They further validated six potential biomarkers (ERO1L: endoplasmic reticulum oxidoreductin 1, NARS, PABPC4: poly(A)-binding proteins, RCC1: regulator of chromosome condensation 1, RPS25: ribosomal protein S25, and TARS: threonyl-TRNA synthetase) which were highly expressed in adenocarcinoma tissues compared to adjacent normal tissues. Here, RPS25 is linked to adenocarcinoma.
