Article Abstract

Skeletal muscle is one of the largest tissues in human body. Besides enabling voluntary movements and maintaining body's metabolic homeostasis, skeletal muscle is also a target of many pathological conditions. Mitochondria occupy 10-15% volume of a muscle myofiber and regulate many cellular processes, which often determine the fate of the cell. Isolation of mitochondria from skeletal muscle provides opportunities for various multi-omics studies with a focus on mitochondria in biomedical research field. Here we describe a protocol to efficiently isolate mitochondria with high quality and purity from skeletal muscle of mice using Nycodenz density gradient ultracentrifugation.

Skeletal Muscle Alpha Actin (ACTA1) Acetylation Enhances Myosin Binding and Increases Calcium Sensitivity.

Skeletal muscle alpha actin (ACTA1) is important for muscle contraction and relaxation, with historical studies focused on ACTA1 mutations in muscle dysfunction. Proteomics reports have consistently observed that actin, including ACTA1, is acetylated at multiple lysine sites. However, few reports have studied the effects of actin acetylation on cellular function, and fewer have examined ACTA1 acetylation on skeletal muscle function.

Integrative physiology of skeletal muscle for maintaining cognitive health.

Cognitive decline and physical impairment are often linked with ageing, contributing to declines in health span and loss of independence in older adults. Pathological cognitive decline with age is largely considered to be a brain-centric challenge. However, recent findings have begun to challenge this paradigm as the health of peripheral systems, namely skeletal muscle, predict cognitive decline associated with Alzheimer's disease (AD).

Background: Excessive oxidative stress is well known to participate in the pathogenesis of hypertension. A major regulator of oxidative stress is the transcription factor Nuclear factor erythroid 2-related factor 2 (Nrf2). However, the role of Nrf2 in the pathogenesis of hypertension is not completely understood, especially at the endothelial cell level.
