Publication date: Available online 17 October 2019Source: Journal of Molecular BiologyAuthor(s): Rebekah Tillotson, Adrian BirdAbstractMeCP2 is a reader of the DNA methylome that occupies a large proportion of the genome due to its high abundance and the frequency of its target sites. It has been the subject of extensive study due to its link with ‘MECP2-related disorders’, of which Rett syndrome is the most prevalent. This review integrates evidence from patient mutation data with results of experimental studies using mouse models, cell lines and in vitro systems to critically evaluate our understanding of MeC...

Abstract Rett syndrome (RTT) is a leading cause of severe intellectual disability in females, caused by de novo loss-of function mutations in the X-linked methyl-CpG binding protein 2 (MECP2). To better investigate RTT disease progression/pathogenesis animal models of Mecp2 deficiency have been developed. Here, Mecp2 mouse models are employed to investigate the role of protein patterns in RTT. A proteome analysis was carried out in brain tissue from i) Mecp2 deficient mice at the pre-symptomatic and symptomatic stages and, ii) mice in which the disease phenotype was reversed by Mecp2 reactivation. Several proteins...

Conclusions:Regarding patients with RS referred to the sleep medicine clinic, snoring and witnessed apneas were the most common presenting complaints. In addition to breathing abnormalities during wake, OSA was very common in our cohort. Further studies are needed to examine the pathogenesis of OSA in RS and relationships between disease genotype and respiratory abnormality phenotype.Citation:Sarber KM, Howard JJM, Dye TJ, Pascoe JE, Simakajornboon N. Sleep-disordered breathing in pediatric patients with rett syndrome.J Clin Sleep Med. 2019;15(10):1451–1457.

Conclusions: The results indicate that individuals with Rett syndrome can adapt their kinematic gait patterns in response to increasing treadmill speed, but only within a narrow range of speeds. We suggest that treadmill training for ambulatory individuals with Rett syndrome may promote improved walking kinematics and possibly provide overall health benefits. Implications for rehabilitation Walking is an activity that can counter the negative impacts of the sedentary lifestyle of many individuals with disabilities, including those individuals with Rett syndrome. Documentation of the lower limb kinematic patterns displayed ...

This study presents the spectrum of MECP2 mutations in 50 Egyptian RTT females with identified gene mutation. Molecular analysis was carried out by direct sequencing of the gene coding region, followed by multiplex ligation-dependent probe amplification (MLPA) for patients without detected pathogenic variation. In total, 23 different disease-causing mutations, including 5 novel frameshift mutations, have been reported. In the study cohort, T158 M is the most common mutation (18%), followed by R270X (14%). Large rearrangements account for 10% of cases intensifying the emergency of gene quantitative analysis. This study pr...

Abstract Nutritional supplements are traditionally employed for overall health and for managing some health conditions, although controversies are found concerning the role of antioxidants-mediated benefits in vivo. Consistently with its critical role in systemic redox buffering, red blood cell (RBC) is recognized as a biologically relevant target to investigate the effects of oxidative stress. In RBC, reduction of the ATP levels and adenylate energy charge brings to disturbance in intracellular redox status. In the present work, several popular antioxidant supplements were orally administrated to healthy adults a...

RTT patients show multisystem disturbances associated with an oxinflammatory status. Inflammasomes are multi-protein complexes, responsible for host immune responses against pathogen infections and redox-related cellular stress. Assembly of NLRP3/ASC inflammasome triggers ...
