Abstract

This study is designed to verify the immunohistochemical expression of ²2-adrenergic receptor (²2-AR) in the malignant cells of fresh tumor specimens of oral squamous cell carcinomas (OSCC) and in the oral epithelium adjacent to the tumor, with the aim to compare and confirm the immunohistochemical expression previously verified in paraffin-embedded samples of OSCC. Fresh OSCC samples (n=15) frozen at - 20 °C will be analyzed for the ²2-AR expression in the epithelial cells of the oral mucosa and neoplastic cells of the OSCC. Microscopic fields of the invasion tumor front will be captured with a camera integrated to light microcopy at 400 X magnification. The ²2-AR immunohistochemical expression by neoplastic cell of each microscopic field will be analyzed and compared to images of OSCC obtained from paraffin-embedded samples previously investigated for Bravo-Calderón et al (2011).
