Mitochondrial alterations as potential early events in neuromuscular junction remodelling with muscle disuse

Experimental Physiology, EarlyView.
Abstract Physical inactivity impairs neuromuscular health, promoting skeletal muscle atrophy, mitochondrial changes, and neuromuscular junction (NMJ) instability. However, the interplay between mitochondria and NMJ alterations in the context of muscle disuse remains underexplored.

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.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Heterogeneous metabolic response of endothelial cells from different vascular beds to experimental hyperglycaemia and metformin

The Journal of Physiology, EarlyView.
Abstract figure legend Diabetes mellitus is associated with vascular pathology that leads to vascular complications in several tissues, such as retinopathy of the eye. Endothelial dysfunction plays a pivotal role in the progression of each complication.

The link between sarcopenic obesity and Alzheimer's disease: a brain‐derived neurotrophic factor point of view

The Journal of Physiology, EarlyView.
Abstract figure legend A, Sarcopenic obesity is defined as the age‐related loss of skeletal muscle mass and function that often leads to the progression of comorbidities, such as Alzheimer's disease (AD). Though the exact link between the two diseases is unknown, alterations in brain‐derived neurotrophic factor (BDNF) may be a contributor.

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

Role of Septin7 in mitochondrial dynamics and oxidative metabolism in C2C12 skeletal muscle cells

The Journal of Physiology, EarlyView.
Abstract figure legend Knockdown of Septin7 alters the expression of markers responsible for mitochondrial dynamics. Members of the electron transport chain are also affected by diminished Septin7 level resulting in functional changes of mitochondrial respiration. Abstract Mitochondria are dynamic organelles that undergo fusion and fission.

Müller Glial Kir4.1 Channel Dysfunction in APOE4‐KI Model of Alzheimer's Disease

Glia, Volume 74, Issue 3, March 2026.
APOE4 impairs Müller cell health by reducing Kir4.1 expression and buffering. APOE4 causes mitochondrial dysfunction with decreased ΔΨm and increased ROS. MitoQ restores Kir4.1 expression and reduces ROS in APOE4‐transfected cells. ABSTRACT Alzheimer's disease (AD), particularly late‐onset AD (LOAD), affects millions worldwide, with the apolipoprotein ...

Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.
