Insulin and insulin-like growth factor 1 receptors are required for normal expression of imprinted genes [Medical Sciences]

07-10-2014 | Jeremie Boucher; Marika Charalambous; Kim Zarse; Marcelo A. Mori; Andre Kleinridders; Michael Ristow; Anne C. Fergus ..., Proceedings of the National Academy of Sciences current issue, 2014

In addition to signaling through the classical tyrosine kinase pathway, recent studies indicate that insulin receptors (IRs) and insulin-like growth factor 1 (IGF1) receptors (IGF1Rs) can emit signals in the unoccupied state through some yet-to-be-defined noncanonical pathways. Here we show that ...

Atmospheric controls on northeast Pacific temperature variability and change, 1900-2012 [Earth, Atmospheric, and Planetary Sciences]

07-10-2014 | James A. Johnstone; Nathan J. Mantua, Proceedings of the National Academy of Sciences current issue, 2014

Over the last century, northeast Pacific coastal sea surface temperatures (SSTs) and land-based surface air temperatures (SATs) display multidecadal variations associated with the Pacific Decadal Oscillation, in addition to a warming trend of ∼0.5–1 °C. Using independent records of sea-level ...

One severe acute respiratory syndrome coronavirus protein complex integrates processive RNA polymerase and exonuclease activities [Microbiology]

16-09-2014 | Lorenzo Subissi; Clara C. Posthuma; Axelle Collet; Jessika C. Zevenhoven-Dobbe; Alexander E. Gorbalenya; Etienne Dec ..., Proceedings of the National Academy of Sciences current issue, 2014

In addition to members causing milder human infections, the Coronaviridae family includes potentially lethal zoonotic agents causing severe acute respiratory syndrome (SARS) and the recently emerged Middle East respiratory syndrome. The ∼30-kb positive-stranded RNA genome of coronaviruses encodes ...

Cyclin-dependent kinases regulate lysosomal degradation of hypoxia-inducible factor 1{alpha} to promote cell-cycle progression [Medical Sciences]

12-08-2014 | Maimon E. Hubbi; Daniele M. Gilkes; Hongxia Hu; Kshitiz; Ishrat Ahmed; Gregg L. Semenza, Proceedings of the National Academy of Sciences current issue, 2014

Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that mediates adaptive responses to oxygen deprivation. In addition, the HIF-1α subunit has a nontranscriptional role as a negative regulator of DNA replication through effects on minichromosome maintenance helicase loading and ...

Subpolar addition of new cell wall is directed by DivIVA in mycobacteria [Microbiology]

05-08-2014 | Xavier Meniche; Renee Otten; M. Sloan Siegrist; Christina E. Baer; Kenan C. Murphy; Carolyn R. Bertozzi; Christopher ..., Proceedings of the National Academy of Sciences current issue, 2014

Mycobacteria are surrounded by a complex multilayered envelope and elongate at the poles. The principles that organize the coordinated addition of chemically diverse cell wall layers during polar extension remain unclear. We show that enzymes mediating the terminal cytosolic steps of ...

Secondary bacterial flagellar system improves bacterial spreading by increasing the directional persistence of swimming [Environmental Sciences]

05-08-2014 | Sebastian Bubendorfer; Mihaly Koltai; Florian Rossmann; Victor Sourjik; Kai M. Thormann, Proceedings of the National Academy of Sciences current issue, 2014

As numerous bacterial species, Shewanella putrefaciens CN-32 possesses a complete secondary flagellar system. A significant subpopulation of CN-32 cells induces expression of the secondary system under planktonic conditions, resulting in formation of one, sometimes two, filaments at lateral ...

Money and trust among strangers [Economic Sciences]

10-09-2013 | Gabriele Camera; Marco Casari; Maria Bigoni, Proceedings of the National Academy of Sciences current issue, 2013

What makes money essential for the functioning of modern society? Through an experiment, we present evidence for the existence of a relevant behavioral dimension in addition to the standard theoretical arguments. Subjects faced repeated opportunities to help an anonymous counterpart who changed ...

R-spondin3 prevents mesenteric ischemia/reperfusion-induced tissue damage by tightening endothelium and preventing vascular leakage [Immunology]

27-08-2013 | Lakshmi Kannan; Katalin Kis-Toth; Kazuhisa Yoshiya; To-Ha Thai; Seema Sehrawat; Tanya N. Mayadas; Jurandir J. Dalle ..., Proceedings of the National Academy of Sciences current issue, 2013

Inflammation and vascular injury triggered by ischemia/reperfusion (I/R) represent a leading cause of morbidity and mortality in a number of clinical settings. Wnt and its homolog partners R-spondins, in addition to regulating embryonic development have recently been demonstrated to serve as ...

Brain-computer interfaces increase whole-brain signal to noise [Neuroscience]

13-08-2013 | T. Dorina Papageorgiou; Jonathan M. Lisinski; Monica A. McHenry; Jason P. White; Stephen M. LaConte, Proceedings of the National Academy of Sciences current issue, 2013

Brain–computer interfaces (BCIs) can convert mental states into signals to drive real-world devices, but it is not known if a given covert task is the same when performed with and without BCI-based control. Using a BCI likely involves additional cognitive processes, such as multitasking, ...

Identification of a small molecule with activity against drug-resistant and persistent tuberculosis [Microbiology]

02-07-2013 | Feng Wang; Dhinakaran Sambandan; Rajkumar Halder; Jianing Wang; Sarah M. Batt; Brian Weinrick; Insha Ahmad; Pengyu Y ..., Proceedings of the National Academy of Sciences current issue, 2013

A cell-based phenotypic screen for inhibitors of biofilm formation in mycobacteria identified the small molecule TCA1, which has bactericidal activity against both drug-susceptible and -resistant Mycobacterium tuberculosis (Mtb) and sterilizes Mtb in vitro combined with rifampicin or isoniazid. ...
