It is well documented that methamphetamine (MA) can cause obvious damage to the brain, but the exact mechanism is still unknown. In the present study, proteomic methods of two-dimensional gel electrophoresis in combination with mass spectrometry analysis were used to identify global protein profiles associated with MA-induced neurotoxicity. For the first time, 30 protein spots have been found differentially expressed in different regions of rat brain, including 14 in striatum, 12 in hippocampus and 4 in frontal cortex. The proteins identified by tandem mass spectrometry were Cu, Zn superoxide dismutase, dimethylarginine dimethylaminohydrolase 1, alpha synuclein, ubiquitin-conjugating enzyme E2N, stathmin 1, calcineurin B, cystatin B, subunit of mitochondrial H-ATP synthase, ATP synthase D chain, mitochondrial, NADH dehydrogenase(ubiquinone) Fe-S protein 8, glia maturation factor, beta, Ash-m, neurocalcin delta, myotrophin, profiling IIa, D-dopachrome tautomerase, and brain lipid binding protein. The known functions of these proteins were related to the pathogenesis of MA-induced neurotoxicity, including oxidative stress, degeneration/apoptosis, mitochontrial/energy metabolism and others. Of these proteins, alpha-synuclein was up-regulated, and ATP synthase D chain, mitochondrial was down-regulated in all brain regions. Two proteins, Cu, Zn superoxide dismutase, subunit of mitochondrial H-ATPsynthase were down-regulated and Ubiquitin-conjugating enzyme E2N, NADH dehydrogenase (ubiquinone) Fe-S protein 8 were up-regulated simultaneously in striatum and hippocaltum. The expression of dimethylarginine dimethylaminohydrolase 1 (DDAH 1) increased both in striatum and frontal cortex. The parallel expression patterns of these proteins suggest that the pathogenesis of MA neurotoxicity in different brain regions may share some same pathways.

Differences in the proteomic profiles of the brain amygdala in rats with different prognostic resistance to stress were found on the model of metabolic stress. Differential expression of tropomodulin-2, GTP-binding protein SAR1, peroxiredoxin-2, calcineurin B homologous protein 1, Ras-related protein Rab-14, glutathione S-transferase omega-1, Tcrb protein, and NADH dehydrogenase [ubiquinone] iron-sulfur protein 8 (mitochondrial) was shown to depend on the behavioral pattern of animals and stage of the study. Specific features were observed in the involvement of the amygdala in the stress response of specimens with various behavioral characteristics.
