PAQR7 and hepatocellular carcinoma: Up-regulated levels of PAQR7 in HCC tissues only, at both the transcriptional (Figure 2(C-1)) and translational levels (Figure 4E), as well as our observation that increased expression of PAQR7 is associated with decreased survival in HCC patients (Figure 6(B-3)), support its use as a potential prognostic biomarker to differentiate between HCCs and CCAs.
