Background: Malignant peripheral nerve sheath tumors (MPNST) are soft-tissue sarcomas that can arise either sporadically or in association with neurofibromatosis type 1 (NF1). These aggressive malignancies confer poor survival, with no effective therapy available.

View SamplesGene expression of T47D-MTVL human breast cancer cells expressing Dox-inducible shRNAs against histone H1.4 (120sh) or multiple H1 variants (225sh) Overall design: Stable breast cancer-derived cell lines expressing an shRNA against one of each of the histone H1 isoforms in response to doxycycline (Dox) were grown for six days in the presence or absence of Doxicycline, RNA extracted and high-thorughput sequenced. Cell lines used: inducible shRNA against H1.4 or multiple H1 variants and random shRNA-expression vector.
Histone H1 depletion triggers an interferon response in cancer cells via activation of heterochromatic repeats.

View SamplesMany successful vaccines induce persistent antibody responses that can last a lifetime. The mechanisms by which they do so remain unclear, but emerging evidence suggests that activate dendritic cells (DCs) via Toll-like receptors (TLRs). For example, the yellow fever vaccine YF-17D, one of the most successful empiric vaccines ever developed, activates DCs via multiple TLRs to stimulate pro-inflammatory cytokines. Triggering specific combinations of TLRs in DCs can induce synergistic production of cytokines, which results in enhanced T cell responses, but its impact on antibody responses remain unknown. Learning the critical parameters of innate immunity that programs such antibody responses remains a major challenge in vaccinology. We demonstrated that immunization of mice with synthetic nanoparticles containing antigens plus Toll-like receptor (TLR) ligands 4 (MPL) + 7 (R837) induces synergistic increases in antigen-specific, neutralizing antibodies compared to immunization with a single TLR ligand. To determine whether there was any early programming of B cells, we isolated isotype switched, TCRbeta-CD11b-CD19+IgD-IgG+ B cells by FACS at 7 days post immunization with nanoparticles containing various adjuvants plus OVA, and performed microarray analyses to assess their molecular signatures.

View SamplesWild-type and mouse mutants for FGF3, FGF10 and FGF3/FGF10 double mutants at embryonic day E10 were analysed by microarrays for downregulated genes. A tissue sample corresponding to an area containing the otic vesicle and surrounding mesenchyme and neighboring hindbrain were isolated from E10 embryos (See Figure 3A of manuscript). Five samples were pooled for RNA preparation. Samples were isolated from wild-type, FGF3, FGF10 and FGF3/FGF10 double mutants. Two RNA samples for each genotype were generated (corresponding to 8 tissue samples). RNA was labeled and hybridized with Affymetrix U74A V2 arrays.
