Abstract excerpt
PCR and direct DNA sequencing methods were used to analyse the prevalence of mutations in exon 2 of the p21waf1 gene in 14 oral squamous cell carcinomas (OSCCs) and 8 non-malignant oral mucosal lesions from Sudanese toombak dippers. For comparison, OSCCs (14 from the Sudan, 16 from Norway, 11 from Sweden, 21 from the USA and 14 from the UK) and non-malignant oral mucosal lesions (3 from the Sudan) from...
