Illumina HiSeq 2000
Description
Here we report RNA-Seq data from RNA isolated from newborn lenses from FVB/N control mice as well as from newborn lenses of two different transgenic mouse lines (Le-Cre and P0-3.9GFPCre). Sequence reads of 51 bp were obtained from an illumine HiSeq 2000 system and mapped to the C57BL/6 reference genome (assembly GRCm38 (mm10)) using GSNAP software. Adapters and poor-quality regions were trimmed using Trimmomatic-0.36 software. Gene and isoform abundance was quantified using RSEM-1.3.0 software. Differential expression analysis was completed using DESeq2-1.10.1 software. For differential expression we used a cutoff value of equal to or greater than 1.5-fold change with an adjusted p value = 0.05. The transcriptomes of both Le-Cre and P0-3.9GFPCre lenses closely matched the FVB/N control lenses. However, Le-Cre lenses exhibited deregulation of 15 murine genes, several of which are associated with apoptosis. In contrast, P0-3.9GFPCre lenses only deregulated two murine genes. Overall design: Lens mRNA profiles of newborn wild type FVB/N strain, Le-Cre and P0-3.9GFPCre mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000.

Description
HepG2 and THP-1 cells, the latter differentiated by phorbol 12-myristate 13-acetate (PMA), were co-cultured and characterized for typical liver-specific functions, such as xenobiotic detoxification, lipid and cholesterol metabolism. Furthermore, liver injury-associated pathways, such as inflammation, were studied. In general, the co-cultivation of these cells produced a pro-inflammatory system, as indicated by increased levels of cytokines (IL-8, TGF-α, IL-6, GM-CSF, G-CSF, TGF-β, and hFGF) in the respective supernatant. Increased expression levels of target genes of the aryl hydrocarbon receptor (AHR), e.g., CYP1A1, CYP1A2 and CYP1B1, were detected, accompanied by the increased enzyme activity of CYP1A1. Moreover, transcriptome analyses indicated a significant upregulation of cholesterol biosynthesis, which could be reduced to baseline levels by lovastatin. In contrast, total de novo lipid synthesis was reduced in co-cultured HepG2 cells. Key events of the adverse outcome pathway (AOP) for fibrosis were activated by the co-cultivation, however, no increase in the concentration of extracellular collagen was detected. This indicates, that AOP should be used with care. In summary, the indirect co-culture of HepG2/THP 1 cells results in an increased release of pro-inflammatory cytokines, an activation of the AHR pathway and an increased enzymatic CYP1A activity.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The transcription factor MyoD can coax na?e fibroblasts or otherwise committed cells to adopt the skeletal muscle phenotype by activating the muscle gene expression program. Activation of muscle gene expression occurs in quantal steps with not all the target genes of MyoD being activated at the same time. Some genes are induced in the initial phases, others at later stages despite the fact that MyoD is present throughout the differentiation process. MyoD is post-translationally modified by phosphorylation, ubiquitination, and acetylation. Here, we have employed a model system in which MyoD and its non-acetylatable version were inducibly expressed in mouse embryonic fibroblasts derived from mice to investigate how MyoD acetylation may contribute to differential gene activation.

MyoD acetylation influences temporal patterns of skeletal muscle gene expression.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Low-oxygen tolerance is supported by an adaptive response that includes a coordinate shift in metabolism and the activation of a transcriptional program that is driven by the hypoxia-inducible factor (HIF) pathway. The precise contribution of HIF-1 in the adaptive response, however, has not been determined. Here we investigate how HIF-1 influences hypoxic adaptation throughout Drosophila development. We find that hypoxic-induced transcriptional changes are comprised of HIF-dependent and HIF-independent pathways that are distinct and separable. We show that normoxic set-points of carbohydrate metabolites are significantly altered in dHIF mutants and that these animals are unable to mobilize glycogen in hypoxia. Furthermore, we find that the estrogen-related receptor (dERR), which is a global regulator of aerobic glycolysis in larvae, is required for a competent hypoxic response. dERR binds to dHIF and participates in the HIF-dependent transcriptional program in hypoxia. In addition, dERR acts in the absence of dHIF in hypoxia and a significant portion of HIF-independent transcriptional responses can be attributed to dERR actions, including upregulation of glycolytic transcripts. These results indicate that competent hypoxic responses arise from complex interactions between HIF-dependent and -independent mechanisms, and that dERR plays a central role in both of these programs.

HIF- and non-HIF-regulated hypoxic responses require the estrogen-related receptor in Drosophila melanogaster.

- Affymetrix Mouse Gene 1.1 ST Array (mogene11st)
Description
The objective of this study was to determine the effect of Thyroid Hormone Responsive Protein Spot14 (Spot14) overexpression on the gene expression profiles of tumors from MMTV-Neu mice. Hemizygous MMTV-Neu and MMTV-Spot14 mice were bred and 1 cm tumors from Neu control or Neu/Spot14 bitransgenic offspring were profiled using Affymetrix gene arrays. Tumors from Neu/Spot14 mice emerged significantly earlier than controls, but expressed many genes associated with lactogenic differentiation and were not highly metastatic. These results from the mouse model are consistent with observations from primary human breast tumors, which indicate that high Spot14 gene expression was directly correlated with a luminal subtype and a positive ER status. Overexpression of Spot14 in cultured mammary epithelial cells stimulated proliferation but not differentiation. Together, these data suggest that, in vivo, Spot14 is expressed in well-differentiated cells, and promotes the expansion of this population in the context of oncogenic signaling pathway activation.
