Description
c-Fos, a member of the stress-activated Activator Protein 1 (AP-1) transcription factor family, is expressed in human hepatocellular cancer (HCC). Using genetically engineered mouse models (GEMMs) we show that hepatocyte-specific expression of c-Fos leads to a proliferative, de-differentiated phenotype, whereas hepatocyte-specific deletion of c-Fos protects against diethylnitrosamine (DEN)-induced liver cancer. Furthermore, c-Fos-expressing livers resemble human HCCs based on expression profiles. In the present RNA seq, we intend to analyze the transcriptomic profile of livers at 2 and 4 mo hepatocyte-specific c-Fos expression compared to the corresponding age-matched control mice. Moreover, we analyzed livers of mice with hepatocyte-specific deletion c-Fos at 48h after DEN treatment compared to identically treated control mice. Overall design: The general idea was to analyze the transcriptomic profile of hepatocyte-specific c-Fos over-expressing livers at 2 and 4 mo expression. Hereby, a hepatocyte-specific doxycycline (Dox)-switchable mouse model was (LAP-tTA; col1a1:Tet-O-fosFlag) was generated and c-Fos expression was induced at the age of 3 weeks by removal of doxycycline. Each sample LaptTA-fos-MUT represents an individual hepatocyte-specific c-fos expressing mouse at the indicated time-point and the corresponding identically treated control mouse LaptTA-fos-CO. Moreover, the transcriptomic profile of livers with hepatocyte-specific deletion of c-Fos at 48h after diethylnitrosamine (DEN)-induced liver cancer initiation was analyzed. For hepatocyte-specific knock-out of c-Fos, mice with conditional alleles of c-fos and the Alfp-Cre transgene were used. Control mice only carried the Alfp-Cre transgene. At the age of 8 weeks these mice were injected with 100mg/kg DEN. Each sample AlfpCre-fos-MUT_DEN represents an individual hepatocyte-specific c-fos knock-out mouse 48h after DEN and the identically treated control mouse AlfpCre-fos-CO-Cre+_DEN.

Description
The Drosha-DGCR8 complex (Microprocessor) is required for microRNA (miRNA) biogenesis. DGCR8 contains two double-stranded RNA binding motifs that recognize the RNA substrate, whereas Drosha functions as the endonuclease. We have used high-throughput sequencing of RNAs isolated by crosslinking immunoprecipitation (HITS-CLIP) to identify endogenous RNA targets of DGCR8 in mammalian cells. Unexpectedly, miRNAs were not the most abundant targets. DGCR8-bound RNAs comprised several hundred mRNAs as well as snoRNAs and long non-coding RNAs. We found that DGCR8 together with Drosha controls the abundance of several mRNAs, as well as long non-coding RNAs, such as MALAT-1. By contrast, the DGCR8-mediated cleavage of snoRNAs is independent of Drosha, suggesting the involvement of DGCR8 in cellular complexes with other endonucleases. Interestingly, binding of DGCR8 to cassette exons, acts as a novel mechanism to regulate the relative abundance of alternatively spliced isoforms. Collectively, these data provide new insights in the complex role of DGCR8 in controlling the fate of several classes of RNAs. Overall design: Comparison of RNAs associated to both endogenous (D8) and overexpressed (T7) DGCR8 in HEK293T cells

Description
Cystic Fibrosis lung disease progresses by a combination of accelerated airways inflammation and bacterial colonization and infection. Airways inflammation in CF is predominantly neutrophilic and complicates airway clearance therapies through cellular debris, excessive DNA, excessive and viscous mucous, and high concentrations of neutrophils,Il-8 and related cytokines liberated along the NFkB signaling pathway. We conducted a single site, randomized, double blind, placebo-controlled, proof-of-concept trial in which we evaluated the effects of 28 days of two dose levels (0.05 mg and 0.10 mg daily) of an older cardiac glycoside, digitoxin, as compared with placebo, on inflammatory markers in induced sputum obtained from 24 subjects with mild to moderate CF lung disease. Nasal epithelial cells from 23 subjects were analyzed for microarray analysis. CF patients 18 to 45 years old, any genotype combination, were eligible.

Description
U1 small nuclear (sn)RNA, required for splicing of pre-mRNA, is encoded by genes on chromosome 1p36. Imperfect copies of these true (t)U1 snRNA genes, located on chromosome 1q12-21, were thought to be pseudogenes. However, many of these variant (v)U1 snRNA genes produce fully-processed transcripts that are packaged into potentially functional particles. Using antisense oligonucleotides, we have achieved functional knockdown of a specific vU1 snRNA in HeLa cells and identified over 400 transcriptome changes following interrogation of the Affymetrix Human Exon ST 1.0 array.

Differentially expressed, variant U1 snRNAs regulate gene expression in human cells.

Description
IL-6, a proinflammtory cytokine produced by antigen presenting cells and non-hematopoietic cells in response to external stimuli, acts as an important bridge between the innate and adaptive immune responses. IL-6 together with IL-4 can promote Th2 polarization, while in combination with TGFbeta mediates Th17 differentiation. We examined early changes in gene expression in mouse CD4+ T cells induced by IL-6.
Publication Title
The induction of antibody production by IL-6 is indirectly mediated by IL-21 produced by CD4+ T cells.
