The pathway traverses from ICEES to ROBOKOP to demonstrate an association between ovarian cancer and the gene PTH (parathyroid hormone), which ROBOKOP associates with the chemical substances—calcitriol, calcium atom, vitamin D, calcium carbonate, phosphane, adenine, phosphate, phosphorous, maxacalcitol, calciol, calcium, lithium hydride, and cinacalcet. The gene discussed is PTH; the disease is ovarian cancer.
