Distinct profiles of mitochondrial bioenergetics and redox balance in left atrial and ventricular myocardium in the healthy rat heart

open access: yesExperimental Physiology, EarlyView.
Abstract The left ventricle (LV) is the primary pumping chamber of the heart, generating high systolic pressure to sustain systemic circulation. LV contractile dysfunction is a hallmark of various cardiovascular diseases and is associated with mitochondrial dysfunction, characterised by decreased oxidative phosphorylation (OXPHOS) capacity and ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe 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).

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Regulation of pyruvate dehydrogenase complex: Dancing to different drums in cancer

open access: yesInternational Journal of Cancer, Volume 158, Issue 6, Page 1464-1480, 15 March 2026.
Abstract Mechanisms governing the regulation of pyruvate dehydrogenase complex (PDC) are markedly modified in cancer cells compared to normal cells. PDC activity in normal cells is controlled by the reversible phosphorylation of three serine residues by dedicated kinases and phosphatases.

Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.

Novel Roles for the Ectoenzyme CD38 in the Maintenance of Transcriptional and Metabolic Homeostasis in Astrocytes

open access: yesGlia, Volume 74, Issue 2, February 2026.
CD38 deficiency influences brain NAD/NAM metabolism. Global CD38 deficiency drives changes in astrocyte mitochondrial, metabolic, senescence, and neurodegenerative‐related genes. CD38 deficiency alters glial reactivity and astrocyte bioenergetics. ABSTRACT CD38 is an ectoenzyme that converts NAD+ to NAM to help maintain bioenergetic homeostasis.

Lifespan‐Extending Endogenous Metabolites

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.
