USP39-knockdown inhibits cell proliferation and migration and promotes cell death in human pancreatic cancer cells. (A) Western blot analysis revealed that the protein levels of USP39 significantly decreased in PANC-1 and MIAPaCa-2 cells when transfected with USP39 shRNA. β-Actin served as an internal control. (B) Representative results of colony formation in PANC-1 and MIAPaCa-2 cells. (C) USP39 knockdown suppressed migration capabilities in PANC-1 and MIAPaCa-2 cells (scale bar: 200 μm). (D) Representative results of the EdU assays (scale bar: 100 μm) in PANC-1 and MIAPaCa-2 cells. (E) Representative results of the cell death assay (scale bar: 100 μm) in PANC-1 and MIAPaCa-2 cells.
