TNFSF14 and glioblastoma: In TCGA, the results showed repressed LIGHT expression in the LGG-Oligo subtype (IDHmut, 1p/19q codeletion) and LGG-Astro (IDHmut, 1p/19q non-codeletion) compared with the LGG-IDHwt group, while LIGHT expression in GBM-IDHwt was higher than that in the GBM-IDHmut group (Figure 1C).
