RADX: A novel single-stranded DNA-binding protein regulating telomere recombination

Telomeres are specialized nucleoprotein structures present at the ends of linear chromosome. The telomeric DNA part is comprised of 5-15 kilo base pairs of double stranded TTAGGG repeats and it contains at the 3' end a single-stranded G-rich overhang of 50 ...

Differential regulation of RNA polymerase III genes during liver regeneration

Felix Naef, Philippe Jacquet, Nicolas Jean Philippe Guex, Jonathan Aryeh Sobel, Cristian Carmeli, Olivier Martin, Irina Krier, Mauro Delorenzi, Nouria Hernandez, Bart Deplancke, Jacques Rougemont, François Mange, Laura Symul, Fabrice David, Sunil Kumar Raghav, Julien Delafontaine, Marion Leleu, Julia Catharina Cajan, Winship Herr, Kyle Gustafson, Maykel Lopes, Dominic Villeneuve, Ioannis Xenarios

Mouse liver regeneration after partial hepatectomy involves cells in the remaining tissue synchronously entering the cell division cycle. We have used this system and H3K4me3, Pol II and Pol III profiling to characterize adaptations in Pol III transcriptio ...

CSL controls telomere maintenance and genome stability in human dermal fibroblasts

Joachim Lingner, Paris Jafari, Thomas Frédéric Lunardi

Genomic instability is a hallmark of cancer. Whether it also occurs in Cancer Associated Fibroblasts (CAFs) remains to be carefully investigated. Loss of CSL/RBP-J kappa, the effector of canonical NOTCH signaling with intrinsic transcription repressive fun ...

Infrared nanospectroscopic mapping of a single metaphase chromosome

Andrzej Kulik, Giovanni Dietler, Francesco Simone Ruggeri, Ewelina Wioletta Lipiec

The integrity of the chromatin structure is essential to every process occurring within eukaryotic nuclei. However, there are no reliable tools to decipher the molecular composition of metaphase chromosomes. Here, we have applied infrared nanospectroscopy ...

Exploring on Protein-DNA interactions

Alexandra Styliani Kalantzi

A variety of DNA-binding proteins organizes the chromosomal DNA and regulates gene transcription, and DNA replication and recombination. In particular, for gene regulation there is a category of DNA-binding proteins, the transcription factors, which can de ...

Vertical Ionization Energies and Electron Affinities of Native and Damaged DNA Bases, Nucleotides, and Pairs from Density Functional Theory Calculations: Model Assessment and Implications for DNA Damage Recognition and Repair

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis

To assess the effect of an 8-oxoguanine (8OG) defect base on the vertical ionization energies (VIEs) and electron affinities (VEAs) of DNA, density functional theory calculations were carried out for native and defect DNA bases and nucleotides, as well as ...

The yeast C/D box snoRNA U14 adopts a "weak" K-turn like conformation recognized by the Snu13 core protein in solution

Benjamin Marcel Daniel Rothé

Non-coding RNAs associate with proteins to form ribonucleoproteins (RNPs), such as ribosome, box C/D snoRNPs, H/ACA snoRNPs, ribonuclease P, telomerase and spliceosome to ensure cell viability. The assembly of these RNA-protein complexes relies on the abil ...

The telomeric DNA damage response: Insights into telomere compaction and identification of novel damage signaling factors

Aleksandra Vancevska

Telomeres are dynamic nucleo-protein structures capping the ends of all eukaryotic chromosomes. Together with telomerase, they counteract replication-dependent telomere attrition. Additionally, they disguise the linear ends of the chromosome from the DNA d ...

Modeling and analysis of parts and devices of genetic regulation

Yves Berset

DNA encrypts the composition of the cellular material that is synthesized through transcription and translation. Never-theless, gene regulation mechanisms determine the final amount of transcribed and translated material. Transcription factors (TF) are a c ...

A practical qPCR approach to detect TERRA, the elusive telomeric repeat-containing RNA

Joachim Lingner, Marianna Feretzaki

Telomeres, the heterochromatic structures that protect the ends of the chromosomes, are transcribed into a class of long non-coding RNAs, telomeric repeat-containing RNAs (TERRA), whose transcriptional regulation and functions are not well understood. The ...
