The Health Benefits of Exercise: Molecular and Cellular Mechanisms

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Our synthesis integrates evidence on exercise‐induced regulatory mechanisms across multiple systems (musculoskeletal, cardiovascular, nervous, metabolic and immune), cross‐system, and aging. We also discusses adaptive regulation of exercise in extreme environments, along with the prospects and challenges of multiomics and AI‐driven precision exercise ...

Modulation of Cx46 hemichannels by nitric oxide

open access: yesAmerican Journal of Physiology-Cell Physiology, 2009
Gap-junction hemichannels are composed of six protein subunits (connexins). Undocked hemichannels contribute to physiological autocrine/paracrine cell signaling, including release of signaling molecules, cell-volume regulation, and glucose uptake.

The Multifaceted Role of Astrocyte Connexin 43 in Ischemic Stroke Through Forming Hemichannels and Gap Junctions

open access: yesFrontiers in Neurology, 2020
Ischemic stroke is a multi-factorial cerebrovascular disease with high worldwide morbidity and mortality. In the past few years, multiple studies have revealed the underlying mechanism of ischemia/reperfusion injury, including calcium overload, amino ...

Piezo1 Activation Rescues Anabolic Response to Mechanical Loading in Aged Bone via Connexin 43 Hemichannels

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Yoda1‐induced Piezo1 activation enhances Piezo1‐Cx43 interaction upon mechanical stimulation, triggering PI3K‐Akt signaling to drive Cx43 phosphorylation and hemichannel opening. These events elevate PGE2 release, suppress SOST expression in senescent osteocytes, and ultimately enhance bone anabolism on the endosteal surface.

Hemichannel blockers in an artificial bilayer environment.

open access: yes, 2012
(A) The addition of Heptanol to conducting Cx43 hemichannels terminated ionic current. (B) The addition of Carbenoxolone had no effect on open Cx43 hemichannels.

Astrocytes in Genetic Epilepsies: Supporting Actor or Key Player?

open access: yesJournal of Neuroscience Research, Volume 104, Issue 8, August 2026.
Astrocytes contribute to the pathophysiology of acquired epilepsy. However, less is known about their contribution to genetic epilepsy syndromes which often exhibit frequent comorbidity with neurodevelopmental and psychiatric disorders. Epileptic seizures are also frequently present in neurodevelopmental disorders.

Calcium Regulation of Connexin Hemichannels

open access: yesInternational Journal of Molecular Sciences
Connexin hemichannels (HCs) expressed at the plasma membrane of mammalian cells are of paramount importance for intercellular communication. In physiological conditions, HCs can form gap junction (GJ) channels, providing a direct diffusive path between neighbouring cells.

Nucleotide Metabolism in Health and Disease

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.

Inhibition of Connexin 43 Hemichannels Alleviates Cerebral Ischemia/Reperfusion Injury via the TLR4 Signaling Pathway

open access: yesFrontiers in Cellular Neuroscience, 2018
Connexin 43 (Cx43) widely exists in all components of the neurovascular unit (NVU) and is a constituent of gap junctions and hemichannels. In physiological states, gap junctions are open for regular intercellular communication, and the hemichannels ...

Interactive segmentation of membrane and membrane‐mimic densities in cryo‐EM maps

open access: yesActa Crystallographica Section D, Volume 82, Issue 8, Page 848-861, August 2026.
SURFER performs automated segmentation of contextual membrane and membrane‐mimic density in cryo‐EM maps to enable robust separation of macromolecular signal from surrounding detergent or lipid–membrane features. It is conveniently distributed as a plugin for UCSF ChimeraX, allowing interactive application within standard map‐visualization workflows ...
