Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...

Meeting our Makers:Uncovering the cis-regulatory activity of transposable elements using statistical learning

Cyril David Son-Tuyên Pulver

The adaptation of organisms to their environment depends on the innovative potential inherent to genetic variation. In complex organisms such as mammals, processes like development and immunity require tight gene regulation. Complex forms emerge more often ...

Inhibiting de novo ceramide synthesis restores mitochondrial and protein homeostasis in muscle aging

Johan Auwerx, Xiaoxu Li, Mario Romani, Tanes Imamura de Lima, Sandra Rodriguez Lopez, Jean-David Horacio Morel, Hao Li, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Barbara Moreira Crisol, Changmyung Oh, Dohyun Park

Disruption of mitochondrial function and protein homeostasis plays a central role in aging. However, how these processes interact and what governs their failure in aging remain poorly understood. Here, we showed that cer- amide biosynthesis controls the de ...

RNA-based nanomedicines and their clinical applications

Yi Wang

RNA-based nanomedicines encompass a range of therapeutic approaches that utilize RNA molecules or molecules that target RNAs for the treatment or prevention of diseases. These include antisense oligonucleotides (ASOs), small interfering RNAs (siRNAs), endo ...

Astrocyte-targeting RNA interference against mutated superoxide dismutase 1 induces motoneuron plasticity and protects fast-fatigable motor units in a mouse model of amyotrophic lateral sclerosis

Patrick Aebischer, Bernard Schneider, Nathalie Marie Géraldine Bernard, Cylia Cloé Rochat

In amyotrophic lateral sclerosis (ALS) caused by SOD1 gene mutations, both cell-autonomous and noncell-autonomous mechanisms lead to the selective degeneration of motoneurons (MN). Here, we evaluate the therapeutic potential of gene therapy targeting mutat ...

An integrative approach to elucidate the mechanisms and dynamics of Huntingtin aggregation and inclusion formation in neuronal models of Huntington's Disease

Nathan Alain Denis Riguet

Despite the fact that the gene responsible for Huntington's disease (HD) is known, we still do not understand the underlying mechanisms leading to neurodegeneration and death. Identifying and understanding the mechanisms controlling mutant huntingtin (mHtt ...

Nucleosome Binding by the Lysine Specific Demethylase 1 (LSD1) Enzyme Enables Histone H3 Demethylation

Beat Fierz, Aurore Marie-France Delachat, Abhinav Dhall

The essential human enzyme lysine specific demethylase 1 (LSD1) silences genes by demethylating mono- and dimethylated lysine 4 in histone H3 (H3K4me1/2). Studies of the minimal requirements for LSD1 activity are complicated by the heterogeneity of histone ...

Single-Cell Tracing Dissects Regulation of Maintenance and Inheritance of Transcriptional Reinduction Memory

Sebastian Maerkl, Johannes Becker

Transcriptional memory of gene expression enables adaptation to repeated stimuli across many organisms. However, the regulation and heritability of transcriptional memory in single cells and through divisions remains poorly understood. Here, we combined mi ...

Ultrasensitive quantitative measurement of huntingtin phosphorylation at residue S13

Hilal Lashuel, Lara Petricca, Sean Michael Deguire

Huntington's disease (HD) is a progressive neurodegenerative disorder caused by an expansion of a CAG triplet repeat (encoding for a polyglutamine tract) within the first exon of the huntingtin gene. Expression of the mutant huntingtin (mHTT) protein can r ...

Development of novel methods and tools to decipher the huntingtin post-translation modifications code

Anass Chiki

Huntington's disease (HD) is a fatal genetic neurodegenerative disorder caused by a CAG repeat expansion in the Huntingtin gene of more than 36 repeats. This repeat is translated into a polyglutamine (polyQ) stretch within the first exon-encoded region of ...
