Another study found that METTL14 overexpression inhibits papillary thyroid carcinoma (PTC) cell proliferation and migration/invasion by suppressing OIP5-AS1 expression and regulating the epidermal growth factor receptor (EGFR) and mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) pathways [24]. Here, EGFR is linked to thyroid gland papillary carcinoma.
