Oxidative stress has been implicated in the pathogenesis of a wide variety of neuronal diseases, including ischemic neuronal injury, Alzheimer's disease, and Parkinson's disease. Thioredoxin reduces exposed protein disulfides and couples with peroxiredoxin to scavenge reactive oxygen species. Nerve growth factor (NGF) has profound effects on neurons,(More)
Thioredoxin (TRX) has a role in a variety of biological processes, including cytoprotection and the activation of transcription factors. Nerve growth factor (NGF) is a major survival factor of sympathetic neurons and promotes neurite outgrowth in rat pheochromocytoma PC12 cells. In this study, we showed that NGF induces TRX expression at protein and mRNA(More)
Previously, we demonstrated that dopamine D1 receptor (D1R) agonists inhibit epidermal growth factor (EGF)-induced passage of mouse fetal cerebral cortical precursor cells from the G1 phase to the S phase of the cell cycle. Here, we report that this action of D1R agonists may involve regulation of cyclin D, and P27, which respectively promote and suppress(More)
BACKGROUND The development of multidrug resistance is a major problem in the treatment of pathogenic microorganisms by distinct antimicrobial agents. Characterizing the genetic variation among plasmids from different bacterial species or strains is a key step towards understanding the mechanism of virulence and their evolution. RESULTS We applied a deep(More)
An emerging cavefish model, the cyprinid genus Sinocyclocheilus, is endemic to the massive southwestern karst area adjacent to the Qinghai-Tibetan Plateau of China. In order to understand whether orogeny influenced the evolution of these species, and how genomes change under isolation, especially in subterranean habitats, we performed whole-genome(More)
BACKGROUND Dopamine receptor-interacting proteins constitute a part of the dopamine system that is involved in regulation of dopamine receptor-associated intracellular signaling. Previously, we demonstrated that two such proteins, the D1 receptor-interacting protein calcyon and the D2 receptor-interacting protein neuronal calcium sensor-1 (NCS-1), were(More)
Previous studies documented significant behavioral changes in the offspring of cocaine-exposed mothers. We now explore the hypothesis that maternal cocaine exposure could alter the fetal epigenetic machinery sufficiently to cause lasting neurochemical and functional changes in the offspring. Pregnant CD1 mice were administered either saline or 20 mg/kg(More)
Aging is one of the strongest risk factors for Parkinson's disease (PD). SIRT2 has been implicated in the aging process. It is pertinent to investigate the role of SIRT2 in aging-related dopaminergic neurotoxicity and to develop effective therapeutic strategies for PD through the use of aging animals. In this study, we observed that rotenone induced(More)
There are few efficacious interventions to combat morphine dependence. Thioredoxin-1 (Trx-1) and heat shock protein 70 (Hsp70) are emerging as important modulators of neuronal function. They have been shown to be involved in cellular protective mechanisms against a variety of toxic stressors. This study was designed to investigate the effects of(More)
