Mitochondrial dysfunction and cytosolic redox imbalance in Rett syndrome

Reference: Michael Müller Abstract: Rett patients and mouse models of Rett syndrome, i.e. mice carrying mutations in the gene coding for the transcriptional regulator MeCP2, suffer from highly irregular breathing with temporary arrest of breathing, which gives rise to repeated episodes of reduced systemic oxygen supply (hypoxia). Yet, instead of desensitization or neuronal adaptation to … Read more

Replication and translation of epigenetic information

Reference: SPP 1129 Abstract: Methyl-cytosine binding proteins (MeCPs) play a central role in the mediation of epigenetic effects. They bind to methylated sites in the DNA, recruit histone deacetylases (HDACs9 which may then cause chromatin condensation and transcriptional silencing. We have previously studied the dynamics of DNA replication in living mammalian cells using fluorescence labeling … Read more
