Furthermore, the target genes of miR-181a-5p and miR-125b-2-3p were enriched in several pathways, including the FoxO signaling pathway, prostate cancer, endometrial cancer, focal adhesion, hepatitis C, non-small cell lung cancer, mTOR signaling pathway, and central carbon metabolism in cancer, which correlated with placental function (Figure 5(b) and Supplementary Table S5). Here, MTOR is linked to hepatitis C virus infection.
