Cyp27a1 is present in glial cells and is regulated in response to LXR activation, consistent with the role played by astrocytes in the control of cholesterol metabolism and homeostasis in the brain in physiological conditions

Depleted uranium affects both vitamin D active form and receptor expression and consequently could modulate the expression of cyp24a1 and vitamin D target genes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
