Comparing the results on the expression of AMACR, EZH2, and TMPRSS2-ERG cancer markers obtained by immunoblotting, immunofluorescence staining, and RT-PCR showed that AMACR and EZH2 were expressed in all localized cancer samples (100%) in contrast to TMPRSS2-ERG, which was expressed only in some samples (Table 1). Here, ERG is linked to cancer.
