Building of Parhyale Hawaiensis Model

Arthropods are the most numerous and diverse animals on earth. Among them, pancrustaceans are an ancient and morphologically diverse group that includes a wide range of aquatic and semiaquatic crustaceans as well as insects that emerged from crustacean ancestors and colonized most terrestrial habitats. Among insects, Drosophila stands out as one of the most powerful animal models, making significant contributions to our understanding of development, physiology, and behavior. Given these properties, crustaceans provide fertile ground for exploring biodiversity through comparative studies. Recent advances in genetic manipulation and genome sequencing are paving the way for a new generation of research organisms. The marine amphipod Parhyale hawaiensis is the most established crustacean system available, offering year-round access to developmental stages, transgenic tools, genomic resources, and established genetics and imaging methods. Furthermore, Parhyale is easy to maintain and provides a large number of embryos suitable for injection, dissection, and in vivo imaging.

Highlights of Our Parhyale Hawaiensis Modeling Platform

Highlights of Our Parhyale Hawaiensis Modeling Platform
  • Our scientists have developed a detailed staging system to characterize the entire Parhyale embryogenesis, as well as robust protocols for in situ collection and fixation of all embryo stages for hybridization to study mRNA localization and immunohistochemistry to study protein localization.
  • Well-established techniques for the transient and transgenic introduction of recombinant genetic material, and the availability of endogenous promoters allow for a variety of gene misexpression experiments.
  • Targeted inhibition of gene function is possible using RNAi or morpholino approaches.
  • Important data for comparative studies aimed at understanding evolution of cis-regulation will be generated by directed genome sequencing.
