TRPM1 and glioblastoma: We found that three genes (EHF, TRPM1, and FXYD4) were upregulated in recurrent GBM tissues and in the module (dark turquoise) positively associated with recurrence state and recurrence times (Figure 6(a)), whereas 10 genes (CDH15, LHX5, TP73, FBN3, TLX1, C1QL4, COL2A, SEC61G, NEUROD4, and GPR139) showed low expression in recurrent GBM tissues and in the modules (blue and royalblue) negatively associated with recurrence state and recurrence times (Figure 6(b)).
