Reply to Liu et al.: Loss of TGF-{beta} signaling in CARASIL pathogenesis [Biological Sciences]

07.04.2015 | Nathalie Beaufort; Eva Scharrer; Vanda Lux; Michael Ehrmann; Christof Haffner; Martin Dichgans, Proceedings of the National Academy of Sciences current issue, 2015

We thank Liu et al. (1) for their comments on our work on the link between the cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL)-related protease high temperature requirement protein A1 (HtrA1) and the TGF-β signaling pathway. To advance our ...

Loss of HtrA1-induced attenuation of TGF-{beta} signaling in fibroblasts might not be the main mechanism of CARASIL pathogenesis [Biological Sciences]

07.04.2015 | Ju Liu; Fengyun Dong; Josephine Hoh, Proceedings of the National Academy of Sciences current issue, 2015

In their contribution to PNAS, Beaufort et al. demonstrate that high temperature requirement protein A1 (HtrA1) facilitates TGF-β signaling through processing latent TGF-β binding protein 1 (LTBP-1) (1). Then the authors suggest the down-regulation of TGF-β signaling by lack of HtrA1-mediated ...

Allelic polymorphism of GIGANTEA is responsible for naturally occurring variation in circadian period in Brassica rapa [Plant Biology]

24.03.2015 | Qiguang Xie; Ping Lou; Victor Hermand; Rashid Aman; Hee Jin Park; Dae-Jin Yun; Woe Yeon Kim; Matti Juhani Salmela; B ..., Proceedings of the National Academy of Sciences current issue, 2015

GIGANTEA (GI) was originally identified by a late-flowering mutant in Arabidopsis, but subsequently has been shown to act in circadian period determination, light inhibition of hypocotyl elongation, and responses to multiple abiotic stresses, including tolerance to high salt and cold (freezing) ...

Dynamical evidence for causality between galactic cosmic rays and interannual variation in global temperature [Earth, Atmospheric, and Planetary Sciences]

17.03.2015 | Anastasios A. Tsonis; Ethan R. Deyle; Robert M. May; George Sugihara; Kyle Swanson; Joshua D. Verbeten; Geli Wang, Proceedings of the National Academy of Sciences current issue, 2015

As early as 1959, it was hypothesized that an indirect link between solar activity and climate could be mediated by mechanisms controlling the flux of galactic cosmic rays (CR) [Ney ER (1959) Nature 183:451–452]. Although the connection between CR and climate remains controversial, a significant ...

Century-scale trends and seasonality in pH and temperature for shallow zones of the Bering Sea [Environmental Sciences]

10.03.2015 | Jan Fietzke; Federica Ragazzola; Jochen Halfar; Heiner Dietze; Laura C. Foster; Thor Henrik Hansteen; Anton Eisenhau ..., Proceedings of the National Academy of Sciences current issue, 2015

No records exist to evaluate long-term pH dynamics in high-latitude oceans, which have the greatest probability of rapid acidification from anthropogenic CO2 emissions. We reconstructed both seasonal variability and anthropogenic change in seawater pH and temperature by using laser ablation ...

Warning signals for eruptive events in spreading fires [Physics]

24.02.2015 | Jerome M. Fox; George M. Whitesides, Proceedings of the National Academy of Sciences current issue, 2015

Spreading fires are noisy (and potentially chaotic) systems in which transitions in dynamics are notoriously difficult to predict. As flames move through spatially heterogeneous environments, sudden shifts in temperature, wind, or topography can generate combustion instabilities, or trigger ...

Suppression of phase separation and giant enhancement of superconducting transition temperature in FeSe1-xTex thin films [Applied Physical Sciences]

17.02.2015 | Yoshinori Imai; Yuichi Sawada; Fuyuki Nabeshima; Atsutaka Maeda, Proceedings of the National Academy of Sciences current issue, 2015

We demonstrate the successful fabrication on CaF2 substrates of FeSe1−xTex films with 0≤x≤1, including the region of 0.1≤x≤0.4, which is well known to be the “phase-separation region,” via pulsed laser deposition that is a thermodynamically nonequilibrium method. In the resulting films, we ...

Short time interval for condensation of high-temperature silicates in the solar accretion disk [Earth, Atmospheric, and Planetary Sciences]

03.02.2015 | Tu-Han Luu; Edward D. Young; Matthieu Gounelle; Marc Chaussidon, Proceedings of the National Academy of Sciences current issue, 2015

Chondritic meteorites are made of primitive components that record the first steps of formation of solids in our Solar System. Chondrules are the major component of chondrites, yet little is known about their formation mechanisms and history within the solar protoplanetary disk (SPD). We use the ...

Neuronal UCP1 expression suggests a mechanism for local thermogenesis during hibernation [Physiology]

03.02.2015 | Willem J. Laursen; Marco Mastrotto; Dominik Pesta; Owen H. Funk; Jena B. Goodman; Dana K. Merriman; Nicholas Ingolia ..., Proceedings of the National Academy of Sciences current issue, 2015

Hibernating mammals possess a unique ability to reduce their body temperature to ambient levels, which can be as low as −2.9 °C, by active down-regulation of metabolism. Despite such a depressed physiologic phenotype, hibernators still maintain activity in their nervous systems, as evidenced by ...

Giant reversible, facet-dependent, structural changes in a correlated-electron insulator induced by ionic liquid gating [Physics]

27.01.2015 | Jaewoo Jeong; Nagaphani B. Aetukuri; Donata Passarello; Steven D. Conradson; Mahesh G. Samant; Stuart S. P. Parkin, Proceedings of the National Academy of Sciences current issue, 2015

The use of electric fields to alter the conductivity of correlated electron oxides is a powerful tool to probe their fundamental nature as well as for the possibility of developing novel electronic devices. Vanadium dioxide (VO2) is an archetypical correlated electron system that displays a ...
