Description
We are daily exposed to a multitude of health hazardous airborne particulate matter with notable deposition in the fragile alveolar region of our lungs. Hence, there is a great need for identification and prediction of material-associated diseases, currently hindered due to the lack of in-depth understanding of causal relationships, in particular between acute exposures and chronic symptoms. By applying advanced microscopies and omics to in vitro and in vivo systems, together with in silico molecular modelling, we have here determined that the long-lasting response to a single exposure can originate from the interplay between the newly discovered nanomaterial quarantining and nanomaterial cycling between different lung cell types. This new insight finally allows us to predict the spectrum of lung inflammation associated with materials of interest using only in vitro measurements and in silico modelling potentially relating outcomes to material properties for large number of materials thus boosting safe-by-design-based material development. Because of its profound implications for animal-free predictive toxicology, our work paves the way to a more efficient and hazard-free introduction of numerous new advanced materials into our lives.

Description
Background: Although genome-wide association studies (GWAS) have identified hundreds of variants associated with risk of autoimmune and immune-related disorders (AID), our understanding of the diseases mechanisms is limited. In particular, more than 90% of the risk variants lie in non-coding regions, and almost 10% of these map to long non-coding RNA transcripts (lncRNAs). LncRNAs are known to show more cell-type specificity than protein-coding genes. Methods: In this study, we aimed to characterize lncRNAs and protein-coding genes located in loci associated with nine AID which have been well-defined by Immunochip analysis, by transcriptome analysis across seven peripheral blood leukocyte populations (granulocytes, monocytes, NK cells, B-cells, memory-T cells, naive CD4+ and naive CD8+ T-cells) and four cord blood derived T-helper cell populations (precursor, primary, polarized (Th1, Th2) T-helper cells). Results: We show that lncRNAs mapping to loci shared between AIDs are significantly enriched in immune cell types when compared to lncRNAs from the whole genome (a<0.005). We were not able to prioritize single cell types relevant for specific diseases, but we observed five cell types enriched (a<0.005) in five AID (NK cells for inflammatory bowel disease, juvenile idiopathic arthritis, primary biliary cirrhosis, psoriasis; memory-T and CD8+ T-cells in juvenile idiopathic arthritis, primary biliary cirrhosis, psoriasis, rheumatoid arthritis; Th0 and Th2 cells for inflammatory bowel disease, juvenile idiopathic arthritis, primary biliary cirrhosis, psoriasis, rheumatoid arthritis). Furthermore we show that co-expression analyses of lncRNAs and protein-coding genes can predict the signaling pathways in which these AID-associated lncRNAs are involved. Conclusions: The observed enrichment of lncRNA transcripts in AID loci implies an important role for lncRNAs in AID etiology and suggests that lncRNA genes should be studied in more detail to correctly interpret GWAS findings. The co-expression results strongly support a model in which the lncRNA and protein-coding genes function together in the same pathways. Overall design: 7 immune cell types

Description
We report the transcriptional response of the zebrafish digestive organs to an acute high-fat feed using RNASeq analysis and highlight the changes in gene expression involved in the synthesis, storage, and dispersal of lipids. These key physiological responses to a high-fat meal all stem from the endoplasmic reticulum (ER), where lipids are formed and assigned to their fates. Overall design: A feeding time course was undertaken with 6.5-dpf larval zebrafish. Triplicate samples were independently prepared from pairwise crosses fed either high-fat or low-fat food. 5% egg yolk emulsion (high-fat) feeds and 10% egg white (low-fat) feeds were prepared. At the appropriate time points, digestive organs (intestine, liver, pancreas) were dissected from 10 anesthetized larval zebrafish. Unfed controls were used to determine a transcriptional baseline.

Description
Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using transcriptome profiling (RNA-seq) to evaluate the effects of EBV infection or (and) EBV BART6-3p mimics on the global transcriptome of the BJAB cells. Methods: BJAB cells were transfected with negative control mimics or BART6-3p mimics for 48 h and then infected with EBV virons for 2h. RNAs were extracted by Trizol and sequenced by Solexa high-throughput sequencing service (Oebiotech, Shanghai, China). Data were extracted and normalized according to the manufacturer's standard protocol. Results: Log-fold changes of up- or down-regulated mRNAs between the control and experiment group were selected with a significance threshold of p<0.05. There are 408 mRNAs were up-regulated and 263 were down-regulated in “EBV infection” group cells comparing to “Mock” group cells. There are 385 mRNAs were up-regulated and 246 were down-regulated in “EBV infection + Bart6-3p mimics” group cells comparing to “EBV infection + negative control mimics” group cells. Conclusions: Our study describes the global transciptome changes of BJAB cells induced by EBV infection or (and) EBV 6-3p mimics. Overall design: BJAB cells mRNA profiles of “mock” (no infection, no treatment), “EBV infection”, “EBV infection + negative control mimics”, and “EBV infection + BART6-3p mimics” were generated by RNA sequecning, using Solexa high-throughput sequencing service (Oebiotech, Shanghai, China).

Description
Lamins, the major components of the nuclear lamina, have diverse functions in many cellular processes. Despite broad expression, lamins have been implicated in cell type-specific roles in development, aging and disease by regulating gene expression. Yet, due to the lack of in depth lineage-specific functional studies, it remains unclear whether or how lamins regulate cell type-specific functions. Using targeted knockout of lamin B1 in the olfactory sensory neuron lineage, we show that lamin B1 is not required for early stages of olfactory sensory neuron differentiation but is needed for formation of mature neurons that properly respond to odor stimulation. Lamin B1 mutant cells exhibited decreased expression of genes involved in mature neuron function, increased expression of genes atypical of the olfactory lineage and clustered nuclear pore distribution. These results demonstrate that the universally expressed lamin B1 regulates cell type-specific gene expression and terminal differentiation. Overall design: Transcriptome profiles were generated from sorted regenerated olfactory epithelium cells lacking Lamin B1 (Lmnb1) and control (heterozygous cells). Each sample is collected from one mouse. Data are from two experimental groups (G1,G2), each containing a control and a mutant sample. Different groups differ in treatment, parents, age and sex. Within a group, treatment, sample preparation, sequencing, animal sex, age, and parents are the same.
