Copper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions.
SBHs, especially their copper complexes appeared to be potent inhibitors of DNA synthesis and cell growth in several human cancer cell lines, and rodent cancer cell lines. [ 141 ] [ 142 ] Salicylaldehyde pyrazole hydrazone (SPH) derivatives were found to inhibit the growth of A549 lung carcinoma cells. [ 146 ]
The presence of copper in molluscs was detected even earlier by Bartolomeo Bizio in 1833. [2] Hemocyanins are found in the Mollusca and Arthropoda , including cephalopods and crustaceans , and utilized by some land arthropods such as the tarantula Eurypelma californicum , [ 3 ] the emperor scorpion , [ 4 ] and the centipede Scutigera coleoptrata .
Since cancer is a genetic disease, two genomic events underlie acquired drug resistance: Genome alterations (e.g. gene amplification and deletion) and epigenetic modifications. Cancer cells are constantly using a variety of tools, involving genes, proteins, and altered pathways, to ensure their survival against antineoplastic drugs.
The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese " in drinking water .
These effects may promote Th1- and Th17 - biased immunity and alter monocyte and neutrophil migration from bone marrow. [ 7 ] [ 8 ] A healthy diet contains a multitude of micronutrients that have anti-inflammatory and immune boosting effects that can help prevent or treat autoimmune diseases.
Serum copper is low, which may seem paradoxical given that Wilson's disease is a disease of copper excess. However, 95% of plasma copper is carried by ceruloplasmin, which is often low in Wilson's disease. Urine copper is elevated in Wilson's disease and is collected for 24 hours in a bottle with a copper-free liner.
Copper deficiency, or hypocupremia, is defined as insufficient copper to meet the body's needs, or as a serum copper level below the normal range. [1] Symptoms may include fatigue , decreased red blood cells , early greying of the hair, and neurological problems presenting as numbness , tingling, muscle weakness, and ataxia . [ 2 ]
