Understanding and measuring mechanical signals in the tumor stroma

FEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

RNF213 and GUCY1A3 in Moyamoya Disease: Key Regulators of Metabolism, Inflammation, and Vascular Stability

Frontiers in Neurology, 2021
Moyamoya disease is an idiopathic chronically progressive cerebrovascular disease, which causes both ischemic and hemorrhagic stroke. Genetic studies identified RNF213/Mysterin and GUCY1A3 as disease-causing genes.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

FEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Research advances on the role of Runx2-related miRNAs in vascular calcification of chronic kidney disease

Linchuang shenzangbing zazhi, 2022
Vascular calcification （VC） is a major cause of cardiovascular mortality in patients with chronic kidney disease （CKD）. Current studies suggest that VC of CKD is not simply an ectopic deposition of calcium phosphate crystals in vascular wall.

Mechanosensitivity of the IInd kind: TGFb mechanism of cell sensing the substrate stiffness [PDF]

PLoS ONE 10:e0139959 (2015), 2015
Cells can sense forces applied to them, but also the stiffness of their environment. These are two different phenomena, and here we investigate the mechanosensitivity of the IInd kind: how the cell can measure an elastic modulus at a single point of adhesion -- and how the cell can receive and interpret the chemical signal released from the sensor.

Human vascular smooth muscle cells undergo vesicle-mediated calcification in response to changes in extracellular calcium and phosphate concentrations: a potential mechanism for accelerated vascular calcification in ESRD.

Journal of the American Society of Nephrology, 2004
Patients with ESRD have a high circulating calcium (Ca) x phosphate (P) product and develop extensive vascular calcification that may contribute to their high cardiovascular morbidity. However, the cellular mechanisms underlying vascular calcification in

Fibrinogen is chemotactic for vascular smooth muscle cells

FEBS Letters, 1989
We studied the effect of fibrinogen on the migration of bovine aortic smooth muscle cells in culture, using a Neuro Probe 48‐well micro chemotaxis chamber. Fibrinogen stimulated the migration of the cells dose‐dependently at concentrations from 30 to 1OOO μg/ml.

Quantification of alignment of vascular smooth muscle cells [PDF]

Cytometry Part A, 2018
AbstractVascular smooth muscle cells (VSMCs) are essential components that keep the tonus of the arterial network, which is the channel used to conduct the blood from the heart to the peripheral areas of the body. It is known that mechanical and architectural changes in VSMCs may lead to functional modifications in the cardiovascular system; therefore,

Occurrence, Risk Factors, and Prognosis of Acute Cerebral Microinfarcts in CADASIL

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic cerebral small vessel disease in adults. This study investigates the occurrence, risk factors, and prognosis of acute cerebral microinfarcts (ACMIs) in patients with CADASIL.

Dietary salt initiates redox signaling between endothelium and vascular smooth muscle through NADPH oxidase 4

Redox Biology, 2022
Prevention of phenotype switching of vascular smooth muscle cells is an important determinant of normal vascular physiology. Hydrogen peroxide (H2O2) promotes osteogenic differentiation of vascular smooth muscle cells through expression of Runt related ...
