Abnormal expression of oncogenes or proto-oncogenes are frequently related with cancer development. The epidermal growth factor receptor (EGFR) gene has been found to be amplified and/ or expressed at high levels in various types of tumor cells including A431 human epidermoid carcinoma cells [1,2,3]. Although the over-production of EGFR protein generally correlates with an elevated level of its mRNA, it does not always accompany EGFR gene amplification [4,5].Therefore, to understand the abnormal nature of cancer growth, the analysis of their gene expression at the transcriptional level as well as the transcript level is required.
