Crystals of cadmium, zinc metallothionein.
Single crystals have been grown of Cd,Zn metallothionein isoform II from rat liver. The space group is P41212(P43212) with unit cell dimensions a = b = 31.0 A and c = 120.0 A, and one molecule in the crystallographic asymmetric unit. The crystals are square bipyramids elongated on the tetragonal c-axis and are grown by repetitive seeding. The crystals are suitable for high resolution structure ...

متن کاملEffects of cadmium and zinc on tissue levels of metallothionein.
Although the induced synthesis of metallothionein (MT) after exposure to certain metals has been known for some time, there is little information on the quantitation of MT in various tissues. In this study, tissue MT concentrations were measured by a modified Cd-saturation method in tissues of adult male rats after injection of different metal salts. There were differences in tissue levels of M...
متن کاملZinc and low-dose of cadmium protect sertoli cells against toxic-dose of cadmium: The role of metallothionein
BACKGROUND The impact of cadmium (Cd) on male infertility may be related to the interaction with metal-binding proteins known as metallothioneins (Mts). Trace elements like zinc (Zn) have protective effects on testicular damage induced by Cd. OBJECTIVE We determined the effect of Zn and low-dose Cd pre-treatment on the expression of Mt1 and Mt2 genes on testicular Sertoli cells. MATERIALS A...
متن کاملInduction of metallothionein synthesis by cadmium and zinc in cultured rabbit kidney cells (RK-13).
The effects of increasing concentrations of Zn(II) and Cd(II) on the expression of the four isometallothioneins (isoMTs), namely MT-1a, MT-2a, MT-2d and MT-2e, in rabbit kidney cells (RK-13) and the development of cellular tolerance to these metal ions were studied. The results showed that, whereas in parental cells MT concentration was low and composed nearly exclusively of MT-2a and MT-1a, al...
