Cancer Resistant Mouse Provides Possible Cure 364

Posted by ScuttleMonkey
from the one-of-many-recent-possibilities dept.
Evoluder writes to tell us that scientists at Wake Forest University have found a "cancer resistant mouse" and bred it to make a small army of cancer resistant mice. When transplanting blood from one of these mice to a normal non-resistant mouse they are able to provide "lifetime cancer protection". From the article: "The cancer-resistant mice all stem from a single mouse discovered in 1999. "The cancer resistance trait so far has been passed to more than 2,000 descendants in 14 generations," said Cui, associate professor of pathology. It also has been bred into three additional mouse strains. About 40 percent of each generation inherits the protection from cancer."

    The media is quick to call things like this a cure. The fact remains that, with some exceptions, men are not mice. Back in the late 90s, angiogenesis inhibitors (a class of drugs that inhibit the growth of new blood vessels, needed by tumors to provide nourishment as they grow) were being tested with amazing success in mice, preventing the spread of almost every form of cancer. It was hailed as the coming cure.

    Some angiogenesis inhibitors have proven to be very helpful in treating cancer, but they are not a cure. They aren't nearly as effective in humans as they were in mice, it appears.

    I'm always skeptical (and you should be too), when you hear about something that isn't even in clinical trials, as a possible cure for some disease people get. People simply don't respond the same as mice.

    That said, this does look promising as an avenue, but I wouldn't go out and take up smoking just yet.

      People simply don't respond the same as mice.

      I have always held the same skepticism with regard to studies like these as reported by the media for this very reason. What I always wonder about is how many things we miss because mice (or rabbits, or monkeys, etc.) don't respond to them but humans would. I don't know if there is any good answer to this, because we don't want to start testing random crap all willy-nilly on humans, but sometimes I just wonder if we've already passed up that miracle cure.

      Perhaps someday we'll have powerful enough computers that we can simulate everything, including synthesis of a new drug for your specific form of cancer that your body will respond to. Of course, 'perhaps someday' will probably be long after I die of whatever cancer I'm going to get.

        It's possible that a cure is out there in some plant in the Amazon, or as some bacteria found at the bottom of oceans. But there is no "one" cure for cancer. Cancer works in various ways which means there are various ways to kill it. Pharmacology has come a long way in the past 30 years. These days, it's very targetted. You pick a way you want to attack the cancer, and then you create a drug that does it.

        For example, there's a protein called Vascular Endothelial Growth Factor (VEGF). Cancer causes the release of VEGF around the tumor that in turn, mediates the growth of new blood vessels around the tumor allowing it to get nourishment and grow. So there are several manners that you can try to prevent this. One manner is to try to prevent the creation and release of VEGF in the first place. Another is that you can "competitively inhibit" VEGF by creating a protein that "looks" like VEGF and binds where VEGF normally binds and causes blood vessel growth, except that your particular strain of protein doesn't actually trigger the growth. But by binding where VEGF normally does, you're inhibiting the VEGF from being able to bind and eventually it will be disposed of.

        There are other proteins involved in cancer and other drugs are involved with these proteins. So there are a variety of ways of attacking cancers. The most amazing work along these lines has taken place in the last decade and it's getting better all the time. I suspect it won't be long (a few decades maybe) before cancer is a thing of the past.

      Part of the problem may be the difference in lifetimes between mice and humans, as well as problems in detecting small tumors.

      Anti-angiogenic therapy leads to a hypoxic tumor microenvironment (the tissue surrounding the tumor), which can, in turn, lead a tumor to fragment into smaller tumors. (This has been predicted in mathematical/computer models and verified in some experiments and clinical evidence.)

      In a mouse, those small tumors may not have time to grow large enough to detect, whereas in a human, those fragments have more time to do so, leading to recurrence. Or the small tumors may preferentially grow away from the low-O2/low-glucose region to invade nearby tissues.

      Other, slow time-scale interactions may also not come into play for short mouse lifespans but may be important on human lifespans.

      Of course, the genetic differences are there, too. The problems with the mouse model have always been interesting. -- Paul

    Okay, let's think about this for a second.

    A cancerous cell is one that doesn't know when to quit. It is outside the normal cell cycle, and not listening to every cell's built in death trigger. Forvige my lack of specific biology terminalogy.

    So these mice are "cancer-resistant"? When exposed to carcenigous, do they ignore them? When exposed to massive ammounts of UV light, do they tan but not burn? Do they burn but not get skin cancer? If you clogged thier lungs with cig smoke, would they develop a cough but not cancer?

    How the frak does this work? Are the little mice cells just really tuned into thier death trigger? When a cell mutates enough that it doesn't listen to it's death trigger, it is a cancer. Are these mice just impervious to cell mutation?

    If so, wouldn't that make them an evolutionary dead end? Cancer, while bad, is a by-product of evolution. If cells weren't allowed to ever mutate again, would that spell the end of mice evolution? And if we impart that "cancer-immunity" to we humans, would that spell the end of evolution?

    By all means, someone correct what I have wrong. Biology was never my strong suit. (Nor is spelling)

      It's all in the title of the article... The white blood cells "recognize specific patterns on the cancer cell surface", and flag/attack them as they would any other foreign body. Biology wasn't my strong-suit either, but I would venture a guess that by knowing what sort of mechanism would lead to the white blood cells identifying cancerous/precancerous cells as a risk, the response could be adapted to work similarly (if not identically) in humans. Cancer is not a by-product of evolution, it is a result of malfunctioning cells which replicate uncontrollably. This is generally not a product of 'evolution' as you and I would think of it, but by some sort of damage to the cell which caused it to malfunction. It isn't so much a "death trigger" as replicating without purpose; when you no longer need skin cells at a certain location, and some mutated cell keeps replicating malfunctioning cells, you've got cancer. If your immune system cannot recognize something as a threat, it cannot respond to it, which appears to be the current predicament with cancer in humans.
      • Cancer is not a by-product of evolution

        True, although locally (at a tissue level), cancer is very much like natural selection: the failure to respond to inhibitory signals (via apoptosis), as well as uncontrolled replication give the cancerous cells a relative survival advantage or fitness over normal cells. In fact, this is how many cellular automata models model the spread of mutations through a tissue, even in tissues that maintain a constant cell population.

        Natural selection is particularly usefu

      • I disagree with you a little bit - mainly because I've read about what scientists think caused traits to "appear" in some creatures, like a third eye or something. Basically, something went crazy in the creatures cells, causing a break in or mutation in DNA, which then caused the new growth or whatever the case may be. As a result, this mutated creature was able to do something better than the rest of it's generation, and as a result lived longer, bred, and then passed the trait on. So, I do think Cancer

        Although I do wonder- could you inject a cancer into a human tissue sample? Such as a small skin graft? If so, there might be a humane way to test for immunities, if you could find possible resistant families and get a volunteer.

The "cancer resistance" trait is heritable, so it can ultimately be mapped to specific gene(s) -- that is the most exciting finding, along with the fact that the physiological effect has already been mapped to white blood cells. This way, when the gene is discovered, both the mechanism of cancer resistance and the genetic basis for it will be readily discernable.

    As exciting as this sounds, it's probably not going to lead to a pancea for cancer in humans. We've cured cancer in mice several times over since the 70s. The problem is that mice are a short-lived species that has very little innate resistance to cancer. After all evolution is not going to have an organism waste lots of energy repairing DNA damage and having pools of immune cells constantly checking for mutant cells if the organism is just going to get eaten by a cat in an average of a few months after birth.
        By contrast, humans are a very long-lived animal species. Our bodies already have a large number of cancer-prevention mechanisms that simply aren't present in mice. Take for example telomeres. The telomere ends of chromosomes shorten with each cell replication other than gamete formation. All your cells have what is known as the 'Hayflick limit' where the telomeres get too short, the chromosomes become unstable and the cell dies. Although this mechanism is probably one of the contributors to human aging, it also does a very good job of eliminating many tumors. Most of your tumors hit the Hayflick limit and simply die off before they can present a threat to you. Virtually all human cancers either mutate so as to find a way to reactivate the telomerase that re-lengthens the telomeres or manages to find a way to preserve their telomere ends through chromosomal recombination. Mouse cells, by way of contrast, have huge telomeres which never get short enough to act as this sort of cancer-prevention mechanism.
        As a result human tumors are much 'tougher' than mouse tumors. The average mouse tumor wouldn't stand a chance in a human. Any tumor that manages to thrive in a human has had to jump a host of hurdles and checkpoints that no mouse tumor does in order to simply survive.
        The problem is that many of these cancer cures in mice already exist in humans naturally. Some of these cures (such as this one, most likely) are simply reactivation of vestigial anti-cancer systems in the mice that have atrophied for the above-mentioned reasons. Others are cancer treatments that attack weaknesses in mouse tumors that are simply irrelevant in human ones. I suspect that this super mouse is simply being more human with regards to cancer and that the end result is that we'll rediscover something our bodies already do.
