Illumina ratRef-12 v1.0 expression beadchip
Description
Hydroxyapatite-coated cellulose induces a quicker and stronger inflammatory response compared to uncoated cellulose. Furthermore, the coated cellulose increases the homing at circulating bone-marrow derived progenitor cells. For this reason, Illumina microarray was used to study the early gene expression of the forming granulation tissue in the hydroxyapatite-coated sponges.

Description
The prevalence of obesity has been increasing rapidly worldwide during the past two decades. This is alarming, since obesity has considerable effects on morbidity and mortality. The majority of gene expression studies about the effect of obesity and weight loss have been performed using the adipose tissue for mRNA extraction. However, also the liver plays a central role in maintaining energy balance. To our knowledge, no overall analysis of hepatic gene expression in response to changes in nutritional status has been made in humans Therefore, it is important to investigate how a short-time hypocaloric diet affects overall hepatic gene expression and the metabolic profile in a group of overweight and obese women. The subjects (n=31) were middle-aged, overweight (BMI>25 kg/m2) women with gallstone disease scheduled for an elective gallbladder operation. The intervention subjects were placed on a hypocaloric AHA step I diet with a recommended daily energy intake of 5.0 MJ. The objective was to reduce 0.5 kg of body weight per week. The control subjects were instructed to continue their habitual diet and not to lose weight. Basic clinical measurements and laboratory analyses were performed twice at baseline and at two week intervals during the weight reduction period. Surgical liver biopsies were obtained at the end of the weight reduction period. RNA samples of 4 individuals from the intervention group and 4 individuals from the control group were selected for the microarray analysis. The results from the microarray analysis were fairly surprising. Only one gene was up-regulated and the rest 142 down-regulated in the diet intervention group compared to the control group when a minimum of 2-fold change was set as the limit. The global decrease in hepatic gene expression was unexpected but the results are interesting, with several genes not previously linked to weight reduction. The decrease in triglyceride and fasting plasma insulin concentrations observed in our study is in accordance with results from many previous weight-loss trials.

Description
We performed micrarrays to investigate neuronal gene expression changes during acute inflammatory CNS axon injury using the murine myelin oligodendrocyte glycoprotein 35-55 (MOG35-55)-induced experimental autoimmune encephalomyelitis (EAE) model. The present study was assigned to assess the direct and indirect endogenous neuronal response to spinal axonal injury in the motor and sensory cortex.

Description
The production of definitive haematopoietic stem/progenitor cells from human pluripotent stem cells (hPSCs) remains a significant challenge. Using reporter lines to track the endothelial (SOX17) to haematopoietic (RUNX1C) transition, we found that hPSC differentiated in growth factor supplemented serum free medium generated RUNX1C+CD34+ clonogenic cells that homed to the bone marrow, but did not engraft. Compared to repopulation-competent cord blood CD34+ cells, RUNX1C+CD34+ progenitors lacked HOXA gene expression, indicating incorrect mesoderm patterning. This deficiency was ameliorated by a timed pulse of WNT activation combined with ACTIVIN antagonism. Significantly, these HOXA+ cultures now formed complex SOX17+ vessels that produced fetal liver-like haematopoietic cells, similar to the human aorta-gonad-mesonephros (AGM). Comparison of transcriptional profiles of these nascent haematopoietic stem/progenitors with cells isolated from human AGM confirmed significant similarities, consistent with the assignment of our in vitro generated cells to the definitive human haematopoietic lineage. Our findings argue that HOXA codes established early in differentiation predict cellular potential and provide correct cell patterning for the specification of definitive haematopoietic lineages from hPSCs. Overall design: mRNA profiles of 26 samples were obtained for 5 different cell populations and 2 different treatments.

Description
Heparan sulfate (HS), a long linear polysaccharide, is implicated in various steps of tumorigenesis, including angiogenesis. We successfully interfered with HS biosynthesis using a peracetylated 4-deoxy analog of the HS constituent GlcNAc and studied the compounds metabolic fate and its effect on angiogenesis. The 4-deoxy analog was activated intracellularly into UDP-4-deoxy-GlcNAc and HS expression was inhibited up to ~96% (IC50 = 16 M). HS chain size was reduced, without detectable incorporation of the 4-deoxy analog, likely due to reduced levels of UDP-GlcNAc and/or inhibition of glycosyltransferase activity. Comprehensive gene expression analysis revealed reduced expression of genes regulated by HS binding growth factors as FGF-2 and VEGF. Cellular binding and signaling of these angiogenic factors was inhibited. Micro-injection in zebrafish embryos strongly reduced HS biosynthesis, and angiogenesis was inhibited in both zebrafish and chicken model systems. All these data identify 4-deoxy-GlcNAc as a potent inhibitor of HS synthesis which hampers pro-angiogenic signaling and neo-vessel formation.
