The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Murine obscurin and Obsl1 have functionally redundant roles in sarcolemmal integrity, sarcoplasmic reticulum organization, and muscle metabolism. [PDF]

, 2019
Biological roles of obscurin and its close homolog Obsl1 (obscurin-like 1) have been enigmatic. While obscurin is highly expressed in striated muscles, Obsl1 is found ubiquitously.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

The mitochondrial‐targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial‐apoptotic but not necroptotic signalling during ovarian cancer

The Journal of Physiology, EarlyView.
Abstract figure legend An evaluation of the degree to which mitochondrial hydrogen peroxide emission (mH2O2)‐mediated apoptotic and necroptotic signalling contributes to skeletal muscle atrophy in an orthotopic epithelial ovarian cancer (EOC) model. To determine whether attenuating mH2O2 could prevent regulated cell death signalling and mitigate muscle

A Clinical Study on the Utility of Muscle Biopsy in Patients with Suspected Myopathy

Annals of Indian Academy of Neurology
Background and Objectives: The role of muscle biopsy needs to be redefined in an era where genetic studies have largely supplanted the need for a pathological diagnosis. The objective of the study was to evaluate the utility of muscle biopsy in suspected

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Hypothyroid myopathy and its association with MICU1 gene mutations: a clinical caseauthors

Ожирение и метаболизм
Thyroid hormones are involved in the activation of glycogenolysis and mitochondrial oxidative phosphorylation. Kocher–Debré–Semelaigne Syndrome, also known as hypothyroid myopathy, is characterized by reduced glycogenolytic activity, leading to glycogen ...
