Single-cell multi-omic profiling reveals dynamic gene expression networks across developing B cells, highlighting key developmental nodes linked to leukemic transformation.

Key Points

To delineate the dynamic gene expression networks that orchestrate B cell lineage differentiation and identify developmental nodes linked to B cell leukemia subtypes.
Analyzed developing B cells using single-cell transcriptomics and proteomics to map differentially expressed gene networks.
Conducted pseudotime trajectory analysis to trace the kinetic patterns of transcription factors, cytokines, chemokines, and their receptors.
Identified distinct transcriptional programs that resolve the pre-B cell expansion window into pre-BCR-dependent and pre-BCR-independent proliferative phases.
Demonstrated that the pre-BCR-dependent stage is defined by reciprocal shifts in the expression of the transcription factor EBF1 and the RNA-binding protein YBX3.
Mapped developmental expression kinetics across regulatory modalities to characterize transitional nodes associated with malignant transformation in B cell leukemia.
