PU inhibited cisplatin‐AKI‐induced apoptosis in kidney cells by measuring levels of the apoptosis‐associated proteins B cell leukemia/lymphoma two (Bcl‐2), Bcl2‐Associated X protein (Bax), and cleaved‐caspase3 using Western blot and immunofluorescence (Figure 3). Here, BCL2 is linked to acute kidney injury.
