ASAH1 and glioblastoma: While the mesenchymal subtype, which is known for its highly invasive and migratory phenotype [29], had significantly higher ASAH1 mRNA in the TCGA GBM Agilent-4502A dataset (Figure 1E), consistently signficant difference in ASAH1 mRNA levels were not detected across subtypes among the datasets (Figure 1D,F).
