Interactions between mitogen-activated protein kinase and protein kinase C signaling during oocyte maturation and fertilization in a marine worm.

30 Jul 2009 In the marine nemertean worm Cerebratulus, follicle-free oocytes re-initiate meiosis and undergo nuclear disassembly (=germinal vesicle breakdown, GVBD) after being stimulated to mature by seawater (SW) or cAMP-elevating drugs. Previously, it has ... Read more...

Measuring Ca2+-signalling at fertilization in the sea urchin Psammechinus miliaris: alterations of this Ca2+-signal by copper and 2,4,6-tribromophenol.

16 May 2009 During fertilization, eggs undergo a temporary rise in the intracellular concentration of free Ca(2+) ions. Using the membrane permeable acetoxymethylester of the fluorescent calcium indicator dye Fura-2, Fura-2 AM, the Ca(2+)-signal at ... Read more...

Beta1 integrin is an adhesion protein for sperm binding to eggs.

13 May 2009 We investigated the role of beta(1) integrin in mammalian fertilization and the mode of inhibition of fertilinbeta-derived polymers. We determined that polymers displaying the Glu-Cys-Asp peptide from the fertilinbeta disintegrin domain mediate ... Read more...
