Abstract

In this study, we demonstrate by a variety of approaches (ie, morphological analysis, Western blots, immunolocalization, and the use of specific antibodies) that hyperosmotic deciliation stress of sea urchin embryos induces a thermotolerant response. Deciliation is also able to activate a phosphorylation signaling cascade the effector of which might be the p38 stress-activated protein kinase because we found that the administration of the p38 inhibitor SB203580 to sea urchin deciliated gastrula embryos makes the hyperosmotic deciliation stress lethal.
