Further analysis showed that compared with the control group, the HF + STZ group had significantly decreased average optical densities, reflecting decreased Bcl-2 expression (p < 0.05), as shown in Figure 7B. However, the average optical densities in the HF + Cur + STZ group were significantly higher than those in the HF + STZ group (p < 0.05). This evidence concerns the gene BCL2 and hydrops fetalis.
