Osmotic Tension Asymmetry Drives Electrotactic Migration via PDLIM7‐Polarized Microfilament Coordination in Breast Cancer Cells

open access: yesAdvanced Science, EarlyView.
This study establishes an electric field‐induced directional migration model using fluorescence tension probes to visualize microfilament forces and intracellular osmotic pressure dynamics in the electrotactic migration of breast cancer cells. This model delineates how electromechanical interactions among membrane potential, ion channels, OP, traction ...

Identification of an N-terminal glycogen synthase kinase 3 phosphorylation site which regulates the functional localisation of polycystin-2 in vivo and in vitro [PDF]

open access: yes, 2006
PKD2 is mutated in 15% of patients with autosomal dominant polycystic kidney disease (ADPKD). Polycystin-2 (PC2), the PKD2 protein, is a nonselective Ca2 + -permeable cation channel which may function at the cell surface and ER. Nevertheless, the factors

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

open access: yesAdvanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...

The COOH terminus of the c-Abl tyrosine kinase contains distinct F- and G-actin binding domains with bundling activity [PDF]

open access: yes, 1994
The myristoylated form of c-Abl protein, as well as the P210bcr/abl protein, have been shown by indirect immunofluorescence to associate with F-actin stress fibers in fibroblasts. Analysis of deletion mutants of c-Abl stably expressed in fibroblasts maps

Vitronectin at sites of cell-substrate contact in cultures of rat myotubes [PDF]

open access: yes, 1986
Affinity-purified antibodies to the serum glycoprotein, vitronectin, were used to study sites of cell-substrate contact in cultures of rat myotubes and fibroblasts.

Force stimulation promotes nerve regeneration by restoring cellular energy

open access: yesBMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Adenosine A1 receptors promote vasa vasorum endothelial cell barrier integrity via Gi and Akt-dependent actin cytoskeleton remodeling. [PDF]

open access: yesPLoS ONE, 2013
In a neonatal model of hypoxic pulmonary hypertension, a dramatic pulmonary artery adventitial thickening, accumulation of inflammatory cells in the adventitial compartment, and angiogenic expansion of the vasa vasorum microcirculatory network are ...

Interaction Between Actin and Microtubules During Plant Development

open access: yesCytoskeleton, EarlyView.
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Changing of expression actinbinding proteins in the kidney under dehydration

open access: yesВавиловский журнал генетики и селекции, 2018
Actin is related to main structural proteins in eukaryotes. In opposite to muscle alpha-actin, beta-actin is expressing in all types of cells. The constant reorganization of actin cytoskeleton takes place in non-muscle cells.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...
