SLAM-Seq analysis of Ythdf2-deficient pre-leukemic cells

Project description:The mRNA m6A reader YTHDF2 is overexpressed in a broad spectrum of human acute myeloid leukemias (AML). To study the role of YTHDF2 on mRNA decay rates in leukemia, c-Kit+ cells from foetal livers of Ythdf2fl/fl; Vav-iCre (Ythdf2CKO) and Ythdf2fl/fl (Ythdf2CTL) 14.5 dpc embryos were transduced with Meis1 and Hoxa9 oncogenes and serially re-plated to generate pre-leukemic cells. Medium with 4SU was used for pre-leukemic cells labelling for 12 hours and was later replaced with 4SU-free medium (time 0). Cells were collected immediately after medium change and at 1, 3 and 9 hours for library generation. RNA from Ythdf2CKO (n=3 biological replicates) and Ythdf2CTL (n=3 biological replicates) pre-leukemic cells were used for SLAM-seq library generation.

Microarray data from YTHDF2-deficient pre-leukemic cells and control pre-leukemic cells

Project description:YTHDF2 is overexpressed in a broad spectrum of human acute myeloid leukemias (AML). To study the role of YTHDF2 in leukemia, c-Kit+ cells from foetal livers of Ythdf2fl/fl;Vav-iCre (Ythdf2CKO) and Ythdf2fl/fl (Ythdf2CTL) 14.5 dpc embryos were transduced with Meis1 and Hoxa9 oncogenes and serially re-plated to generate pre-leukemic cells. Total RNA from Ythdf2CKO (n=5) and Ythdf2CTL (n=5) pre-leukemic cells were used for Affymetrix global gene expression analysis.

RIBO-seq analysis of YTHDF2-deficient pre-leukemic cells and control pre-leukemic cells

Project description:YTHDF2 is overexpressed in a broad spectrum of human acute myeloid leukemias (AML). To study the role of YTHDF2 on translation regulation in leukemia, c-Kit+ cells from foetal livers of Ythdf2fl/fl; Vav-iCre (Ythdf2CKO) and Ythdf2fl/fl (Ythdf2CTL) 14.5 dpc embryos were transduced with Meis1 and Hoxa9 oncogenes and serially re-plated to generate pre-leukemic cells. RIBO-seq libraries were then prepared from Ythdf2CKO (n=3) and Ythdf2CTL (n=3) pre-leukemic cells.

Microarray profiling of YTHDF2 deficient mouse oocytes

Project description:To study the role of the protein YTHDF2 during female gametogenesis, its gene was conditionally deleted in oocytes. Total RNA samples from YTHDF2 deficient GV and MII oocytes (and control oocytes) were subjected to array profiling.

Bacterial translocation is required for pre-leukemic myeloproliferation in Tet2 deficient mice

Project description:Ten-Eleven-translocation (Tet2) encodes an epigenetic modifier enzyme and is mutated somatically during age-associated clonal hematopoiesis of indeterminate potential (CHIP) as well as in myeloid malignancies 1-7. Tet2 deficiency leads to increased hematopoietic stem cell (HSC) renewal in human 7 and mouse 8. However, the development of myeloproliferation and myeloid malignancies occurs at late age, and only occasionally in humans 2,6,7,9 and in 50-75% of Tet2 deficient animals 8,10,11, suggesting that undefined triggers are required for pre-leukemic myeloid expansion. Our studies reveal that Tet2 deficient mice can exhibit high levels of plasma IL-6, systemic dissemination of indigenous gut bacteria and increased intestinal permeability that correlate with the development of a pre-leukemic myeloproliferative phenotype. Increased intestinal permeability was linked to a large number of transcriptional changes in the jejunum, especially among genes involved in defense response to bacterium and intestinal barrier function. Strikingly, antibiotic treatment reduced plasma IL-6 levels and both, prevented early myeloid expansion and reversed the pre-leukemic myeloproliferative phenotype in Tet2-/- mice. In summary, we show that Tet2 deficiency promotes intestinal bacterial translocation and subsequent systemic inflammation, and that gut-derived microbial signals are required for the development of pre-leukemic myeloproliferation in a Tet2-deficient host. Our studies suggest that controlling bacterial translocation and bacteria-associated systemic inflammation could decrease the risk of myeloid malignancies significantly in individuals with somatic Tet2 mutations.
