Neurotrophins protect neurons against glutamate and oxidative stress, but the underlying mechanism remains unclear. We investigated the neuroprotective role of the neurotrophin brain-derived neurotrophic factor (BDNF) in neuronal cultures subjected to NMDA or H(2)O(2) toxicity and analyzed the molecular mechanisms involved, particularly those related to(More)
Amyotrophic lateral sclerosis (ALS) is a progressive, lethal, degenerative disorder of motor neurons. The causes of most cases of ALS are as yet undefined. In a previous study, it was shown that N-methyl-D-aspartate (NMDA) and H(2)O(2) stimuli reduce neuronal survival in cortical neurons in culture (Boutahar et al., 2008). To identify variations in gene(More)
Oxidative stress and excitotoxicity are both involved in the pathogenesis of neuronal degenerative diseases like ALS. In order to compare their action, some key proteins involved in their respective signaling pathways, particularly ERK and p53, were analyzed in primary cultures of cortical neurons subjected to NMDA or H(2)O(2) treatment. Early ERK(More)
We show that expression of p57(Kip2), a potent tight-binding inhibitor of several G(1) cyclin-cyclin-dependent kinase (Cdk) complexes, increases markedly during C2C12 myoblast differentiation. We examined the effect of p57(Kip2) on the activity of the transcription factor MyoD. In transient transfection assays, transcriptional transactivation of the mouse(More)
BACKGROUND Immunological mechanisms are suspected in sensory neuropathy (SN) occurring with systemic autoimmune diseases and in some idiopathic cases, but so far there are no antibodies (Abs) identifying these neuropathies. METHODS In the search for such specific antibodies, serum samples were collected from 106 patients with SN of these 72 fulfilled the(More)
