Description
The conserved RNA-binding protein Musashi1 (MSI1) has emerged as a key oncogenic factor in numerous solid tumors, including glioblastoma. However, its mechanism of action has not yet been established comprehensively. We set out to map its impact on the transcriptome in U251 cells using RNA-seq and iCLIP. Overall design: Examination of gene expression and splicing changes upon KD of Musashi1 in U251 cells and link to iCLIP-identified Musashi1 RNA binding sites

We used microarrays to investigate differential gene expression in HEK293T cells after transfection of the transgene of Iroquois 1 (IRX1). Microarray analysis revealed differential gene expression patterns of HEK293T cells after transient expression of IRX1. In total 8400 genes were deregulated by IRX1.

Description
Purpose: We performed a time-course single-cell RNA-seq of the somatic cells of the XX mouse gonads to study the cell population heterogeneity and the genetic program during their differentiation. Methods: We collected gonads from NR5A1-eGFP transgenic embryos at six embryonic stages: E10.5, E11.5, E12.5, E13.5, E16.5 and P6. Methods: Cells were capture with the C1 autoprep system and cDNA sequenced with Illumina HiSeq 2000. Results: One cell population was detected at E10.5 and give rise to both Granulosa and steroidogenic precursor cells. A precursor cell population remains undifferentiated at P6 and are likely to be theca cell precursors. Conclusion: Our study is, to date, the most granular transcriptomic study of the developing mouse ovary and provide a more complete model of somatic cell differentiation during female sex determination. Overall design: 663 cells were collected in total. 71 cells at E10.5, 106 cells at E11.5, 164 cells at E12.5, 106 cells at E13.5, 95 cells at E16.5, and 121 at P6. We performed two independent captures for each embryonic stage to reach a reasonable number of cells except for E10.5 where we capture enough cells in one experiment.

Description
Eicosanoids are potent regulators of gene expression of inflammatory cells. Pro- (leukotrienes B4 and C4) and anti-indflammatory (lipoxins A4 and B4) eicosanoids have been described in the literature but the detailed impact of these lipid mediators on the gene expression pattern of monocytic cells has not been studied in detail. We cultured the permanent monocytic cell line MonoMac 6 for 12 h in the absence (solvent control) and presence of these eicosanoids and quantified the differential gene expression patterns using the microarray technology.

Description
41 volunteers (male non-smokers) were exposed to formaldehyde (FA) vapors for 4 h per day over a period of 5 working days under strictly controlled conditions. For each exposure day, different exposure concentrations were used in a random order ranging from 0 up to 0.7 ppm. At concentrations of 0.3 ppm and 0.4 ppm, four peaks of 0.6 or 0.8 ppm for 15 min each were applied. During exposure, subjects had to perform bicycle exercises (about 80 W) four times for 15 min. Blood samples, exfoliated nasal mucosa cells and nasal biopsies were taken before the first and after the last exposure. Nasal epithelial cells were additionally sampled 1, 2 and 3 weeks after the end of the exposure period. The alkaline comet assay, the sister chromatid exchange (SCE) test and the cytokinesis-block micronucleus test (CBMNT) were performed with blood samples. The micronucleus test (MNT) was also performed with exfoliated nasal mucosa cells. The expression (mRNA level) of the GSH-dependent formaldehyde dehydrogenase (FDH, identical to alcohol dehydrogenase 5; ADH5; EC 1.2.1.46) was measured in blood samples by quantitative real-time RT-PCR with TaqMan probes. DNA microarray analyses using a full-genome human microarray were performed on blood samples and nasal biopsies of selected subgroups with the highest FA exposure at different days. None of the tests performed showed a biologically significant effect related to FA exposure. Under the experimental conditions of this study, inhalation of FA did not lead to genotoxic effects in peripheral blood cells and nasal mucosa and had no effect on the expression of the FDH gene. Inhalation of FA also did not cause biologically relevant alterations in the expression of genes in a microarray analysis with nasal biopsies and peripheral blood cells.

Description
Regulation of mRNA stability by RNA-protein interactions contributes significantly to quantitative aspects of gene expression. We have identified potential mRNA targets of the AU-rich element binding protein AUF1. Myc-tagged AUF1 p42 was induced in mouse NIH-3T3 cells and RNA-protein complexes isolated using anti-myc tag antibody beads. Bound mRNAs were analyzed with Affymetrix microarrays. We have identified 508 potential target mRNAs that were at least 3-fold enriched compared to control cells without myc-AUF1. 22.3% of the enriched mRNAs had an AU-rich cluster in the ARED Organism database, against 16.3% of non-enriched control mRNAs. The enrichment towards AU-rich elements was also visible by AREScore with an average value of 5.2 in the enriched mRNAs versus 4.2 in the control group. Yet, many mRNAs were enriched without a high ARE score suggesting that AUF1 has a broader binding spectrum than standard AUUUA repeats. AUF1 did not preferentially bind to unstable mRNAs. Still, some enriched mRNAs were highly unstable, as those of TNFSF11 (known as RANKL), KLF10, HES1, CCNT2, SMAD6, and BCL6. We have mapped some of the instability determinants. HES1 mRNA appeared to have a coding region determinant. Detailed analysis of the RANKL and BCL6 3UTR revealed for both that full instability required two elements, which are conserved in evolution. In RANKL mRNA both elements are AU-rich and separated by 30 bases, while in BCL6 mRNA one is AU-rich and 60 bases from a non AU-rich element that potentially forms a stem-loop structure.
Publication Title
Short-lived AUF1 p42-binding mRNAs of RANKL and BCL6 have two distinct instability elements each.
