Differentially expressed genes in hematopoietic stem cells after loss of Mettl3

Project description:Hematopoietic stem cells (HSCs) maintain balanced self-renewal and differentiation according to physiological demands, but how different facets of these functions are precisely regulated is not fully understood. N6-methyladenosine (m6A) mRNA methylation has emerged as an important mode of epitranscriptional gene expression regulation affecting many biological processes. We show that deleting the m6A methyltransferase, Mettl3, from the adult hematopoietic system led to an accumulation of HSCs in the bone marrow and marked reduction of HSC reconstitution potential due to a blockage of HSC differentiation. Interestingly, deleting Mettl3 from myeloid cells using Lysm-cre did not have any discernable impact on myeloid cell number or function. m6A sequencing on purified HSCs revealed 2,073 genes with significant m6A modification. In particular, Myc, a key regulator of HSC differentiation, was identified as a direct target of m6A in HSCs. Mettl3-deficient HSCs failed to up-regulate Myc expression upon stimulation to differentiate and enforced expression of Myc rescued differentiation defects of Mettl3-deficient HSCs. Our results thus revealed a key role of m6A in governing HSC differentiation by regulating Myc expression. This data includes RNA-Seq analysis to showing only minor gene expression changes in adult bone marrow murine hematopoietic stem cells 10 days after Mettl3 deletion by pIpC administration compared to pIpC treated controls.

Differentially expressed genes in Mettl3-deficient livers compared to control livers

Project description:Liver-specific deficiency of Mettl3 causes liver injury. By performing RNA sequencing (RNA-seq) analysis on the Mettl3-deficient versus control livers, we identified the potential target genes that were closely associated with the liver phenotype in liver-specific Mettl3 knockout mice. RNA-seq analysis revealed extensive metabolic reprogramming in Mettl3-deficient livers. These results demonstrated that Mettl3 coordinates metabolic homeostasis and functional maturation during postnatal liver development.

Multi-omics analysis of hematopoietic progenitors in the fetal liver of Mettl3 deficient mice

Project description:N6-methyladenosine (m6A) is the most abundant RNA modification, but little is known about its role in mammalian hematopoietic development. Conditional deletion of the m6A writer METTL3 in murine fetal liver results in hematopoietic failure and perinatal lethality. Loss of METTL3 and m6A activates an aberrant innate immune response, mediated by the formation of endogenous double-stranded RNAs (dsRNAs). The aberrantly formed dsRNAs are long, highly m6A modified in their native state, characterized by low folding energies and predominantly protein-coding. We identified coinciding activation of innate immune pattern recognition receptor pathways normally tasked with the detection of foreign dsRNAs. Our results suggest that m6A modification protects against endogenous dsRNA formation and a deleterious innate immune response during mammalian hematopoietic development.
