Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Managing the complexity of communication; regulation of gap junctions by post-translational modification

Frontiers in Pharmacology, 2013
Gap junctions are comprised of connexins that form cell-to-cell channels which couple neighboring cells to accommodate the exchange of information.

Cx43 and the Actin Cytoskeleton: Novel Roles and Implications for Cell-Cell Junction-Based Barrier Function Regulation

Biomolecules, 2020
Barrier function is a vital homeostatic mechanism employed by epithelial and endothelial tissue. Diseases across a wide range of tissue types involve dynamic changes in transcellular junctional complexes and the actin cytoskeleton in the regulation of ...

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

Advanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

Gap junctions and communication within the nervous system

Brazilian Journal of Veterinary Pathology, 2008
Gap junctions are sites on the cellular membrane with intercellular channels build up by twelve protein subunits called connexins. Each connected cell contributes with a hemichannel made up by six connexins subunits.

Distinct Connexin43, Connexin31, and Pannexin1 expression patterns in the cochlea of a non-human primate. [PDF]

Sci Rep
Membrane channels play an important role in auditory processes. Connexins and pannexins are membrane channels that exist in the cochlea. Connexin26 and connexin30 have been previously shown to be differentially expressed in the developing cochlea of ...

Coaxially Electrospun Myocardial dECM‐ Based Nanofibrous Scaffolds Demonstrate Enhanced Cardiomyocyte Biocompatibility

Advanced Healthcare Materials, EarlyView.
Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.

Connexin 43‐Enriched Vesicles Improve Synchronization in hiPSC‐Derived Cardiomyocytes

Advanced Science, EarlyView.
Plasma membrane‐derived Connectosomes enriched in connexin‐43 are produced from donor hiPSCs and applied to hiPSC‐derived cardiomyocytes (hiPSC‐CMs). Connexin‐43 channels on Connectosomes remain functional, strengthening intercellular electrochemical coupling and increasing network synchronization over time.

Connexins and Nitric Oxide Inside and Outside Mitochondria: Significance for Cardiac Protection and Adaptation

Frontiers in Physiology, 2018
Irreversible myocardial damage happens in the presence of prolonged and severe ischemia. Several phenomena protect the heart against myocardial infarction and other adverse outcomes of ischemia and reperfusion (IR), namely: hibernation related to stunned

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 ...
