PTH and cancer: The KEGG pathways were inositol phosphate metabolism, glutamatergic synapse, phosphatidylinositol signaling system, cholinergic synapse, dopaminergic synapse, erbb signaling pathway, nitrogen metabolism, morphine addiction, spinocerebellar ataxia, oxytocin signaling pathway, choline metabolism in cancer, hippo signaling pathway—multiple species, insulin secretion, parathyroid hormone synthesis, secretion and action, and gnrh secretion (Figure 12).
