Dev Reprod. 2015 Jun;19(2):69-77. doi: 10.12717/DR.2015.19.2.069.

Cell-cell direct communication through channel-forming molecules, connexin (Cx), is essential for a tissue to exchange signaling molecules between neighboring cells and establish unique functional characteristics during postnatal development. The corpus epididymis is a well-known androgen-responsive tissue and involves in...

Electrical coupling via gap junctions is an abundant phenomenon in the mammalian retina and occurs in all major cell types. Gap junction channels are assembled from different connexin subunits, and the connexin composition of the channel confers specific properties...

On Biophysical Properties and Sensitivity to Gap Junction Blockers of Connexin 39 Hemichannels Expressed in HeLa Cells.

Frontiers in physiology

Vargas AA, Cisterna BA, Saavedra-Leiva F, Urrutia C, Cea LA, Vielma AH, Gutierrez-Maldonado SE, Martin AJ, Pareja-Barrueto C, Escalona Y, Schmachtenberg O, Lagos CF, Perez-Acle T, Sáez JC.

Front Physiol. 2017 Feb 09;8:38. doi: 10.3389/fphys.2017.00038. eCollection 2017.

Although connexins (Cxs) are broadly expressed by cells of mammalian organisms, Cx39 has a very restricted pattern of expression and the biophysical properties of Cx39-based channels [hemichannels (HCs) and gap junction channels (GJCs)] remain largely unknown. Here, we used...

Prenatal nicotine exposure enhances Cx43 and Panx1 unopposed channel activity in brain cells of adult offspring mice fed a high-fat/cholesterol diet.

Frontiers in cellular neuroscience

Orellana JA, Busso D, Ramírez G, Campos M, Rigotti A, Eugenín J, von Bernhardi R.

Nicotine, the most important neuroteratogen of tobacco smoke, can reproduce brain and cognitive disturbances per se when administered prenatally. However, it is still unknown if paracrine signaling among brain cells participates in prenatal nicotine-induced brain impairment of adult offspring....

Roles of gap junctions, connexins, and pannexins in epilepsy.

Frontiers in physiology

EXCLI J. 2016 Feb 25;15:177-86. doi: 10.17179/excli2016-119. eCollection 2016.

Connexins and pannexins are key players in the control of cellular communication and thus in the maintenance of tissue homeostasis. Inherent to this function these proteins are frequently involved in pathological processes. The present paper reviews the role of...

Glioblastoma (GBM) is the most malignant primary brain tumor, with an average survival rate of 15 months. GBM is highly refractory to therapy, and such unresponsiveness is due, primarily, but not exclusively, to the glioma stem-like cells (GSCs). This...

Spatiotemporal changes in Cx30 and Cx43 expression during neuronal differentiation of P19 EC and NT2/D1 cells.

While connexins (Cxs) are thought to be involved in differentiation, their expression and role has yet to be fully elucidated. We investigated the temporal expression of Cx30, Cx36 and Cx43 in two in vitro models of neuronal differentiation: human...

Gap junctions are specialized regions of adjoining cell membranes composed of numerous intercellular low-resistance channels. In the heart, these channels electrotonically couple adjacent myocytes and synchronize the cardiac action potential. Signaling through gap junction channels may also influence embryogenesis...
