Honey, propolis, and passionflower contain a flavone known as chrysin. Researchers are studying chrysin to prove its potential to stop cancer cells growth. Chrysin cancer therapeutic potential is of great interest and numerous studies have been done to illustrate this potential. It is associated protein pathways effectively suppress tumor growth within the body. It is shown to have the ability to kill breast, prostate, lung, liver, and stomach cancerous cells. It can block Phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) and Mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling in different animals against various cancers. Chrysin has the potential to kill breast cancer cells in a laboratory setting by inhibiting their cell division. Chrysin strongly suppresses Matrix metalloproteinase-9 (MMP-9), Urokinase plasminogen activator (uPA) and Vascular endothelial growth factor (VEGF), i.e. factors that can cause cancer. Chrysin has the ability to suppress the androgen receptor (AR), a protein necessary for prostate cancer development and metastasis. It starts the caspase cascade and blocks protein synthesis to kill lung cancer cells. Unnecessary apoptosis can be prevented by stopping certain protein pathways. Chrysin significantly decreased lung cancer metastasis in various animal-modeled studies. Chrysin induces apoptosis and stops colon cancer cells in the G2/M cell cycle phase. Chrysin suppresses colon cancer-promoting cyclin B1 and cyclin-dependent kinase 2. Chrysin suppressed cyclin B1 and CDK2 production in order to stop cancerous growth. Chrysin prevents tumor growth and cancer spread by blocking blood vessel expansion. Chrysin’s solubility, accessibility and bioavailability may limit its medical use. Chrysin targets numerous cancer-related communication pathways present in cells. Chrysin may reduce the chances of the onset of cancer, it can also serve as an alternative treatment as a whole to prevent and treat various cancers, but more clinical trials and research studies are needed to fully unlock its potential.
