What is The Inhibitory Effects of 5‐Hydroxy‐3,6,7,8,3′,4′‐hexamethoxyflavone on Human Colon Cancer Cells about?
## Abstract **Scope:** Previously, we reported that 5‐hydroxy‐3,6,7,8,3′,4′‐hexamethoxyflavone (5HHMF), a polymethoxyflavone found in citrus peels, potently inhibited the growth of multiple human colon cancer cells. Herein, we further investigated the anti‐cancer mechanisms of 5HHMF in human colon cancer cells. **Methods and results:** Colony formation assay revealed that 5HHMF dose dependently inhibited colony formation of multiple colon cancer cells. Western blot analysis demonstrated 5HHMF decreased nuclear β‐catenin levels and increased the E‐cadherin level in a dose‐dependent manner. 5HHMF also modified plasma membrane‐associated proteins, such as K‐Ras, EGFR, and their downstream effectors, such as Akt. Moreover, treatments with 5HHMF inhibited nuclear translocation of NF‐κB, which may contribute to its anti‐cancer effects. Add‐back study showed that the inhibitory effect of 5HHMF was not associated with the production of reactive oxygen species (ROS). In addition, 5HHMF treatment inhibited the capillary tube formation of human umbilical vein endothelial cells (HUVECs) on matrigel, suggesting a potential anti‐tumor angiogenesis effect. **Conclusion:** Our results demonstrated
