Also, in order to analyze the relationship between TFRC and related miRNAs in PAAD and explore the molecular mechanism of TFRC, the STRING website analysis found that TFRC mainly interacts with mir-326, mir-378, mir-196b, mir-23a, mir-1247, mir-885, mir-30c-2, mir-2114, mir-488, and mir-190b (Figures 4A–C). The gene discussed is TFRC; the disease is pancreatic adenocarcinoma.
