Using a newly developed PCR-based technique called methylated CpG island amplification, we have identified several DNA fragments that are aberrantly methylated in a colon cancer cell line. One of the fragments, termed MINT31, mapped to human chromosome 17q21, where frequent loss of heterozygosity is detected in various human tumors. By characterizing the(More)
CpG island methylation has been linked to tumor suppressor gene inactivation in neoplasia and may serve as a useful marker to clone novel cancer-related genes. We have developed a novel PCR-based method, methylated CpG island amplification (MCA), which is useful for both methylation analysis and cloning differentially methylated genes. Using restriction(More)
