Growth arrest specific 1 (GAS1) is a pleiotropic protein that induces apoptosis and cell arrest in different tumors, but it is also involved in the development of the nervous system and other tissues and organs. This dual ability is likely caused by its capacity to interact both by inhibiting the intracellular signaling cascade induced by glial cell-line(More)
We have previously shown that the intrastriatal injection of the C-terminal domain of tetanus toxin (Hc-TeTx) protects the nigrostriatal-dopaminergic pathways and improves motor behavior in hemiparkinsonism-rat models caused by MPP(+) (1-methyl-4-phenylpyridinium). Here we have investigated the protective effects of the intramuscular application of the(More)
Iron is essential for proper neuronal functioning; however, excessive accumulation of brain iron is reported in Parkinson's, Alzheimer's, Huntington's diseases and amyotrophic lateral sclerosis. This indicates that dysregulated iron homeostasis is involved in the pathogenesis of these diseases. To determinate the effect of iron on oxidative stress and on(More)
UbcH7 is an ubiquitin-conjugating enzyme that interacts with parkin, an E3 ligase. The UbcH7-parkin complex promotes the ubiquitination and degradation of several proteins via the 26S proteasome. Cellular accumulation of the UbcH7-parkin targets alpha-synuclein, and synphilin-1 has been associated with Parkinson disease. In mouse liver,(More)
Exposure to mercury (Hg) occurs through different pathways and forms including methylmecury (MeHg) from seafood and rice, ethylmercury (EtHg), and elemental Hg (Hg0) from dental amalgams and artisanal gold mining. Once in the brain all these forms are transformed to inorganic Hg (I-Hg), where it bioaccumulates and remains for long periods. Hg is a(More)
