Heat treatment combined with hybrid exercises retraining mitigates cellular markers of protein turnover after hindlimb suspension in male mice: A pilot study

Experimental Physiology, EarlyView.
Abstract Recent evidence suggests that heat treatment (HT) and resistance training can limit skeletal muscle mass loss during immobilization. However, the effects of repeated HT sessions combined with hybrid exercises (EX), which promote both endurance and resistance responses, on muscle protein turnover following hindlimb unloading (HU) remain ...

Drp1–associated genes implicated in sepsis survival

Frontiers in Immunology
Sepsis is a severe and life-threatening medical syndrome that can lead to organ failure and death. Despite advances in medical treatment, current therapies are often inadequate, with high septic mortality rates. Therefore, there is a critical need for reliable prognostic markers to be used in clinical settings to improve the management and outcomes of ...

Mitochondrial capacities and quality control following short‐ and long‐term weight restoration after simulated anorexia nervosa

Experimental Physiology, EarlyView.
Abstract Anorexia nervosa (AN) is a psychiatric disorder characterized by prolonged caloric restriction and skeletal muscle atrophy. Mitochondrial health is a key mediator of muscle function, yet the role of mitochondria during AN and following weight regain has not been investigated. The objective of this study was to evaluate mitochondrial capacities

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.

Impact of Drp1 Loss on Organelle Interaction, Metabolism, and Inflammation in Mouse Liver

Cells
Dynamin-related protein 1 (Drp1) is a crucial player in mitochondrial fission and liver function. The interactions between mitochondria, endoplasmic reticulum (ER), and lipid droplets (LDs) are fundamental for lipid metabolism.

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).

Nanobodies as novel tools to monitor the mitochondrial fission factor Drp1

Life Science Alliance
This study reports the first nanobodies against the mitochondrial fission protein Drp1 for application in proteomics, high-resolution microscopy and live cell imaging. In cells, mitochondria undergo constant fusion and fission.
