Background Previous studies have demonstrated that regulatory T cells (Tregs) play a protective role in the pathogenesis of chronic graft-versus-host disease (cGVHD). Tregs constitutively express the gene of the transcription factor Foxp3 whose CNS2 region is heavily methylated in conventional CD4+ T cells (CD4+Tconvs) but demethylated in Tregs. Methods Here, we assessed the impact of azacytidine (AZA) on cGVHD in a well-established murine model of sclerodermic cGVHD (B10.D2 (H-2d) → BALB/cJ (H-2d)). Results The administration of AZA every 48 h from day +10 to day +30 at the dose of 0.5 mg/kg or 2 mg/kg mitigated chronic GVHD. Further, AZA-treated mice exhibited higher blood and thymic Treg frequencies on day +35, as well as higher demethylation levels of the Foxp3 enhancer and the IL-2 promoter in splenocytes at day +52. Interestingly, Tregs from AZA-treated mice expressed more frequently the activation marker CD103 on day +52. AZA-treated mice had also lower counts of CD4+Tconvs and CD8+ T cells from day +21 to day +35 after transplantation, as well as a lower proportion of CD4+Tconvs expressing the Ki67 antigen on day +21 demonstrating an anti-proliferating effect of the drug on T cells. Conclusions Our results indicate that AZA prevented sclerodermic cGVHD in a well-established murine model of cGVHD. These data might serve as the basis for a pilot study of AZA administration for cGVHD prevention in patients at high risk for cGVHD. [less ▲]

Introduction A single tumoral tissue can bear phenotypically different cell populations. This phenomenon called intra-tumor heterogeneity can lead to differential behaviors regarding metastasis seeding and therapy resistance [Zardavas et al., Nature Rev. Clin. Onc. 2015]. MALDI imaging has proven its efficiency for revealing hidden molecular features offering an insight into distinct cellular regions based on their molecular content. Further, proteomics applied to these regions could allow depicting the molecular context associated to particular cells groups and enable the collection of qualitative, quantitative and spatial information for each protein. Methods Breast cancer Formalin Fixed and Paraffin Embedded tissues, from patients whose outcome had been recorded over a period of 10 years, were provided by the department of Pathology of University of Liège. After Citric Acid Antigen Retrieval and trypsin digestion, images were obtained by MALDI-TOF/TOF-MS (Bruker, Germany). From the obtained datasets, segmentation and analytical data analysis were applied using SCiLS (Bruker, Germany) and the cloud software Multimaging (ImaBiotech, France). Small tissue areas were obtained by laser microdissection (LEICA LMD 700, Germany), upon which a combination of chemical processes was applied to ensure optimal protein antigen retrieval, extraction and digestion. Finally, the tissue pieces obtained were analyzed by LC-MS/MS using UPLC Waters Nanoacquity and Thermo Q-Exactive instruments. Preliminary data Based on mathematical calculations for the MALDI imaging datasets of the breast cancer FFPE tissues, Regions Of Interest (ROIs) were detected in a single tumor, revealing intra-tumoral heterogeneity, which can be correlated to the level of aggressiveness of the affliction and to the final prognosis of the patient. We aimed to compare the proteomic profiles of each of the small ROIs. Until today, proteomics applied to tissues composed by a restricted number of cells is quite tedious due to possible tissue losses during their handling. Recently, Longuespée [Longuespée et al., Methods 2015] published a method in order to retrieve the identification of 1400 proteins from microdissected tissue pieces containing only 2700 cells. This whole procedure allowed us to identify a panel of protein that characterizes tissue heterogeneity within a single tumor. This proves the applicability of the combination of MALDI imaging for the discovery of intra-tumoral heterogeneity without a priori, on a mathematical basis, and classical proteomics applied on laser-microdissected tissue samples of very restricted areas. This method will now be applied to several MALDI datasets in order to retrieve commune ROIs and to associate their presence with the information of each patient, such as their prognosis. Those ROIs will then be microdissected and subjected to microproteomic methods that will allow us to retrieve the extensive molecular context associated to bad patient prognosis and/or therapy resistance. The possibility to identify protein/peptide markers will have the power to predict the outcome of the breast cancer patient at the beginning of their treatment, and thus, improve the clinical care for the benefit of the patients. Novel aspect The workflow combines the unique advantages of MALDI imaging for de novo molecular features characterization and LMD-based microproteomics. [less ▲]

- Introduction: Glioblastoma (GBM) is the most aggressive and common solid human brain tumor. Because of GBM heterogeneity, location and aggressiveness, none of the available treatment is curative. These treatments include maximal surgical resection, radiotherapy and concomitant or adjuvant chemotherapy with Temozolomide. However, the prognosis of adult patients with GBM remains poor and the survival outcome after treatment does not exceed 15 months. GBM-composing cells have developed many strategies to counteract these current therapies. Among the wide hallmarks acquired to survive, high osteopontin (OPN) expression correlates with lower overall and disease-free/relapse-free survival in all tumors combined, as well in brain cancer. Our recent study (Lamour V and Henry A, IJC 2015) has demonstrated the role of OPN in the tumorigenicity of glioblastoma cells and its importance in the maintenance of the stem characters. In the continuation of this work, our recent studies focused on the potential role of OPN in the resistance of GBM cells to radiotherapy and its potential implication in the initiation of Double Strand Breaks (DSBs) repair mechanisms. - Aims: In the context of this study, different GBM cell lines (U251-MG, U87-MG and U87 Viii) were used to assess the role of OPN in the initiation of the DSBs repair mechanism after an exposure to gamma-irradiation. - Methods and results: We performed the transient transfection of different GBM cell lines (U251-MG, U87-MG and U87-MG overexpressing EGFR VIII) with siRNAs specifically directed against OPN. After irradiation, all these OPN-depleted cells consistently showed a lower induction of γ–H2AX compared to control (irrelevant siRNA) as evidenced by western blot and immunofluorescence techniques. Thereafter, clonogenic assays allowed to prove that the survival of OPN-depleted cells was affected after an exposure to irradiation. To assess the importance of OPN expression in the response to radiotherapy, an heterotopic xenograft model was used. In brief, IPTG-inducible U87 shOPN clones were injected subcutaneously in NOD-SCID mice and were allowed to form a tumor. When average tumor volume reached a predetermined size range, mice were treated (or not) with IPTG by intraperitoneal injection during five days. At the end of the treatment, tumors were selectively exposed to gamma-irradiation by using a small animal irradiator X-RAD 225Cx (Precision X-Ray Inc., North Branford, CT). One week later, mice were sacrificed and tumors were measured. In this pilot study, we observed that mice in which the tumor was depleted in OPN displayed a slight regression in the tumor growth compared to mice that received radiotherapy alone (no IPTG), where the tumor volume remained constant. - Conclusions: Taken together, these preliminary data meet the fact that OPN is important in the response of GBM to radiotherapy. The in vitro results converge to the fact that OPN might be implicated in the initiation of the DSBs repair following irradiation. Currently, we would like to investigate this hypothesis in vivo but also to check the effect of OPN depletion combined to radiotherapy on the survival of mice in an orthotopic xenograft model.

Human rescue dog unit are amongst the most efficient tools to locate cadaver or individuals trapped after a natural disaster. However, the dog training process is long and expensive. Dog trainers are still looking for a better understanding of the dog olfaction matching mechanism to improve their training methods (1). How does the decomposition process differ between organs? Are there specific body parts better suited for dog training? What are the major volatile compounds responsible of the dogs’ match response? In the line of these questions, this project was monitoring the headspace of various human organs during the decomposition process. Five different organs, from five different bodies, were used: heart, lung, liver, kidney, and blood. Each organs were sampled in triplicates and let to decompose in glass jar. Regularly, the headspace of the jar was sampled by dynamic pumping to sorbent tubes that were further be desorbed on a comprehensive two-dimensional gas chromatography system (GC×GC). GC×GC is a powerful analytical tool that allows the resolution of “the smell of death”, i.e. the decomposition odor (2-3). The development of an in vitro approach for decomposition monitoring provided several analytical improvements in the decomposition field. Indeed, the study of dead bodies is always limited in the number of replicates (4). The sampling process developed for this project allows intra and inter corpse comparison with at least triplicates sampling. These comparisons were conducted using advanced chemometric methods (Fisher ratio, PCA, hierarchical analysis…) that will contribute to better understand key parameters of rescue the dog training.

OBJECTIVE: Treating metastatic colorectal cancer with anti-EGFR monoclonal antibodies is recommended only for patients whose tumour does not harbour mutations of KRAS or NRAS. The aim of this study was to investigate the biology of rectal cancers and specifically to evaluate the relationship between fluorine-18 fludeoxyglucose (18F-FDG) positron emission tomography (PET) intensity and heterogeneity parameters and their mutational status. METHODS: 151 patients with newly diagnosed rectal cancer were included in this retrospective study. All patients underwent a baseline 18F-FDG PET/CT within a median time interval of 27 days of tumour tissue sampling, which was performed before any treatment. Standardized uptake values (SUVs), volume-based parameters and texture analysis were studied. We retrospectively performed KRAS genotyping on codons 12, 13, 61, 117 and 146, NRAS genotyping on codons 12, 13 and 61 and BRAF on codon 600. Associations between PET/CT parameters and the mutational status were assessed using univariate and multivariate analysis. RESULTS: 83 (55%) patients had an RAS mutation: 74 KRAS and 9 NRAS, while 68 patients had no mutation (wild-type tumours). No patient had BRAF mutation. First-order features based on intensity histogram analysis were significantly associated with RAS mutations: maximum SUV (SUVmax) (p-value = 0.002), mean SUV (p-value = 0.006), skewness (p-value = 0.049), SUV standard deviation (p-value = 0.001) and SUV coefficient of variation (SUVcov) (p-value = 0.001). Both SUVcov and SUVmax showed an area under the curve of 0.65 with sensitivity of 56% and 69%, respectively, and specificity of 64% and 52%, respectively. None of the volume-based (metabolic tumour volume and total lesion glycolysis), nor local or regional textural features were associated with the presence of RAS mutations. CONCLUSION: Although rectal cancers with KRAS or NRAS mutations display a significantly higher glucose metabolism than wild-type cancers, the accuracy of the currently proposed quantitative metrics extracted from 18F-FDG PET/CT is not sufficiently high for playing a meaningful clinical role. ADVANCES IN KNOWLEDGE: RAS-mutated rectal cancers have a significantly higher glucose metabolism. However, the accuracy of 18F-FDG PET/CT quantitative metrics is not as such as the technique could play a clinical role. [less ▲]

PURPOSE: Our primary objective was to determine if [18F]FPRGD2 PET/CT performed at baseline and/or after chemoradiotherapy (CRT) could predict tumour regression grade (TRG) in locally advanced rectal cancer (LARC). Secondary objectives were to compare baseline [18F]FPRGD2 and [18F]FDG uptake, to evaluate the correlation between posttreatment [18F]FPRGD2 uptake and tumour microvessel density (MVD) and to determine if [18F]FPRGD2 and FDG PET/CT could predict disease-free survival. METHODS: Baseline [18F]FPRGD2 and FDG PET/CT were performed in 32 consecutive patients (23 men, 9 women; mean age 63 +/- 8 years) with LARC before starting any therapy. A posttreatment [18F]FPRGD2 PET/CT scan was performed in 24 patients after the end of CRT (median interval 7 weeks, range 3 - 15 weeks) and before surgery (median interval 4 days, range 1 - 15 days). RESULTS: All LARC showed uptake of both [18F]FPRGD2 (SUVmax 5.4 +/- 1.5, range 2.7 - 9) and FDG (SUVmax 16.5 +/- 8, range 7.1 - 36.5). There was a moderate positive correlation between [18F]FPRGD2 and FDG SUVmax (Pearson's r = 0.49, p = 0.0026). There was a moderate negative correlation between baseline [18F]FPRGD2 SUVmax and the TRG (Spearman's r = -0.37, p = 0.037), and a [18F]FPRGD2 SUVmax of >5.6 identified all patients with a complete response (TRG 0; AUC 0.84, 95 % CI 0.68 - 1, p = 0.029). In the 24 patients who underwent a posttreatment [18F]FPRGD2 PET/CT scan the response index, calculated as [(SUVmax1 - SUVmax2)/SUVmax1] x 100 %, was not associated with TRG. Post-treatment [18F]FPRGD2 uptake was not correlated with tumour MVD. Neither [18F]FPRGD2 nor FDG uptake predicted disease-free survival. CONCLUSION: Baseline [18F]FPRGD2 uptake was correlated with the pathological response in patients with LARC treated with CRT. However, the specificity was too low to consider its clinical routine use. [less ▲]

To date, the mutational status of EGFR and PTEN has been shown as relevant for favoring pro- or anti-tumor functions of STAT3 in human glioblastoma multiforme (GBM). We have screened genomic data from 154 patients and have identified a strong positive correlation between STAT3 and HDAC7 expression. In the current work we show the existence of a subpopulation of patients overexpressing HDAC7 and STAT3 that has particularly poor clinical outcome. Surprisingly, the somatic mutation rate of both STAT3 and HDAC7 was insignificant in GBM comparing with EGFR, PTEN or TP53. Depletion of HDAC7 in a range of GBM cells induced the expression of tyrosine kinase JAK1 and the tumor suppressor AKAP12. Both proteins synergistically sustained the activity of STAT3 by inducing its phosphorylation (JAK1) and protein expression (AKAP12). In absence of HDAC7, activated STAT3 was responsible for significant imbalance of secreted pro-/anti-angiogenic factors. This inhibited the migration and sprouting of endothelial cells in paracrine fashion in vitro as well as angiogenesis in vivo. In a murine model of GBM, induced HDAC7-silencing decreased the tumor burden by threefold. The current data show for the first time that silencing HDAC7 can reset the tumor suppressor activity of STAT3, independently of the EGFR/PTEN/TP53 background of the GBM. This effect could be exploited to overcome tumor heterogeneity and provide a new rationale behind the development of specific HDAC7 inhibitors for clinical use. [less ▲]

Pancreatic ductal adenocarcinoma is one of the most deadly forms of cancers with no satisfactory treatment to date. Recent studies have identified myoferlin, a ferlin family member, in human pancreas adenocarcinoma where its expression was associated to a bad prognosis. However, the function of myoferlin in pancreas adenocarcinoma has not been reported. In other cell types, myoferlin is involved in several key plasma membrane processes such as fusion, repair, endocytosis and tyrosine kinase receptor activity. In this study, we showed that myoferlin silencing in BxPC-3 human pancreatic cancer cells resulted in the inhibition of cell proliferation in vitro and in a significant reduction of the tumor volume in chick chorioallantoic membrane assay. In addition to be smaller, the tumors formed by the myoferlin-silenced cells showed a marked absence of functional blood vessels. We further demonstrated that this effect was due, at least in part, to an inhibition of VEGFA secretion by BxPC-3 myoferlin-silenced cells. Using immunofluorescence and electron microscopy, we linked the decreased VEGFA secretion to an impairment of VEGFA exocytosis. The clinical relevance of our results was further strengthened by a significant correlation between myoferlin expression in a series of human pancreatic malignant lesions and their angiogenic status evaluated by the determination of the blood vessel density.

Introduction: Graft-versus-host disease (GVHD) has remained a major complication of allogeneic hematopoietic stem cell transplantation (HSCT) for the last decades. Following unmanipulated peripheral-blood stem cell transplantation, 60% of the patients experience chronic GVHD while approximately 15% of them develop a sclerodermic form of chronic GVHD characterized by multiple organ fibrosis and loss of skin elasticity. Regulatory T cells (Tregs) play a pivotal protective role in the pathogenesis of chronic GVHD by inhibiting alloreactive conventional T cells (Tconvs). Several studies have shown that hypomethylating agents such as azacytidine (Aza) can demethylate the master transcription factor of Treg (Forkhead box protein 3 factor, FoxP3), thus promoting Treg differentiation from Tconvs. This work investigates the impact of Aza in a classical murine model of sclerodermic chronic GVHD (B10.D2  BALB/cJ). Methods: In vitro analyses have been performed to determine the impact of Aza on collagen production. NIH-3T3 fibroblastic cells were plated and stimulated with 50 ng of PDGF or 10 ng of TGF-beta. Cells were then cultured with various concentrations of Aza for 48 hours. After culture, cells were stained with Sirius Red before quantification of collagen amount by absorbance at 490 nm. For in vivo experiments, lethally irradiated (7 Gy) BALB/cJ recipient mice were injected with 107 bone marrow cells + 7.107splenocytes from B10.D2 donor mice to induce scl-cGVHD. Recipients were injected with either 0,5 or 2 mg/kg of Aza every 48 hours from day 10 to 30 following transplantation. GVHD was scored using a five criteria scale (weight loss, activity, fibrosis, hair loss and mice posture; 0-1-2 points/criteria). Mice were sacrificed at a score of 8/10 (or > 20% weight loss) or at day 52 after transplantation (end of experiment). Results: Concerning in vitro analyses, results suggest a decreased production of collagen at higher concentration of Aza with both stimulations (seen by a gradual diminution of absorbance). For in vivo experiments, mice treated with Aza 0.5 mg/kg (n = 14) or 2 mg/kg (n = 25) had significant lower clinical scores of GVHD compared to control ones (n = 23) after treatment. FACS analysis showed a higher proportion of Treg among CD4+ T cells in the blood of Aza 2 mg/kg mice than in control mice at day 35 following transplantation (P = 0.047), as well as a higher percentage of Tregs expressing the KI67 proliferative marker on the same time point (P = 0.0005). Finally, analyses of the cellular blood components with Cell-dyn demonstrated that Aza 2 mg/kg treated mice were significantly lymphopenic as compared to control mice at day 35 after transplantation (P = 0.05). Conclusion : Aza prevented sclerodermic GVHD in this classical murine model of chronic GVHD. [less ▲]

Gestational trophoblastic diseases include placental pathologies comprising fertilization abnormalities (hydatidiform moles) and malignant lesions (choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor). Due to their low incidence and heterogeneity, their diagnosis, management and treatment are not always optimal. Following the example of other European countries, a national registration system with two reference centers has been set up to guide physicians and patients and to propose individualized management. The centers offer their expertise through a systematic centralised pathology review by a panel of experts. HCG values are plotted in regression curves. In case of gestational trophoblastic neoplasia, an imaging work-up is proposed, from which the FIGO score and stage are derived and will guide the choice of treatment. Belgian centers offer a multidisciplinary approach, in partnership with the referent physician. More information for practitioners and patients is available on a web site: www.mole-chorio-bgog.eu, which also harbours a forum of discussion. [less ▲]
