(Submitter supplied) Rett syndrome is a severe neurodevelopmental disorder caused by loss-of-function mutations in the methyl-CpG-binding protein gene, MECP2. MeCP2 is a methyl-cytosine binding protein that is proposed to function as a transcriptional repressor. However, multiple gene expression studies comparing wild-type and MeCP2-deficient neurons have failed to identify gene expression changes consistent with loss of a classical transcriptional repressor. more...

(Submitter supplied) In order to identify some lncRNA potentially involved in Rett syndrome we performed a mouse lncRNA expression microarray on whole brain samples coming from wild-type and MeCP2 Knock-out littermates. We found 2 lncRNAs directly bound by MeCP2 and upregulated in KO samples. We then focused on AK081227 because it overlaps with Gabrr2. The expression of this GABA receptor and the overlapping AK081227 are inversely correlated in thalamus, suggesting the long non-coding is regulating his own host.

(Submitter supplied) The postnatal neurodevelopmental disorder Rett syndrome (RTT) is caused by mutations in the gene encoding Methyl-CpG-binding Protein 2 (MeCP2). Despite decades of research, it remains unclear how MeCP2 actually regulates transcription or why RTT features appear only 6-18 months after birth. We examined MeCP2 binding to methylated cytosine in the CH context (mCH, where H = A, C, or T) in the adult mouse brain and found that MeCP2 binds these mCH sites, influencing nucleosome positioning and transcription. more...

(Submitter supplied) We report the application of single molecule-based sequencing technology for high-throughput genom-wide mapping of MeCP2 binding and DNA methylation in mouse brain and cerebellum respectively. We find a good correlation between MeCP2 occupancy and methyl-CpG density and depletion of MeCP2 binding at CpG Islands, the majority of which are constitutively hypomethylated. This study provides a comprehensive characterisation of the genome wide distribution of MeCP2.

(Submitter supplied) Background. Rett syndrome (RTT) is a complex neurodevelopmental disorder that is one of the most frequent causes of mental retardation in women. A great landmark in research in this field was the discovery of a relationship between the disease and the presence of mutations in the gene that codes for the methyl-CpG binding protein 2 (MeCP2). Currently, MeCP2 is thought to act as a transcriptional repressor that couples DNA methylation and transcriptional silencing. more...

(Submitter supplied) Rett syndrome (RTT) is a neurodevelopmental disorder characterized by developmental regression around 6-18 months after birth, followed by a lifetime of intellectual disability, stereotyped behaviors, and motor deficits. RTT is caused by mutations in MeCP2, a methyl-CpG binding protein that was traditionally believed to repress gene expression. Gene expression studies of individual brain regions, however, have revealed that MeCP2 loss-of-function leads to the subtle activation and repression of its gene targets. more...

(Submitter supplied) Rett syndrome (RTT) is one of the most prevalent female mental disorders. De novo mutations in methyl CpG binding protein 2 (MeCP2) are a major cause of RTT. MeCP2 regulates gene expression as a transcription regulator as well as through long-range chromatin interaction. Because MeCP2 is present on the X chromosome, RTT is manifested in a X-linked dominant manner. Investigation using murine MeCP2 null models and post-mortem human brain tissues has contributed to understanding the molecular and physiological function of MeCP2. more...

(Submitter supplied) Disruption of the MECP2 gene leads to Rett syndrome (RTT), a severe neurological disorder with features of autism. MECP2 encodes a methyl-DNA-binding protein that is proposed to function as a transcriptional repressor, but, despite numerous studies examining neuronal gene expression in MeCP2 mutants, no coherent model has emerged for how MeCP2 regulates transcription. Here we identify a genome-wide length-dependent increase in the expression of long genes in neurons lacking MeCP2. more...

(Submitter supplied) Mutations in MECP2 cause the autism-spectrum disorder Rett syndrome. MeCP2 is predicted to bind to methylated promoters and silence transcription. However, the first large-scale mapping of neuronal MeCP2-binding sites on 26.3 Mb of imprinted and nonimprinted loci revealed that 59% of MeCP2-binding sites are outside of genes and that only 6% are in CpG islands. Integrated genome-wide promoter analysis of MeCP2 binding, CpG methylation, and gene expression revealed that 63% of MeCP2-bound promoters are actively expressed and that only 6% are highly methylated. more...
