Finally, western blotting, qPCR, and co‐immunoprecipitation results showed that NCoA6 interacted with HDAC1 and that NCoA6 expression was negatively correlated with F‐box and WD repeat domain‐containing 7 (FBW7) and caudal‐related homeobox transcription factor 2 (CDX2) expression in pancreatic cancer. This evidence concerns the gene CDX2 and pancreatic neoplasm.
