Briefly, the tumor (N = 7) and adjacent (N = 6) tissues of OS patients were collected and stained using IHC, showing that CSNK2A2, VDAC2, and MIF were markedly upregulated in OS tissues compared with the control tissues (Fig. 7A, B), whereas the expression of ODC1 showed no significant change (Fig. 7A, B). This evidence concerns the gene VDAC2 and neoplasm.
