  8. Human cell cycle and apoptosis regulator 2 (DBC1) regulates transcriptional elongation factor ELL stability involving HDAC3, p300, and Siah1. DBC1 competes with histone deacetylase 3 (HDAC3) for the same binding sites on ELL and thus increases its acetylation and stability. Knockdown of DBC1 reduces ELL levels and expression of a significant number of genes, including those involved in glucose metabolism.
    Title: DBC1, p300, HDAC3, and Siah1 coordinately regulate ELL stability and function for expression of its target genes.
  9. Because DBC1 maintains p53 stability in the nucleus, where p53 exerts its tumor-suppressive transcriptional function, replacement of DBC1 functionality in DBC1-deleted tumors might enhance p53 function and chemosensitivity for therapeutic benefit.

  10. DBC1 is required for LEF1/beta-catenin complex formation on the MACC1 enhancer and for long-distance enhancer-promoter interaction of the MACC1 locus. DBC1 overexpression further increased MACC1 expression in colonospheres and promoted sphere-forming abilities of colon cancer cells and drug resistance of colonospheres.

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.
