The protocols outlined here hopefully will provide researchers with healthy, beautiful echinoderm oocytes, eggs, and embryos for experimental use. The large size of echinoderm oocytes and eggs, the ease with which they can be manipulated, and (in many species) their optical clarity, make them an ideal model system for studying not only the events specific(More)
Solar ultraviolet radiation (UVR, 290-400 nm) penetrates into seawater and can harm shallow-dwelling and planktonic marine organisms. Studies dating back to the 1930s revealed that echinoids, especially sea urchin embryos, are powerful models for deciphering the effects of UVR on embryonic development and how embryos defend themselves against UV-induced(More)
TITLE: Sex and microhabitat influence the allocation of mycosporine-like amino acids to tissues in the purple sea urchin, Strongylocentrotus purpuratus Field surveys of Strongylocentrotus purpuratus demonstrated that concentrations of natural sunscreens, mycosporine-like amino acids (MAAs), were higher in females than males for both gonadal and epidermal(More)
a r t i c l e i n f o Keywords: Proteome response Sea urchin embryo Two dimensional gel electrophoresis (2D GE) Ultraviolet radiation UVR We performed experiments to determine how environmentally relevant ultraviolet radiation (UVR) affects protein expression during early development in the sea urchin, Strongylocentrotus purpuratus. To model the(More)
Specialized membrane microdomains called rafts are thought to play a role in many types of cell-cell interactions and signaling. We have investigated the possibility that sea urchin eggs contain these specialized membrane microdomains and if they play a role in signal transduction at fertilization. A low density, TX-100 insoluble membrane fraction, typical(More)
