Loss of heterozygosity on chromosome 9 has been reported in a variety of human cancers. The cyclin-dependent kinase inhibitor p16 gene, mapped on chromosome 9p21, is presumed to be the tumor-suppressor gene localized in this chromosome. The aim of our study was to determine, in 26 Barrett's adenocar

Abstract
To elucidate the involvement of abnormalities of the MTS1/p16 and MTS2/p15 genes located at chromosomal region 9p21 in human lung cancers, we analyzed DNA from 30 primary lung cancers and detected loss of heterozygosity at the 9p21‐p23 region in 15 tumors. Single‐strand‐conformation‐polymorphism analysis of polymerase‐chain‐reaction products from the MTS1 and MTS2 genes and determination of the nucleotide sequences revealed the presence of a mutated MTS1 gene in 2 of 15 tumors with a loss of corresponding loci. No mutations of the MTS2 gene were found. These results suggested that mutations of the MTS1 gene are associated with at least some human lung cancers. © 1995 Wiley‐Liss, Inc.

Cyclin-dependent kinillre-4 inhibitor genes (INK4) regulate the cell cycle and are candidate tumor-suppressor genes. To determine if alterations in the coding regions of the p18 and p l 9 genes, which are novel members of the INK4 family and if they correlate with the development of human cancer, 10
Deletions involving the chromosome 9p21 region have been reported as frequent events in non-small cell lung cancer (NSCLC). To investigate potential tumor-suppressor gene (TSG) loci within the 9p21 region, which also harbors the candidate TSG locus CDKN2a, we studied 32 cases of primary NSCLC for lo
## Abstract Loss of heterozygosity (LOH) at chromosome 3p21 is frequent in cervical cancers. The candidate tumor suppressor gene, __RASSF1A__ located at 3p21.3, is found to be inactivated in several major human cancers, implicating its significance in carcinogenesis. We aimed to investigate the sta
To date, several tumor-suppressor genes responsible for the tumorigenesis of colorectal cancer have been identified. However, studies of loss of heterozygosity (LOH) have suggested several chromosomal regions which may contain additional tumor-suppressor genes for colorectal cancer. To determine the
