Chemopreventive and anticarcinogenic effects of CuB and underlying mechanisms of action
Type of cancer explored with phytochemical CuB | Mechanism of action | Results | References |
---|---|---|---|
Breast cancer | Inhibits JAK-STAT3, VEGF/FAK/MMP-9 MAPK, HER2 integrin signaling pathways. Suppresses HER2-integrin signaling which downregulates α6 and β4 integrins. |
Exceptionally displays anti-angiogenic effects in metastatic cancer cells. Limits the growth of breast tumors. Integrins α6 and β4 that are overexpressed in breast cancer cells are downregulated as HER2-integrin signaling is suppressed. Suppresses the growth of breast cancer cells when combined with gemcitabine or docetaxel. Inhibits VEGF/FAK/MMP-9 signaling in highly metastatic breast cancer cells and has anti-angiogenic properties. |

Colon cancer | Decreases phosphorylation of JAK2 and STAT3. Reduces M2 macrophage polarization. |
Reduces the metastasis of colorectal cancer. | [7,20] |
