Interaction of rat liver lysosomal membranes with actin. [PDF]

open access: yes, 1984
Membranes were prepared from lysosomes purified 80-fold by centrifugation in a discontinuous metrizamide gradient. When salt-washed membranes were combined with rabbit muscle actin, an increase in viscosity could be measured using a falling ball ...

Atomic Force Microscopy of height fluctuations of fibroblast cells [PDF]

open access: yes, 2002
We investigated the nanometer scale height fluctuations of 3T3 fibroblast cells with the atomic force microscope (AFM) under physiological conditions. Correlation between these fluctuations and lateral cellular motility can be observed.

Engineered EVs‐Mediated miR‐222 Targeting PTEN/FN1 Axis Reverses Anthracycline Resistance in HER2‐Negative Breast Cancer

open access: yesCancer Science, EarlyView.
We revealed the pivotal role of EVs‐mediated miR‐222 inhibition in modulating adriamycin resistance through post‐transcriptional regulation. Through the systematic implementation of Engineered EVs containing targeted miRNA mimics and inhibitors, we successfully delineated the specific contribution of EVs‐derived miR‐222 to drug resistance phenotypes in

Constitutive-law Modeling of Microfilaments from their Discrete-Structure Simulations - A Method based on an Inverse Approach Applied to a Static Rod Model [PDF]

open access: yesarXiv, 2010
Twisting and bending deformations are crucial to the biological functions of microfilaments such as DNA molecules. Although continuum-rod models have emerged as efficient tools to describe the nonlinear dynamics of these deformations, a major roadblock in the continuum-mechanics-based description of microfilaments is the accurate modeling of the ...

Mechanotransduction Mediated by PDLIM5: The Critical Role of Serpin E2/Integrin β3‐Cytoskeleton‐Nucleoskeleton Axis in Mechanical Osteogenic Programming

open access: yesCell Proliferation, EarlyView.
Large segmental bone defects can result in non‐union of fractures and present a formidable challenge in clinical management. This study aims to investigate the role of mechanical stimulation in regulating osteogenic differentiation of stem cells via the mechanosensitive protein PDLIM5, thereby promoting bone regeneration and repair.

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

Spotting plants’ microfilament morphologies and nanostructures [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Significance Microfibers existing in the tracheary systems of plants are crucial for the plants to survive. These microfilaments are curled up, forming left-handed helices that make the contour of tubes responsible for the transport of water and nutrients from the roots to the leaves. The microfilaments present mechanical properties that vary
