Abstract The S362A mutation block ROMK2 (Kir1.1b) endocytosis in Xenopus laevis oocyte membrane . Saeed Hajihashemi1 , 1-Assistant professor, PhD in Physiology, Department of Physiology, School of Medical science, Arak University of Medical Sciences. Introduction: ROMK channel is localized on the apical membrane of the nephron. Recent studies suggest that endocytosis of ROMK chan...

Defining retinal progenitor cell competence in Xenopus laevis by clonal analysis.

Extrinsic cues and intrinsic competence act in concert for cell fate determination in the developing vertebrate retina. However, what controls competence and how precise is the control are largely unknown. We studied the regulation of competence by examining the order in which individual retinal progenitor cells (RPCs) generate daughters. Experiments were performed in Xenopus laevis, whose full...

Expression of hsp90 Alpha and hsp90 Beta during Xenopus laevis Embryonic Development

Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...

Xenopus Primary Neurogenesis and Retinogenesis

In the past, significant advances in our understanding of vertebrate neurogenesis have been obtained using the amphibian model system Xenopus laevis. Today, Xenopus continues to serve as an excellent system to study the molecular mechanisms of neural cell fate determination and differentiation owing to the accessibility of the earliest events of neurogenesis, amenability of the organism to mani...
