With regard to both HDAC5 as well as HDAC7 expression, we found significant differences between D3 vs. M3 tumours for only one of the two probes that had been used (HDAC5 probe 1 p = 0.90, HDAC5 probe 2 p = 0.004, HDAC7 probe 1 p = 0.30, HDAC7 probe 2 p = 0.02). This evidence concerns the gene HDAC5 and neoplasm.
