Abstract
Frequent allelic imbalances including loss of heterozygosity (LOH) and microsatellite instability (MSI) on the short arm of chromosome 3 (3p) have been found in several types of human cancer. This study was designed to identify the tumor suppressor locus (or loci) on 3p associated with tongue squamous cell carcinoma (SCC). Among 16 patients with tongue SCC tested, 7 (44%) of 16 informative cases showed LOH at one or more loci. Deletion mapping of these 16 tumors revealed two discrete, commonly deleted regions on the chromosome arm. Our data support the notion that tumor suppressor gene(s) contributing to the progression of tongue squamous cell carcinoma reside on 3p24 and 3p25.
