The MYB36 transcription factor orchestrates Casparian strip formation [Plant Biology]

18.08.2015 | Takehiro Kamiya; Monica Borghi; Peng Wang; John M. C. Danku; Lothar Kalmbach; Prashant S. Hosmani; Sadaf Naseer; Tor ..., Proceedings of the National Academy of Sciences current issue, 2015

The endodermis in roots acts as a selectivity filter for nutrient and water transport essential for growth and development. This selectivity is enabled by the formation of lignin-based Casparian strips. Casparian strip formation is initiated by the localization of the Casparian strip domain ...

Sinuous flow in metals [Engineering]

11.08.2015 | Ho Yeung; Koushik Viswanathan; Walter Dale Compton; Srinivasan Chandrasekar, Proceedings of the National Academy of Sciences current issue, 2015

Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick “chip.” This anomaly has long been explained, based on ex situ observations, using a model of smooth plastic flow with uniform shear to describe material removal by chip formation. Here we show that ...

Mechanics of torque generation in the bacterial flagellar motor [Biophysics and Computational Biology]

11.08.2015 | Kranthi K. Mandadapu; Jasmine A. Nirody; Richard M. Berry; George Oster, Proceedings of the National Academy of Sciences current issue, 2015

The bacterial flagellar motor (BFM) is responsible for driving bacterial locomotion and chemotaxis, fundamental processes in pathogenesis and biofilm formation. In the BFM, torque is generated at the interface between transmembrane proteins (stators) and a rotor. It is well established that the ...

From intrinsically disordered protein to context-dependent folding: The {alpha}-synuclein tetramer is teased out of hiding [Biochemistry]

04.08.2015 | Thomas C. Pochapsky, Proceedings of the National Academy of Sciences current issue, 2015

An intriguing report by Dettmer et al. (1) in PNAS describes a link between the in vivo multimerization state of the neuronal protein α-synuclein (αSyn) and neurotoxicity. In this paper, it is demonstrated that αSyn mutations that abolish the formation of soluble αSyn tetramers in live neurons ...

Formation of surface nanodroplets under controlled flow conditions [Applied Physical Sciences]

28.07.2015 | Xuehua Zhang; Ziyang Lu; Huanshu Tan; Lei Bao; Yinghe He; Chao Sun; Detlef Lohse, Proceedings of the National Academy of Sciences current issue, 2015

Nanodroplets on a solid surface (i.e., surface nanodroplets) have practical implications for high-throughput chemical and biological analysis, lubrications, laboratory-on-chip devices, and near-field imaging techniques. Oil nanodroplets can be produced on a solid–liquid interface in a simple step ...

Dynamic epigenetic regulation of glioblastoma tumorigenicity through LSD1 modulation of MYC expression [Cell Biology]

28.07.2015 | David Kozono; Jie Li; Masayuki Nitta; Oltea Sampetrean; David Gonda; Deepa S. Kushwaha; Dmitry Merzon; Valya Ramakri ..., Proceedings of the National Academy of Sciences current issue, 2015

The available evidence suggests that the lethality of glioblastoma is driven by small subpopulations of cells that self-renew and exhibit tumorigenicity. It remains unclear whether tumorigenicity exists as a static property of a few cells or as a dynamically acquired property. We used ...

Myosin light chain phosphorylation to the rescue [Physiology]

28.07.2015 | Henk L. Granzier; Pieter P. de Tombe, Proceedings of the National Academy of Sciences current issue, 2015

A common cause of heart failure is hypertrophic cardiomyopathy (HCM) with a prevalence of at least 1 in 500 in adults (1); more recent data suggest that the prevalence of HCM may be as high as 1 in 200 (2). HCM is characterized by disorganized myocyte structure; formation of excess...

Mechanically patterning the embryonic airway epithelium [Biophysics and Computational Biology]

28.07.2015 | Victor D. Varner; Jason P. Gleghorn; Erin Miller; Derek C. Radisky; Celeste M. Nelson, Proceedings of the National Academy of Sciences current issue, 2015

Collections of cells must be patterned spatially during embryonic development to generate the intricate architectures of mature tissues. In several cases, including the formation of the branched airways of the lung, reciprocal signaling between an epithelium and its surrounding mesenchyme helps ...
