KEGG analysis revealed that the differentially expressed genes were significantly involved in the Chemokine signaling pathway, Prolactin signaling pathway, MAPK signaling pathway, Peroxisome, C-type lectin receptor signaling pathway, endocytosis, thyroid hormone signaling pathway, necroptosis, and thyroid cancer (Fig. 6d). The gene discussed is PRL; the disease is thyroid gland carcinoma.
