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

open access: yesFEBS 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.

Requirements for contractility in disordered cytoskeletal bundles

open access: yes, 2012
Actomyosin contractility is essential for biological force generation, and is well understood in highly organized structures such as striated muscle. Additionally, actomyosin bundles devoid of this organization are known to contract both in vivo and in ...

Earthing effects on mitochondrial function: ATP production and ROS generation

open access: yesFEBS Open Bio, EarlyView.
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

The Association of Cortactin with Profilin-1 Is Critical for Smooth Muscle Contraction*

open access: yesJournal of Biological Chemistry, 2014
Background: Profilin-1 (Pfn-1) regulates actin dynamics and contraction in smooth muscle. Results: Contractile activation increases the association of cortactin with Pfn-1 via c-Abl, which controls actin dynamics and contraction. Conclusion: The coupling

Osmotic pressure‐induced calcium response states

open access: yesFEBS Open Bio, EarlyView.
Acute hypotonic stress triggers distinct calcium response patterns in HEK293T cells. These signals originate from the endoplasmic reticulum via RyR2 and propagate to neighboring cells through gap junctions. This result highlights a novel calcium‐dependent mechanism underlying the intracellular and intercellular response to osmotic pressure.

Supraspinal Fatigue Impedes Recovery From a Low-Intensity Sustained Contraction in Old Adults [PDF]

open access: yes, 2011
This study determined the contribution of supraspinal fatigue and contractile properties to the age difference in neuromuscular fatigue during and recovery from a low-intensity sustained contraction.

Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

open access: yesFEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

BCS1L‐Associated Disease: 5′‐UTR Variant Shifts the Phenotype Towards Axonal Neuropathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To investigate the consequences of a pathogenic missense variant (c.838C>T; p.L280F) and a 5′‐UTR regulatory variant (c.‐122G>T) in BCS1L on disease pathogenesis and to understand how regulatory variants influence disease severity and clinical presentation.

Calcium-independent contraction in lysed cell models of teleost retinal cones: activation by unregulated myosin light chain kinase or high magnesium and loss of cAMP inhibition. [PDF]

open access: yes, 1987
The retinal cones of teleost fish contract at dawn and elongate at dusk. We have previously reported that we can selectively induce detergent-lysed models of cones to undergo either reactivated contraction or reactivated elongation, with rates and ...
