Implication

Preclinical study demonstrates that m6A RNA modification stabilizes SLC7A11 to suppress ferroptosis in hepatoblastoma, suggesting a novel therapeutic vulnerability.

Key Points

To determine the biological role and molecular mechanisms of SLC7A11-mediated ferroptosis resistance in hepatoblastoma.
Quantified SLC7A11 levels in hepatoblastoma cell lines and evaluated cellular proliferation, colony formation, and lipid peroxidation markers (ROS, MDA, 4-HNE, and GSH/GSSG ratio).
Tested in vivo tumor growth using subcutaneous mouse xenograft models under SLC7A11 modulation.
Identified post-transcriptional m6A regulators using MeRIP-qPCR, dual-luciferase reporter, RNA pulldown, RNA immunoprecipitation, and RACE-PAT assays.
SLC7A11 was markedly upregulated in hepatoblastoma, which stimulated cell proliferation in vitro and in vivo while suppressing ferroptosis.
METTL3-mediated m6A deposition enhanced SLC7A11 mRNA stability, dependent on the reader protein IGF2BP1.
IGF2BP1 competitively bound PABPC1 to prevent recruitment of the BTG2/CCR4-NOT complex, thereby inhibiting SLC7A11 mRNA deadenylation and preserving its expression.
