Description
We analyzed gene expression profiles of self-organizing, multi-cellular, 3D liver organoids derived by co-culture of induced Pluripotent Stem Cell and stromal progenitors. We report the RNA-seq results of liver organoid at day0, day2, day4, day6 of co-culture. We also report RNA-seq results of constituent of the liver organoid, which are human iPSC at hepatic specification stage, human Mesenchymal stem cells derived from bone marrow, human umbilical vein endothelial cell. As controls, we also report RNS-seq results of un-differentiated human iPSC, human iPSC at definitive endoderm stage, human liver tissue, and primary cultured human hepatocytes isolated from unused donor livers. Overall design: mRNA profiles of liver organoids and their constituents were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500.

Description
To understand the function and regulation of the C. elegans heat shock factor (HSF-1) in larval development, we have used ChIP-seq to analyze the occupancy of HSF1 and RNA Pol II in L2 larvae and young adult (YA) animals grown at 20°C or upon heat shock at 34°C for 30 min. In addition, we have used RNA-seq to analyze the transcriptomes of wild type (N2), hsf-1(ok600) mutants and hsf-1(ok600); rmSi1[hsf-1::gfp] L2 larvae grown at 20°C and characterized the gene expression change by heat shock in wild type (N2) animals at L2 stage. Overall design: Experiment type: RNA-seq. Biological Source: strain: N2, OG576, AM1061; developmental dtage: L2 Larva. Experimental Factors: temperature: 20 degree celsius.

Description
Purpose: The goals of this study are to compare transcriptome profiling (RNA-seq) resulting from a Mesp1Cre driven ablation of Hira in the heart at E11.5 and E12.5. Methods: RNA extraction was done in triplicate from Mesp1Cre;Hira-/fl and Mesp1Cre;Hira+/fl embryonic hearts at E11.5 and E12.5 using the QIAGEN RNeasy mini kit. RNAseq was processed by the ICH genomics facility, reads were aligned and normalised using BOWTIE and DEseq R package. Strand NGS 2.5 software was used to re-analyse the aligned files (.bam). By applying the Mann Whitney unpaired test, Benjamini Hochberg False discovery rate (FDR) and filtering the genes using adjusted p-value = 0.05 and absolute fold change = 1.5, 95 % of the results were identical to the DEseq package used by the UCL Genomics facility. Results: We identified 360 coding transcripts changed in the mutant hearts (Mann Whitney unpaired test, Benjamini Hochberg FDR, p = 0.05, FC = 1.5) with no trend towards up- or down-regulation of global transcription (48.8% down vs 51.2% up) at E12.5. Conclusions: This work analyses the role of HIRA in mouse cardiac development. It was found that Tnni2 is the most upregulated gene in the absence of Hira. qRT-PCR validation of 25 targets. Little (<5%) or no variation of fold change between RNAseq and qRT-PCR data were observed. Overall design: Cardiac mRNA profiles of 11-day and 12-day embryonic days Mesp1Cre control (Ctrl) and Mesp1Cre;Hira-/fl (mut) were generated by deep sequencing, in triplicate, using Illumina GAIIx.

Description
Background: Thiazolidinediones (TZDs) activate peroxisome proliferator-activated receptor gamma (PPARgamma) and are used clinically to help restore peripheral insulin sensitivity in Type 2 diabetes (T2DM). Interestingly, long-term treatment of mouse models of Alzheimers disease (AD) with TZDs also has been shown to reduce several well-established brain biomarkers of AD including inflammation, oxidative stress and Abeta accumulation. While some of the TZD actions are becoming clear in AD models and may mediate their reported beneficial impact in AD patients, little is known about the functional consequences of TZDs in animal models of normal aging. Because aging is a common risk factor for both AD and T2DM, we investigated whether the TZD, pioglitazone could alter brain aging under non-pathological conditions. Findings: The TZD pioglitazone (PIO) was incorporated into the diet to yield a final dose of approximately 2.3 mg/kg body weight/day. PIO reduced insulin levels irrespective of age. Interestingly, a significant reduction in the Ca2+-dependent afterhyperpolarization was seen in the aged animals with no significant change in LTP maintenance or learning and memory performance. Finally, a combination of microarray analyses on hippocampal tissue and serum-based multiplex cytokine assays revealed that age-dependent inflammatory changes in brain and periphery were not reversed by PIO.

Description
Thiazolidinediones (TZDs) are agonists at peroxisome proliferator-activated gamma-type (PPAR-y) receptors and are used clinically for the treatment of type 2 diabetes where they have been shown to reestablish insulin sensitivity, improve lipids profile, and reduce inflammation. Recent work also suggests that TZDs may be beneficial in Alzheimer's disease (AD), ameliorating cognitive decline early in the disease process. However, there have been only a few studies identifying mechanisms through which cognitive benefits may be exerted. Starting at 10 months of age, the triple transgenic mouse model of AD (3xTg-AD) with accelerated amyloid-B (AB) deposition and tau pathology was treated with the TZD pioglitazone (PIO- Actos) at 18 mg/Kg body weight/day. After four months, PIO-treated animals showed multiple beneficial effects, including improved learning on the active avoidance task, reduced serum cholesterol, decreased hippocampal AB deposits, and enhanced short- and long-term plasticity. Baseline electrophysiological membrane properties and blood glucose levels were unchanged by PIO treatment. Gene microarray analyses of hippocampal tissue identified predicted transcriptional responses following TZD treatment as well as potentially novel targets of TZDs, including facilitation of estrogenic processes, and decreases in glutamatergic and ketone metabolic/ cholesterol dependent processes. Taken together, these results confirm prior animal studies showing that TZDs can ameliorate cognitive deficits associated with AD-related pathology, but also extend these findings by pointing to novel molecular targets in the brain.
