HNRNPC and head and neck squamous cell carcinoma: <h4>Background</h4>N6-methyladenosine (m6A) RNA modification is crucial for tumor development and progression; however, which m6A regulators play a pivotal role in head and neck squamous cell carcinoma (HNSCC) remains ambiguous.<h4>Methods</h4>Utilizing the Cancer Genome Atlas (TCGA) database, the expression levels of m6A regulators in HNSCC were examined, which led to the identification of heterogeneous nuclear ribonucleoprotein C (<i>HNRNPC</i>) as a key gene.
