Abstract

The role of two important tumour suppressor genes, p16 and p53, was evaluated in cartilaginous tumour tissues. Genomic DNA from 22 chondrosarcomas, 5 benign chondroid tumours, 1 sample of reactive proliferative cartilage and 2 samples of normal cartilage were analysed using polymerase chain reaction, single strand conformational polymorphism, DNA sequencing and methylation-specific polymerase chain reaction. The p16 gene was found to be partly methylated in 5 high-grade chondrosarcomas and homozygously deleted in 1 chondrosarcoma. Moreover, a polymorphism was detected in 3 malignant tumours, but not in benign tumours or normal cartilage. Analysis of the p53 gene revealed an unchanged structure in all samples. These findings show a role for p16, but not p53, in chondrosarcoma. (C) 2000 Wiley-Liss, Inc.
