Hepatocyte growth factor (HGF) was recently recognized as a potential neurotrophic factor in the developing brain. We studied expression of HGF and its receptor using Northern blot analysis and in situ hybridization for mRNA and double immunofluorescent laser confocal microscopy. HGF and cMet messages were abundant in the hippocampus of both human and rat(More)
We prepared several monoclonal antibodies (mAbs) specific for the NH2- and COOH-terminal regions of the DNA helicase (WRN helicase) responsible for Werner's syndrome known as a premature aging disease. With these antibodies, we detected by immunoblot analysis the endogenous WRN helicase of a relative mass of 180 kD in several lines of cultured cells, but(More)
We show that WRN helicase contains a unique 5'-->3' exonuclease activity in the N-terminal region. Adeletion mutant lacking 231 N-terminal amino acid residues, made in a baculovirus system, did nothave this activity, while it showed ATPase and DNA helicase activities. This exonuclease activity was co-precipitated with the helicase activity using monoclonal(More)
