Green Tea-Powered Nano "Missile" is the Latest Cancer-Fighting Drug

Green Tea 310x

Green tea antioxidant is a key component in new cancer-fighting drug delivery system.

Green tea is already refreshing on a number of levels -- as a drink, an antioxidant -- and now you can add cancer fighter and "missile delivery system" to its list of accolades.

The Institute of Bioengineering and Nanotechnology (IBN) within Singapore's A*STAR (Agency for Science, Technology, and Research) group has filed a patent for its "green tea nanocarrier," a new cancer drug delivery system that both protects the primary cancer drug, while acting as a drug on its own.

Green tea has a powerful antioxidant called epigallocatechin gallate (EGCG), which is the compound these cancer researchers are so interested in. EGCG has been praised for its anti-cancer properties in the past, but the IBN labs are taking its reputation to the limit. A version of the compound is being used as a nanocarrier for other anti-cancer drugs, shielding these drugs from a patient body's immune system. Once inside the body, the nanocarrier system acts like a cloaking device, shielding its drugs from being detected by the immune system, and filtered out of the body. No dilution of important (and costly) drugs is good enough news on its own, yeah?

But it gets better: according to IBN research, the EGCG nanocarrier "not only delivered protein drugs more effectively to the cancer cells, the combination of carrier and drug also dramatically reduced tumor growth compared with the drug alone."

The research team conducted animal studies to evaluate the performance of IBN's green tea-based protein delivery system. The study revealed that IBN's green tea nanocomplex loaded with Herceptin reduced tumor growth much more effectively when compared to administering Herceptin on its own. Using the new nanocarrier, twice as much drug accumulated in the cancer cells, indicating an improved tumor targeting ability. At the same time, the drug accumulation in the other organs was lowered substantially, by 70% in the liver and kidney, and by 40% in the lung.

As the quote says, this research is (or was) in the animal test phase, so it will be some time before we see this kind of cancer treatment out in the world, assuming it passes through the necessary regulations.

Maybe it can be marketed as a party drink. People would have "Green Tea Parties"... fun and health combined. I'll go and register a trademark...

I drink it every day with a bit of ginger. Very healthy stuff.

My understanding of nanotechnology has been horribly corrupted. But I still think it's cool.

"As the quote says, this research is (or was) in the animal test phase, so it will be some time before we see this kind of cancer treatment out in the world, assuming it passes through the necessary regulations."

This part always makes me sad. There's actually quite a few effective cancer fighting techniques that are stuck in animal testing or trials. Some that increase survival rate by 50% or more stay in trials for a over a decade. This is especially frustrating to see when conventional treatments such as Surgery, Chemo, and Radiation aren't very effective or simply too dangerous for certain types of cancer.

I don't see why this has to stay in animal trials when they have cancer patients that are dying for sure. Just give it to them and see if it works. What have they got to lose?

Mmmm green tea. Although I prefer mine to be delivered via traditional hot water instead of supplements or 'nano missiles'.

All I can say is, if you advertise that you're having a 'Green Tea Party' you can expect the local stoner population to descend upon your house.

Its important to realize that such stringent requirements to pass is there for a reason. yes, it slows down good drugs access, but it also folters out a lot of false positive drugs and a lot of drugs that are actually harmful. we saw relaxation of such drug regulation with AIDS drugs that didnt end very well as a lot of non-helpful drugs were sold as helpful.
