Abstract

Recent studies have reported that Astragalus saponins (AST), extracted from the medicinal plant Astragalus membranaceus, possess anti‑tumor and apoptosis‑inducing abilities on various types of human cancer in vitro and in vivo. However, limited studies have explored how AST impacts glucose metabolism and growth conditions in vitro. The present study aimed to explore cell growth, proliferation, apoptosis and a series of glycolysis metabolic alterations associated with AST treatment in colorectal cancer (CRC) cells. MTT, a colony formation assay and flow cytometry demonstrated that AST dose‑dependently inhibited cell viability and induced apoptosis. Glucose uptake and lactate production measurements revealed that AST could inhibit glycolysis metabolism and lactate production. Reverse transcription‑quantitative polymerase chain reaction and western blot analysis identified that the expression levels of glycolytic enzymes were decreased by AST treatment in CRC cells. To uncover the possible impact of AST on inflammation and glucose metabolism in vivo, a dextran sulfate sodium (DSS)‑induced colitis mouse model was established. Notably, AST could inhibit growth and glycolysis metabolism in CRC cells in vitro, and attenuate the inflammatory response and tumor‑like aerobic glycolysis in the DSS‑induced mouse model. The findings indicated that AST may have the capacity to resist tumor‑associated inflammation and maintain normal glucose homeostasis, suggesting that AST could be a novel therapeutic strategy in CRC treatment.

摘要

最近的研究报告称,从药用植物黄芪中提取的黄芪皂苷(AST)在体外和体内对多种人类癌症具有抗肿瘤和诱导细胞凋亡的作用。然而,关于 AST 如何影响体外葡萄糖代谢和生长条件的研究有限。本研究旨在探讨 AST 处理对结直肠癌细胞(CRC)细胞生长、增殖、凋亡和一系列糖酵解代谢改变的影响。MTT、集落形成实验和流式细胞术表明,AST 呈剂量依赖性地抑制细胞活力并诱导细胞凋亡。葡萄糖摄取和乳酸产量测量表明,AST 可抑制糖酵解代谢和乳酸生成。逆转录-定量聚合酶链反应和 Western blot 分析表明,AST 处理可降低 CRC 细胞中糖酵解酶的表达水平。为了揭示 AST 对体内炎症和葡萄糖代谢的可能影响,建立了葡聚糖硫酸钠(DSS)诱导的结肠炎小鼠模型。值得注意的是,AST 可抑制 CRC 细胞在体外的生长和糖酵解代谢,并减轻 DSS 诱导的小鼠模型中的炎症反应和肿瘤样有氧糖酵解。这些发现表明,AST 可能具有抵抗与肿瘤相关的炎症和维持正常葡萄糖稳态的能力,提示 AST 可能成为 CRC 治疗的一种新的治疗策略。
