CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: Specifically, we found that miR-362-5p was highly expressed in leukaemia cell lines, such as BV173, K562, Ball-1 and Jurkat, but it not in non-leukemia 293 T cells and normal CD34+ cells (Fig. 1a); and the highest level of miR-362-5p expression was found in CML cell lines (BV173 and K562, Fig. 1a).
