    ..We present evidence that there may be partially redundant inputs into endoderm specification and that a subset of these genes appear also to function in determining cytoskeletal polarity in certain early blastomeres. ..

    ..This activation leads to phosphorylation of POP-1 and to apparent changes in its subcellular localization. Our findings provide evidence for novel regulatory avenues for an evolutionarily conserved Wnt/WG signaling pathway. ..

    ..briggsae end genes also function redundantly to specify endoderm. We propose that duplicated end genes have been maintained over long periods of evolution, owing in part to their synergistic function. ..

    ..We show that both PRY-1/Axin and the nuclear exportin homolog IMB-4/CRM-1 antagonize signaling. These findings reveal how Wnt signals direct the asymmetric localization of beta-catenin during polarized cell division. ..

    ..Defective mitotic spindle orientations in mom mutant embryos indicate that Wnt signaling influences cytoskeletal polarity in blastomeres throughout the early embryo. ..

    ..These findings highlight a role for a Fer-type kinase in setting the proper levels of Wnt signaling and demonstrate the importance of this modulation in ensuring appropriate cell division. ..
  9. Dudley N, Labbé J, Goldstein B. Using RNA interference to identify genes required for RNA interference. Proc Natl Acad Sci U S A. 2002;99:4191-6 pubmed
    ..The finding that genes predicted to encode proteins that associate with chromatin are involved in RNAi in C. elegans raises the possibility that chromatin may play a role in RNAi in animals, as it does in plants. ..
