Plasma membrane-associated sialidase is a key enzyme for ganglioside hydrolysis, thereby playing crucial roles in regulation of cell surface functions. Here we demonstrate that mice overexpressing the human ortholog (NEU3) develop diabetic phenotype by 18-22 weeks associated with hyperinsulinemia, islet hyperplasia, and increased beta-cell mass. As compared(More)
Sialic acids are acidic monosaccharides that bind to the sugar chains of glycoconjugates and change their conformation, intermolecular interactions, and/or half-life. Thus, sialidases are believed to modulate the function of sialoglycoconjugates by desialylation. We previously reported that the membrane-associated mammalian sialidase NEU3, which(More)
Intraepithelial neoplasias are preinvasive neoplastic lesions found throughout in the digestive system, and when such lesions are discovered in the gallbladder, they are referred to as intracystic papillary neoplasm (ICPN). In the gallbladder, mucinous adenocarcinoma is a rare histologic phenotype, and adenocarcinomas involving Rokitansky-Aschoff (RA)(More)
