Epigenetics of the Synapse in Neurodegeneration
Current Neurology and Neuroscience Reports (2019) 19:72 https://doi.org/10.1007/s11910-019-0995-y GENETICS (V. BONIFATI, SECTION EDITOR) Epigenetics of the Synapse in Neurodegeneration Mary Xylaki1 & Benedict Atzler1 & Tiago Fleming Outeiro1,2,3 # The Author(s) 2019 Abstract Purpose of Review In the quest for understanding the pathophysiological processes underlying degeneration of nervous systems, synapses are emerging as sites of great interest as synaptic dysfunction is thought to play a role in the initiation and progression of neuronal loss. In particular, the synapse is an interesting target for the effects of epigenetic mechanisms in neurodegeneration. Here, we review the recent advances on epigenetic mechanisms driving synaptic compromise in major neurodegenerative disorders. Recent Findings Major developments in sequencing technologies enabled the mapping of transcriptomic patterns in human postmortem brain tissues in various neurodegenerative diseases, and also in cell and animal models. These studies helped identify changes in classical neurodegeneration pathways and discover novel targets related to synaptic degeneration. Summary Identifying epigenetic patterns indicative of synaptic defects prior to neuronal degeneration may provide the basis for future breakthroughs in the field of neurodegeneration.

Alexander Flemming, 16672, Vari, Athens, Greece; 4University of York, Department of Biology, Heslington, York, YO10 5DD, United Kingdom The genetic code is an abstraction of how mRNA codons and tRNA anticodons molecularly interact during protein synthesis; the stability and regulation of this interaction remains largely unexplored. Here, we characterized the expression of mRNA and tRNA genes quantitatively at multiple time points in two developing mouse tissues. We dis- covered that mRNA codon pools are highly stable over development and simply reflect the genomic background; in contrast, precise regulation of tRNA gene families is required to create the corresponding tRNA transcriptomes. The dynamic regulation of tRNA genes during development is controlled in order to generate an anticodon pool that closely corresponds to messenger RNAs. Thus, across development, the pools of mRNA codons and tRNA anticodons are invariant and highly correlated, revealing a stable molecular interaction interlocking transcription and translation.

DKFZ Postdoctoral Fellowships 2021 Hosting group information for applicants Name of DKFZ research division/group: Division of Regulatory Genomics and Cancer Evolution (B270) Contact person: Duncan Odom Group homepage: https://www.dkfz.de/en/regulatorische-genomik/index.php Please visit our website for further information on our research and recent publications. RESEARCH PROFILE AND PROJECT TOPICS: Dr Odom’s laboratory studies how genetic sequence information shapes the cell's DNA regulatory landscape and thus the trajectory of cancer genome evolution. Our long-standing interest in interspecies analysis of matched functional genomic data has revealed the extensive and rapid turn-over of tissue-specific transcription factor binding, insulator elements, polymerase occupancies, and enhancer activities during organismal evolution. My laboratory has begun exploiting single-cell RNA-sequencing and large-scale whole genome sequencing in understanding molecular and cancer genome evolution. Recent high-profile studies from the Odom lab used single-cell transcriptional analysis to conclusively demonstrate that ageing results in substantial increases in cell-to-cell transcriptional variability and exploited chemical carcinogenesis in mouse liver to reveal how the persistence of DNA lesions profoundly shapes tumour genomes. First, we are currently interviewing for experimentally focused postdoctoral fellows to spearhead multiple diverse and interdisciplinary collaborations in single-cell analysis, functional genomics, and spatial transcriptomics with Gerstung, Stegle, Hoefer, and Goncalves laboratories at DKFZ. Such an appointment would offer unusual opportunities for an experimentally-focused postdoc to learn and deploy bioinformatics tools in collaboration with one or more world-leading computational biology laboratories. Second, we are seeking a postdoctoral researcher to spearhead a collaboration with Edith Heard's group at EMBL, focused on how X-chromosome dynamics can shape disease susceptibility in older individuals. -

About Microneurotrophins
About MicroNeurotrophins UNLOCKING THE PROMISE OF NEUROTROPHINS Most researchers now agree that ALS and other neurodegenerative diseases including Multiple Sclerosis, Parkinson’s and Alzheimer’s are remarkably complex, almost certainly involving a combination of different biological, genetic and external triggers. Yet, time and again, drug development for these multi-faceted diseases has focused almost exclusively on medications that only target one factor likely causing the disease. It’s not surprising that these single-target drugs have uniformly failed in previous clinical trials. With this in mind, esteemed pharmacologist Dr. Achilleas Gravanis and his team of scientists from Bionature, a spin-off of the University of Crete in Greece, began searching for a way to effectively address the multiple triggers contributing to the onset and progression of neurodegenerative diseases. Their investigation led them to study neurotrophins, proteins naturally secreted in the brain that transmit signals between motor neurons by binding to and activating two different types of receptors, TrkA and p75, found on the surface of nerve cells. Twenty years of research have shown that neurotrophins help motor neurons develop, grow, function, signal and even repair themselves. Neurotrophins also appear to protect motor neurons from stress and death. By contrast, ALS causes motor neurons to degenerate and die and ALS patients experience a profound loss of neurotrophins as the disease progresses. However, numerous clinical trials have been unable to prove the efficacy of neurotrophins to treat ALS and other neurodegenerative diseases. TWO STARTLING DISCOVERIES To understand why, Dr. Gravanis and his colleagues carefully examined past studies on neurotrophins, and two astonishing observations became apparent to them. -

Psychotropic Drug-Induced Genetic- Epigenetic Modulation of CRTC1
Delacrétaz et al. Clinical Epigenetics (2019) 11:198 https://doi.org/10.1186/s13148-019-0792-0 RESEARCH Open Access Psychotropic drug-induced genetic- epigenetic modulation of CRTC1 gene is associated with early weight gain in a prospective study of psychiatric patients Aurélie Delacrétaz1, Anaïs Glatard1, Céline Dubath1, Mehdi Gholam-Rezaee2, Jose Vicente Sanchez-Mut3, Johannes Gräff3, Armin von Gunten4, Philippe Conus5 and Chin B. Eap1,6* Abstract Background: Metabolic side effects induced by psychotropic drugs represent a major health issue in psychiatry. CREB-regulated transcription coactivator 1 (CRTC1) gene plays a major role in the regulation of energy homeostasis and epigenetic mechanisms may explain its association with obesity features previously described in psychiatric patients. This prospective study included 78 patients receiving psychotropic drugs that induce metabolic disturbances, with weight and other metabolic parameters monitored regularly. Methylation levels in 76 CRTC1 probes were assessed before and after 1 month of psychotropic treatment in blood samples. Results: Significant methylation changes were observed in three CRTC1 CpG sites (i.e., cg07015183, cg12034943, and cg 17006757) in patients with early and important weight gain (i.e., equal or higher than 5% after 1 month; FDR p value = 0.02). Multivariable models showed that methylation decrease in cg12034943 was more important in patients with early weight gain (≥ 5%) than in those who did not gain weight (p = 0.01). Further analyses combining genetic and methylation data showed that cg12034943 was significantly associated with early weight gain in patients carrying the G allele of rs4808844A>G (p = 0.03), a SNP associated with this methylation site (p =0.03).
