HSS1 expression analysis in GBM from the TCGA dataset. A) Correlation analysis between hHSS1 and BRCA2 expression (r = −0.224, P < 0.0005). B) Log2-transformed gene expression levels for selected genes between high and low-hHSS1 expression cohorts. Mean gene expression levels between cohorts were compared by two-tailed Student's t-test, P < 0.01. P values - HSS1 lo vs. HSS1 hi : (hHSS1, P < 6.55e−98), (ADAMTS1, P < 0.014), (BRCA2, P < 0.00006), Endostatin (COL18A1), P < 0.048).
