Knockout of 5-Lipoxygenase Results in Age-Dependent Anxiety-Like Behavior in Female Mice
BACKGROUND The enzyme 5-lipoxygenase (5LO) has been implicated in a variety of neurological and psychiatric disorders including anxiety. Knockout of 5LO has previously been shown to alter anxiety-like behavior in mice at a young age but the effect of 5LO knockout on older animals has not been characterized. METHODOLOGY/PRINCIPAL FINDINGS Here we used the elevated plus maze behavioral paradigm...
متن کاملAge-Dependent Relevance of Endogenous 5-Lipoxygenase Derivatives in Anxiety-Like Behavior in Mice
When 5-lipoxygenase (5-LO) is inhibited, roughly half of the CNS effect of the prototypic endocannabinoid anandamide (AEA) is lost. Therefore, we decided to investigate whether inhibiting this enzyme would influence physiological functions classically described as being under control of the endocannabinoid system. Although 5-LO inhibition by MK-886 reduced lipoxin A4 levels in the brain, no eff...
متن کاملModulation of Anxiety-Like Behavior in Sildenafil Citrate-Treated Mice Placed in an Elevated Plus-Maze
Introduction: Sildenafil, a phosphodiesterase-5 (PDE5) inhibitor, may have various effects on the central nervous system via the nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway. Preclinical studies have shown the controversial effect of sildenafil on anxiety-like behavior in animals. This study was undertaken to investigate the acute effect of sildenafil on anxiety-like behavior...
متن کاملAlterations in anxiety-like behavior following knockout of the uncoupling protein 2 (ucp2) gene in mice.
AIMS Uncoupling protein 2 (UCP2) is a mitochondrial protein that reduces oxidative stress and has a protective function in chronic inflammatory diseases such as multiple sclerosis, rheumatoid arthritis and systemic lupus erythematosus. UCP2 is strongly expressed in areas implicated in the central regulation of stress and anxiety. Therefore, we compared the neuroendocrine regulation of stress re...
متن کاملSex-dependent alterations in motor and anxiety-like behavior of aged bacterial peptidoglycan sensing molecule 2 knockout mice
Peptidoglycan recognition proteins (PGRPs) are key sensing-molecules of the innate immune system that specifically detect bacterial peptidoglycan (PGN) and its derivates. PGRPs have recently emerged as potential key regulators of normal brain development and behavior. To test the hypothesis that PGRPs play a role in motor control and anxiety-like behavior in later life, we used 15-month old mal...
