Cortex cinnamomi extract prevents streptozotocin- and cytokine-induced β-cell damage by inhibiting NF-κB

Figure 3 Expression of iNOS protein and mRNA induced by STZ in mice pancreases. Mice were injected with STZ (100 mg/kg) after being pretreated for 7 d with various concentrations of CCE. iNOS protein (A) and mRNA (B) were isolated and detected by Western blotting and RT-PCR, respectively. Representative results from three independent experiments are shown.
