Meta-analysis of ST6GalNAc1 expression in colon and breast cancer tissue versus normal tissue shows significant down-regulation in 6/8 datasets for primary colon cancer (Supplementary Table 7B), and in 4/8 datasets for primary breast cancer (Supplementary Table 7C), the opposite of what we see in PCa. The gene discussed is ST6GALNAC1; the disease is colonic neoplasm.
