When Wnts antagonize Wnts
Secreted Wnt ligands appear to activate a variety of signaling pathways. Two papers in this issue now present genetic evidence that "noncanonical" Wnt signaling inhibits the "canonical" Wnt/beta-catenin pathway. Westfall et al. (2003a) show that zebrafish embryos lacking maternal Wnt-5 function are dorsalized due to ectopic activation of beta-catenin, whereas Topol et al. (2003) report that cho...
متن کاملCyanobacteria
Any embarrassing moments? Yes. In my first year as an assistant professor I was asked to give a talk in a neighboring department. They had just moved to a new building and I was the first speaker in their new auditorium. As I started my talk, we discovered that the auditorium was so new there weren't any light switches. I couldn't turn off the lights, and my slides were invisible. All those hou...
متن کاملStress response in cyanobacteria
Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...
متن کاملDoes nitrous oxide antagonize sevoflurane-induced hypnosis?
We have studied 64 ASA I and II patients (aged 20-60 yr) to determine if nitrous oxide affects sevoflurane requirement for achieving 50% probability of no movement in response to verbal commands (MACawake). Patients were allocated randomly to one of four nitrous oxide concentration groups (0, 20, 40 and 60 vol.%). Patients in each group received sevoflurane at two different end-tidal concentrat...
متن کاملDrICE resurrects Grim to antagonize DIAP1
Caspases (cysteine proteases) have been studied extensively over the past 2 decades for their roles in mediating cell death in multicellular organisms. They are typically activated as part of a proteolytic cascade, in which an initiator caspase is recruited, through its association with an adaptor protein, to a large multimeric caspaseactivating complex. Human caspase-9 and its Drosophila homol...
