Observations on EGFR gene amplification and polymorphism in prostatic diseases.
This study was designed to determine the amplification and polymorphism of epidermal growth factor receptor (EGFR) gene in prostatic diseases like benign hypertrophy (BPH) and carcinoma (CaP). The EGFR gene was found to be amplified in grade IV BPH as compared to grade II BPH. Digestion of genomic DNA with MspI and HpaII revealed the presence of a 5kb band following southern blot analysis. This 5kb band was present in all the CaP cases and in one out of three BPH cases. It is possible that such a polymorphism is associated with the type or extent of tumor progression.
