The teratogenic and growth-inhibiting potential of DNA, RNA, and protein synthesis inhibitors was explored using the Frog Embryo Teratogenesis Assay: Xenopus (FETAX). Endpoints measured in 96-h static tests were survival, malformation, ability to swim, skin pigmentation, stage of development, and growth. The DNA synthesis inhibitors hydroxyurea, cytosine(More)
We have developed an assay that measures the inhibition of protein synthesis and can be used in conjunction with a whole embryo bioassay that detects the ability of a chemical to cause fetotoxicity, malformation and abnormal growth. The assay involves microinjecting the herpes thymidine kinase gene into stage 6 oocytes of Xenopus laevis then exposing the(More)
Calpains are a family of intracellular proteases defined by a conserved protease domain. In the marine mollusk Aplysia californica, calpains are important for the induction of long-term synaptic plasticity and memory, at least in part by cleaving protein kinase Cs (PKCs) into constitutively active kinases, termed protein kinase Ms (PKMs). We identify 14(More)
