Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

The Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

The Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.

Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Focused Ultrasound‐Induced Mechanical Ablation Affects the Carbohydrate Metabolism of Residual/Peri‐Focally Localized Glioblastoma Cells

International Journal of Cancer, Volume 159, Issue 4, Page 1005-1016, 15 August 2026.
Glioblastoma (GBM) is highly aggressive and therapy‐resistant, warranting exploration of novel treatment strategies, among them mechanical high‐intensity focused ultrasound (mFUS), which holds significant promise for tumor ablation. The present study examined mFUS‐induced changes specifically in carbohydrate metabolism, which affects vulnerability to ...

Stage‐Specific Metabolic and Proteomic Dynamics Underlying Ripening and Quality Formation in Tropical Evergreen Pomegranate

eFood, Volume 7, Issue 4, August 2026.
Integrated multi‐omics reveals that pomegranate ripening between 90 and 130 days drives optimal sugar‐acid balance and pigmentation via coordinated regulation of phenylpropanoid, flavonoid, and carbohydrate metabolism pathways. ABSTRACT Pomegranate fruit development involves coordinated physiological, metabolic, and proteomic changes shaping coloration

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 826-838, August 2026.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

Metformin Partially Attenuates Simvastatin‐Induced Myotoxic Responses in C2C12 Myotubes Through Metabolic Adaptation

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Simvastatin induces metabolic suppression, mitochondrial dysfunction, and atrophy‐related responses in skeletal muscle cells. In differentiated C2C12 myotubes, metformin partially attenuates these alterations by preserving myotube structural integrity, reducing cellular stress signaling, and maintaining mitochondrial network organization despite ...
