Excessive training does not induce mitochondrial dysfunction or impair insulin signalling within skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Three weeks of overtraining in trained endurance athletes reduced exercise performance without impairing glucose tolerance. In skeletal muscle, overtraining was associated with increased expression of lipid metabolism‐related proteins, enhanced mitochondrial biogenesis and preserved insulin signalling, despite elevated oxidative ...

Molecular mechanisms of transhydrogenase activity and allosteric regulation in eukaryotic type II PHGDH Ser33

Nature Communications
L-serine is a critical structural constituent of proteins and membrane phospholipids, playing major roles in cell signaling, metabolism and development. L-Serine is synthesized through a conserved de novo pathway starting from the glycolytic intermediate

Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

The Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

Hexose-6-phosphate dehydrogenase modulates the effect of inhibitors and alternative substrates of 11[beta]-hydroxysteroid dehydrogenase 1 [PDF]

, 2008
Intracellular glucocorticoid reactivation is catalyzed by 11[beta]-hydroxysteroid dehydrogenase 1 (11[beta]-HSD1), which functions predominantly as a reductase in cells expressing hexose-6-phosphate dehydrogenase (H6PDH).

Transcriptomic and Metabolomic Profiling Identifies a Core Gene–Metabolite Axis Driving African Swine Fever Virus Replication in the Soft Tick Ornithodoros lahorensis

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Transcriptomic and metabolomic profiling of Ornithodoros lahorensis during African swine fever virus (ASFV) infection reveals that ASFV rewires host purine/pyrimidine metabolism, lipid metabolism, and energy metabolism. A core gene‐metabolite regulatory axis consisting of 12 key genes and 8 signature metabolites is identified to support viral genome ...

Cross‐tissue immune profiling of APOE ε4 reveals early dysregulation in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Apolipoprotein E (APOE) ε4 is the strongest genetic risk factor for late‐onset Alzheimer's disease (AD), but its contribution to disease pathogenesis remains incompletely understood. METHODS Here, we integrate proteomic profiling of plasma (n = 9028), cerebrospinal fluid (n = 1099), dorsolateral prefrontal cortex (n = 720), and ...

P7C3 Compounds as Targeted Mitochondrial Therapeutics for Brain Disorders

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
P7C3 activates NAMPT, the rate‐limiting enzyme in the NAD+ salvage pathway, elevating NAD+ levels in neurons. This engages SIRT1‐dependent nuclear signaling and SIRT3‐dependent mitochondrial regulation, enhancing mitochondrial quality control, reducing oxidative stress, and promoting neuronal survival.
