Human Fibroblast‐Myeloid cell tissue atlas across lung, synovium, skin and heart

open access: yesArthritis &Rheumatology, Accepted Article.
Background The availability of single‐cell RNA sequencing (scRNAseq data) in different tissues and disease states provides an opportunity to compare cellular subsets and identify common and unique cellular activation. In this study, we aimed to characterize shared and tissue‐specific myeloid and stromal phenotypes and to uncover key cellular subtypes ...

Cardiovascular Organoids With Adjustable Endothelial Composition via SOX17‐Engineered hPSCs

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Organoids are considered a novel modeling platform for studying human biology and advancing health research. With the ability to demonstrate complex 3D structure and multicellular interactions, organoids have advanced studies in all major organs as a reliable model.

Cardiac myosin inhibitors in hypertrophic cardiomyopathy

open access: yesJournal of Cardiovascular Imaging
Abstract Mavacamten, the first selective and reversible cardiac myosin inhibitor (CMI), has been introduced to the clinical arena for the treatment of obstructive hypertrophic cardiomyopathy (HCM). By reducing excessive actin-myosin cross-bridging, this agent decreases myocardial contractility and alleviates the dynamic left ventricular ...

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 ...

Why are some muscles striated? A structural mechanism that amplifies shortening velocity

open access: yesAdvances in Physiology Education
Physiology textbooks consistently describe how the repeating sarcomeric organization of vertebrate skeletal and cardiac muscle generates a striated appearance.

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 ...

Inhibitory influence of phosphate and arsenate on contraction of skinned skeletal and cardiac muscle

open access: yes, 1990
It has been widely observed that Pi decreases maximum calcium-activated force (Fmax) and calcium sensitivity of skinned skeletal and cardiac muscle. However, whether a particular ionic species of Pi (i.e., H2PO4-) is responsible for these effects is ...

Heavy and light roles: myosin in the morphogenesis of the heart [PDF]

open access: yes, 2012
Myosin is an essential component of cardiac muscle, from the onset of cardiogenesis through to the adult heart. Although traditionally known for its role in energy transduction and force development, recent studies suggest that both myosin heavy-chain ...

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 ...
