The mechanism by which cells increase their rate of glucose uptake in response to stress is unclear. Using an immunofluorescence technique to localize the glucose transporter protein in BHK cells, we found that hyperthermia, treatment with arsenite, infection with vesicular stomatitis virus or Semliki Forest virus, and treatment with insulin cause the(More)
The node of Ranvier is a complex macromolecular assembly of ion channels and other proteins that is specialized for the rapid propagation of the action potential. A full understanding of the processes responsible for the assembly and maintenance of the node requires first the identification and characterization of the proteins found there. Here we show that(More)
ENDOGLIN (ENG) is a co-receptor for transforming growth factor-β (TGF-β) family members that is highly expressed in endothelial cells and has a critical function in the development of the vascular system. Mutations in Eng are associated with the vascular disease known as hereditary hemorrhagic telangiectasia type l. Using mouse embryonic stem cells we(More)
