Most malignant cells displayed weak to moderate cytoplasmic and membranous positivity or were negative. Most colorectal and several renal, stomach and pancreatic cancers were strongly stained.
Most malignancies displayed moderate to strong cytoplasmic immunoreactivity in a fraction of tumor cells. The majority of malignant gliomas, melanomas, prostate and liver cancers were negative.
GENE INFORMATION
Gene name

Description
Amine oxidase, copper containing 1 (HGNC Symbol)
Entrez gene summary
This gene encodes a metal-binding membrane glycoprotein that oxidatively deaminates putrescine, histamine, and related compounds. The encoded protein is inhibited by amiloride, a diuretic that acts by closing epithelial sodium ion channels. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2013]
