Trichloroethylene exposure aggravates behavioral abnormalities in mice that are deficient in superoxide dismutase. Regul Toxicol Pharmacol 2016; 79:83-90.

Abstract
Trichloroethylene (TCE) has been implicated as a causative agent for Parkinson's disease (PD). The administration of TCE to rodents induces neurotoxicity associated with dopaminergic neuron death, and evidence suggests that oxidative stress as a major player in the progression of PD. Here we report on TCE-induced behavioral abnormality in mice that are deficient in superoxide dismutase 1 (SOD1). Wild-type (WT) and SOD1-deficient (Sod1(-/-)) mice were intraperitoneally administered TCE (500 mg/kg) over a period of 4 weeks. Although the TCE-administrated Sod1(-/-) mice showed marked abnormal motor behavior, no significant differences were observed among the experimental groups by biochemical and histopathological analyses. However, treating mouse neuroblastoma-derived NB2a cells with TCE resulted in the down regulation of the SOD1 protein and elevated oxidative stress under conditions where SOD1 production was suppressed. Taken together, these data indicate that SOD1 plays a pivotal role in protecting motor neuron function against TCE toxicity.

Abstract
BACKGROUND Genetic and epigenetic factors interacting with the environment over time are the main causes of complex diseases such as autoimmune diseases (ADs). Among the environmental factors are organic solvents (OSs), which are chemical compounds used routinely in commercial industries. Since controversy exists over whether ADs are caused by OSs, a systematic review and meta-analysis were performed to assess the association between OSs and ADs. METHODS AND FINDINGS The systematic search was done in the PubMed, SCOPUS, SciELO and LILACS databases up to February 2012. Any type of study that used accepted classification criteria for ADs and had information about exposure to OSs was selected. Out of a total of 103 articles retrieved, 33 were finally included in the meta-analysis. The final odds ratios (ORs) and 95% confidence intervals (CIs) were obtained by the random effect model. A sensitivity analysis confirmed results were not sensitive to restrictions on the data included. Publication bias was trivial. Exposure to OSs was associated to systemic sclerosis, primary systemic vasculitis and multiple sclerosis individually and also to all the ADs evaluated and taken together as a single trait (OR: 1.54; 95% CI: 1.25-1.92; p-value<0.001). CONCLUSION Exposure to OSs is a risk factor for developing ADs. As a corollary, individuals with non-modifiable risk factors (i.e., familial autoimmunity or carrying genetic factors) should avoid any exposure to OSs in order to avoid increasing their risk of ADs.

Abstract
Microbial products, including lipopolysaccharides, may be involved in the pathogenesis of inflammatory skin diseases. We examined the effect of hirsutenoxime on the Toll-like receptor 4-mediated activation of Akt and nuclear factor (NF)-κB in lipopolysaccharide-stimulated keratinocytes. Hirsutenoxime, a cell signaling Akt inhibitor, and Bay 11-7085, an inhibitor of NF-κB activation, attenuated the lipopolysaccharide-induced expression of Toll-like receptor 4, activation of NF-κB and Akt, and the production of chemokines and reactive oxygen/nitrogen species. Hirsutenoxime may reduce the Toll-like receptor 4 expression-mediated NF-κB activation, which is regulated by the Akt pathway in keratinocytes exposed to lipopolysaccharides. This effect may reduce the skin inflammatory response.
