METTL21C mediates the occurrence of autophagy and formation of slow-twitch muscle fibers after exercise

, 2023
Abstract Homeostasis is essential for muscle repair and regeneration after skeletal muscle exercise. This study investigated the role of methyltransferase-like 21C (METTL21C) in skeletal muscle of mice after exercise and the potential mechanism.

Peroxisome proliferator-activated receptor-γ coactivator-1α in muscle links metabolism to inflammation [PDF]

, 2009
1. In higher eukaryotes, metabolism and immunity are tightly coupled. However, whereas evolutionary, a compromised immune response due to undernourishment has been the predominant problem, the inflammatory response to obesity and other life style ...

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

The Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Phosphoproteomic analysis identifies differentially expressed phosphorylation sites that affect muscle fiber type in pigs

Frontiers in Nutrition, 2022
Skeletal muscle of livestock is composed of both fast- and slow-twitch muscle fibers, which are key factors in their meat quality. However, the role of protein phosphorylation in muscle fiber type is not completely understood. Here, a fast-twitch (biceps

Function of mTOR complex 1 and 2 in skeletal muscle [PDF]

, 2009
Growth of an organ during development and during adaptation in the adult can be controlled by alterations either in the number or the size of cells. The two mechanisms are fundamentally different and require distinct regulation.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Anatomy of the Soft Palate and Its Role in Upper Airway Function: A Narrative Review

Clinical Anatomy, EarlyView.
ABSTRACT The soft palate is a complex anatomical structure, located at the posterior aspect of the oral and nasal cavities, able to dynamically create valve closure of the nasal and the oral cavities. Its precise movement is critical for speech, swallowing, and respiration. Despite its functional importance, detailed characterization of its constituent

LncRNA-TBP mediates TATA-binding protein recruitment to regulate myogenesis and induce slow-twitch myofibers

Cell Communication and Signaling, 2023
Background Skeletal muscle is comprised of heterogeneous myofibers that differ in their physiological and metabolic parameters. Of these, slow-twitch (type I; oxidative) myofibers have more myoglobin, more mitochondria, and higher activity of oxidative ...

Force generation and phosphate release steps in skinned rabbit soleus slow-twitch muscle fibers

Biophysical Journal, 1997
The force-generation and phosphate-release steps of the cross-bridge cycle in rabbit soleus slow-twitch muscle fibers (STF) were investigated using sinusoidal analysis, and the results were compared with those of rabbit psoas fast-twitch fibers (FTF). Single fiber preparations were activated at pCa 4.40 and ionic strength 180 mM at 20 degrees C.

Intraoperative Hemidiaphragm Stimulation Offsets Slow‐Twitch Muscle Fiber Atrophy and Contractile Dysfunction

The FASEB Journal, 2020
Prolonged mechanical ventilation induces considerable atrophy of slow‐ and fast‐twitch fibers in the human diaphragm. In pilot work, we detected early atrophy and specific force decrement in fast‐twitch fibers of patients following an average 4.6‐hour thoracic operations.
