The Mettl3 epitranscriptomic writer amplifies p53 stress responses.

Project description:The p53 transcription factor drives anti-proliferative gene expression programs in response to diverse stressors, including DNA damage and oncogenic signaling. Here, we seek to uncover new mechanisms through which p53 regulates gene expression using tandem affinity purification/mass spectrometry to identify p53-interacting proteins. This approach identified METTL3, an m6A RNA-methyltransferase complex (MTC) constituent, as a p53 interactor. We find that METTL3 promotes p53 protein stabilization and target gene expression in response to DNA damage and oncogenic signals, by both catalytic activity-dependent and independent mechanisms. METTL3 also enhances p53 tumor suppressor activity in in vivo mouse cancer models and human cancer cells. Notably, METTL3 only promotes tumor suppression in the context of intact p53. Analysis of human cancer genome data further supports the notion that the MTC reinforces p53 function in human cancer. Together, these studies reveal a fundamental role for METTL3 in amplifying p53 signaling in response to cellular stress.

METTL3 Inhibitors for Epitranscriptomic Modulation of Cellular Processes.

Project description:The methylase METTL3 is the writer enzyme of the N6 -methyladenosine (m6 A) modification of RNA. Using a structure-based drug discovery approach, we identified a METTL3 inhibitor with potency in a biochemical assay of 280 nM, while its enantiomer is 100 times less active. We observed a dose-dependent reduction in the m6 A methylation level of mRNA in several cell lines treated with the inhibitor already after 16 h of treatment, which lasted for at least 6 days. Importantly, the prolonged incubation (up to 6 days) with the METTL3 inhibitor did not alter levels of other RNA modifications (i. e., m1 A, m6 Am , m7 G), suggesting selectivity of the developed compound towards other RNA methyltransferases.

Differential gene expression analysis for BAL cells isolated from LysM Cre and Netrin1loxp/loxp LysM Cre mice after intratracheal LPS challenge

Project description:Purpose: The goal of this study is to compare NGS-derived transcriptome profiling (mRNA-seq) of expressed genes between LysM Cre and Netrin1loxp/loxp LysM Cre mice 3 days after intratracheal LPS challenge in order to explain the worsened outcomes and increased levels of inflammation we measure in the Netrin1loxp/loxp LysM Cre mice Methods: Three days after mice were treated with intratracheal injections of LPS, BAL cells were collected and then depleted for neutrophils using antibody-mediated depletion. The remaining cells were used for RNA isolation. mRNA profiles were generated by deep sequencing, in quadruplicate (one sample in the Netrin1loxp/loxp LysM Cre group was excluded as the sequence depth was only half compare to other 3 replicates), using paired-end 75-cycle sequencing on an Illumina NextSeq 550 System. Bases with quality scores < 20 and adapter sequences were removed from raw data with Cutadapt (v1.15), followed by alignment of clean RNA-seq reads to GRCm38 with STAR(v2.5.3a). Gene abundance was counted by HTseq-count uniquely-mapped reads number with default parameter using GencodeM15. Genes with > 5 reads in at least one sample were included for differential expression analysis by DESeq2 software.

Genome-wide analysis of mRNA expression alterations of sorted LysM-KI LSK cells versus control LSK cells

Project description:Microarrays were used to examine gene expression changes between bone marrow isolated haematopoeietic cell populations (LSK cells: Lin-Sca1+cKit+) populations of control and mutant (LysM-KI) mice. The LysM-KI mouse is a murine model which expresses an Idh1 (isocitrate dehydrogenase 1) mutation (Idh1-R132H) in cells of the myeloid lineage. Mutations in IDH1 (and IDH2) in humans are commonly found in cytogenetically normal acute myeloid leukemia as well as glioblastomas. The current study was initiated to understand how these mutations may affect leukemogenesis and myeloid cell development. Total RNA obtained from bone marrow sorted LSK cells of mutant LysM-KI and control individual mice.

METTL3 mediated m6A mRNA methylation regulates neutrophil activation through targeting TLR4 signaling (Ribosome-Seq)

Project description:To investigate the effect of METTL3 function in the regulation of neutrophil activation, we established neutrophil METTL3 knock out mice by crossing METTL3flox/flox mice with Lyzm-cre mice. We then performed gene expression profiling analysis using data obtained from Ribosome-seq of isolated neutrophil from METTL3f/f and METTL3f/f Lyzm-Cre mice .
