In Stromal Score analysis, we found that in 6 types of tumors [GBM (r = 0.674, p = 1.68e-21), GBMLGG (r = 0.669, p = 2.65e-86), SARC (r = 0.661, p = 1.00e-33), KICH (r = 0.647, p = 5.66e-09), LGG (r = 0.616, p = 4.42e-54) and SKCM-M (r = 0.602, p = 5.34e-36), threshold value: p < 0.05, r > 0.60] have positively correlations with the expression of VNN1. Here, VNN1 is linked to glioblastoma.
