Cancer Resistant Mouse Provides Possible Cure 364
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."

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

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?

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.

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.

The other is positional cloning. You basically breed a resistant mouse with a non-resistant mouse to get an F1 intercross. If you are dealing with inbred mice, these are genetically identical but each chromosome is different- one from mom and one from dad. You breed this generation with eachother to get an F2 intercross and then phenotype the offspring (are they resistant to cancer?) and then genotype them (what are their genetic differences?). Genes undergo semi-random reassortment through cross-over events and all offspring in the F2 incross have a random sprinkling of genes from mom and dad. You then do linkage analysis to find out which genetic differences are most closely linked to the phenotype you are looking for.
