- Tan, Xiangshi -- Wang, Pengcheng -- Wang, Yinsheng -- Fang, Dong -- Cui, Qiang -- Yang, Pengyuan -- He, Chuan -- Jiang, Hualiang -- Luo, Cheng -- Xu, Yanhui -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Nov 5;527(7576):118-22. doi: 10.1038/nature15713.

    Description: The Hippo signaling pathway regulates organ size and plays critical roles in maintaining tissue growth, homeostasis, and regeneration. Dysregulated in a wide spectrum of cancers, in mammals, this pathway is regulated by two key effectors, YAP and TAZ, that may functionally overlap. We found that TAZ promoted liver inflammation and tumor development. The expression of TAZ, but not YAP, in human liver tumors positively correlated with the expression of proinflammatory cytokines. Hyperactivated TAZ induced substantial myeloid cell infiltration into the liver and the secretion of proinflammatory cytokines through a TEAD-dependent mechanism. Furthermore, tumors with hyperactivated YAP and TAZ had distinct transcriptional signatures, which included the increased expression of inflammatory cytokines in TAZ-driven tumors. Our study elucidated a previously uncharacterized link between TAZ activity and inflammatory responses that influence tumor development in the liver.

    Description: Despite progress in defining genetic risk for psychiatric disorders, their molecular mechanisms remain elusive. Addressing this, the PsychENCODE Consortium has generated a comprehensive online resource for the adult brain across 1866 individuals. The PsychENCODE resource contains ~79,000 brain-active enhancers, sets of Hi-C linkages, and topologically associating domains; single-cell expression profiles for many cell types; expression quantitative-trait loci (QTLs); and further QTLs associated with chromatin, splicing, and cell-type proportions. Integration shows that varying cell-type proportions largely account for the cross-population variation in expression (with 〉88% reconstruction accuracy). It also allows building of a gene regulatory network, linking genome-wide association study variants to genes (e.g., 321 for schizophrenia). We embed this network into an interpretable deep-learning model, which improves disease prediction by ~6-fold versus polygenic risk scores and identifies key genes and pathways in psychiatric disorders.

    Description: 'Orang-utan' is derived from a Malay term meaning 'man of the forest' and aptly describes the southeast Asian great apes native to Sumatra and Borneo. The orang-utan species, Pongo abelii (Sumatran) and Pongo pygmaeus (Bornean), are the most phylogenetically distant great apes from humans, thereby providing an informative perspective on hominid evolution. Here we present a Sumatran orang-utan draft genome assembly and short read sequence data from five Sumatran and five Bornean orang-utan genomes. Our analyses reveal that, compared to other primates, the orang-utan genome has many unique features. Structural evolution of the orang-utan genome has proceeded much more slowly than other great apes, evidenced by fewer rearrangements, less segmental duplication, a lower rate of gene family turnover and surprisingly quiescent Alu repeats, which have played a major role in restructuring other primate genomes. We also describe a primate polymorphic neocentromere, found in both Pongo species, emphasizing the gradual evolution of orang-utan genome structure. Orang-utans have extremely low energy usage for a eutherian mammal, far lower than their hominid relatives. Adding their genome to the repertoire of sequenced primates illuminates new signals of positive selection in several pathways including glycolipid metabolism. From the population perspective, both Pongo species are deeply diverse; however, Sumatran individuals possess greater diversity than their Bornean counterparts, and more species-specific variation. Our estimate of Bornean/Sumatran speciation time, 400,000 years ago, is more recent than most previous studies and underscores the complexity of the orang-utan speciation process. Despite a smaller modern census population size, the Sumatran effective population size (N(e)) expanded exponentially relative to the ancestral N(e) after the split, while Bornean N(e) declined over the same period. Overall, the resources and analyses presented here offer new opportunities in evolutionary genomics, insights into hominid biology, and an extensive database of variation for conservation efforts.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3060778/" 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/PMC3060778/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Locke, Devin P -- Hillier, LaDeana W -- Warren, Wesley C -- Worley, Kim C -- Nazareth, Lynne V -- Muzny, Donna M -- Yang, Shiaw-Pyng -- Wang, Zhengyuan -- Chinwalla, Asif T -- Minx, Pat -- Mitreva, Makedonka -- Cook, Lisa -- Delehaunty, Kim D -- Fronick, Catrina -- Schmidt, Heather -- Fulton, Lucinda A -- Fulton, Robert S -- Nelson, Joanne O -- Magrini, Vincent -- Pohl, Craig -- Graves, Tina A -- Markovic, Chris -- Cree, Andy -- Dinh, Huyen H -- Hume, Jennifer -- Kovar, Christie L -- Fowler, Gerald R -- Lunter, Gerton -- Meader, Stephen -- Heger, Andreas -- Ponting, Chris P -- Marques-Bonet, Tomas -- Alkan, Can -- Chen, Lin -- Cheng, Ze -- Kidd, Jeffrey M -- Eichler, Evan E -- White, Simon -- Searle, Stephen -- Vilella, Albert J -- Chen, Yuan -- Flicek, Paul -- Ma, Jian -- Raney, Brian -- Suh, Bernard -- Burhans, Richard -- Herrero, Javier -- Haussler, David -- Faria, Rui -- Fernando, Olga -- Darre, Fleur -- Farre, Domenec -- Gazave, Elodie -- Oliva, Meritxell -- Navarro, Arcadi -- Roberto, Roberta -- Capozzi, Oronzo -- Archidiacono, Nicoletta -- Della Valle, Giuliano -- Purgato, Stefania -- Rocchi, Mariano -- Konkel, Miriam K -- Walker, Jerilyn A -- Ullmer, Brygg -- Batzer, Mark A -- Smit, Arian F A -- Hubley, Robert -- Casola, Claudio -- Schrider, Daniel R -- Hahn, Matthew W -- Quesada, Victor -- Puente, Xose S -- Ordonez, Gonzalo R -- Lopez-Otin, Carlos -- Vinar, Tomas -- Brejova, Brona -- Ratan, Aakrosh -- Harris, Robert S -- Miller, Webb -- Kosiol, Carolin -- Lawson, Heather A -- Taliwal, Vikas -- Martins, Andre L -- Siepel, Adam -- Roychoudhury, Arindam -- Ma, Xin -- Degenhardt, Jeremiah -- Bustamante, Carlos D -- Gutenkunst, Ryan N -- Mailund, Thomas -- Dutheil, Julien Y -- Hobolth, Asger -- Schierup, Mikkel H -- Ryder, Oliver A -- Yoshinaga, Yuko -- de Jong, Pieter J -- Weinstock, George M -- Rogers, Jeffrey -- Mardis, Elaine R -- Gibbs, Richard A -- Wilson, Richard K -- G0501331/Medical Research Council/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- HG002385/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 AG022064/AG/NIA NIH HHS/ -- R01 GM059290/GM/NIGMS NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-08/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2011 Jan 27;469(7331):529-33. doi: 10.1038/nature09687.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Center at Washington University, Washington University School of Medicine, 4444 Forest Park Avenue, Saint Louis, Missouri 63108, USA. dlocke@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21270892" target="_blank"〉PubMed〈/a〉
