Malignant cells showed in general weak to moderate cytoplasmic and additional nuclear staining. Malignant lymphomas, prostate and testicular cancers were weakly stained or negative. Cholangiocarcinomas were stained whereas hepatocellular carcinomas were negative.
Most malignant tissues showed weak to moderate nuclear and cytoplasmic positivity. Several urothelial and colorectal cancers along with a few pancreatic cancers exhibited strong immunoreactivity. Malignant lymphomas, prostate, breast and testicular cancers along with several hepatocellular carcinomas and endometrial cancers were negative.

S100A6 (HGNC Symbol)
Synonyms
2A9, CABP, CACY, PRA
Description
S100 calcium binding protein A6 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in stimulation of Ca2+-dependent insulin release, stimulation of prolactin secretion, and exocytosis. Chromosomal rearrangements and altered expression of this gene have been implicated in melanoma. [provided by RefSeq, Jul 2008]
