The results indicated that high expression of VASH1 led to a decrease in tumor purity in CESC (Spearman-Correlation= −0.405), COAD (Spearman-Correlation= −0.606), KIRC (Spearman-Correlation= −0.366), LGG (Spearman-Correlation= −0.139), LUAD (Spearman-Correlation= −0.482), LUSC (Spearman-Correlation= −0.493), OV (Spearman-Correlation= −0.355), PRAD (Spearman-Correlation= −0.458), and UCEC (Spearman-Correlation= −0.300), which verified that VASH1 was inversely related to tumor purity (Figure 4). The gene discussed is VASH1; the disease is neoplasm.
