Affymetrix Zebrafish Genome Array (zebrafish)
Description
We examined the transcriptional effect of preventing cardiac contraction in zebrafish embryos which can be deprived of circulation without experiencing hypoxia since the fish obtain sufficient oxygen via diffusion. Morpholino antisense knockdown of cardiac troponin T2 (tnnt2) prevented cardiac contraction without affecting vascular development. We concluded that absence of hemodynamic force induces endothelial CXCR4a up-regulation and promotes recovery of blood flow.

Microarray profiling reveals CXCR4a is downregulated by blood flow in vivo and mediates collateral formation in zebrafish embryos.

Description
Purpose:To identify resistance mechanisms for the chemotherapeutic drug fludarabine in chronic lymphocytic leukemia (CLL), as innate and acquired resistance to fludarabine-based chemotherapy represents a major challenge for long-term disease control. Methods: We employed piggyBac transposon-mediated mutagenesis, combined with next-generation sequencing, to identify genes that confer resistance to fludarabine in a human CLL cell line. Results: RNA-seq profiling of fludarabine-resistant cells suggested deregulated MAPK signaling as involved in mediating drug resistance in CLL. Overall design: To address if the fludarabine-resistant HG3 cells were transcriptionally different at a global level compared to their parental cells, we performed RNA-sequencing of three pairs of HG3 pools

Description
Gene-expression in siRNA treated U2OS and hTERT-RPE1 cells showed that CASP8AP2, NPAT and HINFP do not regulate expression of each other, and do not have any common target genes, except histones. Most histone genes are downregulated in U2OS cells following loss of CASP8AP2, NPAT or HINFP. In normal cells, highly-expressed histone genes were downregulated, albeit less than in tumor cells following loss of CASP8AP2. The p53 target genes were upregulated relatively late, clearly after the changes in expression of histone genes were observed.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Multiple sclerosis is a chronic, inflammatory, demyelinating disease of the central nervous system in which macrophages and microglia play a central role. During active multiple sclerosis foamy macrophages and microglia, containing degenerated myelin, are abundantly found in demyelinated areas. Recent studies have described an altered macrophage phenotype after myelin internalization. However, by which mechanisms myelin affects the phenotype of macrophages and how this phenotype can influence lesion progression is unclear.

Myelin-derived lipids modulate macrophage activity by liver X receptor activation.

Description
The ACBP knockout were created by targeted disruption of the gene in mice. The expression profiling was performed on liver tissue from ACBP-/- (KO) and +/+ (WT) mice at the age of 21 days, which in our study is the time immediately before weaning. The mice used for this experiment were taken directly away from their mother. Thus, having free access to chow and breast milk until sacrificed at 8-11am

Description
Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by stem cells (SCs). Following hair regeneration, SCs within the bulge and its vicinity (upper ORS which becomes the bulge for the next cycle) briefly self-renew to replenish expended SCs and ensure long-term tissue regeneration.

Description
Genome-wide RNAi screens in mice identified Ctnnb1 and Mllt6 as physiological regulators of HrasG12V-dependent epidermal hyperplasia. To probe the consequences of Ctnnb1 and Mllt6 on HrasG12V-dependent oncogenic growth, we examined how their depletion impacts gene expression in the HrasoncoX2 epidermis. We performed RNA-seq analysis of FACS-purified embryonic epidermal cells, followed by network analysis of differentially regulated transcripts. Whether Ctnnb1 or Mllt6, knockdown markedly enhanced activity of genes restricting growth, and decreased expression of genes promoting epidermal proliferation. This contrasted with known transcriptional changes that typically follow epidermal expression of oncogenic Hras. Moreover, there was a significant overlap in genes whose expression was affected by Mllt6 and ß-catenin, further implying a level of shared function. Overall design: Transcriptional profiles of epidermal progenitors of embryonic day 18.5 animals of wild-type, HrasG12V, and HrasG12V depleted of Ctnnb1 or Mllt6 backgrounds.
