Abstract

The aim of this study was to examine the role of Hh-Gli signaling in oral and oropharyngeal squamous cell carcinoma (SCC). The role of this signaling pathway in SCC formation has not yet been elucidated. Sixty-four tissue and blood samples were collected from 60 SCC patients, all tobacco and alcohol users. Additional 6 buccal mucosa tissue samples were collected from non-smokers and non-drinkers as control tissue. Hedgehog-Gli pathway components were associated with clinical and pathological features. Broders' grade and N stage were associated with higher Ptch1 and lower Gli1 expression. Tumor stage was negatively associated with Smo expression, and tumor size was positively associated with p16 expression. Ptch1 and Shh were frequently detected in the surrounding stroma. Ptch1 was found to be correlated with p16 expression, as well as with survivin expression. The signaling pathway is activated in SCC and inducible in vitro by Shh protein.
