Brain volume loss evident before symptoms in Rett mouse models

Mice in Rett syndrome models showed a loss of brain volume before disease symptoms were evident, with brain shrinkage worsening over time, an MRI study showed. Delays in brain growth were observed in these mice, and brain growth stopped and appeared to reverse in older female Rett mice. Because…

Omega-3 Fatty Acid Seen to Restore Energy to Brain Cells Lacking MeCP2

Treatment with omega-3 fatty acid restored the function of mitochondria, the production centers of cellular energy, in brain cells called astrocytes lacking MeCP2 — the key protein in most cases of Rett syndrome, a study reported. The study, “Docosahexaenoic acid increased MeCP2 mediated…

Acadia, Stoke Team Up in $60M Deal to Develop RNA-based Therapies

Acadia Pharmaceuticals and Stoke Therapeutics are teaming up to develop and commercialize new RNA-based therapies — using Stoke’s proprietary research platform, TANGO — for the potential treatment of Rett syndrome. As part of the collaboration, Stoke will receive a $60 million upfront payment from Acadia. “Stoke’s…

Rett Protein’s Loss Tied to Premature Closing of Brain Plasticity Window

The lack of a working MeCP2 protein — the most common cause of Rett syndrome — prematurely closes a window of neuronal plasticity in a brain region involved in social memory, a study showed. Neuronal plasticity is the brain’s ability to re-wire itself, to strengthen or weaken its neuronal connections, in response…

Early Treatment Reverses Cell Defects, Improves Survival in Mice

Early administration of a compound intended to enhance signals between brain cells lessened disease severity, and improved overall health and survival in a mouse model of Rett syndrome. The improvements, which also included benefits in nerve cell activity, indicate that treatments enhancing neuronal activity early…

‘Band of Mothers’ Connect to Raise Awareness About Boys With Rett

Of the people who know about Rett syndrome, many think it affects only females. But families of boys with this disorder know differently. Parents of children with an ultra-rare manifestation of this already rare and little-known disease find each other online and grow close in this…

Stem Cells of Rett Mice Prone to Arrested Growth, Less Able to Produce Energy, Study Shows

Loss of MECP2, the defective protein in most people with Rett syndrome, induces premature growth arrest of bone marrow stem cells — known as senescence — and limits their energy production, according to a mouse study. These biological alterations may underlie the development of the disease, the researchers…
