RAB32 and central nervous system cancer: In support of our conclusions, we found a significant negative correlation between RAB32 DNA methylation and the expression of RAB32 mRNA and its subtypes of probes in the nonpromoter region, such as cg04113075 (Figure 5D), from the SMART online analysis platform (Figure S2), Afterward, we became very interested in whether the DNA methylation level of RAB32 affected the prognosis of glioma patients.
