Building of Sea Urchin Model

Sea urchins belong to the class Echinodermata Echinacea and are an early model organism, and its larval development model is an excellent model for studying biological adaptive evolution. The purple Strongylocentrotus purpuratus has been used as a model organism in developmental biology for more than 150 years. Application of this model species, scientists have been able to describe cell cycle control and mechanisms of cell adhesion, fertilization, calcium signaling, cell differentiation, and death in detail. Biologists have been using sea urchin embryos as prototypes to study the developmental mechanisms that help establish the embryo's body plan. Massively parallel sequencing of the sea urchin genome enables deciphering major components of gene regulatory networks during embryonic signaling pathway activation. In addition, sea urchin embryos have played an important role as models in the study of neurodegenerative diseases that can lead to dementia and memory loss.

Our Services

Scientists at CD BioSciences have amassed a vast understanding of sea urchin biology and their experimental manipulations. We combine this expertise with data analytics solutions. Building on this foundation, we offer a comprehensive portfolio of toxicity, genetics and efficacy services: disease modeling, target validation, drug efficacy screening and chemical safety assessment.

  • Gene functional analyses in sea urchin
    We will use over-representation analysis (ORA) and functional class scoring (FCS) methods to identify potential pathways associated with our gene list.
    • Differential expression analysis
    • GWAS analysis
    • Proteomic analysis
  • Sea urchin developmental toxicity tests
    The first step in understanding the biological effects of a compound on any organism is to establish a dose-response relationship to provide a dose of the compound that can be used for subsequent toxicological evaluation. Our scientists provide clients with modeling and optimization of sea urchin concentration-response data.
  • Gene knockout in sea urchin
    Our scientists knock out sea urchins using the CRISPR/Cas9 system.

Our Knockout Technology in Sea Urchin Research

CRISPR/Cas9 is based on bacteria's defense system against viruses, and it allows scientists to easily and frequently design low-cost constructs. Our scientists knocked out sea urchins using the CRISPR/Cas9 system. CRISPR/Cas9 is able to more precisely identify changes in gene function, and we can confirm the DNA sequence of target in the genome.
