This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer is the second leading cause of death in privileged countries. Tremendous efforts have been done to improve the efficiency of cancer treatment. Anti-cancer drug resistance is still a major problem in failure of cancer therapy. Microsomal glutathione transferase 1 (MGST1) is a membrane protein located in the endoplasmic reticulum and the outer membrane of mitochondria. MGST1 is involved in the direct conjugation of glutathione to endogenous and exogenous toxic electrophilic hydrophobic compounds. The enzyme is often upregulated in tumours, and has been suggested to be an early marker of tumorigenesis. Furthermore, MGST1 has been connected to drug resistance in the clinic. Herein we show that MGST1 plays a potential role in inducing resistance against some commonly used anti-cancer drugs including chlorambucil, melphalan, carmustine, doxorubicin and cisplatin as examined in a human breast carcinoma cell line (MCF7) overexpressing MGST1. Further, we show that MGST1 dependent resistance against cisplatin can be reversed by ethacraplatin, a combination of the drug with a GST inhibitor (ethacrynic acid, EA). Upon cellular uptake, this compound is cleaved and the EA moiety is released. When cisplatin and ethacrynic acid were added together as such they were not as effective as ethacraplatin. Ethacraplatin can therefore be a useful alternative to overcome drug resistance by MGST1. Instead of inhibition of GSTs to reverse resistance, an alternate strategy is to use prodrugs that release cytotoxic molecules catalysed by GSTs. Here we show that prodox, a doxorubicin derivative, releases doxorubicin upon MGST1 and GSTP dependent catalysis. In MGST1 overexpressing cells the protection against prodox was lower compared to doxorubicin. With GSTP a dramatic effect was observed. Prodox was considerably more toxic to GSTP overexpressing than control cells. Thus prodrugs such as prodox, that are preferentially cleaved in GST overexpressing tumours, could be a useful therapeutic

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Oxidative Stress Cell Activation and Viral Infection written by C. Pasquier and published by Birkhäuser. This book was released on 2013-03-08 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of photosynthesis on our planet, all living organisms have been facing a new abundant, extremely reactive element, oxygen. This element is used for the synthesis of highly energetic compounds, but can also generate molecules capable of damaging constituents of living structures, including proteins, nucleic acids and lipids. It is therefore no surprise that all biological organisms have evolved multiple and sophisticated ways to reduce the detrimental effects of oxygen. For cells and tissues of highly organized animals, particularly cells of the immune system, superoxidation products play an important role, via oxidative stress, in activation, inflammation and viral and bacterial infections. We must be grateful to Drs. C. Pasquier, C. Auclair, L. Packer and R. Olivier for having brought together many specialists in an international meeting held in Paris in March 1993, at the Ministry of Research. This book comprises an impressive amount of recent knowledge, a real mine for the reader in this fast developing field of research. Furthermore, we should not forget that this basic research may lead in the future to new therapeutic approaches to the most important pathologies of the latter part of this century, including AIDS.
