['Increased expression of fibroblast growth factors and their receptors (FGFRs) has recently been described in oral squamous cell carcinoma. In addition, we have previously described a molecular basis for an association between oral cancer and diabetes. The expression of FGFR-2 and FGFR-3 investigated in an experimental model of chemically induced carcinogenesis in normal and diabetic (type I) rats.', 'Tissue sections ranging from normal mucosa to moderately-differentiated oral squamous cell carcinoma were studied using monoclonal antibodies against FGFR-2 and FGFR-3 proteins.', 'A similar pattern of elevated FGFR-2 and FGFR-3 expression was observed in the initial stages of oncogenesis for both diabetic and non-diabetic animals. In the last stages of oral oncogenesis, the expression of both proteins remained relatively stable.'] Does diabetes influence oral oncogenesis through fibroblast growth factor receptors?
