In two additional studies conducted by the same research group, H3K27me3 levels were found to be significantly enriched at promoter sites of different genes, like retinoid acid receptor β2 (RARbeta2), estrogen receptor a (ERa), progesterone receptor (PGR), and repulsive guidance molecule A (RGMA) in prostate peritumoral (PPT) and/or PCa tissues [61,62]. This evidence concerns the gene RGMA and posterior cortical atrophy.
