摘要

本研究探讨了2-甲氧基雌二醇（2-ME）通过下调缺氧诱导因子1α（HIF-1α）克服MCF-7乳腺癌细胞对他莫昔芬（TAM）耐药性的潜力。作者通过一系列体外实验证明，将2-ME与TAM结合可增强对耐药细胞的细胞毒性作用，增加细胞凋亡标志物，并降低胆固醇和甘油三酯水平。虽然这些研究结果突显了一种很有前景的治疗方法，但体内或临床数据的缺乏限制了其直接的临床应用。未来的研究应侧重于在动物模型中验证这些结果，并探索长期疗效和分子机制。

Comment on "2-methoxyestradiol sensitizes tamoxifen-resistant MCF-7 breast cancer cells via downregulating HIF-1α".

This study investigates the potential of 2-methoxyestradiol (2-ME) to overcome tamoxifen (TAM) resistance in MCF-7 breast cancer cells by downregulating hypoxia-inducible factor 1 alpha (HIF-1α). Through a series of in vitro experiments, the authors demonstrate that combining 2-ME with TAM enhances the cytotoxic effects on resistant cells, increases apoptosis markers, and reduces cholesterol and triglyceride levels. While the findings highlight a promising therapeutic approach, the lack of in vivo or clinical data limits direct clinical application. Future research should focus on validating these results in animal models and exploring long-term efficacy and molecular mechanisms.
