PTPRR and hepatocellular carcinoma: Furthermore, we integrated the predicted target genes of miR-587 and the upregulated genes in HCC, and results showed that 13 differentially expressed target genes of miR-587 were found in HCC including OSR2, RAD54B, FAM81A, DKKL1, PTHLH, RPSA, ZNF781, ZNF92, CD163L1, ZNF138, PTPRR, TXNL4A, and ZNF124 (Figure 4(b)).
