Vimentin is involved in regulation of mitochondrial motility and membrane potential by Rac1

Biology Open, 2015
In this study we show that binding of mitochondria to vimentin intermediate filaments (VIF) is regulated by GTPase Rac1. The activation of Rac1 leads to a redoubling of mitochondrial motility in murine fibroblasts.

Mechanism of ITGB2 in Osteoclast Differentiation in Osteoarthritis

Cell Proliferation, EarlyView.
In osteoclast precursors, higher ITGB1 than ITGB2 expression increases ITGA2‐ITGB1 integrin. In OA, extracellular signals upregulate ITGB2 and downregulate ITGB1, enhancing ITGA2‐ITGB2 integrin. This activates Rac1 to Rac‐GTP, driving osteoclast differentiation. Hyperactive subchondral osteoclasts accelerate OA progression.

The Small GTPase Rac1 Increases Cell Surface Stiffness and Enhances 3D Migration Into Extracellular Matrices

Scientific Reports, 2019
Membrane ruffling and lamellipodia formation promote the motility of adherent cells in two-dimensional motility assays by mechano-sensing of the microenvironment and initiation of focal adhesions towards their surroundings.

Pulmonary Vascular Endothelial Cells in Lung Diseases: Mechanisms, Therapeutic Strategies, and Future Directions

Cell Proliferation, EarlyView.
The pathogenic mechanisms of pulmonary vascular endothelial cells (VECs) in lung diseases and their multimodal therapeutic strategies. ABSTRACT Pulmonary vascular endothelial cells (VECs) are essential for the normal function of the lung, through maintaining vascular barrier integrity, regulating blood flow, and participating in inflammatory responses ...

Decoding the Role of Caveolin‐1 in Morphological Diversity and Self‐Renewal of Breast Cancer Cells

Cell Proliferation, EarlyView.
The silence of caveolin‐1 (Cav‐1) reproduced the morphological evolutionary behaviour of cancer cells, which is similar to the epithelial‐mesenchymal transition process. And Cav‐1 dependent morphological changes could affect cancer cell self‐renewal capacity through maintaining the morphological stability.

Epithelial cell shape changes contribute to regulation of ureteric bud branching morphogenesis

The FEBS Journal, EarlyView.
Ureteric bud (UB) branching determines the final size, shape, and nephron number of kidneys. Characterization of UB cell shapes identified dynamic round‐to‐elliptical transitions and cellular volume changes as critical epithelial modifications that increase morphological complexity in UB tips during their transitions through ampulla‐to‐asymmetric ...

Neocortical neurogenesis: a proneural gene perspective

The FEBS Journal, EarlyView.
The neocortex is a mammalian‐specific brain region responsible for higher‐order cognitive functioning that shares fundamental similarities across species, but which is larger and more complex in humans. Proneural genes, encoding basic helix–loop–helix transcription factors (TFs), are evolutionarily conserved drivers of neurogenesis from fly to human ...

Fear Conditioning Downregulates Rac1 Activity in the Basolateral Amygdala Astrocytes to Facilitate the Formation of Fear Memory

Frontiers in Molecular Neuroscience, 2017
Astrocytes are well known to scale synaptic structural and functional plasticity, while the role in learning and memory, such as conditioned fear memory, is poorly elucidated.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular
