AIM OF THE STUDY Kynurenine pathway (KP) is a major route of the tryptophan (TRP) catabolism. In the present study, TRP and KP metabolites concentrations were measured in plasma from rats, pigs and humans after cardiac arrest (CA) in order to assess KP activation and its potential role in post-resuscitation outcome. METHODS Plasma was obtained from: (A)(More)
The phosphatidylinositol-3-kinase (PI3K)/Akt/mTOR pathway is a major target for cancer therapy. As a strategy to induce the maximal inhibition of this pathway in cancer cells, we combined allosteric mTOR inhibitors (rapamycin and RAD001) with a dual PI3K/mTOR kinase inhibitor (PI-103). Both in vitro and in vivo, the combination exhibited more activity than(More)
In non-small-cell lung cancer (NSCLC), one-fifth of patients have KRAS mutations, which are considered a negative predictive factor to first-line therapy. Evidence is emerging that not all KRAS mutations have the same biological activities and possible remodeling of cell metabolism by KRAS activation might complicate the scenario. An open question is(More)
Septic shock remains a major problem in Intensive Care Unit, with high lethality and high-risk second lines treatments. In this preliminary retrospective investigation we examined plasma metabolome and clinical features in a subset of 20 patients with severe septic shock (SOFA score >8), enrolled in the multicenter Albumin Italian Outcome Sepsis study(More)
Recent studies showed that food-contaminant non-dioxin-like polychlorinated biphenyls (NDL-PCBs) congeners (PCB52, PCB138, PCB180) have neurotoxic potential, but the cellular and molecular mechanisms underlying neuronal damage are not entirely known. The aim of this study was to assess whether in-vitro exposure to NDL-PCBs may alter the proteome profile of(More)
OBJECTIVES To define the features of human amniotic mesenchymal stromal cell secretome and its protective properties in experimental models of acute brain injury. DESIGN Prospective experimental study. SETTING Laboratory research. SUBJECTS C57Bl/6 mice. INTERVENTIONS Mice subjected to sham or traumatic brain injury by controlled cortical impact(More)
Large vein endothelium plays important roles in clinical diseases such as chronic venous disease (CVD) and thrombosis; thus to characterize CVD vein endothelial cells (VEC) has a strategic role in identifying specific therapeutic targets. On these bases we evaluated the effect of the natural anti-inflammatory compounds α-Lipoic acid and Ginkgoselect(More)
The anti-leukemic activity of the mitochondria-targeting small molecule sodium dichloroacetate (DCA), used alone and in association with the small molecule inhibitor of the p53/MDM2 interaction Nutlin-3, was analyzed in primary B-chronic lymphocytic leukemia (B-CLL) samples (n=22), normal peripheral blood cells (n=10) and in p53wild-type EHEB, JVM-2, JVM-3(More)
B-chronic lymphocytic leukemia (B-CLL) patients harboring p53 mutations are invariably refractory to therapies based on purine analogues and have limited treatment options and poor survival. Having recently demonstrated that the mitochondria-targeting small molecule sodium dichloroacetate (DCA) exhibits anti-leukemic activity in p53wild-type B-CLL cells,(More)
