Then, we selected the above mRNAs and lncRNAs for further analysis in TCGA cohort, 12 RNAs (5 mRNAs: KLHDC7B, CASP14, ESM1, PRSS1, and CST1; 7 lncRNAs: GAS5, SNHG12, MIR205HG, PVT1, LINC02474, UCA1, and TUG1) were upregulated in BCa tumor tissues (n = 372) compared to adjacent normal tissues (n = 19) (P < 0.05) were selected as candidate molecules (Supplementary Tables S2, S3). This evidence concerns the gene PRSS1 and neoplasm.
