Lung alveolar epithelial cells are comprised of type I (ATI) and type II (ATII) cells. ATI cells are polarized, although they have very flat morphology. The identification of marker proteins for apical and basolateral membranes of ATI cells is important to investigate into the differentiation of ATI cells. In this paper, we characterized receptor for(More)
The Ras-association domain family (RASSF) comprises six members (RASSF1-6) that each harbors a RalGDS/AF-6 (RA) and Sav/RASSF/Hippo (SARAH) domain. The RASSF proteins are known as putative tumor suppressors but RASSF6 has not yet been studied. We have here characterized human RASSF6. Although RASSF6 has RA domain, it does not bind Ki-Ras, Ha-Ras, N-Ras,(More)
Membrane-associated guanylate kinase inverted (MAGI)-1 plays a role as a scaffold at cell junctions in non-neuronal cells, while S-SCAM, its neuronal isoform, is involved in the organization of synapses. A search for MAGI-1-interacting proteins by yeast two-hybrid screening of a kidney cDNA library yielded dendrin. As dendrin was originally reported as a(More)
OBJECTIVES Actin-associated proteins at cell-matrix-contact sites form invadopodia in cancer cells and participate in migration, matrix degradation and invasion. We investigated an alteration of subcellular localization of invadopodia-related actin-associated proteins, actinin-1 and cortactin, in lung adenocarcinomas, its clinical significance, and its(More)
BACKGROUND AND OBJECTIVE The purpose of this study was to obtain an antibody that would be useful for investigating the yet unclear molecular mechanism underlying the differentiation of lung alveolar type I and II cells. METHODS Monoclonal antibodies were raised against membrane proteins from embryonal day 18.5 rat lungs and characterized by(More)
BACKGROUND AND STUDY AIMS Endoscopic retrograde cholangio- pancreatography with stone retrieval following endoscopic sphinc- terotomy (ES) is the standard method for the management of cho- ledocholithiasis. However, biliary stenting is used to treat patients with endoscopically irretrievable bile duct stones, especially elderly and high-risk patients. The(More)
