This includes VGF (Figure 5h), which is linked to promoting growth and survival in glioblastoma (Wang et al., 2018) and MDK (Figure 5i), which is highly expressed in malignant tumours (Filippou et al., 2020) and has been shown to play a role in chemoresistance (Lu et al., 2018). This evidence concerns the gene VGF and glioblastoma.
