Scientists Search Deep Sea Reefs for Wonder Drugs
ScienceDaily is reporting that a team of scientists will be venturing some 2000-3000 feet below the ocean surface in order to explore deep-sea reefs discovered last December. From the article: "A primary goal of the upcoming expedition, which is funded largely by the State of Florida's 'Florida Oceans Initiative,' will be to search for marine organisms that produce chemical compounds with the potential to treat human diseases such as cancer and Alzheimer's."
Modern man has an impeccable record for destroying the natural environment that produces his fruits & resources. Then we sit and bitch about how it went away. Reefs are probably going to be no different. They're harder to get at, but if the run-off doesn't destroy them, I'm sure our medical companies will.
There's a report written by the UN University that details the problems being raised by this treasure of "blue gold." One of the interesting sources it cites is Blue Genes: Sharing and Conserving the World's Aquatic Biodiversity (another interesting document on the global problem of sharing the world's oceans).
Hypothetical scenario time! So, Pfizer's scientists find that a fairly common sponge produces a natural chemical that slows the growth of cancer. Unfortunately, each sponge only produces an ounce of this chemical when refined and there is no way to naturally synthesize it on a mass scale. Pfizer tries to buy the rights to harvest the sponge at a restricted rate in Florida. But they have to get permits from the local, state & federal governments and it costs them a lot of money because they send people down to the reef to hand pick the sponges. Instead, they find a supplier in a third world country (possibly around Indonesia) that promises them mass quantities of the sponge at a reduced rate. Now, the government there forbids it too but an official receives a large sum from this company and suddenly Pfizer has got incoming shipments of the sponge. The problem is that the company working for Pfizer is doing so with total blatant disregard for the ecosystem & probably its workers.
A farfetched scenario? Or something that's happened so often in the past, we'd be naïve to imagine it to stop here?
My work here is dung.
Sorry, but cancer isn't a disease... its a mutation. You can't cure mutations, only give your body the ability to remove the mutated cells.
Hopefully, it won't be like...
The rainforest(s).
Lots of potential, but wasted.
If you read biology journals, you'll see that just about every third or fourth paper consists of "we pureed some sea sponge in a blender and extracted this compound. And look, it kills cancer cells (*cough* and non-cancerous cells too *cough*)!" The only thing different here is a somewhat deeper venue for collection. (this isn't to say that it's not important scientific work, just that it's rather commonplace and rarely leads to much of anything)
We really need to get back on this train. Oceanography wasn't really even around until relatively recent times. Even once it started catching on, it quickly died off. To date, one of our biggest contributions to oceanography and marine biology has been the H.M.S. Challenger in the 1870's, it's three year mission to explore strange... well, nevermind you get the picture. Sure we have made some large steps since then, but nothing that comes close.
Now I have "Octopus's Garden" running through my head. How strange.
You are not the customer.
For those who are not familiar with coral reefs and may go for a casual snorkel or swim sometime, please do not physically touch the coral itself as this kills it. Because of this, federal law requires swimmers to wear flotation jackets when nearby to avoid contact.
It takes 30,000 years to grow 1 cubic inch of coral, and the mistreatment of the reefs around Florida (1960s dynamite fishing, jewelry harvesting, etc.) has made it so that the reef off of the Florida Keys is the last living coral reef in the region.
Apparently, a lot of people tend to associate "disease" purely with illnesses directly caused by bacteria, virus, or protozoan...
The meek may inherit the earth, but the strong shall take the stars.
The production of antibiotics by fungi and other bacteria to reduce the population of competing organisms has been honed by centuries of evolution. If preserved, supported and studied the processes, and the compounds are there to be used.
The science is slow and tedious, but many of the cultures that live in these rich habitats are well versed in the properties of the flora they have around them.

"Don't let fools fool you. They are the clever ones."
How can we be expected to destroy them if we don't know where they are? Let's put more money into hunting down these "reef" things so we can pit-mine them for a solution to athlete's foot.
Or, maybe we can just leave them the hell alone. How about it scientists? Just a thought.
E Proelio Veritas.
In most cases of cancer(as I recall it it's about 70%), it is found that the protein p53 is in someway defect. p53 is the protein responsible for during a "checksum" of the DNA string, and is damaged instruct the cell to repair its DNA or undergo apoptosis.
The damage to the p53 can, amongst other things, be caused by disease.
This is my sig. There are many like it but this one is mine. My sig is my best friend. It is my life.
This doesn't really make sense to me. I had been taught that coral reefs required the photosynthesis of the Zooanthelae algae which therefore, restricted such reefs to shallow waters where sunlight could penetrate. This article is talking about coral reefs 2,000 to 3,000 feet deep! That makes no sense.
For those that don't know, sunlight doesn't penetrate into the depths. It is noticeably dimmer at 120 feet (an approximate limit for sport SCUBA divers.) and it is quite dark at 300 feet. No light whatsoever reaches 2,000 feet or deeper.
Further investigation shows that the originally discovery was coral reefs 200-300 feet down which, while quite deep for coral, is far above the darkness of 2,000 feet.
FTA "the Miami researchers believe this is the first time an AUV has been used to map deepwater coral reefs". Seems they never use Google.

It makes sense really. Since we've cutting all the rainforests down to grow soya, we can no longer draw upon the most widely used source of drug inventions. Over 25% of modern drugs contain chemicals originally discovered in rainforest plants & animals. These discoveries then normally allow synthetic mass-production.
Once the rainforests are gone, discovering these chemicals and constituants will get much tougher and many drugs simply wont be invented. Reefs may help produce some drugs, but the article ignores the fact that the diminishing rainforests and other similar natural sources provide far better places to look for potential drug ingredients!
A friend of mine with a biology background took a job involving searching for new plants and herbs with potential scientific/medical uses. He was sent on expensive trips to remote parts of Africa and other locations to examine the plants and flowers - and after years of it, found absolutely nothing useful. Did this mean he was a "failure" or lost his job over it? Heck no... That was pretty much what they *expected* would happen. It's just that there's so much money involved if someone DOES hit upon a useful one, they'll throw wads of money at the problem.
This strikes me as the same thing, only in the ocean rather than on land. Exploring is all well and good, but if there's sufficient risk of doing major damage to the landscape - it seems like the negatives outweigh the lottery-winning like chances of finding a benefit from it.
Stimutax anyone?
Actually, you'd be surprised. Nothing gets into your cells and screws up your DNA like a virus.
Have you heard of HPV (Human Papilloma Virus)? It's a very-common (family) of sexually-transmitted viruses. We've known for a long time that certain types of HPV are the cause of cervical and ovarian cancer in women and testicular cancer in men (e.g.: these cancers are STDs), and more recent research has shown that HPV is also linked to certain forms of skin cancer.
In other words: Yes, cancer can be and often is caused by infectious diseases!
I read State of Fear (Michael Crighton) a while ago. Good book. I don't remember it word for word, obviously, but it seems like it fits.
Agree with Crighton or not, he cites his sources in the book, which is more than I can say for most of the GW scaremongering I've ever seen. Usually it's just "[experts|scientists] [say|warn]", which bothers the shit out of me.
Although it may seem that if a promising drug is found in a deep sea organism, the rapacious drug companies will get all Constant Gardener on them and start the dredging, that is not how it goes. If a compound is isolated from a sponge that had some desirable bioactivity in humans, that compound is isolated and its stucture is determined. Now the reason this compound has some activity in humans - a species the sponge has had no evolutionary contact with - is most usually due to the way some corner of the chemical sticks into a receptor or enzyme in the mammalian cell. This corner, by no means the whole thing, is called a pharmaphore - the actual working part of the molecule. The rest of the compound is unnecessary. The drug company doesn't need to waste money making that part, or squeezing out gallons of sponge juice. They set their hundreds of medicinal chemists to work preparing a simpler, easier to manufacure, compound that contains the necessary pharmaphore.

The DiscoveryHD channel has a program, "Predators of the Great Barrier Reef" which shows a natural enemy to the worlds reef population, the Crown Of Thorns Starfish. These starfish are demolishing the reefs at a very fast rate. During the show, they discuss the fact that certain sea animals (fish, eels, sea-snakes) have venom which can help with pain management and possibly cure some illnesses. http://dhd.discovery.com/tvlistings/episode.jsp?ep isode=0&cpi=110507&gid=0&channel=DHD
Isn't this known as a "fishing expedition"?
Why are they searching for meds there?
Why not search the Sahara desert or the
moon or the African jungle or something?
Why the deep sea reef?

In all seriousness I feel totally out of the loop on global warming, but Al Gore's scaremongering movie makes me think the current attitude is exaggerated. I believe that there is truth to global warming, but I am starting to disbelieve anything that threatens impending doom (this includes terrorism).

I read speculation that fungus develops anti-microbial toxins because it competes with bacteria for living space.
Soooo... in addition to searching deep sea reefs, how about putting various kinds of cancer cells into competition with fungi and bacteria until some develop randomly that kill the cancer. Then see what they did to achieve that.
It might be cheaper.

reminds me of a night dive on scubacat i was leading in thailand at the similan islands, i had a group of 5 with me, i found 1 tea spoon, some rubbish and 1 bottle of jhonny walker blacklabel 12yr in box which couldn't have been more than 2 hours old underwater, of course i was really removing rubbish!
For a moment, I thought that said "A primary goal of the upcoming expedition... will be to search for marine orgasms..."
I was much more interested in the article until I re-read that sentence.

The scientists probably just want to study it just for the sake of studying it (we know very little about the deep seas, and discover on average 2 new species with EVERY dive), but no one gives you money to do that. Having a better "purpose" (i.e. economically viable) may be the only way to get funding.
What is amazing is that even as modern man harvests his latest wonder drugs from the environment, he simultaneously wrecks it by (1) dumping chemicals into the seas, (2) burning the rain forests, etc.
One of the key forces spurring the destruction of the environment is population growth. Expanding populations need living space: in a battle between human population and mother nature, the human population always wins. Indeed, Consider the recent attempt to add immigration-control to the platform of the Sierra Club: immigration-control would curb the population growth of the United States. The attempt completely failed because no one cares about the environmental destruction that population growth facilitates.
To quote a cliched phrase, "the earth does not belong to man; man belongs to the earth." Wrecking the earth is equivalent to long-term suicide.

In other news, cleaning my counter with bleach could kill microbes which produce the cure for obsessive compulsive disorder.
There are unumerable (well, we'll call it 10^30 or something) chemicals being produced by organisms in the world. It hardly matters if the cure for cancer is hiding in a slime mold under a rock, because it's more likely a synthetic cure would be invented before we find cures in the wilderness.
Latewire
If you want to find a treatment for obsessive compulsive disorder, you need to find what causes it. An enzyme for example. You would then need to find a small molecule that interacts with that molecule. You create an assay where you can detect changes in the enzyme, and then you add small drug-like molecules to the assay. This will help you determine what interacts and what could become a drug.
You could theoretically make every single small molecule that is drug sized and use it for the assay. The problem is that you would need more matter than is contained in the universe to create just one of every molecule. You need a starting point. Nature is the starting point. Organisms create molecules to defend themselves, interact with the environment, etc. Billions of years of evolution has allowed for optimization of these interactions.
Medicinal chemists need something to start with and nature often provides the answer.

Synthetic drugs don't just get made. 95% of the time they are modelled on naturally produced sources, they can then get made artifically once the source process has been well researched.
...with rainforests gone, wonder-drug's will be A LOT harder to discover. That is my point!
Your kitchen surface is not likely to produce chemicals useful for drugs either mainly because their not surviving in a niche enviroment. Rainforests for example contain lots of good candidate chemicals because trillions of different types of organisms live in often carefully etched out niche's where funky chemical processes allow them to survive predators. These funky processes are the ones BY FAR most likely to produce "wonder-drugs" if they can be made to do funky stuff in humans aswell.
I noticed the wiki article on Taxol doesn't mention that Bristol-Myers Squibb paid the NCI, National Institute of Cancer, less than the NCI spent developing Taxol. Having paid little for the rights to exclusive use of the Taxol data, MBS has made billions of dollars off of Taxol.

I find it surprising, though, that both syntheses came out of academic labs - not from the pharmaceutical companies that sell the drugs. You'd think they'd have enormous incentive, and more than enough resources, to do such work themselves. If they aren't interested in actually making drugs, what exactly is it that they do?
It's cheaper for the pharmaceutical companies to let government and univserities to do the research then to come in and buy the drug. Taxol, a cancer drug previously mentioned, is a good example. Bristel-Meyer Squibb, who has exclusive rights to the data gathered by the National cancer Institute (NCI), paid the NCI less than half the cost NCI paid to develop Taxol from the Pacific Yew tree. The additional money BMS has spent on it has been in reducing their own costs of producing Taxol. The cost for one cancer treatment with Taxol cost several thousand dollars yet BMS's cost is less than $100. And Taxol has made $billions for BMS.
FalconShould there be a Law?
Your entire fifth paragraph falls apart logically. Use the northwestern yew as an example. Extremely rare species which supplies a useful anticancer compound. Were they harvested to extinction? No. Were they replaced by other yews from around the world? No. Why? It is that species which has the compound. Your paragraph falls apart historically. Which, ironically, is the very rational you use to promote it. Odd, that.
Actually a species of the yew tree has been found to at least augment if not replace the Pacific Yew tree as a source for Taxol. Researchers at FSU found a Yew tree native to the area that can be used to manufacture Taxol.

The Sierra Club did the right thing in opposing immmigration control. For anyone who's against immigration I have one question and depending on what the answer to it is then maybe a second. First, what Native Amwerican Indian Tribe are they from? If they aren't NDN then what tribe signed their or their ancestors who immigrated to America documents? White Northern Europeans invaded and colonized the Americas and now the descendents of those who came to the USA want to prevent anyone else from immigrating here as well.

Ah, Key Largo's an excellent place for scuba diving. While it's not done in the Keys now, dynamite fishing is done frequently in the Indian Ocean. That and the use of cyanide. Shark finning is also popular, especially for shark fin soup.
