DUSP1 and glioblastoma: Results from the RNA-seq analysis (Fig. 6) determined that the neuroprotective agent dual-specificity phosphatase 1 (DUSP1) (also known as mitogen-activated protein kinase phosphatase 1 (MKP-1)), able to induce neurite outgrowth in neurons, was significantly increased 2.9 fold (p = 5.33 × 10−100) in CP-673451 treated U87 GBM cells compared to control [32].
