Abstract
The proinsulin molecule results from the cleavage of pre-pro-insulin, produced in pancreatic beta cells. Its subsequent -cleavage allows the release of insulin, the key hormone of glycemia regulation and C-peptide in equimolar proportions. During fasting trial, insulinoma diagnosis relies on inadequately high insulin and C-peptide serum levels concomitant with an hypoglycemia. In this context, proinsulin assay can be interesting in the cases of discrepancy between the two parameters. In diabetes, endoplasmic reticulum stress and beta cells inflammation, lead to the secretion of misfolded proinsulin molecules. Thus, in type 2 diabetes, proinsulin/insulin ratio increases with the degree of insulin resistance. In type 1 diabetes, proinsulin/C-peptide ratio could predict the onset of diabetes in relatives. In our practice, serum pro-insulin determined using an Elisa immunoassay (Millipore®) during fasting trial can be complementary to C-peptide and insulin assays in relation to glycemia to label an hypoglycemia. In case of glucose intolerance and diabetes, proinsulin could thus be measured.

Abstract
It is now well established that maternal serum markers are often abnormal in fetal trisomy 21. Their determination is recommended for prenatal screening and pregnancy follow-up. However, mechanisms leading to abnormal maternal serum levels of such markers are still debated. Our objective was to help clinicians and scientists unravel the pathophysiology of these markers via a review of the main studies published in this field, both in vivo and in vitro, focusing on the six most widely used markers (hCG, its free subunit hCGβ, PAPP-A, AFP, uE3, and inhibin A) as well as cell-free feto-placental DNA. Analysis of the literature shows that mechanisms underlying each marker's regulation are multiple and not necessarily directly linked with the supernumerary chromosome 21. The crucial involvement of the placenta is also highlighted, which could be defective in one or several of its functions (turnover and apoptosis, endocrine production, and feto-maternal exchanges and transfer). These defects were neither constant nor specific for trisomy 21, and might be more or less pronounced, reflecting a high variability in placental immaturity and alteration. This explains why maternal serum markers can lack both specificity and sensitivity, and are thus restricted to screening.

Abstract
Although its powerful impact on most co-morbidities has been widely demonstrated, the metabolic outcomes of bariatric surgery (BS) show a great heterogeneity among patients. Haplotypes of one of the major antioxidant enzyme, catalase (CAT), are associated with hypertension, dyslipidemia, and diabetes. The haplotype referred to as CAT1 includes homozygous carriers of CATH1 [-844G,-89A,-20T], whereas CAT2 haplotype includes heterozygous carriers (CATH1/CATH2) and CATH2 homozygous [-844A,-89T,-20C]. The aim of our study was to evaluate the impact of CAT1 and CAT2 haplotypes on traditional cardiovascular and metabolic markers one year after BS in a women population. The 294 women with a body mass index (BMI) >35 kg/m2 were followed-up for one year after BS, monitoring their anthropometric, metabolic and inflammatory parameters. CAT1 patients had significantly improved diastolic blood pressure (DBP) and Creactive protein (CRP) levels compared to CAT2 one year after BS. In untreated women at baseline, the change of CRP one year after BS was higher in CAT1 patients. In the population of women receiving at least one anti-lipidic, anti-hypertensive or anti-diabetic treatment at baseline, DBP and fat mass were lower one year after BS in CAT1 patients and the greater change of fat mass was associated with a higher change of adiponectin. The results highlight the beneficial impact of the CAT1 haplotype on traditional cardiovascular and metabolic parameters after BS. Our findings suggest that the CAT1 haplotype could be implicated in the level of metabolic and cardiovascular improvement after BS.

Abstract
The perpetuation of angiogenesis is involved in certain chronic inflammatory diseases. The accelerated neovascularisation may result from an inflammatory status with a response of both endothelial cells and monocytes to inflammatory mediators such as chemokines. We have previously described in vitro and in vivo the pro-angiogenic effects of the chemokine Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES)/CCL5. The effects of RANTES/CCL5 may be related to its binding to G protein-coupled receptors and to proteoglycans such as syndecan-1 and -4. The aim of this study was to evaluate the functionality of syndecan-4 as a co-receptor of RANTES/CCL5 by the use of mutated syndecan-4 constructs. Our data demonstrate that site-directed mutations in syndecan-4 modify RANTES/CCL5 biological activities in endothelial cells. The SDC4S179A mutant, associated with an induced protein kinase C (PKC)α activation, leads to higher RANTES/CCL5 pro-angiogenic effects, whereas the SDC4L188QQ and the SDC4A198del mutants, leading to lower phosphatidylinositol 4,5-bisphosphate (PIP2) binding or to lower PDZ protein binding respectively, are associated with reduced RANTES/CCL5 cellular effects. Moreover, our data highlight that the intracellular domain of SDC-4 is involved in RANTES/CCL5-induced activation of the PKCα signaling pathway and biological effect. As RANTES/CCL5 is involved in various physiopathological processes, the development of a new therapeutic strategy may be reliant on the mechanism by which RANTES/CCL5 exerts its biological activities, for example by targeting the binding of the chemokine to its proteoglycan receptor.

Abstract
BACKGROUND Proteoglycans are involved in neoangiogenesis and transduction of oncogenic signals, two hallmarks of carcinogenesis. METHODS This study sought to assess the prognostic value of serum levels of three proteoglycans (endocan, syndecan-1, and glypican-3) and VEGF in 295 patients with alcoholic cirrhosis: 170 without hepatocellular carcinoma, 58 with early hepatocellular carcinoma, and 67 with advanced hepatocellular carcinoma at inclusion. We analyzed the association between proteoglycan levels and prognosis using Kaplan-Meier and Cox methods. RESULTS Serum levels of the three proteoglycans and VEGF were increased in patients with advanced hepatocellular carcinoma compared with those without hepatocellular carcinoma or with early hepatocellular carcinoma. In multivariate analysis, high levels of serum endocan (>5 ng/mL) were independently associated with death [HR, 2.84; 95% confidence interval (CI,) 1.18-6.84; P = 0.02], but not with hepatocellular carcinoma occurrence, in patients without hepatocellular carcinoma at baseline. High serum endocan (>5 ng/mL) and syndecan-1 (>50 ng/mL) levels were significantly associated with greater risk of tumor recurrence (P = 0.025) in patients with early hepatocellular carcinoma treated by radiofrequency ablation. In patients with advanced hepatocellular carcinoma, high serum levels of endocan (P = 0.004) and syndecan-1 (P = 0.006) were significantly associated with less favorable overall survival. However, only a high level of serum syndecan-1 (>50 ng/mL) was independently associated with greater risk of death (HR, 6.21 95% CI, 1.90-20.30; P = 0.0025). CONCLUSION Serum endocan and syndecan-1 are easily assessable prognostic serum biomarkers of overall survival in alcoholic cirrhosis with and without hepatocellular carcinoma. IMPACT These new biomarkers will be useful to manage patients with hepatocellular carcinoma developed on alcoholic cirrhosis.

Abstract
BACKGROUND The deregulation of several transcription factors contribute to the aggressive course of mantle cell lymphoma. This study focuses on survival signals emanating from the tumor environment and involving the signal transducer and activator of transcription (STAT) 3 through cytokines or antigen recognition. DESIGN AND METHODS Primary mantle cell lymphoma cells were isolated from 20 leukemic patients. The phosphorylation status of STAT3 was evaluated by immunoblottting and immunofluorescence, the levels of cytokine secretion by enzyme-linked immunosorbent assay and the cell survival signals by apoptosis and cell viability assays. RESULTS STAT3 was constitutively phosphorylated in the Jeko-1 mantle cell lymphoma cell line and in 14 out of 20 (70%) cases of leukemic mantle cell lymphoma as the result of an autocrine secretion of interleukin-6 and/or interleukin-10. In addition, B-cell receptor engagement resulted in an increase of both in vitro cell survival and STAT3 phosphorylation in primary mantle cell lymphoma cells. Inhibition of the Janus-activated kinase/STAT3 pathway increased spontaneous apoptosis and suppressed B-cell receptor-induced cell survival in all cases analyzed. The impact of in vitro exposure to the proteasome inhibitor bortezomib was next evaluated in primary mantle cell lymphoma cells. Bortezomib induced apoptosis and a decrease of both interleukin-6/interleukin-10 secretion and STAT3 phosphorylation. In addition, bortezomib inhibited B-cell receptor-triggered STAT3 phosphorylation and cell survival. CONCLUSIONS We demonstrated that STAT3 was activated in primary mantle cell lymphoma cells either constitutively through a cytokine autocrine loop or in response to B-cell receptor engagement, both processes leading to a survival signal inhibited by bortezomib. STAT3 appears, therefore, to play a pivotal role in mantle cell lymphoma and represents a promising therapeutic target.

Abstract
The aim of our study was to investigate whether myofibroblasts and the chemokine monocyte chemoattractant protein-1 (MCP-1)/CCL2 may play a role in hepatocellular carcinoma progression. We observed that hepatic myofibroblast LI90 cells express MCP-1/CCL2 mRNA and secrete this chemokine. Moreover, myofibroblast LI90 cell-conditioned medium (LI90-CM) induces human hepatoma Huh7 cell migration and invasion. These effects are strongly reduced when a MCP-1/CCL2-depleted LI90-CM was used. We showed that MCP-1/CCL2 induces Huh7 cell migration and invasion through its G-protein-coupled receptor CCR2 and, to a lesser extent, through CCR1 only at high MCP-1/CCL2 concentrations. MCP-1/CCL2's chemotactic activities rely on tyrosine phosphorylation of focal adhesion components and depend on matrix metalloproteinase (MMP)-2 and MMP-9. Furthermore, we observed that Huh7 cell migration and invasion induced by the chemokine are strongly inhibited by heparin, by beta-D-xyloside treatment of cells and by anti-syndecan-1 and -4 antibodies. Finally, we developed a 3-dimensional coculture model of myofibroblast LI90 and Huh7 cells and demonstrated that MCP-1/CCL2 and its membrane partners, CCR1 and CCR2, may be involved in the formation of mixed hepatoma-myofibroblast spheroids. In conclusion, our data show that human liver myofibroblasts act on hepatoma cells in a paracrine manner to increase their invasiveness and suggest that myofibroblast-derived MCP-1/CCL2 could be involved in the pathogenesis of hepatocellular carcinoma.

Abstract
UNLABELLED Alcohol increases reactive oxygen species (ROS) formation in hepatocyte mitochondria and by reduced nicotinamide adenine dinucleotide phosphate oxidases and myeloperoxidase (MPO) in Kupffer cells and liver-infiltrating neutrophils. Manganese superoxide dismutase (MnSOD) converts superoxide anion into hydrogen peroxide, which, unless detoxified by glutathione peroxidase or catalase (CAT), can form the hydroxyl radical with iron. Our aim was to determine whether Ala16Val-superoxide dismutase 2 (SOD2), G-463A-MPO, or T-262C-CAT dimorphisms modulate the risks of hepatocellular carcinoma (HCC) and death in alcoholic cirrhosis. Genotypes and the hepatic iron score were assessed in 190 prospectively followed patients with alcoholic cirrhosis. During follow-up (61.1 +/- 2.7 months), 51 patients developed HCC, and 71 died. The T-262C-CAT dimorphism did not modify hepatic iron, HCC, or death. The GG-MPO genotype did not modify iron but increased the risks of HCC and death. The hazard ratio (HR) was 4.7 (2.1-10.1) for HCC and 3.6 (1.9-6.7) for death. Carriage of one or two Ala-SOD2 allele(s) was associated with higher liver iron scores and higher risks of HCC and death. The 5-year incidence of HCC was 34.4% in patients with both the GG-MPO genotype and one or two Ala-SOD2 alleles, 5.1% in patients with only one of these two traits, and 0% in patients with none of these traits. Corresponding 5-year death rates were 37.6%, 11.6%, and 5%. CONCLUSION The combination of the GG-MPO genotype (leading to high MPO expression) and at least one Ala-SOD2 allele (associated with high liver iron score) markedly increased the risks of HCC occurrence and death in patients with alcoholic cirrhosis.

Abstract
Arterial ageing - arteriosclerosis - is characterised by both thickening and stiffening of the walls of large and medium arteries. The molecular and cellular mechanisms (i.e. endothelial dysfunction, matrix remodelling, ...) involved in this process are complex, and at least in part common to atherosclerotic injury. Arterial stiffness is strongly associated with cardiovascular disease and an increased risk of morbidity and mortality. The aim of this review is to provide an update on the pathophysiology and the biological process of arterial ageing and to underline the main difference with atherosclerosis damage process in particularly during the calcification step.

Abstract
The signal transducers and activators of transcription (STATs) convey signals from the membrane to the nucleus in response to cytokines or growth factors. STAT3 is activated in response to cytokines involved mostly in cell proliferation; STAT1 is activated by cytokines, including interferon-gamma, involved in defence against pathogens and the inhibition of cell proliferation. STAT3, which is frequently activated in tumour cells, is a valuable target with respect to achieving inhibition of tumour cell proliferation. Indeed, its inhibition results in cell death. We previously observed that inhibition of the transcription factor nuclear factor-kappaB, a key regulator of cell proliferation, with decoy oligodeoxynucleotides results in cell death. We used a similar approach for STAT3. A hairpin STAT3 oligodeoxynucleotide was added to a colon carcinoma cell line in which it induced cell death as efficiently as the STAT3 inhibitor stattic. The hairpin STAT3 oligodeoxynucleotide co-localized with STAT3 within the cytoplasm, prevented STAT3 localization to the nucleus, blocked a cyclin D1 reporter promoter and associated with STAT3 in pull-down assays. However, the same cells were efficiently killed by interferon-gamma. This effect was counteracted by the STAT3 oligodeoxynucleotide, which was found to efficiently inhibit STAT1. Thus, although it can inhibit STAT3, the hairpin STAT3 oligodeoxynucleotide appears also to inhibit STAT1-mediated interferon-gamma cell killing, highlighting the need to optimize STAT3-targeting oligodeoxynucleotides.

Abstract
The transcription factor NF-kappaB is frequently activated in cancer, and is therefore a valuable target for cancer therapy. Decoy oligodeoxynucleotides (ODNs) inhibit NF-kappaB by preventing its binding to the promoter region of target genes. Few studies have used NF-kappaB-targeting with ODNs in cancer. Using a hairpin NF-kappaB-decoy ODN we found that it induced growth inhibition and cell death in NF-kappaB-dependent tumour cell lines. The ODN colocalized with the p50 subunit of NF-kappaB in cells and directly interacted with it in nuclear extracts. In TNFalpha-treated cells the ODN and the p50 subunit were found in the cytoplasm suggesting that the complex did not translocate to the nucleus. Transcriptional activity of NF-kappaB was efficiently inhibited by the ODN, whereas a scrambled ODN was without effect on transcription. Thus, ODN-mediated inhibition of NF-kappaB can efficiently promote cell death in cancer cells providing a potentially powerful approach to tumour growth inhibition.

Abstract
Chronic inflammation and immunosuppressive therapies increase the risk of non-Hodgkin's lymphoma associated or not with Epstein-Barr virus (EBV) infection. A possible link between infliximab treatment and increased risk of lymphoma has been suggested. Indeed, infliximab induces apoptosis of monocytes and activated T lymphocytes, but its effect on B lymphocytes infected or not with EBV is unknown. Secreted tumor necrosis factor (TNF) alpha and the expression level of TNF receptor 1 (TNFR1) and TNFR2 were compared in EBV-positive and negative B-cell lines. The impact of TNFalpha and infliximab on apoptosis of EBV-positive cells was analyzed regarding the activity of NF-kappaB. Increased expression of TNFalpha in EBV-positive cells suggested that infliximab could affect their survival. However, TNFalpha or infliximab incubation had no effect on apoptosis of EBV-positive cells. Loss of NF-kappaB activity sensitized lymphoblastoid cell lines to TNFalpha-induced apoptosis, but no direct effect of infliximab on apoptosis was detected. On the basis of our in vitro data, neither TNFalpha nor infliximab has a direct effect on apoptosis of B lymphocytes and EBV-positive cell lines. Thus, if an increased incidence of lymphoma were induced by TNFalpha blockers, it would not involve a direct effect on B cells but rather an impaired immune surveillance by T cells.

Abstract
Constitutive activation of signal transducer and activator of transcription 1 (STAT1) is a distinctive feature of Epstein-Barr virus (EBV)-immortalized B cells (lymphoblastoid cell lines [LCLs]). The expression of STAT1 in these cells is modulated by the latent membrane protein 1 (LMP1), but the mechanism of STAT1 activation has remained unclear. We demonstrate that the tyrosine phosphorylation of STAT1 in LCLs results from an indirect pathway encompassing an NF-kappaB-dependent secretion of interferons (IFNs). The cell culture supernatant of LCLs induced tyrosine phosphorylation of STAT1 in cells with no constitutively activated STAT1. Moreover, removal of supernatant from LCLs was sufficient to decrease the phosphorylation of STAT1. Inhibition of NF-kappaB activity by different pharmacological inhibitors (i.e., parthenolide, MG132 and BAY 11-7082) and by overexpressed mutated IkappaBalpha prevented the activation of STAT1. To identify the factors involved, we performed macroarray cDNA profiling with or without inhibition of NF-kappaB. The expression of several cytokines was NF-kappaB dependent among those alpha and gamma IFNs (IFN-alpha and IFN-gamma), known activators of STAT1. By real-time PCR and enzyme-linked immunosorbent assay we show that IFN-alpha and IFN-gamma are expressed and released by LCLs in an NF-kappaB-dependent manner. Finally, the blocking of the IFN-alpha and IFN-gamma by neutralizing antibodies led to the complete inhibition of tyrosine phosphorylation of STAT1. Taken together, our results clearly show that LMP1-induced tyrosine phosphorylation of STAT1 is almost exclusively due to the NF-kappaB-dependent secretion of IFNs. Whether this response, which is usually considered to be antiviral, is in fact required for the persistence of the virus remains to be elucidated.
