WDR18 and hydrops fetalis: Based on the target gene prediction and enrichment analyses, expression of representative predicted target mRNAs of some of the validated microRNAs were detected via RT-qPCR and these mRNAs are involved in all the treatments, including Elovl2, Lamp2, Atp6v0a1 and Wdr18 in CR, Wdr18 in EX and Atp6v0a1 and Wdr18 in HF (Fig. 7).
