During the development of the nervous system, after a given number of divisions, progenitors exit the cell cycle and differentiate as neurons or glial cells. Some cells however do not obey this general rule and persist in a progenitor state. These cells, called stem cells, have the ability to self-renew and to generate different lineages. Understanding the(More)
Among the identified risk factors of age-related macular degeneration, sunlight is known to induce cumulative damage to the retina. A photosensitive derivative of the visual pigment, N-retinylidene-N-retinylethanolamine (A2E), may be involved in this phototoxicity. The high energy visible light between 380 nm and 500 nm (blue light) is incriminated. Our aim(More)
An increasing body of evidence indicates that gene expression can be modulated by posttranscriptional mechanisms. RNA binding proteins, for instance, control gene expression at many regulatory levels including RNA splicing, transport, stability, and translation. Although numerous RNA binding proteins have been identified, very few have been studied(More)
In 1970s, taurine deficiency was reported to induce photoreceptor degeneration in cats and rats. Recently, we found that taurine deficiency contributes to the retinal toxicity of vigabatrin, an antiepileptic drug. However, in this toxicity, retinal ganglion cells were degenerating in parallel to cone photoreceptors. The aim of this study was to re-assess a(More)
As highlighted in this review, the phosphoinositide-phospholipase C pathway is strongly implicated in the control of mouse oocyte meiosis. The pathway becomes progressively functional as oocyte growth advances, and it appears to play a role in the G2/M transition when meiosis resumes, at least in the in vitro spontaneous model. Even if the inositol(More)
