Abstract

A number of different candidate tumor suppressor genes involved in human breast cancer are presumed to be located on chromosome 17. To verify the relevance of chromosome 17 abnormalities in breast cancer cells, a normal human chromosome 17 was transferred by microcell fusion to R30 tumor cells derived from an infiltrating ductal mammary carcinoma. The tumorigenicity of the microcell hybrids in nude mice was examined. The tumor volume obtained with different clones was reduced by up to 94% of the value corresponding to the parental tumor cells. This effect was accompanied by a reduction of anchorage-independent growth, as well as cell growth rates on plastic plates. These effects were independent of the continued presence of a transferred 17q arm and could not be attributed to the action of the normal p53 gene. The results support the assumption that in addition to p53 a further tumor suppressor gene is located on 17p which is involved in breast cancer.
