Article Synopsis
  • Dystonia is a movement disorder marked by involuntary muscle contractions, with various genetic and phenotypic forms, raising questions about shared causing mechanisms among them.
  • Mutations in the THAP1 gene are linked to a specific type of dystonia (DYT6), yet the gene's neural targets and how it leads to dystonia remain largely unexplored.
  • Using RNA-Seq in mouse models, researchers found that mutations lead to dysregulation in key biological pathways related to neuronal function, suggesting that these pathways could be common factors in different inherited dystonia types.

DYT1 dystonia is a neurological disease caused by dominant mutations in the TOR1A gene, encoding for the endoplasmic reticulum (ER)-resident protein torsinA. Recent reports linked expression of the DYT1-causing protein with dysregulation of eIF2α, a key component of the cellular response to ER stress known as the unfolded protein response (UPR). However, the response of the DYT1 mammalian brain to acute ER stress inducers has not been evaluated in vivo.

Article Synopsis
  • THAP1 is a transcription factor that, when mutated, leads to dystonia, specifically DYT6, a movement disorder.
  • The study reveals that normal THAP1 is crucial for maintaining embryonic stem cell survival, proliferation, and differentiation towards neuroectodermal tissues.
  • Mutations or loss of THAP1 increase cell death and disrupt the regulation of essential genes involved in differentiation, indicating its role in gene expression regulation.

Gulf War Illness (GWI), which affects at least one fourth of the 700,000 veterans deployed to the Gulf War (GW), is characterized by persistent and heterogeneous symptoms, including pain, fatigue and cognitive problems. As a consequence, this illness remains difficult to diagnose. Rodent models have been shown to exhibit different symptomatic features of GWI following exposure to particular GW agents (e.

Article Synopsis
  • The study investigates the long-term effects of simultaneous exposure to pyridostigmine bromide and permethrin in mice, focusing on protein-level changes in the central nervous system.
  • The researchers employed advanced proteomic techniques to analyze protein samples from the brain, revealing significant disruptions in mitochondrial, immune, and inflammatory pathways due to the exposure.
  • The findings highlight potential targets for future therapies aimed at mitigating the adverse health effects linked to these Gulf War agents.

Gulf War Illness (GWI) affects 25% of veterans from the 1990-1991 Gulf War (GW) and is accompanied by damage to the brain regions involved in memory processing. After twenty-five years, the chronic pathobiology of GWI is still unexplained. To address this problem, we examined the long-term consequences of GW exposures in an established GWI mouse model to identify biological processes that are relevant to the chronic symptoms of GWI.

Context • Telomeres are repeated deoxyribonucleic acid (DNA) sequences (TTAGGG) that are located on the 5' ends of chromosomes, and they control the life span of eukaryotic cells. Compelling evidence has shown that the length of a person's life is dictated by the limited number of times that a human cell can divide. The enzyme telomerase has been shown to bind to and extend the length of telomeres.

Gulf War Illness (GWI) is a chronic multisymptom illness with a central nervous system component that includes memory impairment as well as neurological and musculoskeletal deficits. Previous studies have shown that in the First Persian Gulf War conflict (1990-1991) exposure to Gulf War (GW) agents, such as pyridostigmine bromide (PB) and permethrin (PER), were key contributors to the etiology of GWI. For this study, we used our previously established mouse model of GW agent exposure (10 days PB+PER) and undertook an extensive lifelong neurobehavioral characterization of the mice from 11 days to 22.

Gulf War Illness (GWI) is a chronic multisymptom illness with a central nervous system component such as memory deficits, neurological, and musculoskeletal problems. There are ample data that demonstrate that exposure to Gulf War (GW) agents, such as pyridostigmine bromide (PB) and pesticides such as permethrin (PER), were key contributors to the etiology of GWI post deployment to the Persian GW. In the current study, we examined the consequences of acute (10 days) exposure to PB and PER in C57BL6 mice.

For two decades, 25% of the veterans who served in the 1991 Gulf War (GW) have been living with Gulf War Illness (GWI), a chronic multisymptom illness. Evidence suggests that brain structures involved in cognitive function may be affected in GWI. Gulf War agents such as the acetylcholinesterase (AChE) inhibitor pyridostigmine bromide (PB) and the pesticide permethrin (PER) are considered key etiogenic factors in GWI.
