  • Unique metabolic regulation of micromeres contributes to gastrulation in the sea urchin embryo

    Unique metabolic regulation of micromeres contributes to gastrulation in the sea urchin embryo

    Micromeres have a unique metabolic profile

    To test if micromeres have distinct metabolic properties, we performed metabolomics for micromeres and non-micromeres at the 16-cell stage of sea urchin (Strongylocentrotus purpuratus; Sp) embryos, using…

  • Structural insights into Type II-D Cas9 and its robust cleavage activity

    Structural insights into Type II-D Cas9 and its robust cleavage activity

    NsCas9d cleaves target DNA with minimal 20-nt complementarity

    To explore the diversity of Cas9 proteins, we selected 162 orthologs to construct a phylogenetic tree. The Type II-D Cas9s formed a distinct clade, showing a closer evolutionary…

    Towards a quality control framework for cerebral cortical organoids

    The stochastic nature of the differentiation of stem cells and their spontaneous self-organization within cerebral organoids leads to unpredictable variability among them1. Consequently, novel approaches have recently emerged to improve culture…

    APJR-βarr1 complexes with distinct stoichiometry

    To promote the assembly of a functional complex, we followed an established protocol for GPCR-βarr1 structural determination24. Briefly, the C-terminal segment (residues C331-D380) of the APJR was…
