APOBEC3G-depleted resting CD4+ T cells remain refractory to HIV1 infection

BACKGROUND: CD4+ T lymphocytes are the primary targets of HIV1 but cannot be infected when fully quiescent, due to a post-entry block preventing the completion of reverse transcription. Chiu et al. recently proposed that this restriction reflects the actio ...

The role of Myc in bone metabolism

Raphaëlle Stuer

Various studies have proven the involvement of Myc in cell growth and proliferation but also cell transformation and tumorigenesis. Since regulation of cell proliferation and differentiation is mandatory in bone metabolism, we investigated the role of Myc ...

Phosphorylation does not prompt, nor prevent, the formation of alpha-synuclein toxic species in a rat model of Parkinson's disease

Michaël Unser, Patrick Aebischer, Bernard Schneider, Daniel Sage, Samareh Azeredo da Silveira Lajaunias

Phosphorylation is involved in numerous neurodegenerative diseases. In particular, alpha-synuclein is extensively phosphorylated in aggregates in patients suffering from synucleinopathies. However, the share of this modification in the events that lead to ...

Cell shape changes indicate a role for extrinsic tensile forces in Drosophila germ-band extension

David Welchman

Drosophila germ-band extension (GBE) is an example of the convergence and extension movements that elongate and narrow embryonic tissues. To understand the collective cell behaviours underlying tissue morphogenesis, we have continuously quantified cell int ...

Spinal Cord Stimulation Restores Locomotion in Animal Models of Parkinson's Disease

Miguel Nicolelis

Dopamine replacement therapy is useful for treating motor symptoms in the early phase of Parkinson's disease, but it is less effective in the long term. Electrical deep-brain stimulation is a valuable complement to pharmacological treatment but involves a ...

Coupling the cell cycle to development

Pierre Gönczy, Yemima Suryani Budirahardja

The core machinery that drives the eukaryotic cell cycle has been thoroughly investigated over the course of the past three decades. It is only more recently, however, that light has been shed on the mechanisms by which elements of this core machinery are ...

Mild hypothermia improves transient gene expression yields several fold in Chinese hamster ovary cells

Florian Maria Wurm, David Hacker, Stéphanie Tissot, Sarah Wulhfard, Sophie Bouchet, Jean Cevey

Large-scale transient gene expression (TGE) in mammalian cells is a rapid method to generate recombinant proteins, but the volumetric productivity for secreted proteins is still more than an order of magnitude lower than the yields typically achieved with ...

The ruthenium(II)-arene compound RAPTA-C induces apoptosis in EAC cells through mitochondrial and p53-JNK pathways

Paul Joseph Dyson, Christian Hartinger

An investigation of the mol. mechanism of the anticancer activity demonstrated by the ruthenium(II)-arene compd. [Ru(η6-p-cymene)Cl2(pta)] (pta is 1,3,5-triaza-7-phosphaadamantane), termed "RAPTA-C", in Ehrlich ascites carcinoma (EAC) bearing mice is descr ...

Characterization and Targeting of Forkhead Box K2 (FOXK2)

Forkhead/winged-helix transcription factors are evolutionarily conserved and found in organisms as diverse as yeast and humans. They regulate a broad spectrum of events during embryonic and post natal development, including cell cycle regulation, survival, ...

Differential requirement for beta-catenin in epithelial and fiber cells during lens development

Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...
