This study aimed to elucidate the effects of Hederagenin (HG) on hepatocellular carcinoma (HCC) and explore its potential molecular mechanisms.
Virtual screening was employed to identify potential targets within core pathways of liver cancer and to analyze the possible mechanisms of HG. CCK-8 assays were used to assess the viability of HCC cells, while Hoechst 33342/PI staining was utilized to evaluate apoptosis. The migration and invasion abilities of HCC cells were examined using Transwell and scratch assays, and single-cell cloning ability was assessed via colony formation assays. Subsequent qRT-PCR was conducted to determine the mRNA expression levels of FOXO1 and FOXO6 following HG treatment. Western blot (WB) analysis was employed to measure the protein expression levels of IGF1R, FOXO1, FOXO6, MMP2, MMP9, and VEGFA, as well as the phosphorylation status of FOXO1 Ser249.
Virtual screening indicated that HG might exert antitumor effects through the FOXO signaling pathway. Experimental results demonstrated that HG induces apoptosis in a dose-dependent manner and inhibits the proliferation, migration, invasion, and single-cell cloning ability of HCC cells. After HG treatment, FOXO1 expression was upregulated, while the expression levels of IGF1R, phosphorylated FOXO1 Ser249, MMP2, MMP9, and VEGFA were downregulated.
In summary, our study is the first to demonstrate that HG regulates the phosphorylation of FOXO1, affecting the proliferation, migration, and invasion of HCC cells. The findings suggest that HG can inhibit the migration of HCC cells in vitro. The data indicate that HG-mediated targeting of the FOXO1/FOXO6 pathway holds promise as a novel therapeutic approach.
本研究旨在阐明常春藤苷(HG)对肝细胞癌(HCC)的影响,并探讨其潜在的分子机制。
采用虚拟筛选方法鉴定肝癌核心途径中的潜在靶点,并分析 HG 的可能作用机制。CCK-8 法检测 HCC 细胞活力,Hoechst 33342/PI 染色检测细胞凋亡。Transwell 和划痕实验检测 HCC 细胞迁移和侵袭能力,集落形成实验检测细胞克隆形成能力。随后,通过 qRT-PCR 检测 HG 处理后 FOXO1 和 FOXO6 的 mRNA 表达水平。Western blot(WB)分析检测 IGF1R、FOXO1、FOXO6、MMP2、MMP9 和 VEGFA 的蛋白表达水平以及 FOXO1 Ser249 的磷酸化状态。
虚拟筛选表明,HG 可能通过 FOXO 信号通路发挥抗肿瘤作用。实验结果表明,HG 呈剂量依赖性诱导细胞凋亡,并抑制 HCC 细胞的增殖、迁移、侵袭和单细胞克隆能力。HG 处理后,FOXO1 表达上调,而 IGF1R、磷酸化 FOXO1 Ser249、MMP2、MMP9 和 VEGFA 的表达水平下调。
综上所述,本研究首次表明,HG 通过调节 FOXO1 的磷酸化来调节 HCC 细胞的增殖、迁移和侵袭。研究结果提示,HG 可抑制 HCC 细胞在体外的迁移。数据表明,HG 介导的 FOXO1/FOXO6 通路靶向治疗具有成为一种新的治疗方法的潜力。
