B4GALT1 and chronic myelogenous leukemia, BCR-ABL1 positive: To confirm that miR-124-3p targets the 3‘UTR region of B4GALT1 in CML cells, HEK293 cells were co-transduced with miR-124-3p expression or control vector along with either the full-length 3‘UTR of B4GALT1(Luci-B4GALT1) or mutated Luci-B4GALT1 reporter vectors bearing deletions of the 3‘UTR target regions (△Luci-B4GALT1) (Fig. 7b).
