Therefore, IR activated the expression of genes related to the mitogen-activated protein kinase (MAPK) signaling pathway, proteoglycans in cancer, lipid and atherosclerosis, Rap1 signaling pathway, etc., and suppressed the expression of genes related to the neuronal system of glutamatergic synapse, oxytocin, calcium signaling pathways, etc., in IH, regardless of the type of control used (SO-r or IR-c). The gene discussed is OXT; the disease is isolated hemihyperplasia.
