Polycomb complexes in normal and malignant hematopoiesis

Abstract excerpt

Epigenetic mechanisms are crucial for sustaining cell type-specific transcription programs. Among the distinct factors, Polycomb group (PcG) proteins are major negative regulators of gene expression in mammals. These proteins play key roles in regulating the proliferation, self-renewal, and differentiation of stem cells. During hematopoietic differentiation, many PcG proteins are fundamental for proper lineage...
