Protein 4.1 (also called band 4.1 or simply 4.1) was originally identified as an abundant protein of the human erythrocyte, in which it stabilizes the spectrin/actin cytoskeleton. The protein and its relatives have since been found in many cell types of metazoan organisms and they are often concentrated in the nucleus, as well as in cell-cell junctions.(More)
Proteins of the 4.1 family play a key role in the integrity of the cytoskeleton and in epithelial tissue movement, as shown by the disruption of the actin cytoskeleton in human erythrocytes caused by genetic loss of protein 4.1, and the failure of epithelial tissue migration during Drosophila embryogenesis caused by genetic loss of the 4.1 homolog Coracle.(More)
Membrane-associated guanylate kinase homologs (MAGUKs) may play a role in cellular functions preventing tumorigenesis as indicated by the neoplastic phenotype caused by genetic loss of the MAGUK Dlg in Drosophila. To test this possibility, we examined the expression and subcellular localization of the tight junction MAGUK ZO-1, as well as the cell adhesion(More)
We have determined the cDNA sequence, expression pattern, and chromosomal location of the human gene DLG4, encoding the postsynaptic density-95 (PSD95) protein. hPSD95 is a 723-amino-acid protein that is 99% identical to its rodent counterparts. This is the fourth human protein identified as showing significant similarity to the Drosophila tumor suppressor(More)
INTRODUCTION ZO-1 is a tight junction membrane protein that plays a critical role in cell-cell interaction, proliferation, and differ entiation. AIM To localize and evaluate the expression of ZO-1 in the normal human pancreas, in pancreatic ductal adenocarcinoma (PDAC), and in chronic pancreatitis (CP). METHODOLOGY AND RESULTS Northern and Western blot(More)
Langerhans cell histiocytosis (LCH) is a complex disease entity comprised of three distinct clinical syndromes that demonstrate indistinguishable histology. These syndromes are: eosinophilic granuloma, which is predominantly osseous or pulmonary; Hand-Schûller-Christian’s disease, which involves multiple organ systems and, most typically, the skull base;(More)
Multiple radiographic acquisition techniques have been evaluated for their effect on measurements of acetabular morphology. This cadaveric study examined the effect of two acquisition parameters not previously evaluated: beam center position and source-to-detector distance. This study also evaluated the effect of reader differences on measurements.(More)
