Changes in patient-derived glioblastoma (GBM) organoid (PGO) gene expression upon temozolomide (TMZ) treatment. (A) Volcano plot of differentially expressed genes (identified by RNAseq) between TMZ-treated and TMZ-untreated PGOs (N = 3). (B) Dose–response curves of TMZ and JNK inhibitor combination treatment in PGOs (N = 5). PGOs were treated with either 30 uM TMZ, 5 uM SP600125, or a combination. (C) Cell viability results of PGOs treated with different dosages of TMZ and JNK inhibitor. Data are shown for 3 PGOs combined. (D) Bliss scores showing the interaction between different concentrations of TMZ and JNK inhibitor for 3 PGOs combined. A Bliss score >10 confirms a synergistic reacting when both treatment options are combined.
