Because the induction of proneural-mesenchymal transition (PMT) has been shown to be similar to EMT and correlated with a mechanism for TMZ resistance in GBM cells [20], we next analyzed the correlation between the expression of the H2AFJ gene and PMT signature genes, which include WT1, TGFBR2, LYN, CD44, YKL40, and BCL2A1, in the GBM tissues from TCGA. The gene discussed is CD44; the disease is glioblastoma.
