- Affymetrix Rat Genome U34 Array (rgu34a)
Description
Analysis of the gene signature of steatosis associated to obesity in hepatocytes of Zucker fa/fa obese rats and their controls; identifying target genes linked to steatosis progression. or Obesity and insulin resistance-associated steatosis can be a non-inflammatory condition affecting hepatocytes or progress to steatohepatitis: a condition that can result in end-stage liver disease. Although molecular events leading to accumulation of lipid droplets in the liver have been identified individually, the complexity of the condition suggested that emergent target would be uncovered by a more comprehensive examination. Then, this study was aimed at establishing a gene signature of steatosis in hepatocytes and at identifying target genes linked to steatosis progression. Using Affymetrix oligonucleotide arrays, we compared transcriptomes of hepatocytes isolated from Zucker "fa/fa" obese rats with three different age-related grades of steatosis with those of their counterpart non-steatotic cells.

Description
Two of the most prevalent ovarian diseases affecting women's fertility and health are Primary Ovarian Insufficiency (POI) and Polycystic Ovarian Syndrome (PCOS). Previous studies have shown that exposure to a number of environmental toxicants can promote the epigenetic transgenerational inheritance of ovarian disease, including decreases in the primordial follicle pool of oocytes that are similar to what is seen in POI, and increases in ovarian cysts that are similar to what is seen in PCOS. In the current study, transgenerational changes to the transcriptome and epigenome of ovarian granulosa cells are characterized in F3 generation rats after ancestral vinclozolin or DDT exposures compared to controls. There was an increase in ovarian disease in transgenerational F3 generation vinclozolin and DDT lineage rats at one year of age compared to F3 generation controls. In purified granulosa cells from 20 day old F3 generation females 164 differentially methylated regions (DMRs) (p<1e-06) were found in the F3 generation vinclozolin lineage, and 293 DMRs (p<1e-06) in the DDT lineage, compared to controls. The long non-coding RNAs (lncRNAs) and small non-coding RNAs (sncRNAs) were found to be differentially expressed in both the vinclozolin and DDT lineages with the sncRNAs having 492 sncRNAs (p<1 x 10-4) in the vinclozolin lineage and 1,085 sncRNAs (p<1 x 10-4) in the DDT lineage. The lncRNAs were differentially expressed with 123 and 51 in the vinclozolin and DDT lineages, respectively (p<1 x 10-4). Differentially expressed mRNAs were found in the vinclozolin lineage at 174 mRNAs (p<1 x 10-4) and the DDT lineage at 212 mRNAs (p<1 x 10-4). These transgenerational epigenetic changes contribute to the dysregulation of the ovary and disease susceptibility that can occur in later life. This suggests that ancestral exposure to toxicants is potentially a major risk factor that must be considered in the molecular etiology of ovarian disease.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
To identify proteins regulated by glucose through changes in their rate of protein synthesis, translational profiling of MIN6 cells acutely incubated at either low or high glucose concentration was performed (i.e. microarray analysis was performed on mRNAs associated with polysomes, as an increase in the association of mRNA with polysomes is indicative of an increase in the rate of initiation step of translation and hence an increase in protein expression) (Johannes et al., 1999; Mikulits et al., 2000).

Description
Bilirubin is a potent antioxidant that reduces inflammation and the accumulation of fat. There have been reports of gene responses to bilirubin, which was mostly attributed to its antioxidant function. These RNA-sequencing studies investigated the impact biliverdin, which is rapidly reduced to bilirubin, has on transcriptome responses in human HepG2 hepatocytes in a PPARa-dependent fashion. This investigation reveals that transcriptome responses from the generation of bilirubin are mostly PPARa-dependent, and its antioxidant function regulates a smaller set of genes.

Description
Sympathetic hyperactivity can result from cell-autonomous changes in neurons that innervate cardiovascular target tissues. Stellate ganglia are of particular interest because the majority of sympathetic neurons innervating the heart reside there. The cardiovascular risk profiles in men and women are different. Transcriptomics provides a powerful tool for identifying genomic changes that contribute to sympathetic dysfunction in disease. Here we compared the transcriptomes of healthy stellate ganglia from adult male and female WKY rats.

Description
The aim of this study was to analyze potential brown planthopper (BPH) resistant genes in Rathu Heenati (RHT) by Affymetrix whole rice genome array,BPH susceptible and resistant rice varieties of TN1Taichung Native 1as control. All the resistant related genes derived from RHT will be analyzed according to the SSR markers interval flanked on the chromosome 3, 4, 6 and 10. It will be benefit to the gene clone and marker assistant breeding for Bph3 gene in the near future.

Description
Overconsumption of high-fat diet (HFD) and sugar-sweetened beverages are risk factors for development of obesity, insulin resistance and fatty liver disease. To dissect mechanisms underlying this association, mice were fed chow or HFD with or without addition of fructose- or glucose-supplemented water. There were no physiological differences in mice supplemented with fructose or glucose on chow diet. Despite similar caloric intake, mice on HFD supplemented with fructose developed more pronounced obesity, glucose intolerance and hepatomegaly than glucose-supplemented mice. While both sugars increased Chrebp-?, fructose supplementation uniquely increased Srebp1c and downstream fatty acid synthesis genes resulting in reduced liver insulin signaling, whereas glucose enhanced total Chrebp expression and triglyceride synthesis but was associated with improved hepatic insulin signaling. Metabolomic and RNA sequence analysis confirmed dichotomous effects of fructose and glucose supplementation on liver metabolism in spite of inducing similar amount of hepatic lipid accumulation. Ketohexokinase, the first enzyme of fructose metabolism, was increased in fructose-fed mice and in obese adolescents with steatohepatitis. Knockdown of ketohexokinase-C in liver improved hepatic steatosis and glucose tolerance in fructose-supplemented mice. Thus, fructose is a component of dietary sugar that is uniquely associated with poor metabolic outcomes, while increased glucose intake may be protective.
