  • Xenopus Lab Survey

    Do you work with Xenopus?
    If your answer is YES, then we need to hear from you!!!

    We want to know 3 basic things about Xenopus research.
    * How many Xenopus labs and researchers are there in the world?
    * How many Xenopus frogs are used in research?  
    * How frequently do you ovulate your frogs?

    The survey will take less than 3 minutes.

    Survey closes October 31st, so don't delay, fill it in today!

  • New X. laevis 9.2 and X. tropicalis 9.1 GFFs

    Xenbase GFF tracks for X. laevis 9.2 and X. tropicalis 9.1 official genomes are now available on Xenbase FTP and GitLab account!

    View on JBrowse: trop and laevis.
     
    GFFs were created by merging NCBI and JGI GFF files.

  • The brain is required for normal muscle and nerve patterning during early Xenopus development

    Herrera-Rincon et al. published in Naure Communications their use of an amputation assay in Xenopus laevis to show that absence of brain alters subsequent muscle and peripheral nerve patterning during early development. This phenotype can be rescued by modulating bioelectric signals.

  • Comprehensive analyses of hox gene expression in Xenopus laevis embryos and adult tissues

    Kondo et al. published in Developement, Growth, and Differentiation their analysis of two homeologous sets (L and S) of four hox gene clusters A through D and 13 paralogous groups. Read the article to see the expression of 76 genes during developement and in adult tissues.
