Genetically Encoded Biosensors Reveal PKA Hyperphosphorylation on the Myofilaments in Rabbit Heart Failure [PDF]

open access: yes, 2016
RATIONALE: In heart failure, myofilament proteins display abnormal phosphorylation, which contributes to contractile dysfunction. The mechanisms underlying the dysregulation of protein phosphorylation on myofilaments is not clear.

A comprehensive proteome and phosphoproteome atlas across nine organs of the Chinese hamster

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study presents the first comprehensive proteome and phosphoproteome atlas of the Chinese hamster across nine organs (heart, liver, lung, kidney, spleen, cerebral cortex, skeletal muscle, stomach, and testis or ovary). A total of 14 219 proteins were identified in the proteome, with 11 828 phosphorylated proteins and 47 122 phosphorylation sites ...

A permeabilized cell model for studying cell division: a comparison of anaphase chromosome movement and cleavage furrow constriction in lysed PtK1 cells. [PDF]

open access: yes, 1981
After lysis in a Brij 58-polyethylene glycol medium, PtK1 cells are permeable to small molecules, such as erythrosin B, and to proteins, such as rhodamine-labeled FAB, myosin subfragment-1, and tubulin.

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 ...

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Mavacamten Cardiac Myosin Inhibitor: Clinical Applications and Future Perspectives

open access: yesCureus
Mavacamten is a first-in-class, selective allosteric inhibitor of cardiac myosin adenosine triphosphatase (ATPase) that has emerged as a novel therapeutic option for patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) who remain refractory to conventional therapy, such as beta-blockers and calcium channel blockers.

Isoform Specificity of a Compound Targeting Actin Filaments Containing Tropomyosin Tpm1.8/1.9

open access: yesCytoskeleton, EarlyView.
ABSTRACT The unbranched actin filaments in mammalian cells are usually composed of co‐polymers of a specific tropomyosin isoform with actin. Genetic manipulation has revealed that the tropomyosins largely define the functional properties of actin filaments in an isoform‐specific, non‐redundant manner.

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Micro-RNA family that modulates fibrosis and uses thereof [PDF]

open access: yes, 2017
The present invention relates to the identification of a microRNA family, designated miR-29a-c, that is a key regulator of fibrosis in cardiac tissue. The inventors show that members of the miR-29 family are down-regulated in the heart tissue in response

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...
