Using web-based applications to conduct KM plot, univariate hazard ratio, landmark analysis, quantile survival analysis, and competing risk analysis, there were significant positive correlations between the high expression of NF-κB-p65 (Rel A), C/EBPβ, and HDAC3 in gastric cancer and overall survival and relapse-free survival, as annotated in the GSE34942 for NF-κB-p65 (RELA) and GSE62254 for C/EBPB datasets by TCGA as presented in the PROGgeneV2 (Fig. 5A and B, respectively). The gene discussed is HDAC3; the disease is gastric cancer.
