PDSS2 and astrocytoma (excluding glioblastoma): Because alterations of CoQ10 levels, PDSS2 protein levels, and COQ protein levels in astrocytomas might be associated with mitochondrial abnormalities related to the changes in CS activity or COX II level, we further compared the changes of these molecules after the values were normalized by CS activity or COX II level, which are shown in Figures S1 and S2, respectively, Supplementary Materials.
