RAB32 and central nervous system cancer: To verify the influence of the RAB32 DNA methylation level on glioma, we downloaded the methylation data of glioma patients from the CGGA database and found that the WHO grade of glioma was negatively correlated with the methylation level of RAB32 (Figure 5G), that is, the higher the expression level of RAB32 was, the lower the methylation level would be.
