PDCD10 and neoplasm: The IHC staining of the metastatic tumor on the stomach tissues of mice detected significantly higher expression of PDCD10 protein in the LV-miR-ctrl and OE-PDCD10 co-transfected groups, and this expression could be reversed in the LV-miR-222-3p and PDCD10 co-transfected group (Figure 3H).
