Hereditary renal cell carcinoma in the rat associated with nonrandom loss of chromosomes 5 and 6.

Published

Journal Article

A spontaneous form of renal cell carcinoma occurs in rats that arises as the result of the inheritance of a mutation in a single autosomal gene. Cytogenetic analysis was performed on seven cell lines and four primary tumor cell preparations derived from this hereditary form of renal cell carcinoma. Banded karyotypes prepared from these seven lines exhibited loss and/or partial deletion of both chromosomes 5 and 6. Translocations involving chromosome 4, resulting in a net loss of genetic material located near the centromere (4q11), were observed in three of the cell lines. Monosomy, translocation, and breakage of chromosome 5 involving band 5q31 and monosomy and partial deletion of chromosome 6 involving band 6q22-q24 were independently observed in primary tumor cells from three of four tumors examined. Monosomy of chromosome 4 was observed in cells from a single tumor. The smallest region of deletion of chromosome 6 common to all the cell lines and tumor cells was 6q24, suggesting the presence of a tumor suppressor gene at this locus. These results indicate that loss of genes located on chromosomes 4, 5, and 6, possibly tumor suppressor gene(s), may be important for tumor development and/or progression in rat renal cell carcinoma and is consistent with the hypothesis that a gene locus on one of these chromosomes may be the site of the original predisposing mutation.
