ABSTRACT
The actin-based cytoskeleton is considered a fundamental driving force for cell differentiation and development. Destrin (Dstn), a member of the actin-depolymerizing factor family, regulates actin dynamics by treadmilling actin filaments and increasing globular actin pools. However, the specific developmental roles of dstn have yet to be fully elucidated. Here, we investigated the physiological functions of dstn during early embryonic development using Xenopus laevis as an experimental model organism. dstn is expressed in anterior neural tissue and neural plate during Xenopus embryogenesis. Depleting dstn promoted morphants with short body axes and small heads. Moreover, dstn inhibition extended the neural plate region, impairing cell migration and distribution during neurulation. In addition to the neural plate, dstn knockdown perturbed neural crest cell migration. Our data suggest new insights for understanding the roles of actin dynamics in embryonic neural development, simultaneously presenting a new challenge for studying the complex networks governing cell migration involving actin dynamics.
