Drug Reverses Retardation In Mice 318

Posted by kdawson 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."

      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.

      • Quick search of AutismSpeaks.org for TSC turned up this:

        Tuberous Sclerosis
        Individuals with Tuberous Sclerosis (TS) suffer from learning and behavioral deficits akin to those observed in autism as well as epilepsy. In TS, depending on the study, up to 60% of patients also meet the diagnostic criteria for autism. The defective genes are TSC1 (hamartin) and TSC2 (tuberin) which normally function in a complex of molecules important in cell growth and division. The complex is a suppressor of mTOR signaling. The link to autism turns out to be the PTEN molecule, which similarly functions as a suppressor of mTOR signaling. Some individuals with autism have been found to have mutations in the PTEN gene. Mice deficient in the mouse PTEN gene display autism-like behaviors, as do mice that have low levels of TSC1 and TSC2. Importantly, there is a drug that can function like PTEN, TSC1 and TSC2 in suppressing mTOR -- rapamycin. In the animal models, rapamycin normalizes learning deficits and reverses some of the abnormal phenotypes. Therefore, rapamycin is undergoing clinical trials to determine whether it can be an effective medication to alleviate the symptoms of TS. (Drs. Alcino Silva, Kevin Ess and Luis Parada)
