Summary
Connexins (Cxs) are key proteins in blood vessels, facilitating cell communication for vascular health. New research highlights their crucial role in forming microvascular networks and regulating blood vessel growth (angiogenesis).
Area of Science:
- Vascular Biology
- Cellular Signaling
- Molecular Medicine
Background:
- Connexins (Cxs) form gap junction channels, essential for intercellular communication in endothelial cells (ECs).
- ECs use Cx channels to maintain vascular homeostasis, particularly in large arteries.
- Emerging evidence points to Cxs' role in microvascular network formation.
Purpose of the Study:
- To investigate the role of endothelial connexins (Cxs) in microvascular network formation.
- To explore how Cxs regulate physiological and pathological angiogenesis.
- To identify endothelial Cxs as potential therapeutic targets for angiogenesis control.
Main Methods:
- Analysis of developmental and pathological models.
- Investigation of canonical and noncanonical functions of endothelial Cxs.
Main Results:
- Endothelial Cxs are critical for the coordinated response of ECs to stimuli during angiogenesis.
- Cxs regulate both physiological and pathological blood vessel formation.
- Studies reveal diverse functions of Cxs beyond simple channel formation.
Conclusions:
- Endothelial Cxs play a significant role in regulating angiogenesis.
- Targeting Cxs offers a promising strategy for controlling aberrant blood vessel growth.
- Further research into Cxs' functions can advance therapeutic approaches for vascular diseases.

Regulation of Angiogenesis and Blood Supply
2.8K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Mechanism of Angiogenesis
6.0K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Gap Junctions
8.4K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Overview of Cell-Matrix Interactions
7.7K
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Notch Signaling Pathway
4.5K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Contact-dependent Signaling
45.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
