Possible Mechanisms of Green Tea and Its Constituents against Cancer

Molecules. 2018 Sep 7;23(9):2284. doi: 10.3390/molecules23092284.


A number of epidemiological, clinical, and experimental researches have indicated that administration of green tea appears to have anti-cancer activity. According to findings of laboratory cell culture studies, a diverse mechanism has been observed underlying the effects of green tea catechins against cancer. These mechanisms include anti-oxidant activity, cell cycle regulation, receptor tyrosine kinase pathway inhibition, immune system modulation, and epigenetic modification control. This review discusses the results of these studies to provide more insight into the effects of green tea administration on cancers observed to date in this research field.

Keywords: cancer; catechin; chemoprevention; green tea; receptor tyrosine kinase.
