New drug cures mice of Down Syndrome in a single dose

With one dose, the brains of the mice grew normally and those mice showed learning abilities like that of their un-affected peers.

There has been good news in medicine recently. Not only is there a vaccine to prevent HIV/AIDS in the works, but scientists at John Hopkins University and the National Institutes of Health have also recently used a new drug to cure Down Syndrome in baby mice with just one dose. And although the drug has not yet been tested on humans, it still qualifies as an amazing achievement.

For decades scientists have known that people with Down syndrome, who have an extra copy of chromosome 21, get certain types of cancer at dramatically lower rates than normal. Now, partly by using stem cells derived from the skin of an individual with Down syndrome, researchers at Children’s Hospital Boston have pinpointed the gene that appears to underlie the cancer-protective effect.

Data they analyzed from more than 33,000 American children showed that the older the man when a child is conceived, the lower a child’s score is likely to be on tests of concentration, memory, reasoning and reading skills, at least through age 7.
