Genome-wide RNA polymerase II profiles and RNA accumulation reveal kinetics of transcription and associated epigenetic changes during diurnal cycles.

View SamplesCyclic regulatory systems are ubiquitous in cells and tissues. In the liver rhythms in mRNA expression are determined by the homeostatic regulation that operates on daily circumstances. In particular the specific response to nutrients, as well as systemic and peripheral circadian oscillators, contribute to the set up of the hepatic homeostasis at different phases of the day. In this series we used microarrays to detail the global program of gene expression in the mouse liver under physiological daily variations, determined by both the feeding and the circadian cycles.

View SamplesAstrocytes were purified from postnatal day 2 mouse cortices by immunopanning with HepaCAM. Inhibitors and DMSO were added on in-vitro day 2. HBEGF was depleted on the cell prep day and till in-vitro day 7. In-vitro day 2, 7 and 14 samples were collected on designed timepointed. Overall design: Three EGFR inhibitor samples and three relative DMSO control samples, three P53 inhibitor samples and three relative DMSO control samples, two HBEGF samples and two HBEGF withdrawal samples, three samples for each in-vitro day 2, 7 and 14.
Astrocyte-to-astrocyte contact and a positive feedback loop of growth factor signaling regulate astrocyte maturation.

View SamplesWe describe a function of focal adhesion kinase (FAK) in driving anti-tumor immune evasion. The kinase activity of nuclear-targeted FAK in squamous cancer cells drives exhaustion of CD8+ T-cells and recruitment of regulatory T-cells by transcriptionally regulating chemokine/cytokine and ligand-receptor networks, including transcription of Ccl5 that is crucial. These changes inhibit antigen-primed cytotoxic CD8+ T-cell activity, permitting growth of FAK-expressing tumors.
Nuclear FAK controls chemokine transcription, Tregs, and evasion of anti-tumor immunity.

View SamplesHere we show that the histone methyltransferase MLL4 (Kmt2d) is required for stem cell activity and an aggressive form of acute myeloid leukemia (AML) harboring the MLL-AF9 oncogene. MLL4 exerts its function by regulating transcriptional programs associated with the anti-oxidant response. Overall design: The role of Mll4 (Kmt2d) in regulating the transcriptome of primary and transformed hematopoietic stem cells was studied.

View SamplesPlants of Arabidopsis thaliana (ecotype Col-0, nrb4-2 and nrb4-4) were grown in phytochambers in short day conditions during three weeks. Then, samples from different pots were mixed, and the RNA extracted.
Non-recognition-of-BTH4, an Arabidopsis mediator subunit homolog, is necessary for development and response to salicylic acid.

View SamplesThe anthracycline, doxorubicin (Dox), is widely used in oncology, but it may it may cause a cardiomyopathy which has dismal prognosis and cannot be effectively prevented. The secretome of multipotent human amniotic fluid-derived stem cells (hAFS) has previously been demonstrated to reduce ischemic cardiac damage. Here, it is shown that the hAFS conditioned medium (hAFS-CM) antagonizes senescence and apoptosis of cardiomyocytes and cardiac progenitor cells, two major features of Dox cardiotoxicity. Mechanistic studies with primary mouse neonatal cardiomyocytes reveal that hAFS-CM inhibition of Dox-elicited senescence and apoptosis is paralleled by decreased DNA damage and is associated with nuclear translocation of NF-kB and upregulation of a set of genes controlled by NF-kB, namely Il6 and Cxcl1, which promote cardiomyocyte survival, and Cyp1b1 and Abcb1, which encode for proteins involved in Dox metabolism and efflux, respectively. The PI3K/Akt signaling cascade, upstream of NF-kB, is potently activated by the hAFS-CM and pre-treatment with a PI3K inhibitor abrogates NF-kB accumulation into the nucleus, modulation of its target genes, and prevention of Dox-initiated senescence and apoptosis in response to the hAFS-CM. This work may lay the ground for the development of a stem cell-based paracrine therapy of chemotherapy-related cardiotoxicity.
The human amniotic fluid stem cell secretome effectively counteracts doxorubicin-induced cardiotoxicity.

View SamplesResting B cells were isolated from WT or KMTD KO mice by immunomagentic depletion of with anti-CD43 beads. Gene expression use determined by RNAseq in resting B cells or B cells stimulated with LPS, IL4, and anti-mouse CD180 for 3 days. Overall design: RNAseq was used to profile unstimulated resting B cells (n=3) and B cells stimulated for 3 days (n=3).
