Transcriptome analysis of the cerebral cortex of acrylamide-exposed wild-type and IL-1β-knockout mice.

Acrylamide is an environmental electrophile that has been produced in large amounts for many years. There is concern about the adverse health effects of acrylamide exposure due to its widespread industrial use and also presence in commonly consumed foods and others. IL-1β is a key cytokine that protects the brain from inflammatory insults, but its role in acrylamide-induced neurotoxicity remains unknown.

Deletion of IL-1β exacerbates acrylamide-induced neurotoxicity in mice.

Acrylamide is a neurotoxicant in human and experimental animals. Interleukin-1β (IL-1β) is a proinflammatory cytokine known as a critical component of brain reaction to any insult or neurodegenerative pathologies, though its role in electrophile-induced neurotoxicity remains elusive. The aim of this study was to investigate the role of IL-1β in acrylamide-induced neurotoxicity in mice.

Exposure to Benzo[a]pyrene Decreases Noradrenergic and Serotonergic Axons in Hippocampus of Mouse Brain.

Epidemiological studies showed the association between air pollution and dementia. A soluble fraction of particulate matters including polycyclic aromatic hydrocarbons (PAHs) is suspected to be involved with the adverse effects of air pollution on the central nervous system of humans. It is also reported that exposure to benzopyrene (B[a]P), which is one of the PAHs, caused deterioration of neurobehavioral performance in workers.

Nrf2 Activation Attenuates Acrylamide-Induced Neuropathy in Mice.

Acrylamide is a well characterized neurotoxicant known to cause neuropathy and encephalopathy in humans and experimental animals. To investigate the role of nuclear factor erythroid 2-related factor 2 (Nrf2) in acrylamide-induced neuropathy, male C57Bl/6JJcl adult mice were exposed to acrylamide at 0, 200 or 300 ppm in drinking water and co-administered with subcutaneous injections of sulforaphane, a known activator of the Nrf2 signaling pathway at 0 or 25 mg/kg body weight daily for 4 weeks. Assessments for neurotoxicity, hepatotoxicity, oxidative stress as well as messenger RNA-expression analysis for Nrf2-antioxidant and pro-inflammatory cytokine genes were conducted.

Comparative Expression Analysis of Inflammatory and Immune-related Genes in Cattle During Acute Infection with Foot-and-mouth Disease Virus in Egypt.

Introduction: Foot-and-mouth disease is a highly infectious viral disease affecting all cloven-footed domestic animals. The three foot-and-mouth disease virus (FMDV) serotypes A, O and SAT2 are at present the greatest threat to susceptible animals in Egypt. The aim of the present study was, for the host factors associated with different FMDV infections in cattle during the acute phase, to compare these factors' influence on the expression of the , , , , , and inflammatory and immune-related genes.

RNA Splicing: Basic Aspects Underlie Antitumor Targeting.

Background: RNA splicing, a fundamental step in gene expression, is aimed at intron removal and ordering of exons to form the protein's reading frame.

Objective: This review is focused on the role of RNA splicing in cancer biology; the splicing abnormalities that lead to tumor progression emerge as targets for therapeutic intervention.

Methods: We discuss the role of aberrant mRNA splicing in carcinogenesis and drug response.
