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

Mitochondrial dynamics proteins have other functions than just regulating mito dynamics, but they are often forgotten.

Congrats to the team and especially Rémi Chaney and @gillesgouspillou.bsky.social who did the heavy lifting on this review 💪

A 12‐Week Strength Training Improves Mitochondrial Respiration, H2O2 Emission and Skeletal Muscle Integrity in Women With Myotonic Dystrophy Type 1 Background Myotonic dystrophy type 1 (DM1) is caused by expanded CTG repeats in the DMPK gene, causing the accumulation of toxic RNA that sequesters RNA-binding proteins. Clinically, DM1 is characte.....

Our new very collaborative paper showing that muscle myosin has a reduced energy demand in diabetes. Big impact on weight control in our mind!!! Thank you to everyone involved and funders @lundbeckfonden.bsky.social @novo-nordisk.bsky.social @ucph.bsky.social @myoblue.bsky.social #diabetes

Our lab is excited to be a part of this enormous $23.8 million 'MitoRevolution' initiative led by Ana Andreazza, Scientific Director of Mito2i, and colleagues. We will be investigating the potential for mitochondrial transplantation in preclinical models of muscle disorders.

Volitional exercise elicits physiological and molecular improvements in the severe D2.mdx mouse model of Duchenne muscular dystrophy Abstract figure legend This study investigated the effects of volitional exercise on muscle health in the more severe D2.mdx model of Duchenne muscular dystrophy (DMD). We showed that 8–10 weeks of a...

Muscle fibroblasts and stem cells stimulate motor neurons in an age and exercise‐dependent manner Muscle biopsies were taken from males and females differing in age and exercise habits. Mononucleated cells were isolated and purified into muscle stem cells (MuSC) and muscle fibroblasts (FIB). Neur....

When studying mitochondria, it is essential to consider the impact of physical activity. Some findings attributed to 'aging' might actually be the result of decades of physical inactivity. ⬇️
