研究问题

Cancer is a leading cause of death worldwide, driving continued research for innovative therapies with enhanced specificity and efficacy.

方法

Natural products have long been recognised as a valuable source of anticancer agents due to their structural diversity and unique biological activities.

核心结论

Building on the anticancer potential of oleuropein, a major olive tree (Olea europaea) metabolite, we evaluated a newly synthesised semi-synthetic analogue, GS32, for its cytotoxic activity in vitro.;Cytotoxicity assays revealed that GS32 exhibited broad-spectrum activity against various cancer cell lines, while also displaying differential toxicity between normal and cancerous cells.;Through transcriptomic analysis, we discovered that GS32 differentially disrupts key cellular pathways involved in stress response.;Importantly, targeted phosphoproteomic profiling uncovered context-dependent modulation of key signalling pathways, including the AKT/mTOR and NF-κB axes, as well as stress-response regulators. ‖ 结论:This study provides new mechanistic insight into the cellular effects of GS32 and identifies the compound as a candidate that merits further preclinical investigation.

B 级证据分级:B 级(同行评议临床前研究,主要为动物模型)

本文核心结论来自动物模型或体外细胞学,属临床前证据,不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义,与人类临床结局之间仍有距离。
