PrognoScan-based database analyses on PTEN using the same data set as in Figure 5A (GSE31210, GSE13507, GSE4412-GPL-96, and GSE19234 for patients with lung, bladder, brain, and skin cancers, respectively) actually revealed that patients with low intratumoral PTEN expressions exhibited poor overall survival (Figure 5D and Supplementary Figure S7). Here, PTEN is linked to skin cancer.
