The gene for Cyclin D1 ( CCND1 ) lies within chromosomal region 11q13 and codes for a cell cycle regulator essential for G1 phase progression. This G1-cyclin is a putative protooncogene whose clonal rearrangement and/or amplification and mRNA overexpression occurs in several types of human neoplasias, including head and neck squamous cell carcinomas. Data from the literature suggest that amplification and overexpression of the CCND1 gene could lead to destabilisation of cell cycle control mechanisms and uncontrolled cell proliferation. We developed a differential PCR system for the determination of CCND1 gene amplification in head and neck squamous cell carcinomas. A 115 bp CCND1 fragment and a 150 bp γ-interferon fragment are amplified simultaneously in the same reaction tube under optimized conditions. Statistical analysis of amplification data obtained by differential PCR revealed excellent correlation with amplification data obtained by conventional Southern hybridization. |
