Modulating protein ubiquitination via proteasome inhibition represents a promising target for cancer therapy, because of the higher sensitivity of cancer cells to the cytotoxic effects of proteasome inhibition. Here we show that CEP-18770 is a novel orally-active inhibitor of the chymotrypsin-like activity of the proteasome that down-modulates the nuclear(More)
The most abundant populations of non-neoplastic cells in the glioblastoma (GBM) microenvironment are resident microglia, macrophages and infiltrating monocytes from the blood circulation. The mechanisms by which monocytes infiltrate into GBM, their fate following infiltration, and their role in GBM growth are not known. Here we tested the hypothesis that(More)
It is generally assumed that about half of the neurons produced during neurogenesis die before completion of maturation of the central nervous system (CNS). Neural cell death is also relevant in aging and several neurodegenerative diseases. Among the modalities by which neurons die, apoptosis has very much attracted the interest of investigators because in(More)
PURPOSE To unravel the regulatory network underlying nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) -mediated lymphomagenesis of anaplastic large-cell lymphoma (ALCL) and to discover diagnostic genomic classifiers for the recognition of patients with ALK-positive and ALK-negative ALCL among T-cell non-Hodgkin's lymphoma (T-NHL).

There is a general agreement on the Nestin re-expression in reactive astrocytes, but its modalities differ among experimental animal species and between the latter and human material. In a series of 40 surgical specimens, including gliomas, vascular malformations, abscesses and angiomas, the glial reaction has been studied by immunohistochemistry and(More)
Nestin is a marker of early stages of neurocytogenesis. It has been studied in 50 neuroepithelial tumors, mostly gliomas of different malignancy grades, by immunohistochemistry, immunofluorescence, immunoblotting, and confocal microscopy and compared with GFAP and Vimentin. As an early marker of differentiation, Nestin is almost not expressed in diffuse(More)
In response to neurodegeneration, the adult mammalian brain activates a cellular cascade that results in reactive astrogliosis and microgliosis. The mechanism through which astrocytes become reactive and the physiological consequences of their activation in response to neurodegeneration is complex. While the activation and proliferation of astrocytes has(More)
Glioblastoma is the most common and most aggressive primary brain tumour. Standard of care consists of surgical resection followed by radiotherapy and concomitant and maintenance temozolomide (temozolomide/radiotherapy→temozolomide). Corticosteroids are commonly used perioperatively to control cerebral oedema and are frequently continued throughout(More)
We have used the mammalian post-natal cerebellar cortex as a model to dissect out the molecular morphology of neuronal apoptosis in a well-defined population of central neurons: the cerebellar granule cells. By immunocytochemistry, in situ labeling of apoptotic cells, and analysis of cerebellar slices following particle-mediated gene transfer (biolistics),(More)
γ-Aminobutyric acid is the principal inhibitory neurotransmitter in adults, acting through ionotropic chloride-permeable GABAA receptors (GABAARs), and metabotropic GABABRs coupled to calcium or potassium channels, and cyclic AMP signalling. During early development, γ-aminobutyric acid is the main neurotransmitter and is not hyperpolarizing, as GABAAR(More)
