Selenium is important for embryogenesis in vertebrates but little is known about the
expression patterns and biological functions of most selenoprotein genes. Taking advantage
of the zebrafish model, systematic analysis of selenoprotein gene expression was performed
by in situ hybridization on whole-mount embryos at different developmental stages. Twenty-
one selenoprotein mRNAs were analyzed and all of them exhibited expression patterns
restricted to specific tissues. Moreover, we demonstrated that highly similar selenoprotein …
