    Association of TALS developmental disorder with defect in minor splicing component U4atac snRNA (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-09
    Description: The spliceosome, a ribonucleoprotein complex that includes proteins and small nuclear RNAs (snRNAs), catalyzes RNA splicing through intron excision and exon ligation to produce mature messenger RNAs, which, in turn serve as templates for protein translation. We identified four point mutations in the U4atac snRNA component of the minor spliceosome in patients with brain and bone malformations and unexplained postnatal death [microcephalic osteodysplastic primordial dwarfism type 1 (MOPD 1) or Taybi-Linder syndrome (TALS); Mendelian Inheritance in Man ID no. 210710]. Expression of a subgroup of genes, possibly linked to the disease phenotype, and minor intron splicing were affected in cell lines derived from TALS patients. Our findings demonstrate a crucial role of the minor spliceosome component U4atac snRNA in early human development and postnatal survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edery, Patrick -- Marcaillou, Charles -- Sahbatou, Mourad -- Labalme, Audrey -- Chastang, Joelle -- Touraine, Renaud -- Tubacher, Emmanuel -- Senni, Faiza -- Bober, Michael B -- Nampoothiri, Sheela -- Jouk, Pierre-Simon -- Steichen, Elisabeth -- Berland, Siren -- Toutain, Annick -- Wise, Carol A -- Sanlaville, Damien -- Rousseau, Francis -- Clerget-Darpoux, Francoise -- Leutenegger, Anne-Louise -- New York, N.Y. -- Science. 2011 Apr 8;332(6026):240-3. doi: 10.1126/science.1202205.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Hospices Civils de Lyon, Service de Cytogenetique Constitutionnelle, Bron, F-69677, France. patrick.edery@chu-lyon.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21474761" target="_blank"〉PubMed〈/a〉

    Spatial coupling of mTOR and autophagy augments secretory phenotypes (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-04-23
    Description: Protein synthesis and autophagic degradation are regulated in an opposite manner by mammalian target of rapamycin (mTOR), whereas under certain conditions it would be beneficial if they occurred in unison to handle rapid protein turnover. We observed a distinct cellular compartment at the trans side of the Golgi apparatus, the TOR-autophagy spatial coupling compartment (TASCC), where (auto)lysosomes and mTOR accumulated during Ras-induced senescence. mTOR recruitment to the TASCC was amino acid- and Rag guanosine triphosphatase-dependent, and disruption of mTOR localization to the TASCC suppressed interleukin-6/8 synthesis. TASCC formation was observed during macrophage differentiation and in glomerular podocytes; both displayed increased protein secretion. The spatial coupling of cells' catabolic and anabolic machinery could augment their respective functions and facilitate the mass synthesis of secretory proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3426290/" 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/PMC3426290/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Narita, Masako -- Young, Andrew R J -- Arakawa, Satoko -- Samarajiwa, Shamith A -- Nakashima, Takayuki -- Yoshida, Sei -- Hong, Sungki -- Berry, Lorraine S -- Reichelt, Stefanie -- Ferreira, Manuela -- Tavare, Simon -- Inoki, Ken -- Shimizu, Shigeomi -- Narita, Masashi -- DK083491/DK/NIDDK NIH HHS/ -- R01 DK083491/DK/NIDDK NIH HHS/ -- R01 DK083491-03/DK/NIDDK NIH HHS/ -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2011 May 20;332(6032):966-70. doi: 10.1126/science.1205407.

    Tet proteins can convert 5-methylcytosine to 5-formylcytosine and 5-carboxylcytosine (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-23
    Description: 5-methylcytosine (5mC) in DNA plays an important role in gene expression, genomic imprinting, and suppression of transposable elements. 5mC can be converted to 5-hydroxymethylcytosine (5hmC) by the Tet (ten eleven translocation) proteins. Here, we show that, in addition to 5hmC, the Tet proteins can generate 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) from 5mC in an enzymatic activity-dependent manner. Furthermore, we reveal the presence of 5fC and 5caC in genomic DNA of mouse embryonic stem cells and mouse organs. The genomic content of 5hmC, 5fC, and 5caC can be increased or reduced through overexpression or depletion of Tet proteins. Thus, we identify two previously unknown cytosine derivatives in genomic DNA as the products of Tet proteins. Our study raises the possibility that DNA demethylation may occur through Tet-catalyzed oxidation followed by decarboxylation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3495246/" 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/PMC3495246/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Shinsuke -- Shen, Li -- Dai, Qing -- Wu, Susan C -- Collins, Leonard B -- Swenberg, James A -- He, Chuan -- Zhang, Yi -- GM071440/GM/NIGMS NIH HHS/ -- GM68804/GM/NIGMS NIH HHS/ -- P30 ES010126/ES/NIEHS NIH HHS/ -- P30 ES010126-11/ES/NIEHS NIH HHS/ -- P30ES10126/ES/NIEHS NIH HHS/ -- P42 ES005948/ES/NIEHS NIH HHS/ -- P42 ES005948-17/ES/NIEHS NIH HHS/ -- P42ES5948/ES/NIEHS NIH HHS/ -- R01 GM068804/GM/NIGMS NIH HHS/ -- U01 DK089565/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Sep 2;333(6047):1300-3. doi: 10.1126/science.1210597.

    Cleavage of NIK by the API2-MALT1 fusion oncoprotein leads to noncanonical NF-kappaB activation (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-01-29
    Description: Proper regulation of nuclear factor kappaB (NF-kappaB) transcriptional activity is required for normal lymphocyte function, and deregulated NF-kappaB signaling can facilitate lymphomagenesis. We demonstrate that the API2-MALT1 fusion oncoprotein created by the recurrent t(11;18)(q21;q21) in mucosa-associated lymphoid tissue (MALT) lymphoma induces proteolytic cleavage of NF-kappaB-inducing kinase (NIK) at arginine 325. NIK cleavage requires the concerted actions of both fusion partners and generates a C-terminal NIK fragment that retains kinase activity and is resistant to proteasomal degradation. The resulting deregulated NIK activity is associated with constitutive noncanonical NF-kappaB signaling, enhanced B cell adhesion, and apoptosis resistance. Our study reveals the gain-of-function proteolytic activity of a fusion oncoprotein and highlights the importance of the noncanonical NF-kappaB pathway in B lymphoproliferative disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3124150/" 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/PMC3124150/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosebeck, Shaun -- Madden, Lisa -- Jin, Xiaohong -- Gu, Shufang -- Apel, Ingrid J -- Appert, Alex -- Hamoudi, Rifat A -- Noels, Heidi -- Sagaert, Xavier -- Van Loo, Peter -- Baens, Mathijs -- Du, Ming-Qing -- Lucas, Peter C -- McAllister-Lucas, Linda M -- R01 CA124540/CA/NCI NIH HHS/ -- R01 CA124540-04/CA/NCI NIH HHS/ -- R01 HL082914/HL/NHLBI NIH HHS/ -- R01CA124540/CA/NCI NIH HHS/ -- T32-HD07513/HD/NICHD NIH HHS/ -- T32-HL007622-21A2/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):468-72. doi: 10.1126/science.1198946.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics and Communicable Diseases, University of Michigan, 1150 West Medical Center Drive, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273489" target="_blank"〉PubMed〈/a〉

    Nectins establish a checkerboard-like cellular pattern in the auditory epithelium (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-30
    Description: In the auditory epithelium of the cochlea, the sensory hair cells and supporting cells are arranged in a checkerboard-like fashion, but the mechanism underlying this cellular patterning is unclear. We found that mouse hair cells and supporting cells express the immunoglobulin-like adhesion molecules nectin-1 and -3, respectively, and that their interaction mediates the heterotypic adhesion between these two cell types. Genetic removal of nectin-1 or -3 disrupted the checkerboard-like pattern, inducing aberrant attachment between hair cells. When cells expressing either nectin-1 or -3 were cocultured, they arranged themselves into a mosaic pattern. Thus, nectin-1 and -3 promote the formation of the checkerboard-like pattern of the auditory epithelia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Togashi, Hideru -- Kominami, Kanoko -- Waseda, Masazumi -- Komura, Hitomi -- Miyoshi, Jun -- Takeichi, Masatoshi -- Takai, Yoshimi -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1144-7. doi: 10.1126/science.1208467.

    Widespread RNA and DNA sequence differences in the human transcriptome (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-05-21
    Description: The transmission of information from DNA to RNA is a critical process. We compared RNA sequences from human B cells of 27 individuals to the corresponding DNA sequences from the same individuals and uncovered more than 10,000 exonic sites where the RNA sequences do not match that of the DNA. All 12 possible categories of discordances were observed. These differences were nonrandom as many sites were found in multiple individuals and in different cell types, including primary skin cells and brain tissues. Using mass spectrometry, we detected peptides that are translated from the discordant RNA sequences and thus do not correspond exactly to the DNA sequences. These widespread RNA-DNA differences in the human transcriptome provide a yet unexplored aspect of genome variation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3204392/" 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/PMC3204392/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Mingyao -- Wang, Isabel X -- Li, Yun -- Bruzel, Alan -- Richards, Allison L -- Toung, Jonathan M -- Cheung, Vivian G -- R01 HG005854/HG/NHGRI NIH HHS/ -- R01 HG005854-01/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jul 1;333(6038):53-8. doi: 10.1126/science.1207018.

    Selective inhibition of a regulatory subunit of protein phosphatase 1 restores proteostasis (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-03-10
    Description: Many biological processes are regulated through the selective dephosphorylation of proteins. Protein serine-threonine phosphatases are assembled from catalytic subunits bound to diverse regulatory subunits that provide substrate specificity and subcellular localization. We describe a small molecule, guanabenz, that bound to a regulatory subunit of protein phosphatase 1, PPP1R15A/GADD34, selectively disrupting the stress-induced dephosphorylation of the alpha subunit of translation initiation factor 2 (eIF2alpha). Without affecting the related PPP1R15B-phosphatase complex and constitutive protein synthesis, guanabenz prolonged eIF2alpha phosphorylation in human stressed cells, adjusting the protein production rates to levels manageable by available chaperones. This favored protein folding and thereby rescued cells from protein misfolding stress. Thus, regulatory subunits of phosphatases are drug targets, a property used here to restore proteostasis in stressed cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsaytler, Pavel -- Harding, Heather P -- Ron, David -- Bertolotti, Anne -- 084812/Wellcome Trust/United Kingdom -- MC_U105185860/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2011 Apr 1;332(6025):91-4. doi: 10.1126/science.1201396.

    K+ channel mutations in adrenal aldosterone-producing adenomas and hereditary hypertension (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-02-12
    Description: Endocrine tumors such as aldosterone-producing adrenal adenomas (APAs), a cause of severe hypertension, feature constitutive hormone production and unrestrained cell proliferation; the mechanisms linking these events are unknown. We identify two recurrent somatic mutations in and near the selectivity filter of the potassium (K(+)) channel KCNJ5 that are present in 8 of 22 human APAs studied. Both produce increased sodium (Na(+)) conductance and cell depolarization, which in adrenal glomerulosa cells produces calcium (Ca(2+)) entry, the signal for aldosterone production and cell proliferation. Similarly, we identify an inherited KCNJ5 mutation that produces increased Na(+) conductance in a Mendelian form of severe aldosteronism and massive bilateral adrenal hyperplasia. These findings explain pathogenesis in a subset of patients with severe hypertension and implicate loss of K(+) channel selectivity in constitutive cell proliferation and hormone production.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3371087/" 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/PMC3371087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, Murim -- Scholl, Ute I -- Yue, Peng -- Bjorklund, Peyman -- Zhao, Bixiao -- Nelson-Williams, Carol -- Ji, Weizhen -- Cho, Yoonsang -- Patel, Aniruddh -- Men, Clara J -- Lolis, Elias -- Wisgerhof, Max V -- Geller, David S -- Mane, Shrikant -- Hellman, Per -- Westin, Gunnar -- Akerstrom, Goran -- Wang, Wenhui -- Carling, Tobias -- Lifton, Richard P -- DK54983/DK/NIDDK NIH HHS/ -- K01 AR060300/AR/NIAMS NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Feb 11;331(6018):768-72. doi: 10.1126/science.1198785.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, CT 06510, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21311022" target="_blank"〉PubMed〈/a〉

By screening with fluorophore-assisted light inactivation in the developing mouse brain, we identified cartilage acidic protein-1B as a key molecule for lateral olfactory tract (LOT) formation and named it LOT usher substance (LOTUS). We further identified Nogo receptor-1 (NgR1) as a LOTUS-binding protein. NgR1 is a receptor of myelin-derived axon growth inhibitors, such as Nogo, which prevent neural regeneration in the adult. LOTUS suppressed Nogo-NgR1 binding and Nogo-induced growth cone collapse. A defasciculated LOT was present in lotus-deficient mice but not in mice lacking both lotus- and ngr1. These findings suggest that endogenous antagonism of NgR1 by LOTUS is crucial for normal LOT formation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3244695/" 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/PMC3244695/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sato, Yasufumi -- Iketani, Masumi -- Kurihara, Yuji -- Yamaguchi, Megumi -- Yamashita, Naoya -- Nakamura, Fumio -- Arie, Yuko -- Kawasaki, Takahiko -- Hirata, Tatsumi -- Abe, Takaya -- Kiyonari, Hiroshi -- Strittmatter, Stephen M -- Goshima, Yoshio -- Takei, Kohtaro -- R37 NS033020/NS/NINDS NIH HHS/ -- R37 NS033020-19/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2011 Aug 5;333(6043):769-73. doi: 10.1126/science.1204144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Pharmacology and Neurobiology, Yokohama City University Graduate School of Medicine, Yokohama 236-0004, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21817055" target="_blank"〉PubMed〈/a〉
