A majority of cancer tissues showed a weak to moderate cytoplasmic positivity with distinct extracellular staining. Several cases of ovarian cancers and a few cases of prostate, testis, urothelial and renal cancers displayed moderate cytoplasmic immunoreactivity with distinct extracellular staining.

Description
Stanniocalcin 1 (HGNC Symbol)
Entrez gene summary
This gene encodes a secreted, homodimeric glycoprotein that is expressed in a wide variety of tissues and may have autocrine or paracrine functions. The gene contains a 5' UTR rich in CAG trinucleotide repeats. The encoded protein contains 11 conserved cysteine residues and is phosphorylated by protein kinase C exclusively on its serine residues. The protein may play a role in the regulation of renal and intestinal calcium and phosphate transport, cell metabolism, or cellular calcium/phosphate homeostasis. Overexpression of human stanniocalcin 1 in mice produces high serum phosphate levels, dwarfism, and increased metabolic rate. This gene has altered expression in hepatocellular, ovarian, and breast cancers. [provided by RefSeq, Jul 2008]
