Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Acute Lymphoblastic Leukemia (ALL) in infants (<1 year of age) is characterized by a high incidence of MLL translocations which is associated with a poor prognosis. Contributing to this poor prognosis is cellular drug resistance, especially to glucocorticoids like prednisolone. Although in vitro prednisolone resistance mechanisms have been proposed in pediatric ALL, it has never been studied in MLL-rearranged infant ALL, which are highly resistant to glucocorticoids in vitro and in vivo.

Description
Eicosapentaenoic acid in its free fatty acid form (EPA-FFA), 2g daily, is safe and well-tolerated in patients undergoing liver resection surgery for colorectal liver metastasis.Oral EPA incorporates into colorectal liver metastasis tissue. EPA-FFA treatment is associated with reduced vascularity of liver metastases in -3 PUFA-nave patients. Preoperative (median 30 days) EPA-FFA treatment may have prolonged benefit on postoperative overall and disease-free survival.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
The pathophysiology of endometriotic lesion development remains unclear but involves a complex interaction between ectopic endometrium and host peritoneal tissues. We hypothesised that disruption of this interaction was likely to suppress endometriotic lesion formation. We hoped to delineate the molecular and cellular dialogue between ectopic human endometrium and peritoneal tissues in nude mice, as a first step towards testing this hypothesis. Human endometrium was xenografted into nude mice and the resulting lesions were analysed using microarrays. A novel technique was developed that unambiguously determined whether RNA transcripts identified by the microarray analyses originated from human cells (endometrium) or mouse cells (stroma). Four key pathways (ubiquitin/proteosome, inflammation, tissue remodelling/repair and ras-mediated oncogenesis) were revealed, that demonstrated communication between host stromal cells and ectopic endometrium.

Description
Despite the prevalence and recognition of its detrimental impact, clinical complications of sepsis remain a major challenge. Here, we investigated the effects of myeloid ferritin heavy chain (FtH) in regulating the pathogenic sequelae of sepsis. We demonstrate that deletion of myeloid FtH leads to tolerance towards sepsis as evidenced by reduced serum cytokine levels, multi-organ dysfunction and subsequent mortality. We identified that such tolerance is predominantly mediated by the compensatory increase in circulating ferritin (ferritin light chain; FtL) in the absence of myeloid FtH. Our in vitro and in vivo studies indicate that prior exposure to ferritin provides significant tolerance to the septic process by restraining an otherwise dysregulated response to infection. These findings are mediated by an inhibitory action of ferritin on NF-?B activation and its downstream effects. Taken together, our findings suggest an essential immunomodulatory function for circulating ferritin and enhances our understanding of this acute phase reactant. Overall design: Total RNA were isolated from blood leukocytes of wild type FtH mice and Myeloid deficient FtH mice following sham and CLP surgery. Three biological replicates were considered for each genotype and surgery type.

Description
Diurnal temperature cycling is an intrinsic characteristic of many exposed microbial ecosystems. However, its influence on yeast physiology and transcriptome has not been studied in detail. In this study, 24-h sinoidal temperature cycles, oscillating between 12 and 30C, were imposed on anaerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae. After three diurnal temperature cycles (DTC), concentrations of glucose, and extracellular metabolites, as well as CO2-production rates showed regular, reproducible circadian rhytms. DTC also led to waves of transcriptional activation and repression, which involved one sixth of the yeast genome. A substantial fraction of these DTC-responsive genes appeared to primarily respond to changes in glucose concentration. Elimination of known glucose-responsive genes revealed overrepresentation of previously identified temperature-responsive genes as well as genes involved in cell cycle and de novo purine biosynthesis. Analyses of budding index and flow cytomery demonstrated that DTC led to a partial synchronization of the cell cycle of the yeast populations in the chemostat cultures, which was lost upon release from DTC. Comparison of DTC results with data from steady-state cultures showed that DTC was sufficiently slow to allow S. cerevisiae chemostat cultures to almost completely acclimatize their transcriptome and physiology at the DTC temperature maximum, and to approach acclimation at the DTC temperature minimum.
