ABSTRACT: Background
Abnormal spindle-like microcephaly (ASPM) has been proved to participate in tumor progression. However, the underlying mechanism of ASPM in liver hepatocellular carcinoma (LIHC) remains elusive.Methods
The mRNA and protein expression were determined using Western blot and qRT-PCR, and the capacities of cells proliferation, migration, and invasion were evaluated by CCK-8, colony formation, wound healing, and transwell. MeRIP was performed to validate the interaction between ASPM and methyltransferase-like 3 (METTL3).Results
Herein, we found that ASPM was significantly upregulated in LIHC, and the high expression of ASPM was associated with poor LIHC prognosis. Furthermore, ASPM knockdown could suppress LIHC cells proliferation, migration, and invasion, while ASPM overexpression exerted reverse effect. Mechanistically, we revealed that the N6-methyladenosine (m6A) modification of ASPM mRNA mediated by METTL3 promoted its expression in LIHC. More importantly, silencing METTL3 suppressed LIHC cells proliferation, migration, and invasion, which could be retained by ASPM overexpression.Conclusion
Collectively, our findings suggested that METTL3/ASPM axis could serve as a novel promising therapeutic candidate for LIHC.
