TET2-mediated mRNA demethylation regulates leukemia stem cell homing and self-renewal. Cell Stem Cell 2023; 30:1072-1090.e10. [PMID: 37541212 PMCID: PMC11166201 DOI: 10.1016/j.stem.2023.07.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 05/10/2023] [Accepted: 07/03/2023] [Indexed: 08/06/2023]
Abstract
TET2 is recurrently mutated in acute myeloid leukemia (AML) and its deficiency promotes leukemogenesis (driven by aggressive oncogenic mutations) and enhances leukemia stem cell (LSC) self-renewal. However, the underlying cellular/molecular mechanisms have yet to be fully understood. Here, we show that Tet2 deficiency significantly facilitates leukemogenesis in various AML models (mediated by aggressive or less aggressive mutations) through promoting homing of LSCs into bone marrow (BM) niche to increase their self-renewal/proliferation. TET2 deficiency in AML blast cells increases expression of Tetraspanin 13 (TSPAN13) and thereby activates the CXCR4/CXCL12 signaling, leading to increased homing/migration of LSCs into BM niche. Mechanistically, TET2 deficiency results in the accumulation of methyl-5-cytosine (m5C) modification in TSPAN13 mRNA; YBX1 specifically recognizes the m5C modification and increases the stability and expression of TSPAN13 transcripts. Collectively, our studies reveal the functional importance of TET2 in leukemogenesis, leukemic blast cell migration/homing, and LSC self-renewal as an mRNA m5C demethylase.

Abstract
Acute myeloid leukemia (AML) is one of the most common and fatal forms of hematopoietic malignancies. Here, we describe a mouse MLL-AF9_AML model to investigate AML. We have optimized the protocols for retrovirus infection, bone marrow transplantation (BMT), and leukemia monitoring to create a stable mouse model. In particular, we have used two rounds of BMT to enhance stability and efficiency. This model can be used to conduct drug administration and/or other interventions easily. For complete details on the use and execution of this protocol, please refer to Zhao et al. (2022). Optimized BMT accelerates full blast leukemia in recipient mice Step by step details of two rounds of BMT and tissue sample collection Protocols for monitoring AML pathogenesis after each BMT
Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
