A bioinformatical analysis of the Ovarian TCGA dataset showed a clear-cut inverse correlation between the degree of methylation at the probe closest to the transcription start site and GBGT1 mRNA expression levels within the TCGA primary ovarian cancers, although the degree of GBGT1 methylation varied considerably among samples (ranging from nearly unmethylated to hypermethylated) and levels of GBGT1 methylation were also detected in adjacent normal ovarian tissue. This evidence concerns the gene GBGT1 and ovarian carcinoma.
