67 [0.52; 0.84], p=0.001), and pH (OR 0.15 [0.02; 1.04], p=0.05). By using a receiver operating characteristic curve analysis, hemoglobin level below 9 g dl-1, fibrinogen level below 2 g l-1, pH below 7.12 and BMI below 25 were identified to predict early major bleeding events. Major bleeding events were independently associated with mortality (OR 2.54, CI 95% [1.38; 4.66], p=0.01). CONCLUSIONS We found that post-cardiotomy VA ECMO, hemoglobin levels below 9 g dl-1, fibrinogen levels below 2 g l-1, pH below 7.12 and BMI below 25 were associated with a higher risk for early major bleeding events. The ELAVL1 (or human antigen R - HuR) RNA binding protein stabilizes the mRNA, with an AU-rich element, of several genes such as growth factors (i.e. VEGF) and inflammatory cytokines (i.e. TNFα). We hereby carried out a virtual screening campaign in order to identify and test novel HuR-mRNA disruptors. Best-scored compounds were tested in an in-vitro model of diabetic retinopathy, namely human retinal endothelial cells (HRECs) challenged with high-glucose levels (25 mM). HuR, VEGF and TNFα protein contents were evaluated by western-blot analysis in total cell lysates. VEGF and TNFα released from HRECs were measured in cell medium by ELISA. We found that two derivatives bearing indole moiety, VP12/14 and VP12/110, modulated HuR expression and decreased VEGF and TNF-α release by HREC exposed to high glucose (HG) levels. VP12/14 and VP12/110 inhibited VEGF and TNF-α release in HRECs challenged with high glucose levels, similarly to dihydrotanshinone (DHTS), a small molecule known to interfere with HuR- TNFα mRNA binding. The present findings demonstrated that VP12/14 and VP12/110 are innovative molecules with anti-inflammatory and anti-angiogenic properties, suggesting their potential use as novel candidates for treatment of diabetic retinopathy. find more Insulin, produced by pancreatic β-cells, is responsible for the control of whole-body glucose metabolism. Insulin is secreted by pancreatic β-cells in a tightly regulated process that is controlled by the serum level of glucose, glucose sensing and glucose oxidative metabolism. The regulation of intermediary metabolism in β-cells is unique as these cells oxidize glucose to CO2 on substrate supply while mitochondrial oxidative metabolism occurs on demand, for the production of intermediates or energy production, in most cell types. This review discusses recent findings that the regulation of intermediary metabolism by nitric oxide attenuates the DNA damage response (DDR) and DNA damage-dependent apoptosis in a β-cell selective manner. Specific focus is placed on the mechanisms by which iNOS derived nitric oxide (low micromolar levels) regulates DDR activation via the inhibition of intermediary metabolism. The physiological significance of the association of metabolism, nitric oxide and DDR signaling for cancer biology and diabetes is discussed. Acetaminophen (APAP) is one of the most frequently used drugs; however, its overdose leads to acute liver injury. Recently, studies have reported that the adduction of peroxiredoxin 6 (PRDX6), a member of the PRDX family of antioxidant enzymes, is associated with liver diseases. However, the role of PRDX6 in APAP-induced liver injury remains unclear. Here, we assessed both age-matched (about 12 weeks) PRDX6-overexpressing transgenic mice (PRDX6 mice) and wild type (WT) mice presenting acute liver injury induced by the intraperitoneal injection of APAP (500 mg/kg). Although PRDX6 is known as an antioxidant enzyme, PRDX6 mice unexpectedly demonstrated severe liver injury following APAP injection compared with WT mice. We observed that PRDX6 was hyperoxidized after APAP administration. Additionally, calcium-independent phospholipase A2 (iPLA2) activity and lysophosphatidylcholine (LPC) levels were markedly elevated in PRDX6 mice following APAP administration. Moreover, APAP-induced JNK phosphorylation was considerably increased in the l
