Our analyses revealed lower abundance of METTL3 and FTO transcripts in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), breast invasive carcinoma (BRCA), lung adenocarcinoma (LUAD), and colon adenocarcinoma (COAD) compared to their matched normal tissues. This evidence concerns the gene METTL3 and invasive breast carcinoma.
