| Description | Zinc ions (Zn2+) are essential elements necessary for the normal function of mammalian cells. They participate in the regulation of the immune system, gene expression, energy metabolism, signal transduction and perform a structural function. However, an increased level of these ions is toxic, and so needs to be controlled. This control is primarily carried out by zinc transporters and zinc-binding proteins, in particular, metallothioneins. Prostatic tissue is very specific in Zn2+metabolism. Its cells accumulate a greater quantity of these ions (up to ten times more). Prostate cancer, a common cancer of men, is characterized by diverse and not very clear mechanisms, which serve to maintain Zn2+ levels. This unusual metabolism of Zn2+ has two important implications: -participation in the pathogenesis of the disease (due to apoptosis) and - increased serum levels of metallothioneins (with potential use of these proteins as markers for this disease). |
