    Description: Ricklefs and Renner (Reports, 27 January 2012, p. 464) found significant correlations for abundances and species diversities of families and orders of trees on different continents, which they suggested falsifies the neutral theory of biodiversity (NTB). We argue that the correlations among families and orders and the lack of correlations among genera can be explained by the NTB.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Anping -- Wang, Shaopeng -- Pacala, Stephen W -- New York, N.Y. -- Science. 2012 Jun 29;336(6089):1639; author reply 1639. doi: 10.1126/science.1222534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA. anpingc@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22745403" target="_blank"〉PubMed〈/a〉

    Description: The endoplasmic reticulum (ER) is the primary organelle for folding and maturation of secretory and transmembrane proteins. Inability to meet protein-folding demand leads to "ER stress," and activates IRE1alpha, an ER transmembrane kinase-endoribonuclease (RNase). IRE1alpha promotes adaptation through splicing Xbp1 mRNA or apoptosis through incompletely understood mechanisms. Here, we found that sustained IRE1alpha RNase activation caused rapid decay of select microRNAs (miRs -17, -34a, -96, and -125b) that normally repress translation of Caspase-2 mRNA, and thus sharply elevates protein levels of this initiator protease of the mitochondrial apoptotic pathway. In cell-free systems, recombinant IRE1alpha endonucleolytically cleaved microRNA precursors at sites distinct from DICER. Thus, IRE1alpha regulates translation of a proapoptotic protein through terminating microRNA biogenesis, and noncoding RNAs are part of the ER stress response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3742121/" 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/PMC3742121/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Upton, John-Paul -- Wang, Likun -- Han, Dan -- Wang, Eric S -- Huskey, Noelle E -- Lim, Lionel -- Truitt, Morgan -- McManus, Michael T -- Ruggero, Davide -- Goga, Andrei -- Papa, Feroz R -- Oakes, Scott A -- DK063720/DK/NIDDK NIH HHS/ -- DP2 OD001925/OD/NIH HHS/ -- DP2OD001925/OD/NIH HHS/ -- GM080783/GM/NIGMS NIH HHS/ -- P30 DK063720/DK/NIDDK NIH HHS/ -- R01 CA136577/CA/NCI NIH HHS/ -- R01 CA136717/CA/NCI NIH HHS/ -- R01 CA140456/CA/NCI NIH HHS/ -- R01 CA154916/CA/NCI NIH HHS/ -- R01 DK080955/DK/NIDDK NIH HHS/ -- R01 GM080783/GM/NIGMS NIH HHS/ -- R01CA136577/CA/NCI NIH HHS/ -- R01CA136717/CA/NCI NIH HHS/ -- R01CA140456/CA/NCI NIH HHS/ -- R01CA154916/CA/NCI NIH HHS/ -- R01DK080955/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):818-22. doi: 10.1126/science.1226191.
