Abstract
Background
The inflammatory response and myocardial remodeling play critical roles in the progression of heart failure (HF) following myocardial infarction (MI). Isoliquiritigenin (ISL) possesses anti-inflammatory properties and has been investigated in cardiovascular diseases such as atherosclerosis. However, the effects and mechanism of ISL on MI-induced HF remain unclear. This research aimed to explore the effects and mechanism of ISL in the treatment of HF on the basis of network pharmacology, transcriptomics, and experimental verification.
Methods and results
We established an MI-induced HF mouse model in which ISL was administered via gavage for 28 days. Ultrasonic cardiogram data were collected from the mice, and pathological staining was conducted. Then, network pharmacology and molecular docking were performed. Transcriptomic analysis was also conducted on mouse myocardial tissue. Ultimately, we integrated transcriptomic data and network pharmacology to reveal the underlying mechanism, with the results verified through in vivo experiments. Our experiments indicated that ISL improved cardiac function, preserved myocardial structure, inhibited collagen fiber accumulation, reduced inflammatory factor secretion, and mitigated myocardial cell apoptosis in mice with MI-induced HF. A combination of transcriptomics and network pharmacology analysis revealed that core targets of ISL related to HF were significantly enriched in the Tumor Necrosis Factor (TNF) signaling pathway. Molecular docking validation demonstrated that ISL shows strong binding to these core targets. Additionally, in vivo experiments verified that ISL protects against HF post-MI by inhibiting the TNF signaling pathway.
Conclusion
We clarified the anti-inflammatory and antimyocardial remodeling mechanisms of ISL in the treatment of HF post-MI, which involves the TNF signaling pathway.
期刊介绍：
Toxicology and Applied Pharmacology publishes original scientific research of relevance to animals or humans pertaining to the action of chemicals, drugs, or chemically-defined natural products.
Regular articles address mechanistic approaches to physiological, pharmacologic, biochemical, cellular, or molecular understanding of toxicologic/pathologic lesions and to methods used to describe these responses. Safety Science articles address outstanding state-of-the-art preclinical and human translational characterization of drug and chemical safety employing cutting-edge science. Highly significant Regulatory Safety Science articles will also be considered in this category. Papers concerned with alternatives to the use of experimental animals are encouraged.
Short articles report on high impact studies of broad interest to readers of TAAP that would benefit from rapid publication. These articles should contain no more than a combined total of four figures and tables. Authors should include in their cover letter the justification for consideration of their manuscript as a short article.
