Affymetrix Human Genome U133A Array (hgu133a)
Description
The pigmented portion of ciliary epithelium in the adult mammalian eye harbors mitotically quiescent retinal sphere cells, which are capable of self-renewal and differentiating into retinal neurons when assayed in vitro; however, very little is known about the molecular mechanism controlling the proliferation and differentiation of these adult retinal stem cells or their molecular resemblance to mutipotent stem/progenitor cells during early eye development. This experiment studies the gene expression of first passage and primary human and mouse retinal sphere cells.

Description
Spinal cord injury leads to impaired motor and sensory functions. After spinal cord injury there is a an initial phase of hypo-reflexia followed by a developing hyper-reflexia, often termed spasticity. Previous studies have suggested a relationship between the reappearence of plateau potentials in motor neurons and the development of spasticity after spinalizaion. To understand the moleclar mechanism behind this pheneomona we examined the transcriptional response of the motor neurons after spinal cord injury as it progress over time.

Description
The MYC transcription factor is a master regulator of diverse cancer pathways and somatic cell reprogramming. MYC is a compelling therapeutic target that exhibits cancer-specific cellular effects. Pharmacologic inhibition of MYC function has proven challenging due to its numerous modes of forced expression and the difficulty of disrupting protein-DNA interactions. Here we demonstrate the rapid and potent abrogation of MYC gene transcription by representative small molecule bromodomain inhibitors of the BET family of chromatin adaptors. This transcriptional suppression of MYC was observed in the context of the natural, chromosomally translocated, and amplified gene locus. Inhibition of BET bromodomain-promoter interactions and subsequent reduction of MYC transcript and protein levels resulted in G1 arrest and extensive apoptosis in a variety of leukemia and lymphoma cell lines. Exogenous expression of MYC from an artificial promoter that is resistant to BET regulation significantly protected cells from growth suppression by BET inhibitors and revealed that MYC exerts a direct and tight control of key pro-growth and anti-apoptotic target genes. Transcriptional profiling of two cells after 4 and 8 hours of treatment with BET inhibitor shows that both MYC and its targets are strongly down-regulated. We thus demonstrate that pharmacologic inhibition of MYC is achievable through targeting BET bromodomains, and suggest that such inhibitors may have broad clinical applicability given the widespread pathogenetic role of MYC in cancer.

Description
The mammary gland develops mainly postnatally, when during pregnancy the epithelium grows out into the mammary fat pad and forms a network of epithelial ducts. During pregnancy, these ducts branch and bud to form alveoli. These alveoli produce the milk during lactation. After 7 days of lactation, involution was induced by force weaning the pups. The newly formed epithelium undergoes apoptosis and is removed from the tissue by neighbouring epithelial cells. Tissue remodelling leads to a morphology resembling a gland of a pre-pregnant mouse. Microarray analysis was used to measure mRNA expression of genes during puberty, pregnancy, lactation and involution in a Balb/c mouse strain.
Publication Title
Involution of the mouse mammary gland is associated with an immune cascade and an acute-phase response, involving LBP, CD14 and STAT3.

Description
Purpose: Identify whole lung gene expression patterns in a house dust mite model of mild/moderate asthma Methods: Lung gene expression profiles of 10 week old BALB/c female mice were generated by ribosome-depleted, 150 nt, paired-end, stranded RNA-seq with Illumina HiSeq v4. Sequence reads that passed quality filters after trimming were analyzed with Sailfish-cir to identify linear RNAs and circular RNAs. Differential expression of linear RNAs was assessed with Deseq2 . QRT–PCR validation was performed using TaqMan and SYBR Green methods. Results: 100 million sequence reads per sample were mapped to the mouse genome (build mm10) using Sailfish-cir to identify linear and circular RNA transcripts. Pathway analysis of differentially expressed genes identified upregulation of gene sets for human asthma, mouse lung allergic inflammation, Muc5ac regulated genes and smooth muscle genes after allergic sensitization. Gene level exppression in each asthma-related pathway was reduced by the miR-145 antagonist. The miR-145 antagonist and several nontargeting oligos also upregulated interferon signaling pathways suggesting a general antiinflammatory effect of LNA/DNA oligos in the lung. Conclusions: Lung-directed delivery of LNA/DNA oligonucleotides with cationic lipid nanoparticles is an efffective means to prevent inflammatory gene expression in a house dust mite model of mild/moderate asthma. Overall design: Linear and circular RNA transcript expression was compared in whole lung tissue from unsensitized, house dust mite sensitzed, antimiR-145 treated treated mice

Purpose: Identify whole lung gene expression patterns modified by nanoparticle delivery of an antisense LNA/DNA oligonucleotide targeting mmu-miR145a-5p and nontargeting oligonucleotides Methods: Lung gene expression profiles of 10 week old BALB/c female mice were generated by polyA RNA-seq with Illumina HiSeq v4. Sequence reads that passed quality filters after timming were analyzed at the gene level with RNA STAR, featureCounts and Deseq2 . qRT–PCR validation was performed using TaqMan and SYBR Green methods. Results: 10-15 million sequence reads per sample were mapped to the mouse genome (build mm10). Pathway analysis of differentially expressed genes identified upregulation of gene sets for human asthma, mouse lung allergic inflammation, Muc5ac regulated genes and smooth muscle genes after allergic sensitization.

Description
Gene expression programs change during cellular transitions. It is well established that a network of transcription factors and chromatin modifiers regulate RNA levels during embryonic stem cell (ESC) differentiation, but the full impact of post-transcriptional processes remains elusive. While cytoplasmic RNA turnover mechanisms have been implicated in differentiation, the contribution of nuclear RNA decay has not been investigated. Here, we differentiate mouse ESCs, depleted for the ribonucleolytic RNA exosome, into embryoid bodies to determine to which degree RNA abundance in the two states can be attributed to changes in transcription vs. RNA decay by the exosome. As a general observation, we find that exosome depletion mainly leads to the stabilization of RNAs from lowly transcribed loci, including several protein-coding genes. In particular, transcripts that are differentially expressed between states tend to be more exosome sensitive in the state where expression is low. We conclude that the RNA exosome contributes to down-regulation of transcripts with disparate expression, often in conjunction with transcriptional down-regulation. Overall design: CAGE experiments were carried out in mouse embryonic stem cells and embryoid bodies differentiated for three days upon depletion of RRP40 with shRNAs, using a scrambled shRNA as control. The experiments were performed in duplicates
