Additionally, in patients with glioblastoma, Jung et al. showed that high NNMT expression levels are not associated with prognosis in TCGA GBM dataset, however, NNMT upregulation is found to be correlated with poor prognosis in five other cohorts, including Rembrandt, TCGA GBMLGG, Phillips, and Gravendeel, and Nutt (Jung et al., 2017). The gene discussed is NNMT; the disease is glioblastoma.
