Pulling Back to Move Forward
Animal cells can change shape and move by using actin polymerization to drive plasma membrane protrusion. Giannone and coworkers (this issue of Cell) describe how cells periodically pull back on these protrusions in order to sense and respond to the rigidity of their environment.
متن کاملProtein folding: Pulling back the frontiers
In the past few years, it has become possible to measure the forces required to mechanically unfold single protein molecules. Recently, the mechanical properties of heteropolyproteins have been studied, shedding new light on the mechanical design of modular proteins such as titin.
متن کاملPulling Back the Curtain: Improving Reviews in Environmental Health
The environment is increasingly being recognized as an important driver of human health and the weight of the evidence is sufficiently high, thus warranting timely preventative action (Diamanti-Kandarakis et al. 2009; President's Cancer Panel 2010; Woodruff et al. 2008). However, it is a challenge to keep abreast of the deluge of scientific literature linking the environment to health. The volu...
متن کاملOn vector bundles destabilized by Frobenius pull-back
Let X be a smooth projective curve of genus g > 1 over an algebraically closed field of positive characteristic. This paper is a study of a natural stratification, defined by the absolute Frobenius morphism of X, on the moduli space of vector bundles. In characteristic two, there is a complete classification of semi-stable bundles of rank 2 which are destabilized by Frobenius pull-back. We also...
متن کاملPolymer Motors: Pushing out the Front and Pulling up the Back
Mechanical work in cells is performed by specialized motor proteins that operate in a continuous mechanochemical cycle. Less complex, but still efficient, 'one-shot' motors evolved based on the assembly and disassembly of polymers. We review the mechanisms of pushing and pulling by actin and microtubule filaments and the organizational principles of actin networks. We show how these polymer for...
