Metallothioneins are small, high-Cys-containing proteins present in a wide variety of organisms including vertebrates, invertebrates, fungi, cyanobacteria, and higher plants (Hamer, 1986). Metallothioneins play a role in heavy metal detoxification, especially in respect to cadmium, copper, and zinc (Hamer, 1986). Gene disruptions of the bakers’ yeast Cupl locus that encodes a metallothionein an...
Metallothioneins (MT) are common proteins in animal tissues. These proteins take part in the homeostasis of the ions of the metals which are necessary for the proper metabolism of the organism (zinc, copper), biosynthesis regulation and zincprotein activity (for example the activity of the zinc-dependant transcription factors) and they also take part in the detoxication of the tissue from toxic...
PURPOSE To identify those metallothionein and alpha-crystallin/small heat-shock genes induced by toxic metals in human lens cells and to evaluate the levels of these metals between young and aged human lenses. METHODS Human SRA01/04 and primary human lens epithelial cells were cultured and exposed to Cd(2+), Cu(2+), and Zn(2+). The levels of lens metallothioneins (Ig, If, Ih, Ie, and IIa) and...
