Since Taz treatment alone did not appreciably alter EZH2 and EZH2T367p levels, these results support the dominant effect of B32B3 over Taz and point to DCAF1-mediated EZH2T367p as a key determinant for H3K27me3-induced oncogenic gene silencing in colon cancer. Here, DCAF1 is linked to colonic neoplasm.
