Essential Role of Glycosaminoglycans in Fgf Signaling during Mouse Gastrulation

In vitro studies have suggested that proteoglycans facilitate signaling by mammalian growth factors, but genetic evidence supporting this role has been lacking. Here, we characterize the ENU-induced mutation lazy mesoderm (lzme), which disrupts the single mouse gene encoding UDP-glucose dehydrogenase (Ugdh), an enzyme required for the synthesis of the glycosaminoglycan (GAG) side chains of prot...

Essential role of CREB family proteins during Xenopus embryogenesis

The leucine zipper transcription factors cAMP response element binding protein (CREB), cAMP response element modulatory protein (CREM) and activating transcription factor 1 (ATF1) bind to the cAMP response element (CRE) with the palindromic consensus sequence TGACGTCA. Their transcriptional activities are dependent on serine phosphorylation induced by various extracellular signals such as hormo...

Essential role of Apelin signaling during lymphatic development in zebrafish.

OBJECTIVE Apelin and its cognate receptor Aplnr/Apj are essential for diverse biological processes. However, the function of Apelin signaling in lymphatic development remains to be identified, despite the preferential expression of Apelin and Aplnr within developing blood and lymphatic endothelial cells in vertebrates. In this report, we aim to delineate the functions of Apelin signaling during...

Electric discharge during electrosurgery

Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a ...
