As illustrated in KEGG pathway enrichment results, progesterone-mediated oocyte maturation, cell cycle, cellular senescence, oocyte meiosis, p53 signaling pathway, hepatitis B, viral carcinogenesis, human T-cell leukemia virus one infection, AMPK signaling pathway as well as FoxO signaling pathway (Figures 3G,H). Here, TP53 is linked to infection.
