Project description:To identify potential mRNA targets of FTO whose m6A levels are influenced in acute myeloid leukemia (AML) cells, we conducted m6A-seq for mRNA isolated from MA9.3ITD cells with and without knockdown of FTO
Project description:To identify the potential targets genes of FTO in acute myeloid leukemia (AML), we peroformed RNA-seq of NB4 cells with or without FTO knockdown based on Illumina Hiseq system.
Project description:To identify potential mRNA targets of FTO whose m6A levels are affected by FTO in acute myeloid leukemia (AML) cells, we conducted m6A-seq for messenger RNAs isolated from AML cells with and without forced expression of FTO.
Project description:FTO, an N6-methyladenosine demethylase, has emerged as a promising target for the treatment of specific acute myeloid leukemia (AML) subtypes. Here, we investigate the antiproliferative effects of the FTO inhibitor FB23-2 in leukemia. We demonstrate that FB23-2 potently inhibits proliferation across both AML and CML cell lines, irrespective of their responsiveness to FTO depletion. Interestingly, FB23-2 induces cell cycle arrest without a concurrent increase in m6A levels, suggesting an alternative mechanism of action.
Project description:The fat mass and obesity-associated protein (FTO), an RNA m6A eraser, has been identified as a critical oncogenic factor in acute myeloid leukemia (AML). We presented the development of an FTO degrader(FP54) that selectively degrades FTO in AML cells, demonstrating superior efficacy both in vitro and in vivo. Mechanistically, FTO degradation increases m6A modifications on ribosome biogenesis related mRNAs and thus promotes YTHDF2-mediated degradation. This process impairs ribosome biogenesis and translation process, ultimately inhibiting AML progression.
