Monica Coenraads, vice president of research for RSRF and Craig Robertson, executive director of RSRF were in attendance to bring us up to date on RSRF development and research.
Craig explained that RSRF's mission is very focused. It is to fund, promote and accelerate biomedical research for the treatment and cure of Rett syndrome. 2.6 million dollars was raised in 2004 by RSRF. 90% of this was used for research, 5.3% for scientific meetings and 4.7% on education. Since 1999, 6.5 Million dollars in research has been funded. In 2004, the New England area raised $670,000 for RSRF. 75% of this money is from special events.
RSRF, IRSA and the National Institute of Health (NIH) have recently joined in some collaborative efforts to advance Rett research.
There are now four research focus areas. These include replacing neuronal MECP2 through gene therapy, activating silent MECP2 on inactive sites, and defining cell populations that are effected by MECP2 deficiency. The functions of MECP2 are believed to be (1) a role in gene expression; turns downstream genes off (ex. BDNF and DLX5), (2) facilitates 3D folding of DNA into nucleus, (3) strengthens connections between brain cells aiding synaptic plasticity. Current estimates are that there are presently 15,000 Rett cases in the United States and 331,000 world wide. This is based on 1 in 10,000 female births. Rett is considered the leading genetic cause of severe impairment in girls. Mutations in MECP2 have been found in some cases of autism, schizophrenia, learning disabilities and Angelman syndrome. Of the autism spectrum disorders, only Rett syndrome is known to have a genetic cause. The annual RSRF meeting will be held in Chicago in June for three days, chaired by Drs. Bird and Zoghbi.

Dr. Genevieve Laforet, M.D., Ph.D. spoke to us about her ongoing research at University of Massachusetts Medical School in Worcester. Her research is funded by RSRF. RSAM is her research sponsor. Dr. Laforet is looking at theophylline, a drug used to treat asthma, and its potential in correcting neurochemical problems in Rett syndrome. When theophylline is applied to isolated mouse neurons in a petri dish, the desired effect of increased HDAC activity was seen. The next step was to try to see the effect of theophylline on HDAC stimulation in live mice. HDAC is a protein and Dr. Laforet explains in her abstract, "If there were some way to stimulate these HDAC's directly, we could bypass the MeCP2 malfunction and potentially prevent or reduce the severity of RTT." Mice received the drug theophylline either in their drinking water or in time released pellets. After two and a half weeks the mice brains are harvested. It was found that the drug does get into the brain. A 15% increase in HDAC activity was seen in brains of mice receiving the pellets. Therefore the drug is getting into the brain and yielding the desired biochemical change. The effective dosage of the drug must be determined and the window of time when the drug should be given. Next, Dr. Laforet wants to try the drug with MeCP2 deficient mice. Dr. Laforet spoke about some of the characteristics of MeCP2 deficient mice. MeCP2 deficient mice are lacking the typical social interactions seen in mice. They also function differently in maze studies. MeCP2 deficient mice also seem to have an abnormal sleep-wake cycle. Changes in these characteristics can be used to assess the effect of the drug under study. It was also noted that MeCP2 mice are generally smaller and more aggressive than normal mice. Dr. Laforet presented additional information on her experimental work and on her experiences breeding MeCP2 deficient mice. Following the presentation there was a question and answer session.
******************
The evening's program was a presentation by the parents of four women with Rett syndrome. They presented information related to their daughters' out of home placements. Each family has a daughter who is now over twenty-two and is in a living situation outside the family home.
