A recent study done by the Hormel Institute at the University of Minnesota, in Austin, indicates that green tea may help stop lung cancer growth.* The study, which focused on epigallocatechin gallate (EGCG), a polyphenol compound in the catechin family that is highly concentrated in green tea, set out to examine reports that EGCG suppresses lung cancer.
The study’s researchers found that EGCG interacted with the Ras-GTPase-activing protein SH3 domain-binding protein 1 (G3BP1). They also showed that EGCG suppressed the independent growth of H1299 and CL13 lung cancer cells, which contain a large amount of G3BP1 protein.
Additional results showed that EGCG effectively attenuated G3BP1 downstream signaling, including extracellular signal-regulated kinase and mitogen-activated protein kinase/extracellular signaling-regulated kinase.
The researchers concluded that green tea, which is one of the most popular beverages in the world, may in fact be a potent cancer fighter. The studies strongly indicated that green tea, via its EGCG content, suppresses lung tumorigenesis through its binding with G3BP1.
Editor’s note: Life Extension has advocated the use of green tea as a powerful antioxidant for years. This study is yet another confirmation that supplementing with green tea extract can be highly beneficial to the body.
