In order to establish a list of candidate direct COUP-TFI gene targets in the inner ear, we analyzed the differential gene expression profiles of the wild-type and the COUP-TFI/ P0 inner ears.

View SamplesMaintenance and propagation of breast cancer stem cells (BCSCs) is mediated via cytokine and growth factor networks. Direct in vivo linkage between dietary regulation of mammary stem (MaSC)/progenitor cell numbers and protection from breast cancer has not been reported. Here, we investigated the effect of post-weaning intake of soy protein isolate (SPI) relative to the control casein (CAS) diet on the stem/progenitor population and tumor formation in MMTV-Wnt1-Transgenic (Wnt1-Tg) female mice. Gene expression profile of the basal (MaSC-enriched) sub-population in preneoplastic Wnt1-Tg mice demonstrated a stem cell-like expression pattern and markedly suppressed expression of inflammatory cytokines, C-X-C family chemokines, and metastasis-associated genes with dietary SPI exposure.

View SamplesWe aimed to identify specific biomarkers of IFN-beta bioactivity in order to compare their gene expression induction by type I IFNs with the MxA, and to investigate their potential role in MS pathogenesis. Gene expression microarrays were performed in PBMC from MS patients who developed neutralizing antibodies (NAB) to IFN-beta. Nine genes followed patterns in gene expression over time similar to the MX1 and were selected for further experiments: IFI6, IFI27, IFI44L, IFIT1, HERC5, LY6E, RSAD2, SIGLEC1, and USP18. In vitro experiments revealed specific induction of selected biomarkers by IFN-beta but not IFN-gamma, and several markers, in particular USP18 and HERC5, were significantly induced at lower IFN-beta concentrations and more selective than the MX1 as biomarkers of IFN-beta bioactivity. In addition, USP18 expression was deficient in MS patients compared with healthy controls (p=0.0004). We propose specific biomarkers that may be considered in addition to the MxA to evaluate IFN-beta bioactivity, and to further explore their implication in MS pathogenesis.

View SamplesAffymetrix gene expression analysis was carried out to investigate the differences in gene profile of MBP89-101-reactive encephalitogenic T cells before and after co-culture with cerebellar granular neurons (CGNs). Co-culture of MBP89-101-reactive encephalitogenic T cells with CGNs leads to generation of T cells with regulatory T cells phenotype (CD4+CD25+membrane bound TGF-b+ T cells) or a new regulatory phenotype (CD4highPD-L1high T cells). CGN-induced CD4+CD25+membrane bound TGF-b+ T regulatory cells, CD4highPD-L1high T cells were purified by FACSAria. IFN-beta induced T lymphocytes (CD4highPD-L1high T cells) were also FACSAria purified. All these populations were compared to MBP89-101-reactive encephalitogenic T cells. Samples were prepared from biological triplicates for each FACSAria sorted population.

View SamplesA genetic study of the PRF1 gene has shown association of several polymorphisms with multiple sclerosis (MS). Haplotype analysis identified risk haplotypes strongly associated with male patients having the primary-progressive form of MS (PPMS). Gene expression microarrays were performed in 10 male PPMS patients carrying the risk (n=6) and protective haplotypes (n=4) in order to identify pathways associated with the risk haplotypes. Pathway analysis revealed overrepresentation of the cell killing gene ontology category among down-regulated genes in patients carrying risk haplotypes compared with patients carrying protective haplotypes.
