PTEN and glioblastoma: We confirmed the increased RNA levels of MGMT and phosphatase and tensin (PTEN) (Figures S1A–S1C) and the increased cell motility (migration rate) upon scratch formation (Figures S1D and S1E) in T98G glioblastoma cells expressing a p53 protein with Met-to-Ile substitution at position 237 of p53 compared with wt-p53-expressing U87 glioblastoma cells.
