Manuka honey has demonstrated the potential to inhibit the proliferation of human breast cancer cells and stimulate apoptosis in these cells.
Animal Study Breast Cancer Honey
In the experiment, Manuka honey was applied to three different types of cells: MCF-7 human breast cancer cells, MDA-MB-231 breast cancer cells, and non-malignant human mammary epithelial cells. The concentrations applied ranged from 0.3 to 5.0% to observe different effects. In addition to inhibiting cancer cell proliferation, the honey was tested for its ability to cause apoptosis (cell death) among the MCF-7 cells. It was also compared to the effects of tamoxifen, an antiestrogen medication used in breast cancer treatment.
The results showed that Manuka honey was able to significantly inhibit the proliferation of MCF-7 cells, though its effects were less pronounced in the MDA-MB-231 breast cancer cells. The non-malignant cells were not affected. The honey's antitumor activity was comparable to that of tamoxifen. Moreover, Manuka honey stimulated apoptosis in the MCF-7 cells. It was also observed that the honey activated AMPK, which inhibits specific cellular growth signals, and reduced STAT3 levels, a protein often elevated in tumors.
