Through analyzing the pathways of DMGs, we obtained several important pathways, including “Regulation of lipolysis in adipocytes, Oxytocin signaling pathway, Glycosphingolipid biosynthesis-lacto and neolacto series, Glycosaminoglycan biosynthesis-keratan sulfate, Morphine addiction, Thyroid cancer, Histidine metabolism, Focal adhesion, Rap1 signaling pathway, and Transcriptional misregulation in cancer”. This evidence concerns the gene OXT and thyroid gland carcinoma.
