Architecture and evolution of the cis-regulatory system of the echinoderm kirrelL gene
Published 2022-02-01“…In this study, we dissected the transcriptional control region of the kirrelL gene of the purple sea urchin, Strongylocentrotus purpuratus. Using plasmid- and bacterial artificial chromosome-based transgenic reporter assays, we identified key cis-regulatory elements (CREs) and transcription factor inputs that regulate Sp-kirrelL, including direct, positive inputs from two key transcription factors in the skeletogenic GRN, Alx1 and Ets1. …”

Single-Cell Transcriptomic Analysis Reveals the Molecular Profile of Go-Opsin Photoreceptor Cells in Sea Urchin Larvae
Published 2023-08-01“…To answer these questions, we combined immunohistochemistry and fluorescent in situ hybridization to investigate how the Opsin3.2 PRCs develop in the sea urchin <i>Strongylocentrotus purpuratus</i> larva. Subsequently, we applied single-cell transcriptomics to investigate the molecular signature of the <i>Sp-Opsin3.2</i>-expressing cells and show that they deploy an ancient regulatory program responsible for photoreceptors specification. …”

Comparative genomics of neuroglobin reveals its early origins.
Published 2012-01-01“…Despite its high sequence conservation among vertebrates Ngb seems to be elusive in invertebrates.We determined candidate orthologs in invertebrates and identified a globin of the placozoan Trichoplax adhaerens that is most likely orthologous to vertebrate Ngb and confirmed the orthologous relationship of the polymeric globin of the sea urchin Strongylocentrotus purpuratus to Ngb. The putative orthologous globin genes are located next to genes orthologous to vertebrate POMT2 similarly to localization of vertebrate Ngb. …”
