KHDRBS2 and glioblastoma: For example, splicing factor NOVA1 and ES of CALM3 were good predictors for GBM patients, and the expression of NOVA1 was positively correlated with ES of CALM3 (Figures 5(b)–5(d)); splicing factor KHDRBS2 was a good predictor for GBM patients, while ES of U2AF1L4 was a poor predictor, and the expression of KHDRBS2 was negatively correlated with ES of U2AF1L4 (Figures 5(e)–5(g)).
