{ "DOI": "10.1159/000534343", "abstract": "<p>Introduction: Interventions targeting cholinergic neurotransmission like acetylcholinesterase (AChE) inhibition distinguish potential mechanisms to delay age-related impairments and attenuate deficits related to neurodegenerative diseases. However, the chronic effects of these interventions are not well-described. Methods: In the current study, global levels of cholinergic, cellular, synaptic, and inflammation-mediating proteins were assessed within the context of aging and chronic reduction of AChE activity. Long-term depletion of AChE activity was induced by using a mutant zebrafish line and they were compared with the wildtype group at young and old ages. Results: Results demonstrated that AChE activity was lower in both young and old mutants and this decrease coincided with a reduction in ACh content. Additionally, an overall age-related reduction in AChE activity and the AChE/ACh ratio was observed, this decline was more prominent in wildtype groups. The levels of an immature neuronal marker were upregulated in mutants, while a glial marker showed an overall reduction. Mutants had preserved levels of inhibitory and presynaptic elements with aging, whereas glutamate receptor subunit levels declined. Discussion/Conclusion: Long-term AChE activity depletion induces synaptic and cellular alterations. These data provide further insights into molecular targets and adaptive responses following the long-term reduction of AChE activity that was also targeted pharmacologically to treat neurodegenerative diseases in human subjects.</p>", "author": [ { "family": "Karoglu-Eravsar", "given": " Elif Tugce" }, { "family": "Tuz-Sasik", "given": " Melek Umay" }, { "family": "Karaduman", "given": " Aysenur" }, { "family": "Keskus", "given": " Ayse Gokce" }, { "family": "Arslan-Ergul", "given": " Ayca" }, { "family": "Konu", "given": " Ozlen" }, { "family": "Kafaligonul", "given": " Hulusi" }, { "family": "Adams", "given": " Michelle M." } ], "container_title": "GERONTOLOGY", "id": "270528", "issue": "12", "issued": { "date-parts": [ [ 2023, 1, 1 ] ] }, "page": "13", "title": "Long-term Acetylcholinesterase Depletion Alters the Levels of Key Synaptic Proteins while Maintaining Neuronal Markers in the Aging Zebrafish (Danio rerio) Brain", "type": "article-journal", "volume": "69" }
