The target miRNA of LINC00857 (lnc Base, purple), the upstream miRNA regulator of TGFA (Targetscan, yellow), the down-regulated miRNA in PAAD obtained from the OncomiR website (OncomiR-DEGs, green), and the miRNAs that were meaningful for survival (OncomiR-survival) were intersected to obtain a common miRNA (orange). The gene discussed is TGFA; the disease is pancreatic adenocarcinoma.
