Connexin 43 in Mitochondria: What Do We Really Know About Its Function?

open access: yesFrontiers in Physiology, 2022
Connexins are known for their ability to mediate cell-cell communication via gap junctions and also form hemichannels that pass ions and molecules over the plasma membrane when open.

Single and fractionated ionizing radiation induce alterations in endothelial connexin expression and channel function [PDF]

open access: yes, 2019
Radiotherapy is an effective treatment for most tumor types. However, emerging evidence indicates an increased risk for atherosclerosis after ionizing radiation exposure, initiated by endothelial cell dysfunction. Interestingly, endothelial cells express

Structure and permeability of ion-channels by integrated AFM and waveguide TIRF microscopy. [PDF]

open access: yes, 2014
Membrane ion channels regulate key cellular functions and their activity is dependent on their 3D structure. Atomic force microscopy (AFM) images 3D structure of membrane channels placed on a solid substrate.

Gap Junction-Dependent and -Independent Functions of Connexin43 in Biology

open access: yesBiology, 2022
For the first time in animal evolution, the emergence of gap junctions allowed direct exchanges of cellular substances for communication between two cells.

Mechanisms Underlying Connexin Hemichannel Activation in Disease [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Gap junctions and connexin hemichannels mediate intercellular and extracellular communication, respectively. While gap junctions are seen as the “good guys” by controlling homeostasis, connexin hemichannels are considered as the “bad guys”, as their activation is associated with the onset and dissemination of disease.

Gap Junctions and Hemichannels Composed of Connexins and Pannexins Mediate the Secondary Brain Injury Following Intracerebral Hemorrhage

open access: yesBiology, 2021
Intracerebral hemorrhage (ICH) is a devastating disease with high mortality and morbidity; the mortality rate ranges from 40% at 1 month to 54% at 1 year; only 12–39% achieve good outcomes and functional independence.

Connexin 43 Hemichannel Activity Promoted by Pro-Inflammatory Cytokines and High Glucose Alters Endothelial Cell Function

open access: yesFrontiers in Immunology, 2018
The present work was done to elucidate whether hemichannels of a cell line derived from endothelial cells are affected by pro-inflammatory conditions (high glucose and IL-1β/TNF-α) known to lead to vascular dysfunction.

Cx43-hemichannel function and regulation in physiology and pathophysiology: insights from the bovine corneal endothelial cell system and beyond [PDF]

open access: yes, 2014
Intercellular communication in primary bovine corneal endothelial cells (BCECs) is mainly driven by the release of extracellular ATP through Cx43 hemichannels.

Possible role of hemichannels in cancer [PDF]

open access: yesFrontiers in Physiology, 2014
In humans, connexins (Cxs) and pannexins (Panxs) are the building blocks of hemichannels. These proteins are frequently altered in neoplastic cells and have traditionally been considered as tumor suppressors. Alteration of Cxs and Panxs in cancer cells can be due to genetic, epigenetic and post-transcriptional/post-translational events.

Astroglial Connexins in Neurodegenerative Diseases

open access: yesFrontiers in Molecular Neuroscience, 2021
Astrocytes play a crucial role in the maintenance of the normal functions of the Central Nervous System (CNS). During the pathogenesis of neurodegenerative diseases, astrocytes undergo morphological and functional remodeling, a process called reactive ...
