Upper panel: qPCR analysis of CDX2-negative HT29 cells treated with increasing concentrations of the DNMTi decitabine (1.25 μM, 2.5 μM, 5 μM, 10 μM) for 48 h and increasing concentrations of the HDAC4/5i LMK-235 (5 nM, 10 nM, 20 nM, 40 nM, 80 nM). Data were normalized to the HMBS housekeeping gene and are shown as n-fold regulation compared with DMSO-treated cells. MWU: ***p < 0.001, (n = 4). Lower panel: CDX2 Western blot analysis of the three highest concentrations for both compounds of HT29 cells treated as above. Total protein is shown as a loading control. Percentage indicates amount of protein normalized to respective DMSO controls
