A majority of cancers showed weak to moderate cytoplasmic and occasional nuclear positivity. Additional membranous positivity was observed in endometrial cancers. Several cases of melanomas, colorectal and breast cancers showed strong immunoreactivity. Cases of liver, cervical, renal and lung cancers were negative.
Most cancer tissues showed weak to moderate cytoplasmic and/or nuclear immunoreactivity. Most cases of lymphomas, lung and liver cancers were negative.
A majority of cancer tissues showed weak to moderate cytoplasmic staining with additional membranous positivity in several cases. Thyroid cancers along with several colorectal, prostate, urothelial and liver cancers showed strong immunoreactivity. Several cases of lymphomas and gliomas were negative.
Moderate cytoplasmic positivity was observed in most cancers. Most lymphomas and testicular cancers as well as several urothelial cancers, basal and squamous cell carcinomas were weakly stained or negative.
GENE INFORMATION
Gene name
HERPUD1 (HGNC Symbol)
Synonyms
HERP, KIAA0025, Mif1, SUP
Description
Homocysteine-inducible, endoplasmic reticulum stress-inducible, ubiquitin-like domain member 1 (HGNC Symbol)
Entrez gene summary
The accumulation of unfolded proteins in the endoplasmic reticulum (ER) triggers the ER stress response. This response includes the inhibition of translation to prevent further accumulation of unfolded proteins, the increased expression of proteins involved in polypeptide folding, known as the unfolded protein response (UPR), and the destruction of misfolded proteins by the ER-associated protein degradation (ERAD) system. This gene may play a role in both UPR and ERAD. Its expression is induced by UPR and it has an ER stress response element in its promoter region while the encoded protein has an N-terminal ubiquitin-like domain which may interact with the ERAD system. This protein has been shown to interact with presenilin proteins and to increase the level of amyloid-beta protein following its overexpression. Alternative splicing of this gene produces multiple transcript variants encoding different isoforms. The full-length nature of all transcript variants has not been determined.
