Ovarian cancer is one of the most common tumors affecting females, significantly disrupting their quality of life. Agrimonolide, an extract derived from Agrimony (Agrimonia pilosa Ledeb.), has been shown to exert various regulatory effects on several diseases. Notably, recent studies indicate that Agrimonolide may attenuate the progression of ovarian cancer. However, the detailed regulatory mechanisms of Agrimonolide in this context require further investigation.
To determine the significance of HIF1A as a key target in ovarian cancer and its potential underlying signaling pathway.
Cell viability and proliferation were assessed using CCK-8 and colony formation assays. Glucose uptake and lactate production were measured using commercial kits, and the extracellular acidification rate (ECAR) was evaluated. Protein expression levels were analyzed through western blotting.
Our network pharmacology analysis identified HIF1A as a crucial target and signaling pathway in ovarian cancer. Furthermore, treatment with Agrimonolide (20 μM and 40 μM) inhibited the growth of ovarian cancer cells. Agrimonolide also reduced glycolytic activity in these cells. Additionally, Agrimonolide treatment led to decreased expression levels of HIF1A, HK2, and LDHA in ovarian cancer cells. Rescue assays revealed that glucose uptake and lactate production were diminished following Agrimonolide treatment; however, these effects were reversed upon overexpression of HIF1A.
This study showed that Agrimonolide can suppress glycolysis in ovarian cancer cells by modulating HIF1A, supporting Agrimonolide as a promising therapeutic agent for ovarian cancer treatment.
卵巢癌是女性最常见的肿瘤之一,严重影响其生活质量。从龙芽草(Agrimonia pilosa Ledeb.)中提取的苍术苷,已被证明对多种疾病具有多种调节作用。值得注意的是,最近的研究表明苍术苷可能会减缓卵巢癌的进展。然而,苍术苷在这种情况下的详细调节机制需要进一步研究。
确定 HIF1A 作为卵巢癌的关键靶点及其潜在的信号通路的重要性。
使用 CCK-8 和集落形成测定法评估细胞活力和增殖。使用商业试剂盒测量葡萄糖摄取和乳酸生成,评估细胞外酸化率(ECAR)。通过 Western blot 分析蛋白质表达水平。
我们的网络药理学分析确定 HIF1A 是卵巢癌的关键靶点和信号通路。此外,苍术苷(20μM 和 40μM)处理抑制卵巢癌细胞的生长。苍术苷还降低了这些细胞的糖酵解活性。此外,苍术苷处理导致卵巢癌细胞中 HIF1A、HK2 和 LDHA 的表达水平降低。挽救实验表明,苍术苷处理后葡萄糖摄取和乳酸生成减少;然而,过表达 HIF1A 后,这些作用得到逆转。
这项研究表明,苍术苷可以通过调节 HIF1A 抑制卵巢癌细胞的糖酵解,支持苍术苷作为卵巢癌治疗的有前途的治疗剂。
