Fenton reaction induced cancer in wild type rats recapitulates genomic alterations observed in human cancer
…carcinogenesis in humans. Intraperitoneal administration of ferric nitrilotriacetate initiates a Fenton reaction in renal proximal tubules of rodents that ultimately leads to a high incidence of renal cell carcinoma (RCC) after repeated treatments. We performed high…

In response to Sharing different perspectives to understand asbestos-induced carcinogenesis: A comment to Jiang et al. (2016) by Alessandro Francesco Gualtieri (2017)
…hemoglobin. They stated that catalytic Fe(II) is more important than Fe(III) because it initiates a Fenton reaction. They described two roles of macrophages: scavenging fibers and promoting inflammation. They stated that chrysotile is carcinogenic…

Dual preventive benefits of iron elimination by desferal in asbestos-induced mesothelial carcinogenesis
…its effects on asbestos-induced peritoneal inflammation and iron deposition, as well as oxidative stress. Nitrilotriacetate was used to promote an iron-catalyzed Fenton reaction as a positive control. Desferal significantly decreased peritoneal fibrosis, iron deposition…

Rat model demonstrates a high risk of tremolite but a low risk of anthophyllite for mesothelial carcinogenesis
…In half of the animals, repeated intraperitoneal injections of nitrilotriacetate (NTA), an iron chelator to promote Fenton reaction, were performed to evaluate the potential involvement of iron overload. Tremolite induced MM with a high incidence (96…

Iron overload signature in chrysotile-induced malignant mesothelioma
…closely associated with iron overload: repeated administration of an iron chelator, nitrilotriacetic acid, which promotes the Fenton reaction, significantly reduced the period required for carcinogenesis; massive iron deposition was found in the peritoneal organs with high…

Iron overload as a major targetable pathogenesis of asbestos-induced mesothelial carcinogenesis
…compared with about 600 days for crocidolite and amosite. Nitrilotriacetic acid, a chemical that promotes iron-driven reactions, significantly promoted tumor development for all three fibers. Homozygous deletion (complete loss) of the Cdkn2a/2b tumor-suppressor…

Carbonic anhydrase 9 confers resistance to ferroptosis/apoptosis in malignant mesothelioma under hypoxia
…and acidity provide microenvironment for selection under evolutionary pressure and proliferation in cancer cells. Carbonic anhydrases (CAs) are a superfamily of metalloenzymes present in all life kingdoms, equilibrating the reactions among CO2, bicarbonate and H+. CA9…

Iron addiction with ferroptosis-resistance in asbestos-induced mesothelial carcinogenesis: Toward the era of mesothelioma prevention
…caused by modern industrial development. The major pathogenic mechanisms include oxidative stress either via catalytic reactions against the asbestos surface or frustrated phagocytosis of macrophages, and specific adsorption of hemoglobin and histones by asbestos fibers in…
