Deciphering Anti‐Cancer Drug Efficacy Through Nanomechanical Vibrations in Living Gastric Cancer Organoids

Advanced Science, EarlyView.
This study developed an efficacy assessment platform that integrates patient‐derived gastric cancer organoids, atomic force microscopy (AFM)‐based nanomechanical vibration detection, deep learning analysis, and organoid mechanical modeling. It detects picomolar drug effects within 0.1 s signal, achieves 97% classification accuracy, and offers non ...

Cardiac myosin inhibitors in hypertrophic cardiomyopathy

Journal 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 ...

Human Fibroblast–Myeloid Cell Tissue Atlas Across the Lungs, Synovium, Skin, and Heart

Arthritis &Rheumatology, EarlyView.
Objective 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 ...

Cardiac Myosin-Binding Protein-C Phosphorylation and Cardiac Function [PDF]

Circulation Research, 2005
The role of cardiac myosin binding protein-C (cMyBP-C) phosphorylation in cardiac physiology or pathophysiology is unclear. To investigate the status of cMyBP-C phosphorylation in vivo, we determined its phosphorylation state in stressed and unstressed mouse hearts.

Cardiovascular Organoids With Adjustable Endothelial Composition via SOX17‐Engineered hPSCs

Biotechnology 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-binding protein C (MYBPC3) in cardiac pathophysiology [PDF]

Gene, 2015
More than 350 individual MYPBC3 mutations have been identified in patients with inherited hypertrophic cardiomyopathy (HCM), thus representing 40–50% of all HCM mutations, making it the most frequently mutated gene in HCM. HCM is considered a disease of the sarcomere and is characterized by left ventricular hypertrophy, myocyte disarray and diastolic ...

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

Cytoskeleton, 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.

Cardiac myosin binding protein C phosphorylation in cardiac disease [PDF]

Journal of Muscle Research and Cell Motility, 2011
Perturbations in sarcomeric function may in part underlie systolic and diastolic dysfunction of the failing heart. Sarcomeric dysfunction has been ascribed to changes in phosphorylation status of sarcomeric proteins caused by an altered balance between intracellular kinases and phosphatases during the development of cardiac disease.

Cytoskeleton–Membrane Uncoupling in Duchenne Muscular Dystrophy: Implications for Newborn Screening and Early Protection

Cytoskeleton, EarlyView.
ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.

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

Developmental 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 ...
