Abstract
AIM: To further refine the region harboring the metastasis suppressor genes in the human chromosome 8p21.1-23.1, and to pave the way for finding and cloning novel metastasis suppressor genes.
METHODS: The STS primer sequences were found according to the National Center for Biotechnology Information Database (NCBI). C5F genomic DNA and A9/neo8 genomic DNA were used as negative and positive controls for chromosome 8 amplification, respectively. Genomic DNA was isolated and quantified from cultured hybrid clones. A9/C5F-1 and A9/C5F-2 microcell hybrid clones were used as metastasis-unsuppressed groups, while A9/C5F-4, A9/C5F-8 and A9/C5F-10 clones were used as metastasis-suppressed groups. STS-PCR products were separated by electrophoresis.
RESULTS: STS markers were preserved in metastasis-suppressed microcell hybrid clones (A9/C5F-4, A9/C5F-8 and A9/C5F-10), such as D8S552 (12786562-12786681), D8S1733(22576582-22576836), D8S1734 (22851217-22851336), D8S254(16652480-16652550) and D8S1973 (28681110-28681363) on human chromosome 8p21.1-23.1. In contrast, STS markers were lost in metastasis-unsuppressed clones (A9/C5F-1 and A9/C5F-2) in this region.
CONCLUSION: The metastasis suppressor genes may be located within the interval between D8S542 and D8S1973 on human chromosome 8p21.1-23.1.
