Zigzag turning preference of freely crawling cells. [PDF]

open access: yesPLoS ONE, 2011
The coordinated motion of a cell is fundamental to many important biological processes such as development, wound healing, and phagocytosis. For eukaryotic cells, such as amoebae or animal cells, the cell motility is based on crawling and involves a ...

Resistant Starches and Non-Communicable Disease: A Focus on Mediterranean Diet

open access: yesFoods, 2021
Resistant starch (RS) is the starch fraction that eludes digestion in the small intestine. RS is classified into five subtypes (RS1–RS5), some of which occur naturally in plant-derived foods, whereas the others may be produced by several processing ...

Soil Extracellular Enzymes from Brazilian Cerrado as Quality Bioindicators in Agricultural Areas in Goiás, Brazil

open access: yesFronteiras: Journal of Social, Technological and Environmental Science, 2016
The conversion of native Cerrado areas for the implementation of crops alters the physicochemical properties and biochemistry of soil. In this study we sought to understand the effect of seasonality and management used for planting sugarcane on the ...

Depletion of Ca2+ from the sarcoplasmic reticulum of cardiac muscle prompts phosphorylation of phospholamban to stimulate store refilling [PDF]

open access: yes, 1998
Nonmuscle cells have almost ubiquitously evolved a mechanism to detect and prevent Ca(2+) store depletionstore operated calcium entry. No such mechanism has, as yet, been reported in cardiac myocytes.

In Vitro Membrane Remodeling by ESCRT is Regulated by Negative Feedback from Membrane Tension

open access: yesiScience, 2019
Summary: Artificial cells can shed new light on the molecular basis for life and hold potential for new chemical technologies. Inspired by how nature dynamically regulates its membrane compartments, we aim to repurpose the endosomal sorting complex ...

Sphingosine 1-phosphate in renal diseases [PDF]

open access: yes, 2013
Because of its highly bioactive properties sphingosine 1-phosphate (S1P) is an attractive target for the treatment of several diseases. Since the expression of sphingosine kinases as well as S1P receptors was demonstrated in the kidney, questions about ...

Molecular dynamics as an approach to study prion protein misfolding and the effect of pathogenic mutations [PDF]

open access: yes, 2011
Computer simulation of protein dynamics offers unique high-resolution information that complements experiment. Using experimentally derived structures of the natively folded prion protein (PrP), physically realistic dynamics and conformational changes ...

Crawling and turning in a minimal reaction-diffusion cell motility model: Coupling cell shape and biochemistry

open access: yesPhysical Review E, 2017
We study a minimal model of a crawling eukaryotic cell with a chemical polarity controlled by a reaction-diffusion mechanism describing Rho GTPase dynamics. The size, shape, and speed of the cell emerge from the combination of the chemical polarity, which controls the locations where actin polymerization occurs, and the physical properties of the cell,

Aneuploidy and proteotoxic stress in cancer [PDF]

open access: yes, 2015
Although nearly ubiquitous in cancer, aneuploidy exerts detrimental effects on human cells. We recently demonstrated that aneuploid human cells exhibit impaired heat shock factor protein 1 (HSF1) and HSP90 function, suggesting a functional link between ...

Cool-associated Tyrosine-phosphorylated Protein 1 Is Required for the Anchorage-independent Growth of Cervical Carcinoma Cells by Binding Paxillin and Promoting AKT Activation. [PDF]

open access: yes, 2017
Cool-associated tyrosine-phosphorylated protein 1 (Cat-1) is a signaling scaffold as well as an ADP-ribosylation factor-GTPase-activating protein. Although best known for its role in cell migration, we recently showed that the ability of Cat-1 to bind ...
