Study found lower organic solute transporter beta (OSTbeta) expression in colon cancer tissues compared with adjacent normal tissues and revealed the epigenetic mechanisms of it and proved that p300 controls OSTbeta expression through modulating H3K27Ac state at OSTbeta promoter region and hence causes low expression of OSTbeta in colorectal cancer.

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.
