PRL and endometrial cancer: The most interesting over-represented KEGG pathways were fatty acid metabolism (hsa01212), estrogen signaling pathway (hsa04915), oocyte meiosis (hsa04114), endometrial cancer (hsa05213), progesterone-mediated oocyte maturation (hsa04914), prolactin signaling pathway (hsa04917) (Fig. 4), long-term depression (hsa04730) (Fig. 5), steroid biosynthesis (hsa00100), and axon guidance (hsa04360) (Fig. 6) (Table 1).
