Loss of the putative tumor suppressor protein spinophilin is associated with poor prognosis in head and neck cancer.

The putative tumor suppressor protein spinophilin has been recently involved in the pathogenesis of lung, liver, and other types of cancer. Previous studies also indicate that a loss of spinophilin in combination with functional impairment of p53 drives tumor progression. To date, no data exist about the role of spinophilin in head and neck squamous cell carcinoma (HNSCC).
