Drug Turns Immune System Against All Tumor Types
sciencehabit writes, quoting an article in Science: "A single drug can shrink or cure human breast, ovary, colon, bladder, brain, liver, and prostate tumors that have been transplanted into mice, researchers have found. The treatment, an antibody that blocks a 'do not eat' signal normally displayed on tumor cells, coaxes the immune system to destroy the cancer cells."
The abstract and full paper are freely available. It seems fairly promising: "In mice given human bladder cancer tumors, for example, 10 of 10 untreated mice had cancer that spread to their lymph nodes. Only one of 10 mice treated with anti-CD47 had a lymph node with signs of cancer. Moreover, the implanted tumor often got smaller after treatment — colon cancers transplanted into the mice shrank to less than one-third of their original size, on average. And in five mice with breast cancer tumors, anti-CD47 eliminated all signs of the cancer cells, and the animals remained cancer-free 4 months after the treatment stopped."
It worked even better in mice that didn't get cancer transplants!
I kid, I kid.
"First they came for the slanderers and i said nothing."
What about non-tumor cells, which also display this cell determinant?
...
Nevermind...

What about a treatment developed that coaxes the immune system to destroy useful / healhy / viable cells?
Very promising, but before we uncork the champagne, it's important to keep in mind that mice and humans are different enough that most cures don't translate 1:1 to humans.
It won't fly, as antibodies are cheap and not complicated to do. Seriously, do you really believe Big Pharma is going to let it happen ? A treatment simple like this would jeopardize their business, risking billions of dollar. They'll do something to stop this treatment in its tracks. They always do. Sound paranoid ? I wish. It's more like realistic. Their purpose is not really to cure cancer, but getting a maximum profit from it.
And the most one quoted researcher can say is that the results are "promising?" Anyone else get these sense that these "cancer researchers" don't like the idea of the end of their job security and having to find a new line of work?
I propose to perform the next experiment on /b/.
Then maybe we will be able to continue this thread there.
Contrary to the popular belief, there indeed is no God.
I'm a little over 30 now. Me getting cancer is relatively probable at some point in my life. The big question is will they cure it first?
Oh, and if cancer doesn't get me, will I have robot attendants at home when I'm old and fragile, or will they just upgrade my body? Medicine is progressing at an amazing rate, really...

I'm not sure why some people are so sure "big pharma" are disinterested in curing many diseases/conditions. After all, if you can sell a cure for cancer, you just landed in a bucket of money.
Beyond that, the need for a cure is overwhelming. Even corporate greed will often take a backseat because this issue affects us all. If it was a condition associated with a specific population, or with the poor etc then I'm sure the interest would be much less humanitarian.
Every day we get closer to a cure, every piece of research, even if it's only effective on mice takes us when step closer. I for one, appreciate every effort made in this regard.
I do not have cancer and no one close to me has it either. Perhaps just a matter of time.
If the our world have this drugs, humanity will be saved. Please visit my homepage : http://www.thanhlapdoanhnghiepvn.net/
IANAMD but, note it says mice, and it might substitute chronic autoimmune disease for the cancer. But combining an anti CD47 drug with a system for making alerting the immune system to the cancer, e.g. Dendrons Provenge, ought to make immune threapy a high sucessful care. Without targeting the immune system on
a particular organ, an autoimmune response, could do mass long term damage, (long term isn't something we worry about in mice). A 90% cure rate is great through, modern cancer drugs have been getting approved for 30% cure rates or lower.
How do we make it less effective so people have to take it constantly to keep the cancer in check? Where's the profit in a cure we need treatments not cures!
or is it only for the 1%
...If everything goes well. Also, how much it may cost then?
And still, no cure for cancer. ... oh.
What is the normal function of the "do not eat" signal? Just what normal function is going to get messed up when you turn this off?
I'm no expert in these things, but AFAIK the process goes something like this:
Each of these steps can take months. Some of it's political and administrative wrangling, some of it's just that the test itself will take some time before you can be sure of the results. A drug can fail at any one of these stages and it's back to the drawing board (or maybe the test tube).
The whole process takes years. Yet newspapers often start reporting about "miracle cure" drugs that have only just completed the first round of live animal trials. Which is why you hear about all sorts of miracle cures that never see the light of day.
What is the normal function of the "do not eat" signal? Just what normal function is going to get messed up when you turn this off?
I'm not sure which "do not eat" signal they're talking about. But one that I do know a little about is the one that prevents rejection of a placenta and multiple sclerosis.
The immune system apparently recognizes and avoids attacking its own body primarily by:
- Editing the sections of DNA coding for antibodies to produce a bunch of small clones of proto-antibody-producing cells that randomly react to all sorts of stuff.
- Shortly after birth (when most of mommy's random cellular components have been purged from baby's body) letting these clones take a grand tour of baby's body - and anybody who recognizes anything dies off.
- Then the survivors (who don't recognize any tissue in baby) turn themselves on and get ready to do a growth spurt if they recognize a target at the same time they're getting an "I'm being damaged" signal (i.e. histamine).
Result: A no-autoimmune immune system. Well, almost.
A significant problem is that there are a few tissues that aren't deployed yet when the baby is just born. One such tissue is the myelin sheaths of the nerves. Another, of course, is placental tissue from a pregnancy. (Unlike tribbles, humans aren't born pregnant.) If nothing were done about this, the immune system tissues would be a time-bomb, ready to go into attack mode if it happens to see a damage signal near a nerve or a placenta. This would result in multiple sclerosis or spontaneous abortion - both very big negative scores in the evolutionary game. So the immune system has a patch.
The main myelin protein has a short sequence that tells the immune system that this is a late-blooming tissue, so leave it alone. (I'm guessing this may be the "do not eat" signal they're talking about.) Placental tissue has the same sequence. There are lots of opportunities for failure, of course. (Defects in the signal molecules, disease organisms mimicing it, etc.) But when this patch is working right the nerves and a new baby are protected without significantly degrading the immune system's response to diseases.
This, by the way, is the reason nursing on cow's milk is a risk factor for MS. Milk has a protein related to the myelin sheath protein, but with the "do not eat" signal slightly different. As a result a baby may develop an allergy to that component of cow's milk - and thus to the common stretch of the myelin protein. Result: Autoimmune reaction to the myelin sheaths.

http://documentaryheaven.com/cancer-cure-dr-burzynski-therapy/
Documentary on Stanislaw R. Burzynski’s revolutionary cancer cure treatment based on his discovery on the mechanics of cancer, which lead him to the creation of the Antineoplaston Therapy. Dr. Burzynski’s Therapy has successfully cured thousands of terminal cancer patients for the last 30 years and has demonstrated to be 3 to 5 times more effective than the conventional chemotherapy and radiation treatments.
In spite of the success of his therapy, he has faced the prosecution of big pharma and the FDA which has tried to stop his therapy from spreading in the United States.
Thank you for the information.
And we all know how those countries attitudes are towards optional ingredients.
Most here can easily afford brand name medicine. We are the 1%, enjoy it.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
Typically the first testing in humans is done in patients which have already failed multiple therapies (relapse or resistant), eliminating the ethical quandry that they would have had a better response with conventional treatment.
Ban Engadget - moderators censor comments!
And it's also why the researchers are being deliberately cautious about this one.
Will Smith would not endorse this research. Best watch the movie "I am Legend" before getting too excited about this.
8.1 create machines for production / packaging incl. everything on computer systems.
8.2 validate those machine.
8.3 create medicamen with those maschines.
8.4 validate samples for institutes like FDA (these samples have to be created with those maschine to get a licences on markets).
8.5 after inspection and validation of production and packaging process on site successful, start producing and shipping.
All these steps together can take roughly 3 to 5 years in total. So even if 1-7 are successful, they can fail at step 8 or have a LONG (months to years) delay, cause if one of these steps fail, they start @ 8.1 again.
How would Big Pharma ever charge enough for a one-time treatment to cure cancer? Yes, I think this discovery will have to be...studied.... for a lonnnnnnng time, first.*
* Except for Big Pharma execs, their mistresses, and friends.
Typically the first testing done in humans is done to assess the safety of the drug and determine the maximum dosage before bad things happen. The test subjects are all healthy people looking to make 3-10k for a couple weeks of work (lots of college students). They sit around in a clinic for a couple weeks and take increasingly large dosages until they start vomiting or showing other signs of overdose.
Test your idea in a handful of sick humans. If it works better than existing treatments, continue. (This is going to be awkward. Ethical clearance is an important part of any medical testing; there's little chance of getting ethical clearance of using this in place of existing treatments for cancer patients because if it doesn't work, you've delayed them treatment that could have worked. You could possibly use it in conjunction with, or in patients for whom existing treatments haven't worked, but then there's the question of is the treatment more/less effective when the cancer's progressed that far? Or if it's given in conjunction with existing treatments? Sure you can devise tests to deal with these issues, but they won't be as simple as "administer drug, keep a list of who's had it and what the results were".)
There are patients who refuse chemo because they prefer death to the side effects. They would gladly volunteer for an alternative treatment with less extreme side-effects. I have seen my grandmother go through chemo, and I hope I never have to make this decision, but if I were diagnosed with non-operable cancer, I'm not sure I'd opt to be treated. I suppose it would depend on survival chances. 80% survival rate, I'd probably think it's worth a try. 50% survival rate or worse? I'd probably opt to take the time I have left to enjoy life a bit instead of spending it going through the horrors of chemo. No objections to trying a treatment that would still let me enjoy that time, even if it doesn't work.

That's good news for mice! Of course they get free health care. How many people will actually be able to afford such a drug, assuming that it works on people without having major side effects?
Come on!!! Lets get this going, get some human subjects quickly, and lets end cancer as quickly as possible....stop just rehashing stories for the last 3 years about the same thing....I sometimes think that the amount of time it takes to get this out there, is enough tie for all of them to die from the disease....!
I'm totally wasted, can someone do a summary for a drunk person?
Newest generation of consoles; same reasoning.
... be apportioned when there are 44 authors for a single paper? That's not a criticism of this paper or what is hopefully an important discovery but just the whole scientific peer-reviewed system seems in danger of breaking down if this is the norm.
FORGET big Pharma, they are not interested in cures... Google Gerson Therapy, Budwig Protocol (flaxseedoil2 on yahoo groups) , Cellect Powder, Apricot Seeds, Pancreatin.
If cancer is the result of an inherent flaw in the design in the human body then it can still be eradicated by eliminating whatever "flaws" exist in the human body that lead to the development of the disease.
Sure, all you need is omniscience and omnipotence.
The human body is a lot more complicated than a computer program that you can check for infinite loops. Oh, wait, you can't do that, either.
Lots of articles like this come and go. As far as I am concerned it is vaporware until doctors begin prescribing it. Lets hope it does turn out to be all that.
If you're in science just for the credit, you shouldn't be.
If you're in science to provide breakthroughs and build and rely on others work, with the assistance of similar people, then having 44 authors on a paper gives it approximately 44 times more weight than a single name. And you *can* still say "I worked on Project X" when you want to use it as a job-seeking tool. The people who care about that will find out exactly what you did on the project, I assure you.
So much science, nowadays, CANNOT be done by a lone crank working out of a hermit-like existence, especially where it concerns medical trials and sharing information.
In maths, yes, 44 names on a paper would reek of "Put my name on that because I helped you changed the font size", but in medicine? I don't think I'd believe anything without a significant trial and, thus, weight of names behind a paper. But WHO those 44 are matters infinitely more than how many there are.
What is the normal function of the "do not eat" signal? Just what normal function is going to get messed up when you turn this off?
The more important question: how long before manipulating the "do not eat" signal becomes the latest diet drug?
When our name is on the back of your car, we're behind you all the way!
http://science.slashdot.org/story/10/11/29/0410239/aging-reversed-in-mice Not so long ago, Slashdot saw this story on how scientists were able to prevent the splicing of telomeres from chromosomes in mice in order to allow not only prevention of aging, but de-aging. The only problem was that these mice inevitably died from becoming riddled with cancerous tumors. So now that this development has occurred, are we one step closer to having mice that cannot die of natural causes?
Only if one accepts that said god also provided his patients with those lovely stage 4 tumors eating their brains, lungs, etc...
God did not provide the patients with stage 4 tumors. Satan gave them the tumors.
So perhaps you're insinuating that Satan is *your* god?
until our computer systems are sophisticated enough to *accurately* model the effects on humans, we're going to continue to do animal testing. that's just the reality we live in.

Great, now all those social programs that are dependent on most people dying off in their 70s will be even more effed.
One wonders if this kind of treatment/cure (as if cures will be delivered since there's no "planned obsolescence" to encourage future revenues), if it works in humans at all, will end up exacerbating any auto-immune disorders?
Now can we cure stupidity?
Furries make the internet go.
What will Fark do? They'll have to stop using that "... still no cure for cancer" meme. Wonder what'll take its place.
So I guess chemoterapy and radioterapy fail at step 4 or 5.
I have Psioritic Arthritis; my understanding is it's caused by the immune system thinking my skin are joints are cancerous, and so attacking them; that's why the newest treatments are 'tnf' (tumor necrosis factor) blockers, that reduce the immune systems cancer fighting tags.
So, if you have auto-immune disease, these drugs could make your body tear itself apart from the inside, or maybe trigger auto-immune disease where none existed.
But it you're gonna die from cancer otherwise, bring it on.
They turn of the ability for the cell to wave its hand and say, "This is not the cell you are looking for."

Scientists have been able to cure any and all kind of cancer *in mice* since the two statin combo (that was going to cure all cancer) in the late 90s. So tired of these worthless cancer (and whatever else disease) research stories that never go anywhere. There's DRACO for all viruses....yup, cures them all IF you're a mouse. If you're a lab rat, they can help you. You'll see that nothing will come of this and it'll be forgotten in a few months. If the stuff actually worked, they'd supress it or claim the manufacture isn't feasable. Seriously, as long as there's more money in chronic illness and as long as we've got a for profit health care industry, forget any cures...duh.
So we'll see this on the market (for several tens of thousands of dollars per dose so the lawyers get paid) in 60-70 years after the patent disputes are cleared up?
Anecdote:
I ahve watch sone go througbh cancer several time in my life.
Twice in the 1970s
You have cancer, 6 months later dead.
Once in the 80s. Treamentr with horrible side effects. nasty, nasty side effects. Survived for 4 years.
twice again in the 90s:
bad side effects, one died 4 years later, the other is still alive.
My mother in 2010.
Treatment was nasty, but cause early enough and she is still alive. Her cancer is a cancer that only 5% of peopel who get cancer get.
The anecdote is just that, and anecdote, however it does coincide with the constant betterment of treatments. Less harsh, more specific, less amount of time.

You're absolutely right, surviving cancer today is far more likely than even ten years ago, and it's only getting better. Chemo is still a bitch. My grandmother went through it in the late 90's, and did not survive.
I'm glad your mother made it through. The one thing I learned from my experience watching my grandmother is that the people who choose to fight have to be strong and courageous. Going back for another treatment in a week after they've experienced what the first one did to them? Takes a very strong desire to live to make yourself do that. I did not in any way mean to imply people shouldn't choose to fight, or that a cancer diagnosis is a death sentence. Just that the path to becoming a cancer survivor is a tough one, and I'm not sure if I'm personally that tough. Depending on the situation, I might just give up right away and enjoy the time I've got left as much as possible. That said, nothing makes me happier than knowing there are people like your mother out there, who fight it out and beat that damned disease, and I hope the number of survivors keeps going up.

You're right; I don't know much about the Amish. If their shunning of certain kinds of tech doesn't diminish the carcinogen exposure risk associated with modern life, go ahead and correct me; I won't mind.
