Impairments in mitochondrial dynamics and morphology in skeletal muscle of breast cancer patients after a single paclitaxel administration

Experimental Physiology, EarlyView.
Abstract Standard chemotherapy regimens for patients with breast cancer are based on epirubicin–cyclophosphamide (EC) and paclitaxel (TAX) administrations. While it has been shown that first EC administration impairs mitochondrial homeostasis, the isolated effects of TAX have not been studied without previous chemotherapy exposure.

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 Fission Drives Human Glioblastoma Chemoresistance and Recurrence [PDF]

Glioblastoma (GBM) is both the most common and most lethal human brain tumour with a median life expectancy of 15-18 months despite combined surgery, temozolomide (TMZ) and whole-brain radiotherapy (WBR). GBM universally recurs after therapy owing to its

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).

Mitochondrial control of ciliary gene expression and structure in striatal neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.

NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.

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 ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
