Research Abstract

In this research project in cooperation with Dr. Fred Wilt of the California University, we performed a series of study to elucidate a gene cascade regulating morphogenesis of sea urchin embryos, and obtained following results. 1. Expression of HpEts gene that regulated expression of genes encoding spicule matrix proteins is activated at the blastula stage. HpEts contains T domain in its 5' UTR. 2. cDNA of HpTbr, a sea urchin homolog of Tbr, was cloned. HpTbr cDNA becomes first detectable in pre-hatching blastulae and disappears after mesenchyme blastulae. Site of its expression is restricted to primary mesenchyme cells that specifically expresses HpEts, suggesting that HpTbr is related to regulation of transcription of HpEts gene. 3. HpLim, a sea urchin homolog of XLim, is transiently expressed in the vegetal half of the blastulae, and the embryos that express HpLim throughout the whole body by introduction of a large amount of HpLim mRNA in to eggs failed to form neither endoderm and mesoderm nor the oral and aboral axis. This suggests that HpLim is related to a vegetal signalling system needed for dorsoventral axis formation.
