Therefore, based on diseases and target genes in the pathomechanism network of diabetic cardiomyopathy, we predicted a pool of lncRNAs such as GAS5, MALAT1, SNHG15, LOXL1-AS1, H19, MIAT, PRINS, TINCR, NEAT1, MEG3, TUG1, PVT1, GREM1, HOTAIR, and CASC5. The gene discussed is PVT1; the disease is diabetic cardiomyopathy.
