It is noticeable that there is no intersection between the two top 50 gene lists at all and no co-expression between EMCN and MUC15 (Spearman’s Correlation of 0.0264 with p-value of 0.592) either, implying the functional complementarity between EMCN and MUC15 and thus the rationality of the combination of the two genes in predicting prognosis for GC. The gene discussed is MUC15; the disease is gastric cancer.
