Additionally, we evaluated for the first time the involvement of different uptake and efflux transporters—namely OCTs, CTR1, MATEs, and ATP7A/B—in the accumulation mechanisms of 1 in human ovarian cancer cells in vitro, using competitive inhibitors/substrates and determining the intracellular metal content by ICP-MS. The gene discussed is SLC31A1; the disease is ovarian carcinoma.
