The qRT-PCR results, based on 15 clinical GBM and paired non-tumor brain tissue samples, showed that the mRNA levels of ALOX5AP, LGALS1, and PLA2G5 were significantly higher in GBM tumor tissues compared to non-tumor brain tissues (all p < 0.05) (Figure 7A). The gene discussed is PLA2G5; the disease is neoplasm.
