Rare case of stomach and lung cancer displayed moderate cytoplasmic staining with additional membranous positivity in a case of ovarian cancer. Remaining cancer tissues were negative.
A few cases of gastric, ovarian, pancreatic and liver cancers displayed strong cytoplasmic immunoreactivity. The remaining tumor cells were negative.
GENE INFORMATION
Gene name
TFF2 (HGNC Symbol)
Synonyms
SML1
Description
Trefoil factor 2 (HGNC Symbol)
Entrez gene summary
Members of the trefoil family are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. They are stable secretory proteins expressed in gastrointestinal mucosa. Their functions are not defined, but they may protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium. The encoded protein inhibits gastric acid secretion. This gene and two other related trefoil family member genes are found in a cluster on chromosome 21. [provided by RefSeq, Jul 2008]
