Differential Expression of Potential Biomarkers of Oral Squamous Cell Carcinoma Development.

ABSTRACT: To evaluate molecular epithelial changes, we investigated whether a profile of survivin, cyclin dependent kinase inhibitor 2A (CDKN2A), epidermal growth factor receptor (EGFR), polo like kinase 1 (PLK1), p63, p40 (Δnp63 isoform), cyclin D1 (CCND1) and BCL2 apoptosis regulator (BCL2) proteins could predict malignant transformation. Different tissue segments (tumor adjacent epithelium; dysplasia and tumor) from a total of 109 patients were analyzed by immunohistochemistry. An increased expression of survivin (p < 0.001), PLK1 (p = 0.001), and p63 (p < 0.001) in parallel to reduced immunostaining of p40 (p < 0.001) and BCL2 (p = 0.029) was observed among the tissue segments analyzed. Our study revealed that survivin, PLK1, p63, p40 and BCL2 play a role in oral tumorigenesis and represent prom
