The subdivision of the GBM cohort based on high and low hHSS1 expression showed that the levels of BRCA2 and ADAMTS1 expression on hHSS1-high expression group are significantly lower compared to hHSS1-low expression group (P < 0.00006 and P < 0.014, respectively) (Figure 9B). This evidence concerns the gene BRCA2 and glioblastoma.
