The most prominent increase was observed in the GDF15 gene, and the expression levels of DJ-1 and MFGE8 were also significantly higher in high-grade tumours (Grade IV) compared to low- to intermediate-grade tumours (Grade II–III) (p = 0.016, p = 0.001, and p = 0.006 for DJ-1, GDF15, and MFGE8, respectively). Here, PARK7 is linked to neoplasm.
