View SamplesTo investigate whether U1C plays a role in splicing regulation in human system, we performed siRNA-mediated knockdown of U1C in HeLa cells and analyzed alternative splicing patterns by high-throughput RNA sequencing (RNAseq) Overall design: RNAseq performed with poly(A)+ selected total RNA from U1C-knockdown and control-treated HeLa cells

View SamplesMHC-I overexpression in muscle biopsies is a hallmark of inflammatory myopathies.However the mechanisms of MHC-I overexpression in each disease is not well understood. Microarray analysis from MHC-I-microdissected myofibers showed a differential expression signature in each inflammatory myopathy. Innate immunity and IFN-I pathways are upregulated vs healthy controls, specifically in dermatomyositis (DM).

View SamplesClaudin-16 deficiency leads to renal salt wasting in humans and mice. Analysis of renal gene expression in Claudin-16 deficient mice, compared to heterozygous and wild type littermates, was performed to gain insights into molecular mechanisms compensating salt loss. Our results indicate the upregulation of known and putative genes for renal transcellular transporters. Furthermore, we could identify a transcript so far not associated with renal salt metabolism, which will provide a first link to a human electrolyte disorder disease.

View SamplesCutaneous T-cell lymphoma (CTCL) develops from clonally expanded CD4+ T cells in a background of chronic inflammation. Dendritic cells (DCs) are potent T-cell stimulators; yet despite DCs' extensive presence in skin, cutaneous T cells in CTCL do not respond with effective anti-tumor immunity. We evaluated primary T-cell and DC émigrés from epidermal and dermal explant cultures of skin biopsies from CTCL patients (n = 37) and healthy donors (n = 5). Compared with healthy skin, CD4+ CTCL populations contained more T cells expressing PD-1, CTLA-4, and LAG-3; and CD8+ CTCL populations comprised more T cells expressing CTLA-4 and LAG-3. CTCL populations also contained more T cells expressing the inducible T-cell costimulator (ICOS), a marker of T-cell activation. DC émigrés from healthy or CTCL skin biopsies expressed PD-L1, indicating that maturation during migration resulted in PD-L1 expression irrespective of disease. Most T cells did not express PD-L1. Using skin samples from 49 additional CTCL patients for an unsupervised analysis of genome-wide mRNA expression profiles corroborated that advanced T3/T4 stage samples expressed higher levels of checkpoint inhibition genes compared with T1/T2 stage patients or healthy controls. Exhaustion of activated T cells is therefore a hallmark of both CD4+ and CD8+ T cells directly isolated from the lesional skin of patients with CTCL, with a continuum of increasing expression in more advanced stages of disease. These results justify identification of antigens driving T-cell exhaustion and the evaluation of immune checkpoint inhibition to reverse T-cell exhaustion earlier in the treatment of CTCL. Overall design: RNA-seq correlated with tumor stages

View SamplesWe have investigated the regulation of anchorage-independent growth (AIG) by basic fibroblast growth factor (bFGF) and 12-O-tetradecanoyl phorbol-13-acetate (TPA) in JB6 mouse epidermal cells in the context of wound repair versus carcinogenesis responses. bFGF induces an unusually efficient but reversible AIG response, relative to TPA-induced AIG which is irreversible. Distinct global gene expression profiles are associated with anchorage-independent colonies arising from bFGF-stimulated JB6 cells, relative to colonies arising from fully tumorigenic JB6 cells (RT101), including genes exhibiting reciprocal regulation patterns. Thus, while TPA exposure results in commitment to an irreversible and tumorigenic AIG phenotype, the AIG response to bFGF is reversible with essentially complete restoration of normal cell cycle check point control following removal of bFGF from growth medium. These results are consistent with the physiological role of bFGF in promoting wound healing, and suggest that natural mechanisms exist to reverse transformative cellular phenotypes associated with carcinogenesis.

View SamplesUsing a macrophage cell line, we demonstrate the ability of amorphous silica particles to stimulate inflammatory protein secretion and induce cytotoxicity. Whole genome microarray analysis of early gene expression changes induced by 10nm and 500nm particles showed that the magnitude of change for the majority of genes correlated more tightly with particle surface area than either particle mass or number. Gene expression changes that were size-specific were also identified, however the overall biological processes represented by all gene expression changes were nearly identical, irrespective of particle diameter. Our results suggest that on an equivalent nominal surface area basis, common biological modes of action are expected for nano- and supranano-sized silica particles.
Macrophage responses to silica nanoparticles are highly conserved across particle sizes.
