Multimodal transcriptomic atlases of mouse spinal cord injury

Matthieu Pierre Gautier

A spinal cord injury (SCI) triggers a cascade of molecular and cellular responses involving inflammatory cell infiltration and cytokine release, apoptosis, demyelination, excitotoxicity, ischemia, and the formation of a fibrotic scar surrounded by an astro ...

Gene replacement therapy provides benefit in an adult mouse model of Leigh syndrome

Johan Auwerx, Giorgia Benegiamo

Mutations in nuclear-encoded mitochondrial genes are responsible for a broad spectrum of disorders among which Leigh syndrome is the most common in infancy. No effective therapies are available for this severe disease mainly because of the limited capabili ...

Eosinophils regulate adipose tissue inflammation and sustain physical and immunological fitness in old age

Johan Auwerx, Norman Lionel Moullan

Adipose tissue eosinophils (ATEs) are important in the control of obesity-associated inflammation and metabolic disease. However, the way in which ageing impacts the regulatory role of ATEs remains unknown. Here, we show that ATEs undergo major age-related ...

Latest advances in aging research and drug discovery

Andrea Ablasser

An increasing aging population poses a significant challenge to societies worldwide. A better understanding of the molecular, cellular, organ, tissue, physiological, psychological, and even sociological changes that occur with aging is needed in order to t ...

Basic creep of cement paste at early age - the role of cement hydration

Karen Scrivener

In this work, the uniaxial creep in compression during the first days of hydration is studied experimentally on cement pastes with w/c of 0.50. to order to assess the effect of the evolving microstructure on creep, the so-called equivalent systems are empl ...

A three-state model for the regulation of telomerase by TERRA and hnRNPA1

Joachim Lingner, Sophie Redon, Ivo Zemp

Telomeres, the physical ends of eukaryotic chromosomes, are transcribed into telomeric repeat-containing RNA (TERRA), a large non-coding RNA, which forms an integral part of telomeric heterochromatin. In vitro, naked TERRA molecules are efficient inhibitor ...

Telomerase is essential to alleviate pif1-induced replication stress at telomeres

Joachim Lingner

Pif1, an evolutionarily conserved helicase, negatively regulates telomere length by removing telomerase from chromosome ends. Pif1 has also been implicated in DNA replication processes Such as Okazaki fragment maturation and replication fork pausing. We fi ...

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 ...

Delivery of erythropoietin by encapsulated myoblasts in a genetic model of severe anemia

Patrick Aebischer, Bernard Schneider, Nicole Déglon

BACKGROUND: Existing animal models of anemia inadequately reflect the hematocrit usually present in chronic renal failure (CRF) patients and do not permit long-term treatment studies. The transgenic mouse strain 134.3LC (Epo-TAg(H)) displays a severe chron ...
