DUBR and acute myeloid leukemia: For assessing DUBR’s biological effect on AML, we explored the effect of DUBR knockdown by siRNA (target sequence: AGC​AGA​GAA​AAG​GAA​AGA​AAA​CT) on the colony-forming, proliferation and apoptosis assays of KG-1 and Molm-13 cells (The efficiency of DUBR siRNA in KG-1 and Molm-13 cells are shown in Supplementary Figure S1).
