In recent years, there has been increasing interest in studying the role of epigenetic modifications in tumor invasion and metastasis (Huo & Zhang, 2021; Yankova & Blackaby, 2021; Zhang & Song, 2021). One of the most common modifications found in mRNA is N6-methyladenine (m6a), which regulates the expression of oncogenes and tumor suppressor genes through methylation transferase proteins. This process can promote tumor occurrence, invasion, and progression (Wu & Sang, 2018).
