Agrobacterium-delivered virulence protein VirE2 is trafficked inside host cells via a myosin XI-K-powered ER/actin network [Plant Biology]

14-Mar-2017 | Qinghua Yang; Xiaoyang Li; Haitao Tu; Shen Q. Pan, Proceedings of the National Academy of Sciences current issue, 2017

Agrobacterium tumefaciens causes crown gall tumors on various plants by delivering transferred DNA (T-DNA) and virulence proteins into host plant cells. Under laboratory conditions, the bacterium is widely used as a vector to genetically modify a wide range of organisms, including plants, yeasts, ...

Correction for Furuta et al., Measuring collective transport by defined numbers of processive and nonprocessive kinesin motors [Correction]

14-Mar-2017 | Proceedings of the National Academy of Sciences current issue, 2017

BIOPHYSICS AND COMPUTATIONAL BIOLOGY Correction for “Measuring collective transport by defined numbers of processive and nonprocessive kinesin motors,” by Ken’ya Furuta, Akane Furuta, Yoko Y. Toyoshima, Misako Amino, Kazuhiro Oiwa, and Hiroaki Kojima which appeared in issue 2, January 8, 2013, of ...

BET N-terminal bromodomain inhibition selectively blocks Th17 cell differentiation and ameliorates colitis in mice [Immunology and Inflammation]

14-Mar-2017 | Kalung Cheung; Geming Lu; Rajal Sharma; Adam Vincek; Ruihua Zhang; Alexander N. Plotnikov; Fan Zhang; Qiang Zhang; Y ..., Proceedings of the National Academy of Sciences current issue, 2017

T-helper 17 (Th17) cells have important functions in adaptor immunity and have also been implicated in inflammatory disorders. The bromodomain and extraterminal domain (BET) family proteins regulate gene transcription during lineage-specific differentiation of naïve CD4+ T cells to produce mature ...

Spatial confinement of active microtubule networks induces large-scale rotational cytoplasmic flow [Biophysics and Computational Biology]

14-Mar-2017 | Kazuya Suzuki; Makito Miyazaki; Jun Takagi; Takeshi Itabashi; Shin’ichi Ishiwata, Proceedings of the National Academy of Sciences current issue, 2017

Collective behaviors of motile units through hydrodynamic interactions induce directed fluid flow on a larger length scale than individual units. In cells, active cytoskeletal systems composed of polar filaments and molecular motors drive fluid flow, a process known as cytoplasmic streaming. The ...

Amino acid oxidation of the D1 and D2 proteins by oxygen radicals during photoinhibition of Photosystem II [Plant Biology]

14-Mar-2017 | Ravindra Kale; Annette E. Hebert; Laurie K. Frankel; Larry Sallans; Terry M. Bricker; Pavel Pospíšil, Proceedings of the National Academy of Sciences current issue, 2017

The Photosystem II reaction center is vulnerable to photoinhibition. The D1 and D2 proteins, lying at the core of the photosystem, are susceptible to oxidative modification by reactive oxygen species that are formed by the photosystem during illumination. Using spin probes and EPR spectroscopy, ...

Quantification of labile heme in live malaria parasites using a genetically encoded biosensor [Applied Biological Sciences]

14-Mar-2017 | James R. Abshire; Christopher J. Rowlands; Suresh M. Ganesan; Peter T. C. So; Jacquin C. Niles, Proceedings of the National Academy of Sciences current issue, 2017

Heme is ubiquitous, yet relatively little is known about the maintenance of labile pools of this cofactor, which likely ensures its timely bioavailability for proper cellular function. Quantitative analysis of labile heme is of fundamental importance to understanding how nature preserves access ...

Shrinking instability of toroidal droplets [Physics]

14-Mar-2017 | Alexandros A. Fragkopoulos; Ekapop Pairam; Eric Berger; Phil N. Segre; Alberto Fernández-Nieves, Proceedings of the National Academy of Sciences current issue, 2017

Toroidal droplets are inherently unstable due to surface tension. They can break up, similar to cylindrical jets, but also exhibit a shrinking instability, which is inherent to the toroidal shape. We investigate the evolution of shrinking toroidal droplets using particle image velocimetry. We ...

Synaptic vesicle glycoprotein 2C (SV2C) modulates dopamine release and is disrupted in Parkinson disease [Pharmacology]

14-Mar-2017 | Amy R. Dunn; Kristen A. Stout; Minagi Ozawa; Kelly M. Lohr; Carlie A. Hoffman; Alison I. Bernstein; Yingjie Li; Minz ..., Proceedings of the National Academy of Sciences current issue, 2017

Members of the synaptic vesicle glycoprotein 2 (SV2) family of proteins are involved in synaptic function throughout the brain. The ubiquitously expressed SV2A has been widely implicated in epilepsy, although SV2C with its restricted basal ganglia distribution is poorly characterized. SV2C is ...

Vitamin D receptor regulates autophagy in the normal mammary gland and in luminal breast cancer cells [Cell Biology]

14-Mar-2017 | Luz E. Tavera-Mendoza; Thomas Westerling; Eric Libby; Andriy Marusyk; Laura Cato; Raymundo Cassani; Lisa A. Cameron; ..., Proceedings of the National Academy of Sciences current issue, 2017

Women in North America have a one in eight lifetime risk of developing breast cancer (BC), and a significant proportion of these individuals will develop recurrent BC and will eventually succumb to the disease. Metastatic, therapy-resistant BC cells are refractory to cell death induced by ...

Ligand binding to telomeric G-quadruplex DNA investigated by funnel-metadynamics simulations [Biophysics and Computational Biology]

14-Mar-2017 | Federica Moraca; Jussara Amato; Francesco Ortuso; Anna Artese; Bruno Pagano; Ettore Novellino; Stefano Alcaro; Miche ..., Proceedings of the National Academy of Sciences current issue, 2017

G-quadruplexes (G4s) are higher-order DNA structures typically present at promoter regions of genes and telomeres. Here, the G4 formation decreases the replicative DNA at each cell cycle, finally leading to apoptosis. The ability to control this mitotic clock, particularly in cancer cells, is ...
