Squamous cell carcinoma (SCC) of the pharyngeal and oral cavity account for nearly 8,000 deaths a year nationally, with South Carolina leading the way in oral cancer mortality. The IGF system has surfaced as a target for cancer therapeutics in a number of cancers as individuals with the highest serum levels of IGF-1 have been found to exhibit the highest risk of breast and prostate cancer. Preliminary evidence has established that the squamous cell carcinoma cell line SCC-09 secretes insulin-like growth factor binding proteins (IGFBPs) 2, 3, and 5 and expresses the IGF-1 receptor in high number. Because hypoxia inducible factor 1 alpha (HIF-1α) has previously been shown to be a head and neck cancer biomarker, we are examining the role of IGF-1 and hypoxia on the expression of HIF-1a and the secretion of vascular endothelial growth factor (VEGF) in SCC-09 cells.
