In addition, ST6Gal1 knockdown in two additional BCP-ALLs, ICN13 and BM41 (Supplementary Table 1, Supplementary Figure 6B) did not provide results consistent with those in US7 cells, ruling out a universal regulation of these genes by ST6Gal1 expression in BCP-ALL. The gene discussed is ST6GAL1; the disease is acute lymphoblastic leukemia.
