This study is part of a long term study on a male rat model of peripubertal stress in the Laboratory of Behavioural Genetics that shows increase aggressive behaviours against their partners. We are using here these rats in order to create a female rat mode ...
An emerging concept in cell signaling is the natural role of reactive oxygen species such as hydrogen peroxide (H2O2) as beneficial messengers in redox signaling pathways. The nature of H2O2 signaling is confounded, however, by difficulties in tracking it ...
Retroviruses are both powerful evolutionary forces and dangerous threats to genome integrity. As such, they have imposed strong selective pressure on their hosts, notably triggering the emergence of restriction factors, such as TRIM5alpha, that act as pote ...
The serum-amyloid-P-component-like pentraxin from Limulus polyphemus, a recently discovered pentraxin species and important effector protein of the hemolymph immune system, displays two distinct doubly stacked cyclic molecular aggregations, heptameric and ...
[...] This report presents novel data following the discovery of somatic mutations in the heterotrimeric G protein alpha q subunit (GNAQ), found in 44% of uveal melanomas, 83% of blue nevi, and 50% of melanomas arising within blue nevi. [... click on "Down ...
Many macromolecules in the cell function by forming multi-component assemblies. We have applied the technique of small angle neutron scattering to study a nucleic acid-protein complex and a multi-protein complex. The results illustrate the versatility and ...
Central to the biological function of microtubules. is their ability to modify their length which occurs by addition and removal of subunits at the ends of the polymer, both in vivo and in vitro. This dynamic behavior is strongly influenced by temperature. ...
TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...
Transcriptional activity relies on coregulators that modify chromatin structure or serve as bridging factors between transcription factors and the basal transcription machinery. We identified a new coregulator of peroxisome proliferator-activated receptor ...
The epithelial sodium channel (ENaC) is composed of three homologous subunits: alpha, beta, and gamma. Mutations in the Scnn1b and Scnn1g genes, which encode the beta and the gamma subunits of ENaC, cause a severe form of hypertension (Liddle syndrome). Th ...
