Figure 4. Curcumin treatment reduced high glucose-induced caspase activation.

Protein levels of caspase 8 (A) and caspase 3 (B) in embryos cultured for 24 h under normal glucose and high glucose conditions, with or without 20 μM curcumin treatment. Experiments were repeated three times using three embryos from three different dams. NG: normal glucose; NG + Cur: normal glucose plus 20 μM curcumin; HG: high glucose; HG + Cur: high glucose plus 20 μM curcumin. * Indicates significant difference (p < 0.05) when compared to other groups.
