Figure 2. Necroptosis-related lncRNAs in STAD. (A) The volcano plot of all lncRNAs differential expressions associated with necroptosis in STAD. The red represents the expression of upregulation, the green represents the expression of downregulation, and the black represents that the expression has not changed. (B) The analytical relationship network diagram between necroptosis-related genes and lncRNA. (C) The heat maps were plotted based on the differential gene expression of the first 50 lncRNAs with the most significant upregulation and downregulation. FC, fold change; NRG, necroptosis gene.
