Abstrakt: Background: Acute myeloid leukemia (AML) is a prevalent hematologic malignancy characterized by a steady rise in morbidity and mortality rates over time. The upregulation of methyltransferase-like 14 (METTL14) expression in AML has been identified; however, its specific contributions to AML progression and underlying molecular mechanisms have yet to be elucidated.
Method: METTL14-bound mRNAs were predicted using bioinformatics methods, analyzed, and screened to identify T-complex protein 1 (TCP1). The regulatory impact of METTL14 on TCP1 was observed. TCP1 expression in AML clinical samples was assessed using quantitative real-time PCR and western blot analysis. The involvement of TCP1 in AML malignant progression was assessed through in vitro and in vivo functional assays. The String database was utilized for predicting proteins that interact with TCP1, while western blot assays and immunoprecipitation were employed to validate the associated signaling pathways.
Results: METTL14 overexpression upregulates TCP1 expression in AML cells. AML patients exhibit high levels of TCP1 expression. Elevated TCP1 levels in HL60 and U937 cells in vitro lead to increased proliferation, migration, invasion, and inhibition of apoptosis, while in vivo, it accelerates AML proliferation and tumorigenesis. Mechanistically, METTL14 modulates AML progression by influencing TCP1 transcript stability via m6A methylation, thereby regulating TCP1 expression. Additionally, PPP2R2C potentially serves as a crucial functional target of TCP1 implicated in the malignant progression of AML.
Conclusion: Upregulation of TCP1 expression in AML through METTL14-mediated m6A modification accelerates the malignant progression of the disease. Therefore, targeting the m6A modification of TCP1 could be a potential therapeutic strategy to enhance the treatment of AML.
