According to clinical data from the Chinese Glioma Genome Atlas (CGGA, http://www.cgga.org.cn/) database, the median survival time in the groups with high Prrx1 expression was shorter (n = 111) than that in the groups with low Prrx1 expression (n = 111) (Fig. 1G, P = 0.0036). Here, PRRX1 is linked to central nervous system cancer.
