LncRNA SATB2-AS1 enhances the transcription of SATB2 by binding to growth arrest and DNA damage-inducible protein GADD45 alpha (GADD45A) and WD repeat-containing protein 5 (WDR5), which in turn inhibits the metastasis of colorectal cancer [20]. The gene discussed is GADD45A; the disease is colorectal cancer.
