Description
Pomegranate skin extract could prevent fatty liver due to high fat diet in adult male Sprague Dawley rat. There are 3 groups of rats, feeding chow diet, high fat diet and high fat diet combined with pomegrante skin extract. After 8 weeks feeding, high fat diet group developped fatty liver but the other two groups still have healthy liver.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Background and aims: Dysregulation of intestinal epithelial cells performance associates with an array of pathologies whose onset mechanisms are incompletely understood. The aim of the present study was to provide a map of gene expresssion patterns along the human healthy adult gastro-intestinal tract and to implement a new procedure for microarray data noise filtering that would allow their use as a reference when screening for pathological deviations, such as inflammatory bowel disease (IBD). Methods: Gene expression profiles in antrum, duodenum, jejunum, ileum and transverse colon biopsies were measured with the Affymetrix U133A array and principal component analysis was used to identify region-selective biomarkers. These data were intersected with highly variable genes from a public dataset of gene expression in the ileal and colonic healthy regions of UC and Crohns disease patients. Moreover, gene sets covering gut functions not entirely accounted for by the available public tools were constructed to monitor their expression along the GI tract. Results: 166 genes were found to be responsible for distinguishing the five regions considered. Fourteen had never been described in the GI tract, including a semaphorin probably implicated in pathogen invasion, and six other novel genes. Similar analysis of the IBD datasets revealed that samples stratify based on disease rather than on the intestinal region. This withstanding, eleven genes were identified as possible early predictors of Crohns and/or UC in ileum and/or colon. These include CLCA4 and SLC26A2, both implicated in ion transport. Conclusions: This novel approach, validated by retrieving known gene profiles, allowed the identification of promising new leads both in health and IBD state.

Description
Toxoplasma gondii is an obligate intracellular parasite which can cause toxoplasmosis. Surface and secreted proteins of T. gondii play important roles in infection and immunity, and also are antigen targets in immunological diagnosis and vaccine development. However, it is difficult to investigate identities and antigenicities of surface and secreted proteins due to limitation of surface protein extraction methods. In this study, a total of 785 potential surface and secreted proteins of T. gondii RH tachyzoites were identified using a method combination of biotin labeling, avidin chromatography isolation, and high flux proteomics (LC-MS/MS). Among the highly-expressed 65 proteins, 43 proteins (66%) were originally annotated as surface or secreted proteins in the released T. gondii genomes, which proved the method combination to be a credible strategy. Furthermore, the transcriptomic responses and cytokine secretions induced by the isolated proteins, the live T. gondii RH tachyzoites infection, and the live pathogenic E. coli infection, in the human peripheral blood monocyte THP-1 cell lines, were comparatively analyzed to reveal antigenicities and immunobiological properties of T. gondii surface and secreted proteins. The transciptomic profiles induced by the isolated proteins were similar to those induced by the live bacterium infection, but were different from those induced by the live parasite infection. Contrary to the low cytokine secretion induced by the live parasite infection, the isolated proteins induced significant cytokine and chemokines secretion. Especially, the secretions of several chemokines induced by the isolated proteins were even higher than those induced by the live bacterium infection. These data suggested that T. gondii surface and secreted proteins were effective antigens, while the live parasite could evade the host innate immunity. This study comprehensively revealed the identities and antigenicities of T. gondii surface and secreted proteins, which laid foundation for further screening new T. gondii antigens, developing immunological diagnosis methods, and studying host immune response to T. gondii infection.

Description
Neurofibromatosis type II (NF2) is a disease that needs new solutions. Vestibular schwannoma (VS) growth cause progressive hearing loss, and the standard treatment including surgery and radiotherapy, can further damage the nerve. There is an urgent need to identify an adjunct therapy that, by enhancing the efficacy of radiation, can help lower the radiation dose and preserve hearing. The mechanisms underlying deafness in NF2 are still unclear. One of the major limitations in studying tumor-induced hearing loss is the lack of mouse models that allows hearing test. Here we developed a cerebellopontine angle (CPA) schwannomas model that faithfully recapitulates the tumor-induced hearing loss. Using this model we discovered that cMET blockade by crizotinib (CRZ) enhanced schwannoma radiosensitivity by enhancing DNA damage, and CRZ treatment combined with low-dose radiation was as effective as high-dose radiation. CRZ treatment had no adverse effect on hearing; however, it did not affect tumor-induced hearing loss, presumably because cMET blockade did not change tumor HGF levels. cMET gene knockdown study independently confirmed the role of cMET pathway in mediating the effect of CRZ. Furthermore, we evaluated the translational potential of cMET blockade in human schwannomas. We found that human NF2-associated and sporadic VSs showed significantly elevated HGF expression and cMET activation compared to normal nerves, which correlated with tumor growth and cyst formation. Using organoid brain slice culture, cMET blockade inhibited the growth of patient-derived schwannomas. Our findings provide the rationale and necessary data for the clinical translation of combined cMET blockade with radiation therapy in NF2 patients.
