Hematoxylin and eosin (H&E) staining identified an increase in tumor cells in the VCP-overexpressing group, while the immunohistochemical (IHC) analysis showed that in the VCP gene activation group, the expression of FASN, VCP, and USP2 in tumor cells was relatively increased (Fig. 8C, D). The gene discussed is VCP; the disease is neoplasm.
