Dominant regulation of interendothelial cell gap formation

Acute transitions in cytosolic calcium ([Ca2+]i) through store-operated calcium entry channels catalyze interendothelial cell gap formation that increases permeability. However, the rise in [Ca2+]i only disrupts barrier function in the absence of a rise in cAMP. Discovery that type 6 adenylyl cyclas

Cell cycle dependent regulation of gap junction coupling

tabolic state of the cells, it is postulated that gap junction coupling of GFSHR-17 granulosa cells could be modif- ied during the cell cycle. Furthermore, it was shown that the induction of apoptosis is partly related to the degree of gap junction coupling [10]. If the degree of gap junct- ion coupling’s regulation is dependent upon the cell cy-

GEFs and GAPs: Critical Elements in the Control of Small G

Jun 01, 2007· The Rho family is mainly involved in the regulation of cell shape, the cytoskeleton, and cell migration, whereas Ras family members regulate a variety of signaling pathways, resulting in transcription and cellular differentiation and proliferation. The large number of G proteins requires a multitude of GEFs and GAPs to ensure signaling specificity.

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is

Regulation of collective cell migration by RhoGAP myosin IXA

Cell-cell contact formation in 16HBE cells is controlled by myosin IXA. Protrusive lamellipodia collide and overlap leading to accumulation of junctional actin (red dots). Myosin IXA is recruited at this time and the GAP domain reduces Rho activity at contact zones allowing the formation of radial actin bundles (red diagonal lines).

"Down-regulation of membrana granulosa cell gap junctions

One of the currently popular hypotheses for the regulation of meiotic resumption in mammalian oocytes proposes that the preovulatory surge of luteinizing hormone causes down-regulation of follicular gap junctions, which in turn disrupts transfer of a meiotic arrester from the somatic cells into the oocyte. The present study has investigated this hypothesis by examining the integrity

Regulation of gap junction channels and hemichannels by

May 24, 2016· Post-translational modifications of connexins play an important role in the regulation of gap junction and hemichannel permeability. The prerequisite for the formation of functional gap junction channels is the assembly of connexin proteins into hemichannels and their insertion into the membrane. Hemichannels can affect cellular processes by enabling the

Regulation of Gap-Junctional Communication Between Cumulus

Aug 01, 2012· Introduction. Intercellular gap-junctional communication (GJC) plays a key role in ovarian follicle physiology. Its role during oocyte maturation in mammalian cumulus complexes has been recently reviewed by Gershon [].Present in most animal cells other than differentiated skeletal muscle cells, erythrocytes, and mature sperm cells [], gap junctions are channels that

Spatial and temporal regulation of gap junction connexin43

Hemodynamic regulation of the endothelial gap junction protein connexin43 (Cx43) was studied in a model of controlled disturbed flows in vitro . Cx43 mRNA, protein expression, and intercellular communication were mapped to spatial variations in fluid forces. Hemodynamic features of atherosclerotic lesion-prone regions of the vasculature (flow separation and

Ser364 of connexin43 and the upregulation of gap junction

Dec 24, 2001· Gap junction (GJ) * proteins (termed connexins [Cxs]), comprise a family of vertebrate transmembrane proteins that assemble intracellularly to form oligomeric channels (Musil and Goodenough, 1993).The GJ hemichannels, or connexons, are transported to the plasma membrane where they dock with connexons in the membranes of adjacent cells and

Granulosa cells regulate intracellular pH of the murine

Oocytes grow within ovarian follicles in which the oocyte is coupled to the surrounding granulosa cells by gap junctions. It was previously found that small growing oocytes isolated from juvenile mice and freed of their surrounding granulosa cells (denuded) lacked the ability to regulate their intracellular pH (pHi), did not exhibit the pHi-regulatory HCO3-/Cl- and Na+/H+ exchange

Gap junctions and other mechanisms of cell-cell

Cell-cell communication in the islet of Langerhans is important for the regulation of insulin secretion. Gap-junctions coordinate oscillations in intracellular free-calcium ([Ca(2+)](i)) and insulin secretion in the islet following elevated glucose. Gap-junctions can also ensure that oscillatory [Ca(2+)](i) ceases when glucose is at a basal levels.
