PPARG and hydrops fetalis: Further analysis of the biochemical indices of serum and liver tissue showed that AcAc treatment significantly reduced markers related to HF and liver injury compared with the CCl4-treated group; however, the improvement of these indices was significantly attenuated or completely disappeared after PPARγ interference, suggesting that the interference of PPARγ reversed the anti-fibrotic effect of AcAc (Figure 5B).
