Copper is distributed to distinct localizations in the cell through diverse pathways. We demonstrate here that the delivery of copper to copper/zinc superoxide dismutase (SOD1) is mediated through a soluble factor identified as Saccharomyces cerevisiae LYS7 and human CCS (copper chaperone for SOD). This factor is specific for SOD1 and does not deliver copper to proteins in the mitochondria, nucleus, or secretory pathway. Yeast cells containing a lys7Delta null mutation have normal levels of SOD1 protein, but fail to incorporate copper into SOD1, which is therefore devoid of superoxide scavenging activity. LYS7 and CCS specifically restore the biosynthesis of holoSOD1 in vivo. Elucidation of the CCS copper delivery pathway may permit development of novel therapeutic approaches to human diseases that involve SOD1, including amyotrophic lateral sclerosis. 相似文献

The objective of this study was to examine the role of copper in neutrophil development and function. Mice were made copper deficient by feeding dams a diet containing 1.05 microg copper starting at parturition. Control mice were fed the same diet containing 6 microg copper. The pups were weaned to the diet and killed when they were 5-6 wk old. Peripheral blood cell counts, margination and cell maturity were measured. The response to an intraperitoneal injection of lipopolysaccharide (LPS) was also determined. Copper deficiency resulted in twice as many neutrophils and fewer than half the number of lymphocytes. Half as many cells in copper-deficient mice expressed Ly-6G, a granulocytic marker of cell maturity. In addition, copper-deficient cells expressed only half the amount of Ly-6G per cell than was expressed by copper-adequate cells. This suggested that the cells were younger, or arrested in their maturation as a result of copper deficiency. An arrest of maturation has been proposed as the cause of neutropenia in human copper deficiency. Injection of LPS in copper-adequate mice resulted in twice as many Ly-6G-expressing cells in the periphery. LPS injection into copper-deficient mice resulted in a severe leukopenia but did not influence Ly-6G expression any more than did copper deficiency alone. LPS treatment caused an increase in myeloperoxidase activity associated with the lungs of copper-deficient mice. The results suggest that although the neutrophils of copper-deficient mice are immature, they can be sequestered by the lung when stimulated to do so. 相似文献

立足我国铜工业现状,根据计量经济学理论与方法,结合1990~2009年铜消费及GDP数据,利用Eviews5.1软件作实证分析,结果表明铜消费与GDP间存在协整关系以及双向因果关系。须努力提高国内及海外铜资源开采力度、增加再生铜产量来提升我国铜供应能力,同时调低铜冶炼及加工业产能的扩张速度,以确保国内铜工业产业链协调发展及促进国民经济持续快速发展。 相似文献
