Function[FRIL_HORSE] Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity). Publication Abstract from PubMedAIM: A Pt(II)-terpyridine compound, bearing two piperidine substituents at positions 2 and 2' of the terpyridine ligand (1), is highly cytotoxic and shows a mechanism of action distinct from cisplatin. 1 has been incorporated within the ferritin nanocage (AFt). MATERIALS & METHODS: Spectroscopic and crystallographic data of the Pt(II)-AFt nanocomposite have been collected and in vitro anticancer activity has been explored using cancer cells. RESULTS: Pt(II)-containing fragments bind His49, His114 and His132. Pt(II)-AFt nanocomposite is less cytotoxic than 1, but it is more toxic than cisplatin at high concentrations. The Pt(II)-AFt nanocomposite triggers necrosis in cancer cells, as free 1 does. CONCLUSION: Pt(II)-AFt nanocomposites are promising vehicles to deliver Pt-based drugs to cancer cells.
