Noninvasive Estimation of Myosin Heavy Chain Composition in Human Skeletal Muscle [PDF]

, 2011
Purpose: Information on muscle fiber type composition is of great importance in muscle physiology and athletic performance. Because there are only a few techniques available that noninvasively and accurately provide an estimate of muscle fiber type ...

Effect of Skeletal Muscle and Fat Mass on Muscle Strength in the Elderly [PDF]

Healthcare, 2018
It is important for elderly people to maintain or improve muscle strength and for clinicians to know the factors that affect muscle strength. Therefore, the purpose of this study was to compare the effects of fat mass (FM) and skeletal muscle mass (SMM) on muscle strength. The participants included 192 community-dwelling elderly women.

Editorial: Emerging Mechanisms for Skeletal Muscle Mass Regulation [PDF]

Frontiers in Cell and Developmental Biology, 2021
Skeletal muscle is considered an essential tissue involved in many physiological functions such as metabolism, thermoregulation, respiration, and locomotion. It has become clear that genetic and environmental factors are intricately involved in regulating skeletal muscle volume or myofiber size.

Molecular brakes regulating mTORC1 activation in skeletal muscle following synergist ablation [PDF]

, 2014
The goal of the current work was to profile positive (mTORC1 activation, autocrine/paracrine growth factors) and negative [AMPK, unfolded protein response (UPR)] pathways that might regulate overload-induced mTORC1 activation with the hypothesis that a ...

Myostatin and the control of skeletal muscle mass

Current Opinion in Genetics & Development, 1999
The mechanisms by which tissue size is controlled are poorly understood. Over 30 years ago, Bullough proposed the existence of chalones, which act as tissue-specific negative growth regulators. The recent discovery of myostatin suggests that negative regulation of tissue growth may be an important mechanism for controlling skeletal muscle mass and ...

TAK1 preserves skeletal muscle mass and mitochondrial function through redox homeostasis

FASEB BioAdvances, 2020
Skeletal muscle atrophy is debilitating consequence of a large number of chronic disease states, aging, and disuse conditions. Skeletal muscle mass is regulated through coordinated activation of a number of signaling cascades.

Effects of alfacalcidol on circulating cytokines and growth factors in rat skeletal muscle [PDF]

, 2011
Supra-physiological levels of vitamin D induce skeletal muscle atrophy, which may be particularly detrimental in already sarcopaenic elderly. Neither the cause nor whether the atrophy is fibre type specific are known.

Obesity is associated with improved postoperative overall survival, independent of skeletal muscle mass in lung adenocarcinoma

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Although the obesity paradox is a topic of immense interest for oncologists and epidemiologists, the mechanism underlying this unexpected benefit of obesity is poorly understood.

Anthropometry of Muscle Mass: The Relationship Between Risk and Nutritional Status and Functionality in the Elderly

O Mundo da Saúde, 2023
Aging modifies the body composition and physiology of individuals, influencing the decrease in body mass and nutritional status. This study aims to analyze the association between anthropometric indicators of muscle mass assessment with nutritional risk ...

The AKT Pathway and Satellite Cell Activation in Skeletal Muscle Mass Regulation

Folia Medica Indonesiana, 2022
Highlight: • AKT or protein kinase B increase protein synthesis and control the degradation of proteins.  • Satellite cells was provided remarkable ability to regenerate skeletal muscle. • Stimulation of protein synthesis is effective therapy to maintain
