BAX and hydrops fetalis: Figure 7C shows that compared with the control, the HF + STZ group exhibited increased Bax expression, whereas curcumin intervention could reverse the increase in Bax expression caused by HF + STZ treatment to some degree. Further analysis showed that compared with the control group, the HF + STZ group had significantly increased average optical densities, representing the relative value of Bax expression (p < 0.01) (Figure 7D). However, the average light density in the HF + Cur +STZ group was significantly lower than that in the HF + STZ group (p < 0.05).
