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.

Crosstalk between endoplasmic reticulum stress and mitochondrial homeostasis: A new perspective on ophthalmic disease treatment

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
The graphical abstract follows a top‐to‐bottom flow: stressors → ER–mitochondria crosstalk → ophthalmic diseases. The central panel highlights three core mitochondria‐associated membrane function axes, color‐coded as follows: light yellow for Ca2+ homeostasis, light blue for mitochondrial dynamics, and light red for mitophagy.

Loss of Mfn1 but not Mfn2 enhances adipogenesis.

PLoS ONE
ObjectiveA biallelic missense mutation in mitofusin 2 (MFN2) causes multiple symmetric lipomatosis and partial lipodystrophy, implicating disruption of mitochondrial fusion or interaction with other organelles in adipocyte differentiation, growth and/or ...

Heme Metabolism‐Derived Carbon Monoxide Regulates Skeletal Muscle Function

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Heme oxygenases, HO‐1 (Hmox1) and HO‐2 (Hmox2), regulate skeletal muscle homeostasis by degrading heme and generating carbon monoxide (CO), a bioactive signalling molecule. Although HO‐1 is known to influence muscle fibre composition and mitochondrial function, the role of HO‐2 in activity‐dependent neuromuscular plasticity remains ...

Structural insights of human mitofusin-2 into mitochondrial fusion and CMT2A onset

Nature Communications, 2019
Mitofusin-2 (MFN2) is a dynamin-like GTPase that plays a central role in regulating mitochondrial fusion and cell metabolism. Here, authors report crystal structures of truncated human MFN2 in different nucleotide-loading states and show that MFN2 forms ...

Mitochondrial reprogramming in lung cancer: a therapeutic vulnerability and a strategy for reversing drug resistance

The Journal of Pathology, Volume 269, Issue 2, Page 149-163, June 2026.
Abstract The conceptualization of mitochondria, previously restricted to their function as cellular ‘powerhouses’, has evolved to recognize their function as central coordinating hubs for the orchestration of cancer cell metabolism, signaling, and fate determination.

Mitochondrial Transplantation as a New Therapeutic Approach Against Cardiac and Renal Consequences in Male Rats With Myocardial Infarction

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim Myocardial infarction (MI) is one of the leading causes of death worldwide. MI is associated with cardiac structural and functional alterations. Among these, cardiac fibrosis may be significantly influenced by mitochondrial dysfunction. We sought to evaluate whether the injection of functional mitochondria from healthy muscle could improve

Mitochondrial fusion is required for spermatogonial differentiation and meiosis [PDF]

, 2019
Differentiating cells tailor their metabolism to fulfill their specialized functions. We examined whether mitochondrial fusion is important for metabolic tailoring during spermatogenesis.

OPA1 in MC4R Neurons Regulates Dietary Fat Intake and Body Weight in Mice

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Soybean oil intake induces OPA1 expression in hypothalamic MC4R neurons, contributing to adaptive regulation of appetite. MC4R neuron‐specific OPA1 deficiency increases soybean oil consumption and leads to obesity, with a more pronounced effect in females.
