  • Title: Loss of heterozygosity at chromosomal regions 3p and 13q in non-small-cell carcinoma of the lung represents low-frequency events.
    Author: Becker D, Sahin AA.
    Journal: Genomics; 1989 Jan; 4(1):97-100. PubMed ID: 2536637.
    Abstract:
    It was recently reported that loss of heterozygosity occurred at the chromosomal region 3p in small-cell as well as in non-small-cell carcinoma of the lung. A recent report also indicated genetic changes involving sequences on chromosomes 13q and 17p in small-cell and in non-small-cell carcinomas. In the present study normal and tumor DNAs representing mostly adeno-and squamous cell carcinomas of the lung were examined for loss of heterozygosity on chromosomes 3p, 13q, 11p, and 1p. With the exception of two non-small-cell carcinomas which demonstrated loss of alleles on chromosome 3p and one small-cell carcinoma which demonstrated loss of heterozygosity at chromosome 3p as well as at 13q, evidence for loss of alleles on chromosomes 3p, 13q, 11p, and 1p could not be obtained in greater than 75% of the non-small-cell carcinoma DNAs tested. Given this result it appears unlikely that a recessive gene is located on either chromosome 3p or 13q in the majority of non-small-cell carcinomas of the lung.
