The Evolutionarily Conserved TPM1 Super‐Enhancer Drives Skeletal Muscle Regeneration via Mechanotransduction Signaling

open access: yesAdvanced Science, EarlyView.
By integrating biomechanical and epigenetic cues, the evolutionarily conserved TPM1 super‐enhancer drives myogenesis via TEAD4‐mediated chromatin looping. This mechanism produces species‐specific outputs (linear TPM1 mRNA in mice and CircTPM1 in bovine) that activate PI3K/AKT mechanotransduction and the MYH10/MYL3 axis to execute cytoskeletal ...

Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

open access: yesAdvanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Overexpression of Lifeact in the C. elegans body wall muscle causes sarcomere disorganization and embryonic or larval lethality

open access: yesFrontiers in Cell and Developmental Biology
Lifeact is a short peptide that is widely utilized as a probe for actin filaments in live imaging. However, high concentrations of Lifeact can alter actin filament dynamics and cause artificial modifications to the actin cytoskeleton.

Considerations for an In Vitro, Cell-Based Testing Platform for Detection of Drug-Induced Inotropic Effects in Early Drug Development. Part 2: Designing and Fabricating Microsystems for Assaying Cardiac Contractility With Physiological Relevance Using Human iPSC-Cardiomyocytes

open access: yesFrontiers in Pharmacology, 2019
Contractility of the myocardium engines the pumping function of the heart and is enabled by the collective contractile activity of its muscle cells: cardiomyocytes.

F‐Box and Leucine‐Rich Repeat Protein 4 (FBXL4) Maintains Sarcomere Integrity and Cardiac Function by Enhancing K48‐Linked Ubiquitinated Degradation of Profilin‐1 (PFN1)

open access: yesAdvanced Science, EarlyView.
Schematic diagram depicting the proposed signaling mechanisms underlying the effects of FBXL4 in the setting of cardiac hypertrophy. Under hypertrophic stimulation, cardiomyocytes‐specific overexpression FBXL4 maintains sarcomere integrity and cardiac function by enhancing K48‐linked ubiquitinated degradation of PFN1 at the K70 site.

Are the class 18 myosins Myo18A and Myo18B specialist sarcomeric proteins?

open access: yesFrontiers in Physiology
Initially, the two members of class 18 myosins, Myo18A and Myo18B, appeared to exhibit highly divergent functions, complicating the assignment of class-specific functions.

Single sarcomere contraction dynamics in a whole muscle

open access: yesScientific Reports, 2018
The instantaneous sarcomere length (SL) is regarded as an important indicator of the functional properties of striated muscle. Previously, we found greater sarcomere elongations at the distal end compared to the mid-portion in the mouse tibialis anterior

Incidence and Prevalence of Congenital Myopathies ‐ A Population‐Based Study From Western Sweden

open access: yesAnnals of Neurology, EarlyView.
Objective Congenital myopathies are a group of rare genetic muscle disorders. Previous studies have estimated point prevalences which only include surviving individuals. Our aim was to perform an epidemiological study with strict inclusion criteria, using modern diagnostic technology to present both incidences and prevalences, and to describe the ...
