Effects of Carvacrol on Cognitive Function and Apoptotic Gene Expression in Trimethyltin- Induced Hippocampal Injury in Rats.
Objective: Trimethyltin (TMT) chloride is an organotin compound used in industry. It has been linked to generating reactive oxygen species (ROS), inflammatory processes, and neuronal death. Carvacrol is a monoterpene phenol found in the Lamiaceae plant family, modulating inflammatory conditions and necroptosis in neural tissue. This study aimed to investigate the neuroprotective effects of carvacrol in a rat model of hippocampal neuronal injury induced by TMT.
Materials and methods: In this experimental study, sixty male Wistar rats were randomly divided into five groups (n=12): group 1 receiving saline, group 2 received dimethyl sulfoxide (DMSO) as a vehicle for 21 days, group 3 receiving a single dose of TMT (8 mg/kg) and groups 4 and 5 receiving carvacrol 40 and 70 mg/kg daily for 21 days after a single dose of TMT. All injections were intraperitoneal (I.P.). Caspase-3, Bax, Bcl-2, and Bdnf gene expression and the number of pyknotic neurons in the hippocampus were quantified. Spatial memory was assessed with a radial arm maze.
Results: Statistical analysis of histological data revealed the carvacrol significantly attenuated cognitive dysfunction and the number of pyknotic neurons in the hippocampal CA1 region of rats treated with TMT. Based on real-time polymerase chain reaction (PCR), carvacrol modulated the expression of genes involved in apoptosis (Bax and Caspase-3) and upregulated anti-apoptotic (Bcl-2) and brain derived neurotrophic factor (Bdnf) genes in the hippocampal tissue.
Conclusion: These findings revealed neuroprotective effects of carvacrol which might be mediated by apoptotic and anti-apopetotic factors.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
