Dynamics of m6A RNA methylome during leukemogenesis reveals a role of PRMT6-MFSD2A signaling axis in maintaining AML stem cells.[Chip-seq]

ABSTRACT: We delineate a comprehensive m6A landscape during acute myeloid leukemia (AML) development, and identify PRMT6, regulated by IGF2BP2, acting as a key for leukemia stem cell maintenance by restraining MFSD2A expression and docosahexaenoic acid level.

Dynamics of m6A RNA methylome during leukemogenesis reveals a role of IGF2BP2-PRMT6-MFSD2A signaling axis in maintaining AML stem cells [Prmt6 RNA-seq]

Project description:Our data reveal that RNA m6A displays a sharp transition during leukemogenesis and involves in acquiring stem cell properties of leukemia stem cells (LSCs). We find that m6A reader IGF2BP2 and protein arginine methyltransferase PRMT6 play key roles in the acquisition of LSCs properties. Genetical deletion and pharmacological inhibition of PRMT6 delayed AML development. Mechanistically, IGF2BP2 regulates PRMT6 expression by stabilizing its mRNA in an m6A-dependent manner. PRMT6 further suppresses the expression of lipid transporter MFSD2A by establishing inactive H3R2me2a in its promoter region. Loss of PRMT6 and IGF2BP2 upregulates the expression of MFSD2A that increases the uptake of docosahexaenoic acid. Collectively, our findings uncover a critical role of IGF2BP2-PRMT6-MFSD2A signaling axis in AML development, and provide a promising therapeutic strategy for targeting LSCs.

Impact of Major Facilitator Superfamily Domain containing 2a (Mfsd2a) mediated lipid transport on oligodendrocyte lineage development at single cell level.

Project description:Mfsd2a is involved in transport of essential fatty acids such as docosahexaenoic acid (DHA) from the periphery across blood brain barrier (BBB) into the brain parenchyma. Loss of Mfsd2a in humans leads to microcephaly and hypomyelination. The significance of lipid species transported by Mfsd2a on oligodendrocyte lineage development is not known. Using OPC specific deletion of Mfsd2a (2aOKO) in mice we found that OPC cell state, differentiation and oligodendrocytes maturation is disrupted resulting in hypomyelination compared to 2afl/fl controls. Single cell RNAsequencing analysis was performed on total oligodendrocyte population from postnatal mouse brain using Ribo-TRAP mouse lines that labels complete oligodendrocyte lineage with GFP fluorescence to understand the influence of Mfsd2a on oligodendrocyte development.
