Abstract
BACKGROUND Anorexia nervosa (AN) is a serious psychiatric illness associated with significant morbidity and mortality. There is little empirical support for specific treatments and new approaches are sorely needed. This two-site study aimed to determine whether olanzapine is superior to placebo in increasing body mass index (BMI) and improving psychological symptoms in out-patients with AN. METHOD A total of 23 individuals with AN were randomly assigned in double-blind fashion to receive olanzapine or placebo for 8 weeks together with medication management sessions that emphasized compliance. Weight, other physical assessments and measures of psychopathology were collected. RESULTS End-of-treatment BMI, with initial BMI as a covariate, was significantly greater in the group receiving olanzapine [F(1, 20)=6.64, p=0.018]. Psychological symptoms improved in both groups, but there were no statistically significant group differences. Of the 23 participants, 17 (74%) completed the 8-week trial. Participants tolerated the medication well with sedation being the only frequent side effect and no adverse metabolic effects were noted. CONCLUSIONS This small study suggests that olanzapine is generally well tolerated by, and may provide more benefit than placebo for out-patients with AN. Further study is indicated to determine whether olanzapine may affect psychological symptoms in addition to BMI.

Abstract
Ovarian cancer, the most deadly gynecologic malignancy, is often diagnosed late and at the advanced stage when the cancer cells have already migrated and invaded into other tissues and organs. Better understanding of the mechanism of metastasis in ovarian cancer cells is essential to the design of effective therapy. In this study, we investigated the function of scaffolding adaptor protein Gab2 in ovarian cancer cells. Gab2 is found to be overexpressed in a subset of ovarian tumors and cancer cell lines. Gab2 expression mainly regulates the migratory behaviors of ovarian cancer cells. Overexpression of Gab2 promotes the migration and invasion, and down-regulates E-cadherin expression in ovarian cancer cells with low-Gab2 expression. Conversely, knockdown of Gab2 expression inhibits the migration and invasion, and promotes E-cadherin expression in ovarian cancer cells with high-Gab2 expression. By expressing Gab2 wild type and Gab2 mutants that are defective in activation the PI3K and Shp2-Erk pathways, we find that Gab2 inhibits E-cadherin expression and enhances the expression of Zeb1, a transcription factor involved in epithelial-to-mesenchymal transition (EMT), and cell migration and invasion through the activation of the PI3K pathway. Knockdown of Zeb1 expression blocks Gab2-induced suppression of E-cadherin expression and increase in cell invasion. LY294002 and GDC-0941, inhibitors of PI3K, or Rapamycin, an inhibitor of PI3K downstream target mTOR, can reverse the effects of Gab2 on migration and invasion. Overall, our studies reveal that Gab2 overexpression, via activation of the PI3K-Zeb1 pathway, promotes characteristics of EMT in ovarian cancer cells.

Abstract
AIM Arterial extracellular matrix (ECM) remodeling by matrix metalloproteinases (MMPs) is one of the major hallmarks of atherosclerosis. Mimecan, also known as osteoglycin has been implicated in the integrity of the ECM. This study assessed the validity of an enzyme-linked immunosorbent assay (ELISA) developed to measure a specific MMP12-derived fragment of mimecan, MMCN-151, in apolipoprotein-E knockout (ApoE-KO) mice. METHODS AND RESULTS A mouse monoclonal antibody raised against MMCN-151 was used to develop a competitive ELISA. The assay was validated using samples from 20 ApoE-KO and 20 wild type [C57 BL/6] male mice fed a normal or high-fat diet (HFD) for up to 20 weeks. The technical reliability of the assay was established with intra-assay variability <2% and inter-assay variability <10%. The lowest limit of quantification of MMCN-151 was 0.5 ng/ml. ApoE-KO mice fed a HFD for 20 weeks had four-fold increased circulating levels of MMCN-151 compared to baseline, whereas MMCN-151 levels in control mice on HFD increased two-fold compared with baseline. After 10 weeks of a HFD, a significant difference in MMCN-151 levels was observed between ApoE-KO and control mice (P = 0.005) and became more significant at 20 weeks (P = 0.002). CONCLUSIONS The newly developed assay is a reliable detector of MMCN-151 levels which ultimately may be useful indicators of arterial remodeling in patients affected by atherosclerotic disease.

Abstract
228 Background: Gene expression patterns are increasingly capable of stratifying patients based on prognosis and response to therapy. Given the limited availability of sample tissue, however, it is not feasible to utilize every test for every patient, suggesting the need for a universal companion diagnostic assay that is informative with respect to multiple clinical and therapeutic endpoints. Key challenges are identification of appropriate gene expression biomarkers, translation of biomarkers to clinical assays, and development of reliable gene expression profiling of formalin-fixed clinical specimens. Here we describe a novel RT-PCR biomarker assay optimized for FFPE clinical samples that has broad prognostic and predictive potential. Methods: A co-expression meta-analysis of 5,339 breast tumors from 56 microarray datasets identified highly co-expressed sets of genes (modules) across multiple datasets. Module biomarkers were tested for their ability to associate with prognostic and predictive targets in published datasets. In addition, each module was reduced from 10–1000 genes to 2-3 genes for use in companion diagnostic assays based on degree of co-expression across the meta-analysis, and validated against an independent panel of tumor samples. Results: This study demonstrates that a single test utilizing multiple module biomarkers is informative with respect to standard parameters such as ER, PR and Her2, and in addition reproduces existing prognostic and predictive genomic signatures. Furthermore, we show that modules of 10-1000 genes can be represented by 2-3 genes for direct use in companion diagnostics development. Conclusions: The molecular heterogeneity of breast cancer can be summarized by discrete gene expression modules that individually represent distinct biological programs, and that collectively can be represented by as few as 96 genes. Modules, together with outlier genes, allow for summation of the entire transcriptional program and provide a universal assay with broad application to companion diagnostics development.

Abstract
BACKGROUND Treatment of allergic airways disease including asthma remains primarily local immunosuppression with topical corticosteroid and symptomatic management with antihistamines and anti-leucotrienes. We have developed a novel topical therapy designed to specifically inhibit the events associated with Th2 cell activation. OBJECTIVE We assessed the efficacy of our cell-penetrating STAT-6 inhibitory peptide (STAT-6-IP), a novel treatment for allergic airways disease, in a model of chronic ragweed-induced asthma. METHODS Six- to eight-week-old mice were sensitized over 5 weeks with intranasal (IN) exposures to whole ragweed allergen without adjuvant. Mice were then IN challenged with Amba 1 with and without treatment IN with STAT-6-IP and allergic responses assessed. Two weeks later, some animals were rechallenged with Amba 1 with or without STAT-6-IP. RESULTS Animals exposed to IN ragweed developed significant airway hyperresponsiveness and airways inflammation upon challenge. Cell cultures showed increases in Th2 cytokines IL-4 and IL-13. Topical STAT-6-IP treatment reduced production of Th2 cytokines, demonstrated increased expression of IL-10 and reduced frequency of cultured IL-4 positive CD4+ T cells derived from treated mice, suggesting that STAT-6-IP treatment may be immunomodulatory. Airway responsiveness to methacholine challenge in the treatment group was similarly reduced to that of the non-allergic PBS-exposed animals. Importantly, STAT-6-IP-treated mice remained hyporesponsive following second ragweed challenge 2 weeks after treatment. CONCLUSIONS AND CLINICAL RELEVANCE These data suggest that topical application of the STAT-6-IP is sufficient to inhibit allergic airways responses in animals chronically sensitized and challenged with ragweed. Data show that a single topical treatment course is sufficient to block signs of allergic responses to ragweed in the airways for at least 2 weeks. STAT-6-IP is a novel potential treatment for chronic allergic asthma.

Abstract
The relative importance of various human leukocyte antigen (HLA) loci has not been established for unmanipulated HLA-mismatched/haploidentical transplantation. To address this question, we analyzed the impact of HLA-A, HLA-B, HLA-DRB1, HLA-DRB3, HLA-DRB4, and HLA-DRB5 on the outcome of HLA-haploidentical transplantation. Four hundred and eighty-one donor-recipient pairs were fully typed before transplantation. In univariate analysis, HLA-B mismatch not only demonstrated significant adverse effects on acute graft-versus-host disease (GVHD) and transplant-related mortality but also was associated with reduced overall survival and leukemia-free survival (LFS). In multivariate analysis, HLA-B mismatch remained the independent risk factor for acute GVHD and transplant-related mortality. The high risk of disease and the female donor were found to be significant factors for reduced overall survival and LFS. Furthermore, multiple mismatch of the HLA locus was found to have no synergistic adverse effect on outcomes. Our results suggest that prospective matching of patients and donors for HLA-B antigen in the unshared HLA haplotype is warranted for HLA-mismatched/haploidentical transplantation.
