All three components are expressed in the two pairs of PCa cells, with the levels of EZH2 slightly higher in ARCaPE-shEPLIN and unchanged in C4-2B-TaxR, EED unchanged in ARCaPE-shEPLIN and higher in C4-2B-TaxR, SUZ12 higher in ARCaPE-shEPLIN and unchanged in C4-2B-TaxR. This evidence concerns the gene SUZ12 and posterior cortical atrophy.
