Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Amyloid‐Forming Amylin Secreted by the Pancreas Promotes Hypoxia‐Inducible Factor Activation and Mitochondrial Alterations in Liver and Heart During Type 2 Diabetes Pathogenesis

Comprehensive Physiology, Volume 16, Issue 5, October 2026.
Human amylin is secreted from the pancreas of HIP rats and is amyloidogenic, forming aggregates systemically. In comparison with age‐matched control (WT), hyperglycemic (UCD) and amylin knockout rats (AKO), HIP rats showed increased hypoxia‐inducible factors (HIF‐1/2) in heart and liver, alongside alterations in mitochondrial electron transfer system ...

Aging of Skeletal Muscle: From Molecular Mechanisms to Therapeutic Interventions

MedComm, Volume 7, Issue 10, October 2026.
Skeletal muscle aging is driven by coordinated local breakdown across myofibers, stem and stromal cells, immune and vascular compartments, and neuromuscular control. These mechanisms promote mitochondrial dysfunction, inflammation, senescence, impaired regeneration, fibrosis, myosteatosis, denervation, and functional decline.

Mitochondrial Fusion and Fission in Age‐Related Cardio‐Cerebral Diseases: Mechanisms and Interventions

Aging Cell, Volume 25, Issue 10, October 2026.
Mitochondrial fission‐fusion imbalance contributes to age‐related cardio‐cerebral diseases like Alzheimer's disease, Parkinson's disease, Cerebral Infarction, Arteriosclerosis, Myocardial Infarction, Cardiac valve disease, Hypertension, and Cardiomyopathy. This review summarizes its regulatory mechanisms and interventions.

Repeated Moderate and Severe Heat Exposure Has Divergent Effects on Skeletal Muscle Mitochondrial, Proteostatic and Neuromuscular Outcomes in Mice

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Repeated heat exposure may promote adaptive remodeling or cumulative tissue burden depending on thermal dose, but its graded molecular and functional consequences during recovery remain unclear. We examined whether repeated moderate (39°C) and severe (41°C) whole‐body hyperthermia produce distinct skeletal muscle trajectories involving ...

Doxorubicin and 4‐Hydroperoxycyclophosphamide Alter Mitochondrial Dynamics and miR‐34 Expression in Spermatogonia and Spermatocytes In Vitro

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 4, October 2026.
ABSTRACT Doxorubicin (DOX) and cyclophosphamide (CP) are widely used chemotherapeutic agents with known gonadotoxic effects. Since miRNAs play a key role in the transcriptional regulation of spermatogenesis, they are suggested as biomarkers for male infertility.

Discovery-based proteomics using a novel Opa1-TurboID stable cell line reveals the metabolically dependent Opa1 protein interactome

Mitochondrial cristae, the cellular bioenergtic units of life, are dynamic subcompartments involved in respiratory efficiency, control of cytochrome c release and cellular proliferation. Optic Atrophy 1 (OPA1), a dynamin-related IMM protein, is a central

The loss of OPA1 accelerates intervertebral disc degeneration and osteoarthritis in aged mice

Nature Communications
Recent studies have highlighted the importance of mitochondria in NP cells and articular chondrocyte health. Since the understanding of mechanisms governing mitochondrial dynamics in these tissues is lacking, we investigated the role of OPA1, a ...

Defining metabolically dependent protein interactomes of Opa1 in cardiac mitochondria using a novel Opa1-TurboID mouse model

Mitochondrial cristae are dynamic structural compartments that contribute to respiratory efficiency. Optic Atrophy 1 (Opa1), a dynamin-related inner mitochondrial membrane (IMM) protein, is a central regulator of cristae shape that is retrieved in ...
