Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families. [PDF]
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

The ordered extension of pseudopodia by amoeboid cells in the absence of external cues. [PDF]
Eukaryotic cells extend pseudopodia for movement. In the absence of external cues, cells move in random directions, but with a strong element of persistence that keeps them moving in the same direction Persistence allows cells to disperse over larger ...

Fluid Shear Attenuates Endothelial Pseudopodia Formation into the Capillary Lumen [PDF]
ABSTRACTObjective: Endothelial cells have the ability to undergo morphological shape changes, including projection of cytoplasmic pseudopodia into the capillary lumen. These cytoplasmic projections significantly influence the hemodynamic resistance to blood flow.

Food searching strategy of amoeboid cells by starvation induced run length extension. [PDF]
Food searching strategies of animals are key to their success in heterogeneous environments. The optimal search strategy may include specialized random walks such as Levy walks with heavy power-law tail distributions, or persistent walks with preferred ...

Cell polarity and cell migration both depend on pseudopodia and lamellipodia formation. These are regulated by coordinated signaling acting through G-protein coupled receptors and kinases such as PKB/AKT and SGK, as well as the actin cytoskeletal ...

AHNAK and inflammatory markers predict poor survival in laryngeal carcinoma. [PDF]
AHNAK/Desmoyokin is a giant protein which has been recently linked to reorganization of the actin cytoskeleton, cellular migration and invasion. Here, we investigated the role of AHNAK in the pathophysiology of larynx carcinoma-one of the major subtypes ...

Immature stages of some eastern Nearctic Tabanidae (Diptera). IX. Chrysops beameri Brennan and Hybomitra trispila (Wiedemann) [PDF]
The larvae and pupae of two species of Tabanidae (Diptera), Chrysops beameri Brennan and Hybomitra trispila (Wiedemann), are described and illustrated, and their similarities and differences relative to similar species are discussed.

A Supramolecular Nanoscavengers: Based "Cargo-Exchange" Breaking Cholesterol Metabolic Dysregulation for Glioblastoma Therapy. [PDF]
Dysregulated cholesterol metabolism, driven by a complex array of mechanisms, is a defining characteristic of glioblastoma (GBM). In this study, supramolecular nanoscavengers are engineered by harnessing the intrinsic binding affinity between endogenous small‐molecule cholesterol and β‐cyclodextrin (β‐CD).

Proteomic characterization of harvested pseudopodia with differential gel electrophoresis and specific antibodies [PDF]
Malignant gliomas (astrocytomas) are lethal tumors that invade the brain. Invasive cell migration is initiated by extension of pseudopodia into interstitial spaces. In this study, U87 glioma cells formed pseudopodia in vitro as cells pushed through 3 microm pores of polycarbonate membranes.

Reactive Oxygen Species as Signaling Molecules in Neutrophil Chemotaxis [PDF]
Neutrophil chemotaxis is a critical component in innate immunity. Recently, using a small-molecule functional screening, we identified NADPH-oxidase-dependent Reactive Oxygen Species (ROS) as key regulators of neutrophil chemotactic migration ...
