Neuroscience, neurology and psychiatry (NEURO) 2006 project�ANR-MeCP2synapse -Study of synaptic and neuronal physiological alterations in the MeCP2 gene deficient animals models of Rett syndrome

by

Reference: ANRn.a.6-NEURn.a.003 Abstract: PROJECT SUMMARY – Scientific Background and Objectives�Mutations in the gene encoding the protein MeCP2, a transcriptional regulator binding methylated DNA, are causing neurological disorders – including Rett syndrome (RTT) – characterized by an apparently brain development normal.�The mice with truncated versions of MeCP2 show similar neurological deficits in patients RTT.�Deficits in dendritic … Read more

Relationships between ghrelin concentration in blood and growth and physical activity in children

by

Reference: ETF6225ﾠ Abstract: The biochemical markers that influence the growth of children have not been investigated much. The main goal of the present study is to investigate the relationships between novel peptide hormone ghrelin and anthropometrical characteristics, body composition, physical activity and aerobic working capacity, also to examine the adaptation to aerobic work and weight … Read more

Increased levels of 4HNE-protein plasma adducts in Rett syndrome.

by

Reference: Abstract: Rett syndrome (RTT) is a neurological disorder and a leading cause of mental retardation in females. It is caused by mutations in methyl-CpG-binding protein 2 (MeCP2) gene and more rarely in cyclin-dependent kinase-like 5 (CDKL5) and forkhead box protein G1 (FOXG1) genes. Increased oxidative stress (OS) has been documented in MeCP2-RTT patients. Here, … Read more

Epigenetic dysfunction of MeCP2 in chronic heart failure (B03)

by

Reference: B03 – Subproject to SFB 992: Medical Epigenetics (MEDEP) From basic mechanisms to clinical applications Abstract: The methyl-CpG-binding protein 2 (MeCP2) detects symmetrically methylated cytosine-guanine sequences (CpG) in the genomic DNA and modulate gene expression by recruiting coactivator and corepressor-proteins.ﾠWe found that MeCP2 is significantly downregulated in hypertrophic and failing heart.ﾠThe functional significance of … Read more

Epigenetics of chronic heart failure

by

Reference: Abstract: The focus of this project are epigenetic mechanisms that underlie the remodeling in the heart in the emergence of hypertrophy and failure and recovery after mechanical unloading.ﾠIn the foreground is the methyl-DNA-binding protein 2 (MeCP2), which specifically recognizes methylated DNA sequences, and thus can modulate gene expression.ﾠIn the continuation phase of this project, … Read more
