Mutation analysis of the Bcl 10 gene in hepatocellular carcinoma.
The Bcl 10 gene was recently discovered to be involved in the pathogenesis of lymphoma of mucosa-associated lymphoid tissue and several types of tumorous cell lines. We examined the mutation of Bcl 10 gene in 31 hepatocellular carcinomas along with their corresponding non-tumorous tissues by single strand conformation polymorphism (SSCP) and direct sequencing. The results showed that 11.3% chromosomes had codon 5 GCA to TCA mutation, 4.8% chromosomes had codon 8 CTC to CTG mutation, and 12.9% chromosomes had codon 213 GGA to GAA mutation. These mutations were found not only in the hepatoma tissues but also in paired non-cancerous tissues and the normal population. We suggest that these three changes are polymorphisms, and there is no relationship with the development of hepatocellular carcinoma.
