Most cancer tissues displayed weak to moderate cytoplasmic positivity which in several cases was combined with additional nuclear staining. Several gliomas, lymphomas and urothelial cancers were negative.
GENE INFORMATION
Gene name
SLC29A1 (HGNC Symbol)
Synonyms
ENT1
Description
Solute carrier family 29 (equilibrative nucleoside transporter), member 1 (HGNC Symbol)
Entrez gene summary
This gene is a member of the equilibrative nucleoside transporter family. The gene encodes a transmembrane glycoprotein that localizes to the plasma and mitochondrial membranes and mediates the cellular uptake of nucleosides from the surrounding medium. The protein is categorized as an equilibrative (as opposed to concentrative) transporter that is sensitive to inhibition by nitrobenzylthioinosine (NBMPR). Nucleoside transporters are required for nucleotide synthesis in cells that lack de novo nucleoside synthesis pathways, and are also necessary for the uptake of cytotoxic nucleosides used for cancer and viral chemotherapies. Multiple alternatively spliced variants, encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]
