In a panel of colon and duodenal cancer cell lines (Fig. 1D), RT-qPCR analyses revealed significantly increased constitutive mRNA expression of BAZ1A compared to a normal colonic epithelial cell line (CCD841), with the exception of SW480 cells, and IB revealed concordance at the protein level, using histone H3 and β-actin as loading controls. This evidence concerns the gene ACTB and duodenum cancer.
