Using an autoimmune serum from a patient with overlap connective tissue disease we have identified by biochemical and immunocytochemical approaches an evolutionarily conserved nuclear pore complex (NPC) protein with an estimated molecular mass of 180 kD and an isoelectric point of approximately 6.2 which we have designated as nup180. Extraction of isolated(More)
A partial cDNA clone coding for the mouse homologue of the human Ran-GTP binding protein, RanBP2, has been isolated by screening of a murine expression library with antibodies to nup180, a previously identified nuclear pore complex protein (nucleoporin). Whether the antibodies cross-reacted with the polypeptide encoded by the cDNA clone or, alternatively,(More)
Import of DNA from the cytoplasm into the mitochondrial matrix is an obligatory step for an in organello site-directed mutagenesis or gene therapy approach on mitochondrial DNA diseases. In this context, we have developed an artificial DNA translocation vector that is composed of the mitochondrial signal peptide of the ornithine transcarbamylase (OTC) and a(More)
Editorial Comment: Testosterone therapy for late-onset hypogonadism is a controversial practice. What is not controversial is the need for appropriate patient selection and careful monitoring for treatment emergency adverse events in those patients who do choose to initiate testoster-one therapy. While individual practitioners may vary in the details of(More)
