Recently, we reported that human neuroglobin (NGB) is a new player in the signal transduction pathways that lead to 17β-estradiol (E2)-induced neuron survival. Indeed, E2 induces in neuron mitochondria the enhancement of NGB level, which in turn impairs the activation of a pro-apoptotic cascade. Nowadays, the existence of a similar pathway activated by E2(More)
17β-Estradiol (E2) exerts neurotrophic and neuroprotective functions in the brain. Here, E2-induced increased levels of huntingtin (HTT), a protein involved in several crucial neuronal functions is reported. E2 physiological concentrations up-regulate HTT in hippocampus and striatum of rats as well as in human neuroblastoma cells. This effect requires both(More)
In 2000, the third member of the globin family was discovered in human and mouse brain and named neuroglobin (Ngb). Ngb is a monomeric 3/3 globin structurally similar to myoglobin and to the α- and β-chains of hemoglobin, however it displays a bis-histidyl six-coordinate heme-Fe atom. Therefore, ligand binding to the Ngb metal center is limited from the(More)
Among several mechanisms underlying the well-known trophic and protective effects of 17β-estradiol (E2) in the brain, we recently reported that E2 induces the up-regulation of two anti-apoptotic and neuroprotectant proteins: huntingtin (HTT) and neuroglobin (NGB). Here, we investigate the role of this up-regulation. The obtained results indicate that E2(More)
