The majority of cancer tissues displayed weak to moderate nuclear positivity, in a few cases combined with cytoplasmic immunoreactivity. Most renal and testicular cancers along with several lung and skin cancers were negative.
Moderate nuclear immunoreactivity was observed in most cancer tissues. Testicular cancers along with a few gliomas, skin, urothelial and pancreatic cancers were strongly stained. Most hepatocellular carcinomas, renal and endometrial cancers were weakly stained or negative.
GENE INFORMATION
Gene name
NR1H3 (HGNC Symbol)
Synonyms
LXR-a, RLD-1
Description
Nuclear receptor subfamily 1, group H, member 3 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene belongs to the NR1 subfamily of the nuclear receptor superfamily. The NR1 family members are key regulators of macrophage function, controlling transcriptional programs involved in lipid homeostasis and inflammation. This protein is highly expressed in visceral organs, including liver, kidney and intestine. It forms a heterodimer with retinoid X receptor (RXR), and regulates expression of target genes containing retinoid response elements. Studies in mice lacking this gene suggest that it may play an important role in the regulation of cholesterol homeostasis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]
