Mitochondria are swollen, show altered respiratory rates, and their inner membrane is leaking protons. To advance the understanding of these disturbances and clarify their link to redox impairment and oxidative stress, we assessed mitochondrial respiration in defined brain regions and cardiac tissue of male wildtype (WT) and MeCP2-deficient (Mecp2-/y) mice. Also, we quantified for the first time neuronal redox-balance with subcellular resolution in cytosol and mitochondrial matrix. Quantitative roGFP1 redox imaging revealed more oxidized conditions in the cytosol of Mecp2-/y hippocampal neurons than in WT neurons. Furthermore, cytosol and mitochondria of Mecp2-/y neurons showed exaggerated redox-responses to hypoxia and cell-endogenous reactive oxygen species (ROS) formation. Biochemical analyzes exclude disease-related increases in mitochondrial mass in Mecp2-/y hippocampus and cortex. Protein levels of complex I core constituents were slightly lower in Mecp2-/y hippocampus and cortex than in WT; those of complex V were lower in Mecp2-/y cortex. Respiratory supercomplex-formation did not differ among genotypes. Yet, supplied with the complex II substrate succinate, mitochondria of Mecp2-/y cortex and hippocampus consumed more O2 than WT. Furthermore, mitochondria from Mecp2-/y hippocampus and cortex mediated an enhanced oxidative burden. In conclusion, we further advanced the molecular understanding of mitochondrial dysfunction in RTT. Intensified mitochondrial O2 consumption, increased mitochondrial ROS generation and disturbed redox balance in mitochondria and cytosol may represent a causal chain, which provokes dysregulated proteins, oxidative tissue damage, and contributes to neuronal network dysfunction in RTT."],["dc.identifier.doi","10.3389/fphys.2019.00479"],["dc.identifier.pmid","31114506"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16085"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59907"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/12"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | A06: Mitochondrienfunktion und -umsatz in Synapsen"],["dc.relation.workinggroup","RG Rehling (Mitochondrial Protein Biogenesis)"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","573"],["dc.subject.ddc","612"],["dc.title","Neuronal Redox-Imbalance in Rett Syndrome Affects Mitochondria as Well as Cytosol, and Is Accompanied by Intensified Mitochondrial O2 Consumption and ROS Release"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Such requirements are optimally fulfilled by the incorporation of unnatural amino acids (UAAs) in the proteins of interest (POI), followed by fluorophore conjugation via click chemistry. However, this approach has been limited to single POIs in mammalian cells. Here we solve this problem by incorporating different UAAs in different POIs, which are expressed in independent cell sets. The cells are then fused, thereby combining the different proteins and organelles, and are easily imaged by dual-color super-resolution microscopy. This procedure, which we termed Fuse2Click, is simple, requires only the well-established Amber codon, and allows the use of all previously optimized UAAs and tRNA/RS pairs. This should render it a tool of choice for multi-color click-based imaging."],["dc.identifier.doi","10.1021/acsnano.8b06047"],["dc.identifier.pmid","30525434"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15921"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59757"],["dc.identifier.url","https://sfb1190.med.uni-goettingen.de/production/literature/publications/47"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/2"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/614765/EU//NEUROMOLANATOMY"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/339580/EU//MITRAC"],["dc.relation","SFB 1190: Transportmaschinen und Kontaktstellen zellulärer Kompartimente"],["dc.relation","SFB 1190 | P09: Proteinsortierung in der Synapse: Prinzipien und molekulare Organisation"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | A06: Mitochondrienfunktion und -umsatz in Synapsen"],["dc.relation.issn","1936-086X"],["dc.relation.workinggroup","RG Rehling (Mitochondrial Protein Biogenesis)"],["dc.relation.workinggroup","RG Rizzoli (Quantitative Synaptology in Space and Time)"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","573"],["dc.subject.ddc","612"],["dc.title","Combined Use of Unnatural Amino Acids Enables Dual Color Super-Resolution Imaging of Proteins via Click Chemistry"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Nevertheless, protein lifetimes have been difficult to obtain in vivo. They are readily measured in vitro by feeding cells with isotopically labeled amino acids, followed by mass spectrometry analyses. In vivo proteins are generated from at least two sources: labeled amino acids from the diet, and non-labeled amino acids from the degradation of pre-existing proteins. This renders measurements difficult. Here we solved this problem rigorously with a workflow that combines mouse in vivo isotopic labeling, mass spectrometry, and mathematical modeling. We also established several independent approaches to test and validate the results. This enabled us to measure the accurate lifetimes of ~3500 brain proteins. The high precision of our data provided a large set of biologically significant observations, including pathway-, organelle-, organ-, or cell-specific effects, along with a comprehensive catalog of extremely long-lived proteins (ELLPs)."],["dc.identifier.doi","10.1038/s41467-018-06519-0"],["dc.identifier.pmid","30315172"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15388"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59372"],["dc.identifier.url","https://sfb1190.med.uni-goettingen.de/production/literature/publications/42"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/41"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.intern","In goescholar not merged with http://resolver.sub.uni-goettingen.de/purl?gs-1/15611 but duplicate"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/339580/EU//MITRAC"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/614765/EU//NEUROMOLANATOMY"],["dc.relation","SFB 1190: Transportmaschinen und Kontaktstellen zellulärer Kompartimente"],["dc.relation","SFB 1190 | P09: Proteinsortierung in der Synapse: Prinzipien und molekulare Organisation"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | A03: Dynamische Analyse der Remodellierung der extrazellulären Matrix (ECM) als Mechanismus der Synapsenorganisation und Plastizität"],["dc.relation.issn","2041-1723"],["dc.relation.workinggroup","RG Rehling (Mitochondrial Protein Biogenesis)"],["dc.relation.workinggroup","RG Rizzoli (Quantitative Synaptology in Space and Time)"],["dc.relation.workinggroup","RG Urlaub (Bioanalytische Massenspektrometrie)"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","573"],["dc.subject.ddc","612"],["dc.title","Precisely measured protein lifetimes in the mouse brain reveal differences across tissues and subcellular fractions."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
