Doxorubicin (Dox) is widely utilized in the clinical treatment of various cancers. Despite its efficacy, Dox induces numerous adverse effects in humans with significant cardiotoxicity, posing a major limitation to its use. injection (SII), derived from , exhibits notable anti-inflammatory and anti-oxidative stress properties. However, its potential protective effects against Dox-induced cardiotoxicity (DIC) remain unexplored. In this study, we investigate the ability of SII to mitigate DIC and elucidate the underlying mechanisms through experimental research and network pharmacology analysis. Results from both and experiments reveal that SII treatment significantly improves Dox-induced cardiac dysfunction, reducing pathological alterations and fibrosis in cardiomyocytes. Moreover, SII has cardioprotective effects by diminishing the inflammation, oxidative stress, and apoptosis triggered by Dox. Network pharmacological analysis further shows that SII downregulates P53 protein expression by activating the AKT/MDM2 signaling pathway, thus attenuating DIC. In conclusion, this study confirms that SII mitigates DIC through downregulation of the AKT/MDM2/P53 signaling pathway, suggesting a promising therapeutic strategy for alleviating DIC.
阿霉素(Dox)广泛应用于各种癌症的临床治疗。尽管其疗效显著,但阿霉素会在人体中引发多种不良反应,具有明显的心脏毒性,这对其使用构成了重大限制。来源于[具体来源未给出]的注射剂(SII)具有显著的抗炎和抗氧化应激特性。然而,其对阿霉素诱导的心脏毒性(DIC)的潜在保护作用仍未得到探索。在本研究中,我们通过实验研究和网络药理学分析,探究了SII减轻DIC的能力并阐明其潜在机制。体外实验和体内实验的结果均表明,SII治疗可显著改善阿霉素诱导的心脏功能障碍,减少心肌细胞的病理改变和纤维化。此外,SII通过减轻阿霉素引发的炎症、氧化应激和细胞凋亡而具有心脏保护作用。网络药理学分析进一步表明,SII通过激活AKT/MDM2信号通路下调P53蛋白表达,从而减轻DIC。总之,本研究证实SII通过下调AKT/MDM2/P53信号通路减轻DIC,为缓解DIC提供了一种有前景的治疗策略。
