Abstract

OBJECTIVES

Curdione is one of the active ingredients of a traditional Chinese herbal medicine- and established anti-tumor effects. Uterine leiomyosarcoma (uLMS) is a rare gynecological malignancy, with no standard therapeutic regimen at present. The aim of this study was to explore the potential anti-tumor impact of curdione in uLMS and elucidate the underlying mechanisms.

METHODS

functional assays were performed in the SK-UT-1 and SK-LMS-1 cell lines. The model of uLMS was established by subcutaneously injecting SK-UT-1 cells, and the tumor-bearing mice were intraperitoneally injected with curdione. Tumor weight and volume were measured at specific time points. The biosafety was evaluated by monitoring changes of body weight and the histopathology in the liver and kidney. The expression levels of relevant proteins were analyzed by western blotting and immunohistochemistry.

RESULTS

Curdione decreased the viability and proliferation of uLMS cells in a concentration and time-dependent manner. In addition, the curdione-treated cells exhibited significantly higher rates of apoptosis and autophagic death. Curdione also decreased the tumor weight and volume in the SK-UT-1 xenograft model compared to the untreated control without affecting the body bodyweight or pathological injury of liver and kidney tissues. At the molecular level, the anti-tumor effects of curdione were mediated by indoleamine-2, 3-dioxygenase-1 (IDO1).

CONCLUSION

Curdione exhibited an anti-uLMS effect and ; the underlying mechanism involved in IDO1 mediate apoptosis, autophagy, and G2/M phase arrest.

摘要

目的

莪术二酮是一种传统中药的活性成分,具有明确的抗肿瘤作用。子宫平滑肌肉瘤(uLMS)是一种罕见的妇科恶性肿瘤,目前尚无标准治疗方案。本研究旨在探讨莪术二酮对uLMS的潜在抗肿瘤作用,并阐明其潜在机制。

方法

在SK-UT-1和SK-LMS-1细胞系中进行功能实验。通过皮下注射SK-UT-1细胞建立uLMS模型,对荷瘤小鼠腹腔注射莪术二酮。在特定时间点测量肿瘤重量和体积。通过监测体重变化以及肝脏和肾脏的组织病理学来评估生物安全性。通过蛋白质印迹法和免疫组织化学分析相关蛋白的表达水平。

结果

莪术二酮以浓度和时间依赖性方式降低uLMS细胞的活力和增殖。此外,经莪术二酮处理的细胞表现出显著更高的凋亡率和自噬死亡率。与未处理的对照组相比,莪术二酮在SK-UT-1异种移植模型中也降低了肿瘤重量和体积,且不影响体重或肝肾组织的病理损伤。在分子水平上,莪术二酮的抗肿瘤作用由吲哚胺-2,3-双加氧酶-1(IDO1)介导。

结论

莪术二酮表现出抗uLMS作用,其潜在机制涉及IDO1介导的凋亡、自噬和G2/M期阻滞。
