Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a human oncoprotein overexpressed in head and neck squamous cell carcinoma and in colon cancer (Junttila and Westermarck, 2007; Junttila et al, 2007; Mumby, 2007). This evidence concerns the gene CIP2A and head and neck squamous cell carcinoma.
