Functional and Molecular Single-Cell Analyses Implicate PRDM14 in the Initiation of a Novel B-1 Cell Malignancy - Single Cell RNA sequencing experiments


ABSTRACT: Description: Molecular mechanisms underlying high-risk subtypes of leukemia remain elusive. PR domain-containing 14 (Prdm14) is a potent oncogene implicated in the initiation of many cancers, including leukemia. Here, we interrogate the heterogeneity of Prdm14-expressing cell types in a mouse model of T-cell acute lymphoblastic leukemia (T-ALL). We identified an abnormal B-1 cell-like population in pre-leukemic bone marrow. B-1 cells are a self-renewing population of unconventional B cells established during embryonic development. This dataset contains single-cell transcriptomic profiling of four samples. Cells from R26PR;Mx1-cre mice were sorted on GFP expression (“GFP+” and “GFP-” samples) or on a pro-B-1-like immunophenotype of CD11b- CD19+ CD127+ Sca-1+ (“Pre-leukemia” sample). As a control, immunophenotype-matched cells from R26PR mice were analyzed by scRNA-seq after sorting on CD11b- CD19+ CD127+ Sca-1+ (“Control” sample) (Supplemental Figure 2). Accordingly, we conducted scRNA-seq of four total samples: “GFP+”, “GFP-“, “Pre-leukemia”, and “Control”. The GFP+ and GFP- samples provide the cellular context to the bone marrow samples.
