ATP6V1C1 and lip and oral cavity carcinoma: The function of Atp6v1c1 in metastasis is poorly defined but studies have shown that Atp6v1c1 is overexpressed in oral cancer patients and encodes an element of vacuolar ATPase (V-ATPase), a multi-subunit enzyme that accelerates the process of acidification in the intracellular components of eukaryotic cells31.
