UNLABELLED Guanylyl cyclase C (GC-C) is a transmembrane receptor expressed by human intestinal cells and primary and metastatic colorectal adenocarcinomas but not by extraintestinal tissues or tumors. The Escherichia coli heat-stable enterotoxin analog, STa (5--18), is a 14--amino acid peptide that selectively binds to the extracellular domain of GC-C with(More)
The purpose of this investigation was to provide evidence for the secretion of high molecular weight mucins, CTM-A and CTM-B, in primary culture of canine tracheal epithelial (CTE) cells. The cells were isolated from tracheas of mongrel dogs by pronase treatment. Primary cultures of the epithelial cells were established using ICN cellagen inserts in(More)
