Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
Livers from 15 month old mice mainatined on one of 25 different diets varying in protein, carbohydrate, fat (P,C,F) and energy content were analysed. Energy content was categorised as low (8kJ/g), medium (13kJ/g) or high (17kJ/g) Mice were placed on diet from 3 weeks of age and a subset culled for various analyses. The rest of the cohort was allowed to live out their natural life to assess lifespan.

Description
Elevated branched chain amino acids (BCAAs) are associated with obesity and insulin resistance. How long-term dietary BCAAs impact late-life health and lifespan is unknown. Here, we show that when dietary BCAAs are varied against a fixed, isocaloric macronutrient background, long-term exposure to high BCAA diets led to hyperphagia, obesity and reduced lifespan. These effects were not due to elevated BCAA per se or hepatic mTOR activation, but rather the shift in balance between dietary BCAAs and other AAs, notably tryptophan and threonine. Increasing the ratio of BCAAs to these AAs resulted in hyperphagia and was linked to central serotonin depletion. Preventing hyperphagia by calorie restriction or pair-feeding averted the health costs of a high BCAA diet. Our data highlight a role for amino acid quality in energy balance and show that health costs of chronic high BCAA intakes were not due to intrinsic toxicity; rather, to hyperphagia driven by AA imbalance. Overall design: 3 animals per sex per diet were used. Mice were fed one of four diets (all 19% total protein, 63% carbohydrate, 18% fat, total energy density 14 kJ/g) varying in BCAA content (BCAA200: twice BCAA content of control diet AIN93G; BCAA100: standard content of BCAAs; and BCAA50 and BCAA20: containing one half and one fifth of standard content of BCAAs), and either euthanized at 15 months of age or maintained for determination of lifespan.

Description
Analysis of global gene expression in myeloid cells infiltrating tumors after irradiation. Cell death induces recruitment of myeloid cells into irradiated tumors thereby stimulating tumor recurrence. Results provide insights into molecular mechanisms regulating tumorigenic functions of myeloid cells in tumors re-growing after radiation therapy. Overall design: Samples were collected at day 4 from irradiated tumors in WT, TLR9KO and Stat3KO (MxCre/Stat3flox). There were total 11 samples with  3-4 replicates of each sample type.

Description
Elucidating the top of the mammary epithelial cell hierarchy is highly important for understanding its regeneration capabilities and identifying target cells for transformation. Aiming for enriched mammary epithelial stem cell population, CD200highCD200R1high epithelial cells were identified. These cells represent ~50% of the mammary repopulating units (MRUs, CD49fhigh CD24med ) and termed MRUCD200/CD200R1. Gene expression of these cells was compared to all other MRU cells, termed MRUnot CD200/CD200R1, as well as individual CD200+ population (MRU-CD200R1-) and CD200R1+ population (MRU-CD200-). Overall design: Gene expression from mammary epithelial cells carrying sorted by CD200, CD200R1 markers and MRU markers. Four populations were sequenced: MRU-positive CD200 positive and CD200R1 positive; MRU-positive and not CD200 positive CD200R1 positive; not MRU CD200 positive CD200R1 negative; not MRU CD200 negative CD200R1 positive. There are 5 replicates from 5 individual mice.

Description
Transcriptional profiling of the zebrafish embryonic host response to a systemic bacterial infection with Salmonella typhimurium (strain SL1027); comparison between traf6 knock-down and control morpholino treated embryos. Overall design: All infection experiments were performed using mixed egg clutches of ABxTL strain zebrafish. Embryos injected with traf6 morpholino or a 5bp mismatch control morpholino were staged at 27 hours post fertilization (hpf) by morphological criteria and approximately 250 cfu of DsRed expressing Salmonella bacteria were injected into the caudal vein close to the urogenital opening. As a control an equal volume of PBS was likewise injected. Pools of 20-40 infected and control embryos were collected 8 hours post infection (hpi). The whole procedure was preformed in triplicate on separate days. Total RNA of the biological triplicates was pooled using equal amounts of RNA prior to RNAseq library preparation.
