摘要

本研究旨在探讨天麻颗粒在结直肠癌中的诱导铁凋亡作用，并阐明其分子机制。铁下垂是一种铁依赖性的细胞死亡形式，是癌症治疗的新靶点。我们将网络药理学与实验验证相结合，探索TMG通过调节铁下垂的抗癌潜力。结果网络药理学鉴定出382个铁中毒相关基因与12944个crc相关靶点重叠（p < 0.05），其中SLC7A11、GPX4、SAT1、PTGS2和GLS2优先作为核心靶点。在体外，TMG剂量依赖性地抑制结直肠癌细胞增殖（p < 0.05），提高活性氧（p < 0.05）和亚铁离子水平（p < 0.01），这种作用被铁下垂抑制剂铁抑素-1逆转。c-Casp3水平不变（p > 0.05），不包括细胞凋亡。透射电镜显示线粒体嵴碎裂和空泡化，这是铁下垂的标志特征。分子分析显示，tmg介导SLC7A11和GPX4下调，SAT1、PTGS2和GLS2上调（p < 0.05）。在异种移植模型中，高剂量TMG （23.2 g/kg）减少了肿瘤体积，减轻了恶病质，升高了肿瘤内ROS和Fe2+水平（p < 0.01），证实了铁下垂在体内的诱导作用。结论stmg通过双重抑制SLC7A11/GPX4和激活SAT1/PTGS2/GLS2来诱导铁下垂，从而抑制结直肠癌的进展。这项研究将传统医学和铁下垂生物学联系起来，将TMG定位为CRC的一种新的治疗候选药物。引用方式：丁宁，唐旭，张勇，等。天麻颗粒：连接传统医学与现代科学，通过铁下垂对抗结直肠癌。中国生物医学工程学报（英文版）；2009;38。https://doi.org/10.1016/j.ejbt.2025.06.004。

Tianma granules: Bridging traditional medicine and modern science to combat colorectal cancer via ferroptosis

Background

This study aims to investigate the ferroptosis-inducing effects of Tianma Granules (TMGs) in colorectal cancer and elucidate its molecular mechanisms. Ferroptosis, an iron-dependent form of regulated cell death, represents a novel therapeutic target for cancer. We combined network pharmacology with experimental validation to explore TMG’s anti-cancer potential through ferroptosis modulation.

Results

Network pharmacology identified 382 ferroptosis-related genes overlapping with 12,944 CRC-associated targets (p < 0.05), with SLC7A11, GPX4, SAT1, PTGS2, and GLS2 prioritized as core targets. In vitro, TMG dose-dependently suppressed CRC cell proliferation (p < 0.05), elevated reactive oxygen species (p < 0.05) and ferrous ion levels (p < 0.01), effects reversed by ferroptosis inhibitor, Ferrostatin-1. c-Casp3 levels were unchanged (p > 0.05), excluding apoptosis. Transmission electron microscopy revealed mitochondrial cristae fragmentation and vacuolation, hallmark features of ferroptosis. Molecular analyses demonstrated TMG-mediated downregulation of SLC7A11 and GPX4, alongside upregulation of SAT1, PTGS2, and GLS2 (p < 0.05). In xenograft models, high-dose TMG (23.2 g/kg) reduced tumor volume, attenuated cachexia, and elevated intratumoral ROS and Fe²⁺ levels (p < 0.01), corroborating ferroptosis induction in vivo.

Conclusions

TMG suppresses CRC progression by inducing ferroptosis via dual inhibition of SLC7A11/GPX4 and activation of SAT1/PTGS2/GLS2. This study bridges traditional medicine and ferroptosis biology, positioning TMG as a novel therapeutic candidate for CRC.
