Post-treatment circulating plasma BMP6 mRNA and H3K27 methylation levels discriminate metastatic prostate cancer from localized disease

Abstract

Background: We evaluated the utility of post-treatment plasma levels of the circulating bone-morphogenetic protein-6-specific mRNA (cBMP6 mRNA), cell-free DNA (cf-DNA), apoptotic nucleosomes and Histone H3 lysine 27 trimethylation (H3K27me3), in discriminating metastatic prostate cancer (PCa) from organ confined, locally controlled disease.
