Figure 5. Differential expression analysis of (A) RNF139-AS1, (B) MIR194-2HG and (C) SLC1A5 in normal samples and GC samples by GTEx database, Ensembl database and Refgene database. Survival analysis by the GEPIA2 database shows (D) SLC1A5 is associated with overall survival. (E) Competing endogenous RNAs networks. Quadrilateral (lncRNA: MIR194-2HG), circular (miRNA: hsa-miR-125b-5p), octagonal (mRNA: SLC1A5).
