Drug Reverses Retardation In Mice

Posted by kdawson on Fri Jun 27, 2008 08:33 AM
from the give-my-regards-to-algernon dept.
snydeq writes "Rapamycin, a medication doctors prescribe to transplant patients to prevent organ rejection, has been used to reverse learning disorders and mild retardation associated with TSC (tuberous sclerosis complex) in mice. Because the condition is linked to autism, scientists believe the drug may be used to treat learning disabilities and short-term memory deficits in all kinds of autism as well. The scientists chose rapamycin after they realized the drug regulates one of the same proteins that the TSC gene does, just in different parts of the body. 'What was surprising is that we could give rapamycin to adult mice and reverse their condition,' said neurobiologist Alcino Silva of the David Geffen School of Medicine at UCLA. 'We did not know ... that this drug would be equally effective for the learning disabilities as it is for tissue rejection.' Rapamycin treatment leveled the playing field between normal and TSC mice in as little as three days."

        Uhm, wrong. Both parties consist mostly of criminals (lobbying = corruption, even if by the book it is legal). And both parties vote against public good. The populicrats just prefer the copyright mafia, robbing taxpayers and so on.

        The few honest politicians can be found in both parties.

        I'm a Republican, a Bush and now McCain supporter, and have more troll points on slashdot to prove my right wing cred, and I don't find this offensive at all. Come on people, lighten up. This was -funny-. If I would have been first to the joke, I would have made the same crack going the other way. The more seriously we take our political affiliations, the more we are trapped into the political parties that really don't represent us!

        After all, can't we say: "Christ, Bush is such a great oil man, that he goes and invades the world's largest untapped source of oil, and now gas is $5 / gallon."

      Sadly, it won't work. Although you were joking, I uncharacteristically jumped straight to TFA on this one, as my oldest daughter's IQ measures at 65. That's about five points lower than Forest Gump, if I remember the movie correctly.

      Sadly, this treatment only fights Darwin. TFA says

      Scientists used rapamycin--a medication doctors prescribe to patients who have had transplants to prevent their bodies from rejecting the new organs--to treat learning disorders associated with a disease called tuberous sclerosis complex (TSC) in mice. TSC is a rare genetic disorder that causes brain tumors, seizures, learning disabilities, skin lesions and kidney tumors in the 50,000 Americans and one million people worldwide who have the disease.

      A million people might not seem rare, but consider that there are six billion people on the planet. From a link from TFA:

      What is Tuberous Sclerosis?

      Tuberous sclerosis (TSC) is a rare genetic disease that causes benign tumors to grow in the brain and on other vital organs such as the kidneys, heart, eyes, lungs, and skin. It commonly affects the central nervous system. In addition to the benign tumors that frequently occur in TSC, other common symptoms include seizures, mental retardation, behavior problems, and skin abnormalities. TSC may be present at birth, but signs of the disorder can be subtle and full symptoms may take some time to develop. Three types of brain tumors are associated with TSC: cortical tubers, which generally form on the surface of the brain; subependymal nodules, which form in the walls of the ventricles (the fluid-filled cavities of the brain); and giant-cell astrocytomas, a type of tumor that can block the flow of fluids within the brain.

      Most mental retardation is caused by injury.

      A bit offtopic, but the US public school system, bad as it is for average (IQ 100) kids, it fails miserably for both "special" and "gifted" students; my youngest's IQ is 131 and she wound up dropping out (later getting her GED and now manages a GameStop store at age 21) while the oldest graduated high school an got her diploma but lives on SSI disability.

      The US public school system is badly broken.

    ...let me say that any hope is a good hope. This condition is a far, far greater burden than you probably realize, and to date most of medical science is still groping in the dark.

    My son's neurologist actually prescribed an anti-psychotic to a three-year-old boy. One that, by the way, had NEVER been tested on children and was not FDA approved for that purpose.

    There are some voodoo-science options as well. Some work all the time for certain cases, while others do not work at all. Gluten-free/Casen-free diet, Omega3's, Anti-Fungals etc, etc, etc. If you take information like this to a practicing MD they are quite likely to either roll their eyes our laugh outright. Still, there are those that swear by them.

    This is where we presently sit.

    Imagine having a young man, totally dependent on you, who is struggling not only to fit in, but to avoid punishment for perfectly natural behaviors. Now imagine the feeling when the realization sets in that you simply will not ever be able to 'fix' him, no matter how much parenting you may apply. In fact, try though you do, at the end of the day it feels like no one has helped him at all.

    Any hope is a good hope.

      Amen to that - I'm looking forward to taking my severely autistic stepson out to the Brooklands Double Twelve this Sunday, and will be taking the utmost pleasure from seeing him enjoy himself among all the old racing cars.

      The behavioural problems we can cope with, but he's physically handicapped as well, so in residential care.

      1K to turn someone into a productive member of society and lead a meaningful life? It's a bargain. We're paying more than that to keep rapists alive in jails. Not to mention that as technology moves on it will either cost less or new drug will take it's place being either more effective or less expensive.

          Look at you. Sitting there, presumably in full control of your faculties, able to socialize, to date, to start and raise a family, to use your time as you wish, to banter back and forth on websites, or read a book, to build a career and take pride in your accomplishments, to further your education and expand your horizons.

          Do you even KNOW anybody who suffers from any of these mild-to-mid-grade mental deficiencies? And I don't mean know OF, I mean KNOW and care for?

          If you did, you'd see very clearly the tragedy that is a person who much of the time seems completely healthy and normal.

          Wouldn't it be GREAT if pharma would give these things away for free? Sure. But this world today is not perfect. And you can't expect just a single industry to "disarm" and go socialized. Even if it WOULD benefit us all.

          There's a test you can apply here: When a pharma company spends $1bn researching a drug that ends-up a flop, should we as taxpayers refund that cash to them? If the answer is "no," then you can't begrudge them for taking profits where they can.

          And as much as I hate paying $4 for gas, I could say the same about oil: I don't know about you, but 8, 9 years ago when gas was $0.85/gallon, I never decided to pay $1.50 just to help out. Oil companies collapsed and consolodated when Oil was $20/barrel and now, I can't begrudge them for taking profits where they can.

          Remember, nearly all of us are shareholders in these companies, whether directly, thru a 401k, thru a pension, thru a union, thru your local government which often invests a portion of its cash-on-hand, etc.

          So the drug costs $1k. That's the reality of it. To suggest that being a "slave to the pharma industry" is as bad as being a prisoner of your own reduced faculties shows an abject lack of understanding, not to mention, a serious empathy deficit.
