Quantitative changes of brain isatin-binding proteins of rats with the rotenone-induced experimental parkinsonism.
Isatin (indoldione-2,3) is an endogenous regulator found in humans and animals. It exhibits a broad range of biological activity mediated by numerous isatin-binding proteins. Isatin produces neuroprotective effects in several experimental models of diseases, including Parkinsonism induced by the neurotoxin MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine).Rotenone (a neurotoxin used to modeling Parkinson's disease in rodents) causes significant changes in the profile of isatin-binding proteins of rat brain. Comparative proteomic identification of brain proteins of control rats and the rats with the rotenone-induced Parkinsonian syndrome (PS) revealed significant quantitative changes of 86 proteins under the influence of rotenone. This neurotoxin mainly caused the increase of the quantity of proteins involved in signal transduction and regulation of enzyme activity (24), proteins involved in cytoskeleton formation and exocytosis (23), and enzymes involved in energy generation and carbohydrate metabolism (19). However, only 11 of these proteins referred to isatin-binding proteins; the content of eight of them increased while the content of three proteins decreased. This suggests that the dramatic change of the profile of isatin-binding proteins, found in the development of the rotenone-induced PS, comes from changes in the state of the pre-existing molecules of proteins, rather than altered expression of corresponding genes.

期刊介绍:
The aim of the Russian-language journal "Biomeditsinskaya Khimiya" (Biomedical Chemistry) is to introduce the latest results obtained by scientists from Russia and other Republics of the Former Soviet Union. The Journal will cover all major areas of Biomedical chemistry, including neurochemistry, clinical chemistry, molecular biology of pathological processes, gene therapy, development of new drugs and their biochemical pharmacology, introduction and advertisement of new (biochemical) methods into experimental and clinical medicine etc. The Journal also publish review articles. All issues of journal usually contain invited reviews. Papers written in Russian contain abstract (in English).
