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 SamplesPurpose: Here we demonstrate ALK3Bright/PDX1+ cells residing within the human pancreatic ducts have progenitor like characteristics. Using flow cytometery, live-cell sorting of ALK3bright/PDX1+ cells is possible using a surrogate surface marker for PDX1 (P2RY1). Treating ALK3bright/P2RY1+ cells with BMP7 results in their expansion. Later removal of BMP7 results in the differentiation of these cells to ß-like cells. Here we compare the mRNA expression profiles of these three different cell types (in triplicate). Methods: mRNA profiles of ALK3Bright/P2RY1+ cells isolated from human non-endocrine pancreatic tissue, ALK3Bright/P2RY1+ cells treated with BMP7 and ALK3Bright/P2RY1+ cells differentiated to ß-like cells after BMP7 removal were generated by deep sequencing, in triplicate, using Illumina HiSeq PE Cluster Kit v4 and Illumina HiSeq Flow Cell v4 with 50 nt paired end reads plus dual index reads using the Illumina HiSeq SBS kit v4. Sequence reads that passed quality filters were analyzed at the transcript isoform level following alignment using TopHat v2.1.0 followed by exon and gene level counting using Bioconductor easyRNASeq v 2.4.7. Conclusions: Our study represents the first detailed analysis of ALK3Bright/P2RY1+ sorted cells with biological replicates. We demonstrate ALK3Bright/P2RY1+ cells were shown to form progenitor-like epithelial colonies characterized by NKX6.1 and PDX1 expression. Unlike the negative fraction controls, these colonies responded to BMP-7 by generating new ß-like cells as well as cells from other pancreatic lineages. The transcriptional profile of these cells and their BMP7 treated counterparts suggest a mitotic and progenitor like state. Our studies confirm the progenitor-like nature of ALK3Bright/PDX1+ cells within the human pancreas and suggest a specific anatomical location within the ductal network. Overall design: Comparison of transcriptional expression in Alk3Bright/P2RY1+ cells, Alk3Bright/P2RY1+ cells treated with BMP7 and Alk3Bright/P2RY1+ cells allowed to differentiate after BMP7 removal. Human islets, isolated from the same donors were included as a control.

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.
