APOE and hydrops fetalis: In addition, we analyzed the expressions of LXRs target genes such as ApoE, LPL, ABCG1, and ABCA1. The results showed that CPE significantly decreased the expression levels of LXRβ and LPL; meanwhile CFSE decreased that of ApoE. We also found that the expression of ABCG1 was significantly up-regulated by both CPE and CFSE treatment compared to that of HF treatment alone.
