Functional characterization of the TERRA transcriptome at damaged telomeres

Joachim Lingner, Jacques Rougemont, Antonio Porro, Sascha Feuerhahn

Telomere deprotection occurs during tumorigenesis and aging upon telomere shortening or loss of the telomeric shelterin component TRF2. Deprotected telomeres undergo changes in chromatin structure and elicit a DNA damage response (DDR) that leads to cellul ...

Survivability of integrated PVDF film sensors to accelerated ageing conditions in aeronautical/aerospace structures

Joël Cugnoni, Alain Schorderet, Enrique René Guzman Solares

This work validates the use of integrated polyvinylidene fluoride (PVDF) film sensors for dynamic testing, even after being subjected to UV-thermo-hygro-mechanical accelerated ageing conditions. The verification of PVDF sensors' survivability in these envi ...

Role of the FoxO3a Transcription Factor in alpha-synuclein Induced Neurodegeneration

Emilda Pino

Increased expression of α-synuclein and point mutations in its amino acid sequence play a causative role in familial forms of Parkinson's disease (PD). In addition, circumstances affecting the level of α-synuclein expression significantly increase the risk ...

Accelerated ageing and degradation in poly-L-lactide/hydroxyapatite nanocomposites

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

Dry, compression molded films of medical grade poly-L-lactide (PLLA) showed a marked reduction in tensile strength and strain after accelerated ageing in aqueous NaOH at 50 degrees C. accompanied by mass loss, surface erosion, increased hydrophilicity and, ...

Calorie Restriction-like Effects of 30 Days of Resveratrol Supplementation on Energy Metabolism and Metabolic Profile in Obese Humans

Johan Auwerx, Richardus Houtkooper, Dongryeol Ryu

Resveratrol is a natural compound that affects energy metabolism and mitochondrial function and serves as a calorie restriction mimetic, at least in animal models of obesity. Here, we treated 11 healthy, obese men with placebo and 150 mg/day resveratrol (r ...

Telomere dysfunction induces environmental alterations limiting hematopoietic stem cell function and engraftment

Cell-intrinsic checkpoints limit the proliferative capacity of primary cells in response to telomere dysfunction. It is not known, however, whether telomere dysfunction contributes to cell-extrinsic alterations that impair stem cell function and organ home ...

Human telomerase RNA accumulation in cajal bodies facilitates telomerase recruitment to telomeres and telomere elongation

Joachim Lingner, Katarzyna Sikora

Telomerase is required for telomere maintenance and is responsible for the immortal phenotype of cancer cells. How telomerase is assembled and reaches telomeres in the context of nuclear architecture is not understood. Recently, the telomerase RNA subunit ...

Telomere length homeostasis requires that telomerase levels are limiting

Joachim Lingner

Stabilization of telomere length in germline and highly proliferative human cells is required for long-term survival and for the immortal phenotype of cancer-derived cells. This is achieved through expression of telomerase reverse transcriptase (TERT), whi ...
