Regulation of connexin43 (Cx43) expression affects cell proliferation, differentiation and apoptosis in a gap junctional intercellular communication (GJIC)-independent manner. However, the underlying mechanisms of Cx43-mediated cell cycle suppression are still poorly understood. To elucidate the molecular mechanism of Cx43-mediated cell cycle suppression,(More)
Differential display screening for region-specific transcripts in rat brain revealed a novel striatum-specific transcript encoding an orphan G-protein-coupled receptor (GPCR) designated Strg/Gpr88 for striatum-specific GPCR. We isolated its homologues from human (HGMW-approved symbol GPR88) and mouse and mapped them to chromosomes 1p21.3 and 3G1,(More)
Heat shock protein 90 (Hsp90) has been demonstrated in both cytoplasm and nucleus, and regulates cytoplasmic retention of glucocorticoid receptor (GR). However, the role of nuclear Hsp90 in GR trafficking is less characterized. The present study examined the role of Hsp90 in nuclear retention of GR after ligand withdrawal. Hsp90 inhibitors; geldanamycin(More)
We developed a novel in vitro method for making nested deletions and applied it to a large-scale DNA sequencing. A DNA fragment to be sequenced (up to 15 kb long) was cloned with a new vector possessing two unique Sfi I sites, digested by Sfi I and ligated to generate a large head-to-tail concatemer. The large concatemer was randomly fragmented by(More)
The influenza virus replicates in the host cell nucleus, and the progeny viral ribonucleoprotein complex (vRNP) is exported to the cytoplasm prior to maturation. NS2 has a nuclear export signal that mediates the nuclear export of vRNP by the vRNP-M1-NS2 complex. We previously reported that the heat shock cognate 70 (Hsc70) protein binds to M1 protein and(More)
