High-speed ultrasensitive instrumentation for myofibril mechanics measurements

, 1987
A novel instrument for measuring the mechanics of a single myofibril is described. The principle of the transducer operation is to attach a myofibril to a very fine wire suspended in a magnetic field.

Dapagliflozin alleviates high‐fat‐induced obesity cardiomyopathy by inhibiting ferroptosis

ESC Heart Failure, Volume 12, Issue 2, Page 1358-1373, April 2025.
Abstract Aim: Dapagliflozin (Dapa) is a novel hypoglycaemic agent with multiple cardiovascular protective effects, and it is widely used in treatment of heart failure patients, but whether it can improve obese phenotype of heart failure and its mechanism is still unclear.

The Effects of Angiotensin Receptor Neprilysin Inhibitor on Endoplasmic Reticulum Stress in Doxorubicin‐Mediated Cardiomyopathy‐Associated Heart Failure Model in Rats

Journal of Applied Toxicology, EarlyView.
ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Kinetic mechanism of myofibril ATPase

Biophysical Journal, 1994
The kinetic mechanism of myofibril ATPase was investigated using psoas and mixed back muscle over a range of ionic strengths. Myofibrils were labeled with pyrene iodoacetamide to measure the rate constants for the binding of ATP and formation of the weakly attached state.

Polyphenol dietary supplementation prevents inflammation‐induced muscle atrophy in a zebrafish (Danio rerio) model

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Diet‐induced inflammation is a major cause of muscle degeneration impacting human and animal health. Owing to their anti‐inflammatory and antioxidant properties, polyphenols have attracted considerable interest as feed additives.

Unconventional myosins muscle into myofibrils [PDF]

Journal of Biological Chemistry, 2019
"Myosin" is famous as a component of muscle fibrils, but the majority of myosin family members act elsewhere with roles unrelated to muscle contraction. The biological functions of a relatively new family of these unconventional myosins, myosins 18A and 18B, are poorly understood. New research from Horsthemke et al.

Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.

Zasp52’s differentially expressed intrinsically disordered region confers thin filament stability at the Z-disc

eLife
The Drosophila scaffolding protein Zasp52 is required to maintain structure at the muscle Z-disc, which experiences strong forces during contraction. It is alternatively spliced into many isoforms, some of which contain a long intrinsically disordered ...

Integration of scRNA‐Seq and scATAC‐Seq Revealed the Role of lncRNA RP11‐661C8.2 by Promoting EMT in Clear Cell Renal Cell Carcinoma

Molecular Carcinogenesis, EarlyView.
ABSTRACT Long noncoding RNAs (lncRNAs) play an important role in tumor progression. However, most of the previously discovered lncRNAs that promote or inhibit tumor progression were derived from bulk RNA‐seq results. Data from single‐cell RNA sequencing (scRNA‐seq) and single‐cell assay for transposase‐accessible chromatin using sequencing (scATAC‐seq)

Myofibril and mitochondria morphogenesis are coordinated by a mechanical feedback mechanism in muscle

, 2020
Complex animals build specialised muscle to match specific biomechanical and energetic needs. Hence, composition and architecture of sarcomeres as well as mitochondria are muscle type specific. However, mechanisms coordinating mitochondria with sarcomere
