Nature Communications, 2016 Establishment and maintenance of apico-basal polarity in epithelial organs needs to be tightly coupled with cell division. Here the authors show that the Rab35 GTPase tethers intracellular vesicles containing key apical determinants at the cleavage site,

Mechanics of motility initiation and motility arrest in crawling cells
, 2015 Motility initiation in crawling cells requires transformation of a symmetric state into a polarized state. In contrast, motility arrest is associated with re-symmetrization of the internal configuration of a cell.

Quantification of cell edge velocities and traction forces reveals distinct motility modules during cell spreading. [PDF]
PLoS ONE, 2008 Actin-based cell motility and force generation are central to immune response, tissue development, and cancer metastasis, and understanding actin cytoskeleton regulation is a major goal of cell biologists.

Novel Cell Motility of Protozoa Living in the Hindgut of Termites
Journal of Trial and ErrorA symbiotic protozoan in the hindgut of termites was accidentally discovered. Its head and body continuously rotated in opposite directions without stopping or reversing directions. Rotations included the plasma membrane of each part of the cell, and the

Exopolysaccharide-independent social motility of Myxococcus xanthus. [PDF]
PLoS ONE, 2011 Social motility (S motility), the coordinated movement of large cell groups on agar surfaces, of Myxococcus xanthus requires type IV pili (TFP) and exopolysaccharides (EPS).

Coupling fission and exit of RAB6 vesicles at Golgi hotspots through kinesin-myosin interactions
Nature Communications, 2017 Actin and microtubules play important roles in Golgi structure and function but how they are connected is poorly understood. Here the authors show that KIF20A is involved in the fission process and, in association with Myosin II, serves to anchor RAB6 on

Neoplasia: An International Journal for Oncology Research, 2012 Taxanes are potent inhibitors of cell motility, a property implicated in their antiangiogenic and antimetastatic activity and unrelated to their antiproliferative effect. The molecular mechanism of this anti-motility activity is poorly understood.

Active Gel Model of Amoeboid Cell Motility
, 2013 We develop a model of amoeboid cell motility based on active gel theory. Modeling the motile apparatus of a eukaryotic cell as a confined layer of finite length of poroelastic active gel permeated by a solvent, we first show that, due to active stress ...

Modelling biological invasions: individual to population scales at interfaces [PDF]
, 2013 Extracting the population level behaviour of biological systems from that of the individual is critical in understanding dynamics across multiple scales and thus has been the subject of numerous investigations.
