Melatonin inhibits both ER? activation and breast cancer cell proliferation induced by a metalloestrogen, cadmium

Cadmium (Cd) is a heavy metal affecting human health both through environmental and occupational exposure. There is evidence that Cd accumulates in several organs and is carcinogenic to humans. In…

Melatonin as an antibiotic: new insights into the actions of this ubiquitous molecule.

The incidence of serious infections caused by multidrug-resistant gram-positive and gram-negative bacteria has been increasing rapidly worldwide despite advances in antibacterial therapy in the last two decades. Among multidrug-resistant gram-positive…

Melatonin modulates the cadmium-induced expression of MT-2 and MT-1 metallothioneins in three lines of human tumor cells (MCF-7, MDA-MB-231 and HeLa)

Cadmium (Cd) is a human carcinogen present in tobacco smoke and contaminated industrial soils. Metallothioneins (MTs) are intracellular proteins involved in protecting against Cd. The toxic effects of Cd can…
