scRNA-seq of control and eIF6-overexpressing MLL-AF9 leukemia stem cells

Despite the advanced understanding of disease mechanisms, the current therapeutic regimens fail to cure most patients with acute myeloid leukemia (AML). In the present study, we address the role of protein synthesis control in leukemia function and leukemia propagation. Using a transgenic eIF6 mouse strain that permits inducible and graded regulation of ribosomal subunit joining, we have generated a murine model of MLL-AF9 acute myeloid leukemia where the expression of transgenic eIF6 is doxycycline-inducible. Using this model system, we have performed scRNA-seq expression analysis to study the impact of eIF6 overexpression on leukemia cell function. scRNA-seq was performed using the 10x Chromium Next GEM Single Cell 3' platform. BM cells were harvested from leukemia-engrafted mice that were administered doxycycline for six days and viable GFP+ leukemia cells were sorted into PBS containing 0.05 % BSA following the manusfacturer's protocol. 5 samples: 2 control and 3 eIF6 overexpression.
