The discovery of WWP2 could lead to new drug advancements within the next decade  (Source: sciencedaily.com)
Could lead to the development of new drugs for aggressive cancers within the next decade

University of East Anglia researchers may have found a way to prevent the spread of cancer through the discovery of a rogue gene. 

Andrew Chantry, study leader from the University of East Anglia's School of Biological Sciences, and Dr. Surinder Soond, of the University of East Anglia, have discovered a rogue gene that, if blocked by proper medication, could prevent the spread of cancer

The discovery of the rogue gene came about when the team of researchers was studying 'Smads,' which are natural cancer cell inhibitors in the human body. 

The rogue gene is called WWP2, and it is an enzymic bonding agent. It is found within cancer cells and helps the spread of cancer by attacking Smads in the human body, which are supposed to stop the spread of cancer. 

"The late stages of cancer involve a process known as metastasis - a critical phase in the progression of the disease that cannot currently be treated or prevented," said Chantry. "The challenge now is to identify a potent drug that will get inside cancer cells and destroy the activity of the rogue gene. This is a difficult but not impossible task, made easier by the deeper understanding of the biological processes revealed in this study."

In the lab, researchers found that the levels of the natural inhibitor increased when WWP2 was blocked. This caused the cancer cells to remain dormant. 

Chantry and Soond hope this research leads to the development of drugs that can block WWP2. This would allow Smads to prevent the spread of cancer, and doctors could perform surgery on primary tumors without worrying about the spread of the disease.  

According to Chantry, these drugs could be developed within the next decade, taking researchers one step closer to success in the war on cancer. They're aiming to stop the spread of some of the most aggressive cancers such as brain, colon, skin and breast cancer

This study was published in Oncogene.

Lets see how long it takes the FDA to approve drug treatments based on this discovery. Since I would love to see how many people Die from delays from the FDA.

Actually, the FDA has the Fast Track Development Program for drugs under development that treat serious illnesses like cancer. And the whole purpose of placing breaks on the sale and distribution of new drugs is to make sure that they are safe and efficacious, that they do what they are meant to do. Hence time and clinical trials...

I know about the FDA and all their manipulative programs. Limiting citizen's options when it comes to their health/life.

Sorry the FDA's track record is poor. I rather see something like a UL label on drugs rather than see a FDA label. At least with a third party, I have the choice to take the drug even though its not approved.

It is easy to have a cavalier attitude like this when we and our loved ones are healthy, but when we and our loved ones have a condition which will terminate their life earlier than expected, or handicap their life, or even they just need relief from some severe bout of illness, then our cavalier attitude ... may become a curse and not a saviour.
Like it or not, most of us aren't pharmaceutical experts, so even if we are told every chemical in a drug and its percentage, that is meaningless to us. The only thing that is meaningful is will it help or not. Every good government has an interest in ensuring that the drugs sold will work as claimed, the conditions needed for each drug to work successfully, and the things to avoid doing.
Maybe the government could have done things differently and still got the same result while spending less taxpayers money, but maybe that process would also have cost more taxpayers money in other ways. Like it or not, the process they have is the one that, for whatever reason, is the one they have.

'Good Government' what constitutes good?
I believe much more good will come from allowing you to choose what you put in your own body.

You can still have the FDA approval however it shouldn't stop you from taking a drug. Infact thousands of products are tested by the Underwriters lab every year. They stand by their work of testing it. If no one trusted UL then no one would trust your brand. Then you would have to find another third party to test your product.

Btw who is to say government and their employee's have more incentive to care what happens more than the people you are buying the drug from? Drug companies are not perfect, every drug has a chance to hurt you. The biggest threat to drug companies are Class action/personal lawsuits, if enough people get together and file claims against them it:

first damages their brand for future business
second all the money they have to pay out to injured people from their product.

Thats the reason we have a court system LETS USE IT and stop wasting lives and billions of dollars for nothing.

So TRUST the guy trying to sell you something instead??

Funny how you types distrust the government so, but place all your trust in someone trying to make money off of you..
LMAO

Why would you trust an entity that has monopolistic control over much of your day to day life? An entity that actively limits your choices to suit the interests of those that lobby the best for laws that don't do anything, but make life worse for the common man?

At least the person selling to you if he wants to continue to have an income must meet your needs. Of course there will always be fraud, there would be less fraud if there was more choices and more competition in an economic system.

Fraud happens to you every day in the terms of government protected monopolies, inflation tax, taxes in general that takes your money to pay towards governments own interests.

Your BS monitor is off my friend.

The FDA process is terrible, about 5x slower than it needs to be, and I would say as a doctor that hundreds of thousands of people die each year needlessly because of it.

We have a drug that showed the ability to cure cancer in otherwise untreatable animals 13 years ago. In clinical trials it can cure otherwise untreatable patients with widespread tumors and even those left uncured live substantially longer. BUT after 13 years the FDA is still thinking about it ... even after thousands of patients have now benefited from it in clinical trials. Some of the first patients given weeks to live are still alive, tumor-free 7+ years later.

Critically ill patients should at least be able to choose to try experimental medicines but they can't. The whole system needs to be revamped so that "lifestyle" medicines go through the current, stringent process and have post-approval follow-up (sorely lacking now) BUT life-saving medicines are made available ASAP.

Really, and what drug is that?

The FDA does a vital role. They protect us from the companies just outputting a new snake oil once a week to fleece us with empty promises before we catch on. Think of Viocodin and Percocet which slipped by the FDA and were found to be deadly later on, and thus recalled. Without the FDA at all, that would be happening constantly.

You better believe we should be slow when it comes to drugs. Unintended consequences are the RULE and the NORM not the exception with drug design. And for very good biological reasons. We are all slightly chemically different, nothing will work for everyone, and there will always be side effects. It's a matter of balancing the good above the harm, and that's what the FDA process attempts to screen.

#1 piece of advice for molecular animal studies: mice are not humans.

Just yesterday, our group discussed anthrax vaccine development and the suitability of the mouse model. There were a number of live attenuated and protein subunit vaccines that have AMAZING efficacy (near 100% survival against lethal challenge of anthrax spores) in mice, but are only weakly immunogenic in humans - thus you don't get much of an antibody response. Gamma tocopherols, a potent ROS/RNS and anti-inflammatory scavenger, on the other hand, have almost pathetic oral bioavailability in rats, but have reasonably bioavailability in humans, again due to any number of reasons.

Examples where animal studies do not translate into efficacious, well controlled human trials are everywhere. Literally thousands of anti-cancer drugs have been tried in animals, but failed to demonstrate safety, dose dependent therapeutic effects, or efficacy in humans. Just to get a reasonable example: AstraZeneca's zibotentan, a endothelial receptor inhibitor, passed all animal studies, safety, and even phase II, but failed to demonstrate prolonged survival in a phase III trial of prostate cancer ( http://www.fiercebiotech.com/story/azs-zibotentan-... ). These things literally happen every day.

Don't let anyone tell you that if something works in mice, it'll work in humans. But yes, people are desperate, and desperate people try these things. In fact, the FDA process allows critically ill, desperate patients to try these things ... and sometimes they do work. There's a reason they are experimental drugs though.

Another example: PLX4032 ( http://en.wikipedia.org/wiki/PLX4032 ), a B-Raf inhibitor was a topic of a talk here a few months ago (about B-Raf). Promising results in animals, amazing results in humans against otherwise incurable melanoma cancers. Did people sign up? Of course. The only problem is that after 12 months or so, the tumor becomes resistant to PLX4032 inhibition and recurs. Is a 12 month increase in survival worth it? Of course, and it'll probably get FDA approved. But these things are by no means magic bullets.
