Principal component analysis (PCA) carried out to explore the relationships between H3K27 levels and clinicopathological parameters. H3K27me3 level was evaluated by PCA analysis. H3K27me3 levels on ER alpha, RAR beta 2, RGMA and PGR genes correlated positively with PSA level (PSA), clinical stage (patho) and Gleason score (Gleason).
