Muscle fiber atrophy

Rinsho Shinkeigaku, 2012
Muscle fibers have been classified into two major forms of red (slow twitch) and white (fast twitch) muscles. The red muscle utilizes lipid as energy source through mitochondrial metabolism and function to sustain the position against gravity (sometimes called as antigravity muscle). Under microgravity the red muscle is selectively involved.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

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.

Inhibiting 5‐lipoxygenase prevents skeletal muscle atrophy by targeting organogenesis signalling and insulin‐like growth factor‐1

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Skeletal muscle atrophy can occur in response to numerous factors, such as ageing and certain medications, and produces a major socio‐economic burden. At present, there are no approved drugs for treating skeletal muscle atrophy. Arachidonate 5‐

Heme oxygenase-1: A potential therapeutic target for improving skeletal muscle atrophy

Experimental Gerontology, 2023
Skeletal muscle atrophy is a common muscle disease that is directly caused by an imbalance in protein synthesis and degradation. At the histological level, it is mainly characterized by a reduction in muscle mass and fiber cross-sectional area (CSA ...

Loss of LCN2 Function Ameliorates Glucocorticoid-Induced Muscle Atrophy via Remodeling the Extracellular Matrix. [PDF]

Adv Sci (Weinh)
Glucocorticoids transcriptionally activate LCN2 expression via GR nuclear translocation. Secreted LCN2 binds MMP9 to degrade skeletal muscle ECM collagen, blocks integrin‐mediated mechanotransduction, bidirectionally disrupts muscle protein homeostasis, and reveals a novel target for steroid‐induced muscle atrophy.

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

Molecular Mechanisms of Muscle Atrophy [PDF]

Cell, 2004
Skeletal muscle atrophy has extreme adverse consequences. Molecular mechanisms that mediate the process of atrophy are not well defined. Recent studies have focused on diverse molecular cascades that control the activation of ubiquitin ligases, indicating that the involvement of the ubiquitin proteasome may be common to a range of atrophic stimuli.

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.
