Abstract:
PURPOSE:Genomic stability is maintained by error-free DNA replication, repair, and recombination. To determine if repair genes contribute to genomic instability, we used a newly established cell line RCC-AJR (from clear-cell renal cell carcinoma) to examine hMSH2 (a mismatch-repair gene) and the gene encoding DNA beta polymerase (polbeta; a known contributor to base-excision repair). METHODS:Coding sequences of hMSH2 and polbeta were amplified by the polymerase chain reaction (PCR) using RNA from RCC-AJR cells and matched normal kidney (NK) cells from the same patient. Nucleotide sequences of the PCR products were determined by the dideoxy-DNA method and direct sequencing. Expressions of repair genes were assayed by Western blotting. Microsatellite stability in RCC-AJR cells was assayed by alteration in (CA)n repeats. RESULTS:In the RCC-AJR cells, we detected (a) a deletion of 1476 bp encoding 492 amino acids of hMSH2 cDNA, (b) an 87-bp deletion in the polbeta coding sequence, (c) truncated forms of hMSH2 and polbeta proteins, and (d) microsatellite instability. CONCLUSIONS:This study provides evidence of alterations in hMSH2 and polbeta in the homogeneous cell population of an RCC-AJR tumor culture. The data indicate that repair genes may help preserve genomic stability in this cell line. We believe that this new primary RCC-AJR cell line will prove a useful model for investigating the cascade of genetic events in renal cells that leads to renal carcinogenesis.
