The KEGG pathway analysis showed that the DE-miRNAs in women with RPL were enriched in TGF-beta signaling pathway, Hippo signaling pathway, lysine degradation, hepatitis B, proteoglycans in cancer, fatty acid biosynthesis, oocyte meiosis, protein processing in endoplasmic reticulum, p53 signaling pathway, and FoxO signaling pathway (Table 4, Figure 4B). Here, TP53 is linked to cancer.
