The role of glutathione in copper metabolism and toxicity.

Cellular copper metabolism and the mechanism of resistance to copper toxicity were investigated using a wild type hepatoma cell line (HAC) and a copper-resistant cell line (HAC600) that accumulates copper and has a highly elevated level of metallothionein (MT). Of the enzymes involved in reactive oxygen metabolism, only glutathionine peroxidase was elevated (3-4-fold) in resistant cells, sugges...

Effect of Nano-Al2O3 on the Toxicity and Oxidative Stress of Copper towards Scenedesmus obliquus

Nano-Al₂O₃ has been widely used in various industries; unfortunately, it can be released into the aquatic environment. Although nano-Al₂O₃ is believed to be of low toxicity, it can interact with other pollutants in water, such as heavy metals. However, the interactions between nano-Al₂O₃ and heavy metals as well as the effect of nano-Al₂O₃ on the toxicity of the metals have been rarely investig...

Copper deficiency and copper toxicity in the rat.

OWEN, CHARLES A., JR., and JANE B. HAZELRIG. Copper deJi&nc~ and copper toxicify in the rat. Am. J, Physiol. 215(Z) : 334-338. I968.-Changes in metabolism of an intravexmusly injected tracer dose of 64Cu were measured in Sprague-Dawley rats subjected to copper loading, by addition of cupric acetate to the drinking water, or made copper deficient, by use of a milk-powder diet and copper-free wat...
