GSTP1, encoding the pi-class glutathione S-transferase, is commonly inactivated by somatic CpGisland hypermethylation in cancers of the prostate, liver, and breast. We report here thathypermethylation of CpG dinucleotides at the 5' transcriptional regulatory region was sufficient to inhibit GSTP1 transcription in MCF-7 breast cancer cells and that(More)
Hypermethylation of CpG island (CGI) sequences is a nearly universal somatic genome alteration in cancer. Rapid and sensitive detection of DNA hypermethylation would aid in cancer diagnosis and risk stratification. We present a novel technique, called COMPARE-MS, that can rapidly and quantitatively detect CGI hypermethylation with high sensitivity and(More)
Dynamic metabolomics studies can provide a systematic view of the metabolic trajectory during disease development and drug treatment and reveal the nature of biological processes at metabolic level. To extract important information in a systematic time dimension rather than at isolated time points, a weighted method based on the means and variations along(More)
