title: Hot spots for molecular genetic alterations in lung cancer.
abstract: Lung cancers are a heterogeneous group of tumors broadly classified as small cell or non-small cell lung cancers. In each case, numerous DNA mutations precede tumor formation, resulting in the activation of growth stimulatory genes and the loss of tumor suppressor genes. The known cellular functions of the tumor suppressor genes most commonly affected in lung cancer are reviewed herein, including the retinoblastoma (Rb) gene on chromosome 13q14, the p53 gene on 17p13, and the cyclin-dependent kinase inhibitor (CDKN2) gene on 9p21. The chromosomal locations for other potential tumor suppressor genes are on chromosomes 3p, 9p, and 11p. Candidate genes in these regions include the von Hippel-Lindau (VHL) gene at 3p25, the ubiquitin-activating enzyme homologue (UBE1L at 3p21, the genes for the dinucleoside polyphosphate hydrolase FHIT and receptor protein-tyrosine phosphatase gamma PTPRG at 3p14.2, the genes for tropomyosin beta (TM1) and a talin homologue (talin) at 9p21, and the H-ras gene at 11p15.
