Immunohistochemistry using an antibody to unphosphorylated connexin 43 to identify human myometrial interstitial cells

Reproductive Biology and Endocrinology, 2008
Background Myometrial smooth myocytes contract as a result of electrical signalling via a process called excitation-contraction coupling. This process is understood in great detail at the cellular level but the generation and coordination of electrical ...

Yunweiling alleviates functional constipation: integrating network pharmacology and experimental study

Animal Models and Experimental Medicine, EarlyView.
In a study combining network pharmacological analysis and experimental verification, yunweiling has been shown improve functional constipation by inhibiting the PI3K‐Akt‐p53 signaling pathway and reducing the expression of TP53. Abstract Background This study investigated the impacts and mechanisms of yunweiling in the management of Functional ...

Nitric oxide enhances de novo formation of endothelial gap junctions [PDF]

, 2003
Objective: Gap junctions (formed by connexins, Cx) are important for functional coordination of cells in the vascular wall. However, little is known about their physiological regulation in this tissue.

Antidepressants Impact Connexin 43 Channel Functions in Astrocytes

Frontiers in Cellular Neuroscience, 2016
Glial cells, and in particular astrocytes, are crucial to maintain neuronal microenvironment by regulating energy metabolism, neurotransmitter uptake, gliotransmission, and synaptic development.

Cx26 drives self-renewal in triple-negative breast cancer via interaction with NANOG and focal adhesion kinase

Nature Communications, 2018
Connexin proteins are usually considered as tumor suppressors. Here, the authors show that connexin 26 (Cx26) regulates the self-renewal of breast cancer stem cells via a ternary complex with FAK and NANOG.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Diversity in connexin biology

Journal of Biological Chemistry, 2023
Over 35 years ago the cell biology community was introduced to connexins as the subunit employed to assemble semicrystalline clusters of intercellular channels that had been well described morphologically as gap junctions. The decade that followed would see knowledge of the unexpectedly large 21-member human connexin family grow to reflect unique and ...

Connexons and pannexons: newcomers in neurophysiology

Frontiers in Cellular Neuroscience, 2014
Connexin hemichannels are single membrane channels which have been traditionally thought to work in pairs to form gap junction channels across two opposing cells.

Synchronization in Electrically Coupled Neural Networks [PDF]

arXiv, 2006
In this report, we investigate the synchronization of temporal activity in an electrically coupled neural network model. The electrical coupling is established by homotypic static gap-junctions (Connexin 43). Two distinct network topologies, namely: {\em sparse random network, (SRN)} and {\em fully connected network, (FCN)} are used to establish the ...

Insulin and Metformin are Associated With Reduced Risk of Amyotrophic Lateral Sclerosis

Chronic Diseases and Translational Medicine, EarlyView.
Human insulin heterodimer (A). Human insulin heterodimer (dark blue) docked within center of Cx43 channel (B) Abstract Background Type 2 diabetes (T2D), but not type 1, protected against amyotrophic lateral sclerosis (ALS). In T2D serum insulin is normal or elevated in the early stages.
