Study of the cytolethal distending toxin (CDT)-activated cell cycle checkpoint. Involvement of the CHK2 kinase.
2001
AbstractThe bacterial cytolethal distending toxin (CDT) triggers a G2/M cell cycle arrest in eukaryotic cells by inhibiting the CDC25C phosphatase-dependent CDK1 dephosphorylation and activation. We report that upon CDT treatment CDC25C is fully sequestered in the cytoplasmic compartment, an effect that is reminiscent of DNA damage-dependent checkpoint activation. We show that the checkpoint kinase CHK2, an upstream regulator of CDC25C, is phosphorylated and activated after CDT treatment. In contrast to what is observed with other DNA damaging agents, we demonstrate that the activation of CHK2 can only take place during S-phase. Use of wortmannin and caffeine suggests that this effect is no…
STUDIO E VALIDAZIONE DI SISTEMI PER L’IDENTIFICAZIONE E IL MONITORAGGIO DI PARAMETRI BIOMEDICI ATTI ALLA PREVENZIONE DI EVENTI INDESIDERATI E ALL’ASS…
L’aumento delle patologie cronico-degenerative nella popolazione mondiale ha comportato un numero sempre maggiore di individui richiedenti assistenza sanitaria, generando, nell’ambito delle realtà ospedaliere, diverse problematiche relative al miglioramento della qualità di vita dei pazienti, ai costi e alla gestione di un numero sempre crescente di soggetti ammalati. Il trattamento sanitario e la ricerca di base si sono pertanto orientati verso la prevenzione delle condizioni che predispongono i soggetti ai peggioramenti clinici e ai ricoveri ospedalieri, puntando sia su nuovi sistemi indossabili di monitoraggio per individuare precocemente i segni di peggioramento, sia su sistemi che poss…
Design and manufacturing feasibility of ITER TBM Frame and Dummy TBMs
2016
Abstract The operation and test of mock-ups of tritium breeding blankets relevant for a future commercial reactor is one of the goals of the ITER machine. To accomplish this goal, mock-ups of breeding blankets, called Test Blanket Modules (TBMs), are installed in three ITER equatorial ports. Each TBM and the associated shield form a TBM-set that is mechanically attached to a steel frame called TBM Frame. A Frame and two TBM-Sets form a TBM Port Plug (TBM PP). The ITER Organization is responsible for the design and manufacture of the TBM Frames and of the Dummy TBMs that could replace the TBM-sets in case they were not available. This paper describes the recent results of the design supporti…
THE MARKET FOR ALTERNATIVE SPECIES OF SHRIMP (PARAPENEUS LONGIROSTRIS) MINIMALLY PROCESSED TO INCREAS THE SHELF LIFE
2012
A reason that has put at the center of attention the crustaceans has been the growing demand for fast food products to which these fishes are particularly suitable. This paper proposes for the first time the use of the species of shrimp Parapeneus longirostris of the Mediterranean sea to realize precooked trays of V range and analyze the evolution of the process of melanosis with respect to commercial products in general coming from the Atlantic Ocean.
Modulation of the hepatic fatty acid pool in peroxisomal 3-ketoacyl-CoA thiolase B-null mice exposed to the selective PPARalpha agonist Wy14,643
2009
10 pages; International audience; The peroxisomal 3-ketoacyl-CoA thiolase B (Thb) gene was previously identified as a direct target gene of PPARalpha, a nuclear hormone receptor activated by hypolipidemic fibrate drugs. To better understand the role of ThB in hepatic lipid metabolism in mice, Sv129 wild-type and Thb null mice were fed or not the selective PPARalpha agonist Wy14,643 (Wy). Here, it is shown that in contrast to some other mouse models deficient for peroxisomal enzymes, the hepatic PPARalpha signaling cascade in Thb null mice was normal under regular conditions. It is of interest that the hypotriglyceridemic action of Wy was reduced in Thb null mice underlining the conclusion t…
The nuclear receptor PPARγ selectively inhibits Th17 differentiation in a T cell–intrinsic fashion and suppresses CNS autoimmunity
2009
T helper cells secreting interleukin (IL)-17 (Th17 cells) play a crucial role in autoimmune diseases like multiple sclerosis (MS). Th17 differentiation, which is induced by a combination of transforming growth factor (TGF)-beta/IL-6 or IL-21, requires expression of the transcription factor retinoic acid receptor-related orphan receptor gamma t (ROR gamma t). We identify the nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR gamma) as a key negative regulator of human and mouse Th17 differentiation. PPAR gamma activation in CD4(+) T cells selectively suppressed Th17 differentiation, but not differentiation into Th1, Th2, or regulatory T cells. Control of Th17 differentia…
