Most cancer cells exhibited weakly stained nuclei or were negative. Colorectal, ovarian and a few cases of pancreatic and gastric carcinomas exhibited distinct membranous positivity.
Most cancer cells were negative. Colorectal cancers as well as several cases of cholangiocarcinomas, stomach and pancreatic cancers expressed strong cytoplasmic and membranous immunoreactivity.
Cancer tissues were in general negative. Colorectal cancers and several cases of stomach cancers displayed strong cytoplasmic and membranous positivity.
Most cancer tissues were negative. Strong membranous and cytoplasmic staining was observed in all colorectal cancers while several cases of cholangiocarcinomas, gastric, pancreatic and ovarian cancers displayed moderate to strong immunoreactivity.
GENE INFORMATION
Gene name
CDH17 (HGNC Symbol)

cadherin, HPT-1
Description
Cadherin 17, LI cadherin (liver-intestine) (HGNC Symbol)
Entrez gene summary
This gene is a member of the cadherin superfamily, genes encoding calcium-dependent, membrane-associated glycoproteins. The encoded protein is cadherin-like, consisting of an extracellular region, containing 7 cadherin domains, and a transmembrane region but lacking the conserved cytoplasmic domain. The protein is a component of the gastrointestinal tract and pancreatic ducts, acting as an intestinal proton-dependent peptide transporter in the first step in oral absorption of many medically important peptide-based drugs. The protein may also play a role in the morphological organization of liver and intestine. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]
