GABRP and ovarian carcinoma: To address the mechanism of GABRP overexpression in metastatic ovarian cancer cells, we analyzed genome-wide DNA methylation profiling data and identified two GABRP promoter CpG sites at −1142 and −963 bp from the transcription start site that were hypomethylated in metastatic tissues from xenograft mice compared with those in the injected ovarian carcinoma cells.
