Description
The objectives of this study were to understand the effect of phenolic compounds from fermented berry beverages on hyperglycemia and obesity in vivo using mice fed a high fat diet. Our hypothesis was that consumption of a fermented blueberry-blackberry beverage and its phenolic compounds would reduce the development of obesity and hyperglycemia in diet-induced obese mice. Body composition, histomorphological analysis of pancreatic islets and liver, and expression of genes involved in obesity and hyperglycemia were evaluated in order to explain the modulation of diet-induced obesity and hyperglycemia due to treatments.

Description
Background: circular RNAs are a class of endogenous RNAs with various functions in eukaryotic cells. Worthy of note, circular RNAs play a critical role in cancer. Currently, nothing is known about the role of circular RNAs in head and neck squamous cell carcinoma (HNSCC). The identification of circular RNAs in HNSCC might become useful for diagnostic and therapeutic strategies in HNSCC.
Publication Title
The oncogenic role of circPVT1 in head and neck squamous cell carcinoma is mediated through the mutant p53/YAP/TEAD transcription-competent complex.

Description
Rationale: The Id1 and Id3 genes play major roles during cardiac development, despite their expression being confined to non-myocardial layers (endocardium endothelium - epicardium). We previously described that Id1/Id3/ double knockout (dKO) mouse embryos die at mid-gestation from multiple cardiac defects, but early demise precluded the studies of the roles of Id in the adult mice.
Publication Title
Developmental ablation of Id1 and Id3 genes in the vasculature leads to postnatal cardiac phenotypes.

Description
Hypoxia, which characterizes most tumor tissues, can alter the function of different immune cell types, favoring tumor escape mechanisms. In this study, we show that hypoxia profoundly acts on NK cells by influencing their transcriptome, affecting their immunoregulatory functions, and changing the chemiotactic responses of different NK cell subsets.
Publication Title
Hypoxia Modifies the Transcriptome of Human NK Cells, Modulates Their Immunoregulatory Profile, and Influences NK Cell Subset Migration.

Description
Duchenne muscular dystrophy (DMD) is an incurable neuromuscular degenerative disease, caused by a mutation in the dystrophin gene. Mdx mice recapitulate DMD features. Here we show that injection of wild-type (WT) embryonic stem cells (ESCs) into mdx blastocysts produces mice with improved pathology. A small fraction of WT ESCs incorporates into the mdx mouse nonuniformly to upregulate protein levels of dystrophin in the skeletal muscle. The chimeric muscle shows reduced regeneration and restores dystrobrevin, a dystrophin-related protein, in areas with high and with low dystrophin content. WT ESC injection also normalizes the amount of fat, a tissue that does not express dystrophin. ESC injection without dystrophin does not prevent the appearance of phenotypes in the skeletal muscle or in the fat. Thus, dystrophin supplied by the ESCs reverses disease in mdx mice globally.
Publication Title
Blastocyst injection of wild type embryonic stem cells induces global corrections in mdx mice.

Description
CONTEXT Slowly progressive chronic tubulo-interstitial damage jeopardizes long-term renal allograft survival. Both immune and non-immune mechanisms are thought to contribute, but the most promising targets for timely intervention have not been identified. OBJECTIVE In the current study we seek to determine the driving force behind progressive histological damage of renal allografts, without the interference of donor pathology, delayed graft function and acute graft rejection. DESIGN We used microarrays to examine whole genome expression profiles in renal allograft protocol biopsies, and analyzed the correlation between gene expression and the histological appearance over time. The gene expression profiles in these protocol biopsies were then compared with gene expression of biopsies with acute T-cell mediated rejection. PATIENTS Human renal allograft biopsies (N=120) were included: 96 rejection-free protocol biopsies and 24 biopsies with T-cell mediated acute rejection. RESULTS In this highly cross-validated study, we demonstrate the significant association of established, ongoing and future chronic histological damage with regulation of adaptive immune gene expression (T-cell and B-cell transcript sets) and innate immune response gene expression (dendritic cell, NK-cell, mast cell and granulocyte transcripts). We demonstrate the ability of gene expression analysis to perform as a quantitative marker for ongoing inflammation with a wide dynamic range: from subtle subhistological inflammation prior to development of chronic damage, over moderate subclinical inflammation associated with chronic histological damage, to marked inflammation of Banff-grade acute T-cell mediated rejection. CONCLUSION Progressive chronic histological damage after kidney transplantation is associated with significant regulation of both innate and adaptive immune responses, months before the histological lesions appear. This study therefore corroborates the hypothesis that quantitative inflammation below the diagnostic threshold of classic T-cell or antibody-mediated rejection is associated with early subclinical stages of progressive renal allograft damage.

Description
The ecto-enzyme CD38 is a marker of unfavorable prognosis for chronic lymphocytic leukemia (CLL) patients and an indicator of activation and proliferation of leukemic cells. Here we show that CD38 is enzymatically active in primary CLL cells and that its forced expression increases disease aggressiveness in a xenograft model. The effect is completely lost when using an enzyme deficient version of CD38 with a single amino-acid mutation. Through the enzymatic conversion of NAD, CD38 increases cytoplasmic Ca2+ concentrations, positively influencing proliferation, chemotaxis, adhesion and matrix digestion. Inhibition of the enzymatic activities of CD38 using the flavonoid kuromanin blocks CLL homing. In a short-term xenograft model using primary cells, kuromanin treatment traps CLL cells in the blood, increasing responses to chemotherapy.

The enzymatic activities of CD38 enhance CLL growth and trafficking: implications for therapeutic targeting.
