✦ Synopsis

Signal transduction pathways are largely conserved throughout the animal kingdom. The repertoire of pathways is limited and each pathway is used in different intercellular signaling events during the development of a given animal. For example, Wnt signaling is recruited, sometimes redundantly with other molecular pathways, in four cell specification events during Caenorhabditis elegans vulva development, including the activation of vulval differentiation. Strikingly,a recent study finds that Wnts act to repress vulval differentiation in the nematode Pristionchus pacificus,1 demonstrating evolutionary flexibility in the use of intercellular signaling pathways.

Karyotypic variation in five gibbon species of the subgenus Hylobates (2n ϭ 44) was assessed in 63 animals, 23 of them wild born. Acquisition of key specimens of Hylobates agilis (agile gibbon), whose karyotype had been problematic due to unresolved structural polymorphisms, led to disclosure of a c

While screening for new mutations in the HEXB gene, which encodes the beta-subunit of beta-hexosaminidase, a TG deletion (deltaTG) was found in the 3' untranslated region (3'UTR) of the gene, 7 bp upstream from the polyadenylation signal. Examination of DNA samples of 145 unrelated Argentinean indiv
