Description
Purpose: We investigated the tetrachloroethylene associated changes in kidney transcriptomes among healthy mice, nonalcoholic fatty liver disease mice, and nonalcoholic steatohepatitis mice. Overall design: Male C57BL/6J mice were fed a low-fat diet (4% fat), high-fat diet (31% fat), or methionine/choline/folate deficient diet. Following an 8-week diet, mice were administered either a single dose of tetrachloroethylene (PERC, 300 mg/kg/d in 5% Alkamuls-EL620 in saline, 5 mL/kg) and euthanized at 24 hours post dose, or five consecutive daily doses of PERC or vehicle (n=8/diet/treatment) and euthanized at 4hours post dose. The harvested kidneys were subjected to mRNA sequencing using Illumina Hiseq 2500. Jac-NASH-063 was excluded from analysis because it did not have a good yield.

Description
We report the effect of NAFLD on liver gene expression changes that could impact tetrachloroethhylene metabolism Methods: We fed male C57Bl/6J mice a base diet (BD), high fat (HFD), or methionine/choline/folate deficient high fat diet (MCD) for 8 weeks and then treated them with vehicle or tetrachloroethylene (PERC, 300 mg/kg ig). We only report "basal" differences herein (aka vehicle-treated). Results: We report that there were diet-specific differences in xenobiotic metabolizing genes, and that these genes may be responsible for NAFLD-induced disruption in PERC metabolism Overall design: Examination of liver left lobe gene expression for 3 different diets fed to C57Bl/6J male mice

Description
Low-oxygen stress associated with natural phenomena such as waterlogging, results in widespread transcriptome changes and a metabolic switch from aerobic respiration to anaerobic fermentation. High-throughput sequencing of small RNA libraries obtained from low-oxygen stressed and control root tissue identified a total of 65 unique microRNA (miRNA) sequences from 46 families, and 14 trans-acting small interfering RNA (tasiRNA) from 3 families. Low-oxygen stress resulted in changes to the abundance of 46 miRNAs from 19 families, and all 3 tasiRNA families. Chemical inhibition of mitochondrial respiration caused similar changes in expression in a majority of the low-oxygen responsive small RNAs analysed. Our data indicate that miRNAs and tasiRNAs play a role in gene regulation and possibly developmental responses to low oxygen, and that a major signal for these responses is likely to be dependent on mitochondrial function. Keywords: Small RNA transcriptome analysis Overall design: Examination of root tissue under 2 different environments, control and low oxygen

Description
4 week old Arabidopsis plants, of ecotype Columbia, SALK_084897 or SAIL_303_D08 were either grown under normal conditions or grown under normal conditions for before having a moderate light and drought treatment applied. Light and drought treatment was applied by withholding water for 5 days prior to transfer to 300 uE m-2 s-1 light conditions. Samples were collected after 3 days of treatment or for the same age plants grown under normal conditions.

Description
In almost every countries the proportion of people over 60 years is growing faster that any other age group. Increased life expectancy is leading to the characterization of specific aspects of aging for the various physiological systems. The study of healthy aging is important to design strategies capable to maximize the health and to prevent chronic diseases in older people. Immunosenscence reflects the age-related changes of the immune system and the reduced capacity of elderly people to cope with new infections. To elucidate changes in gene expression related to systemic aging and immunosenescence in an unbiased manner we performed comparative microarray analysis on whole blood cell from healthy middle-aged versus elderly men, and correlated results with functional measurements of aerobic capacity. Blood cells from elderly subjects showed age-related changes in the expression of several markers of immunosenescence, inflammation and oxidative stress, and showed impairments in metabolic and biosynthetic capacities.

Description
Arabidopsis ATH1 Genome Arrays were used to analyse changes in transcript abundance between Col-0 (wild-type) Arabidopsis seedlings and either single T-DNA insertional KO mutants of LETM1 (At3g59820)(T-DNA lines; SALK_067558C (letm1-1) and SALK_058471 (letm1-2)) or LETM2 (At1g65540) (T-DNA line; SALK_068877 (letm2-1)). Additionally, letm1 and letm2 knock out Arabidopsis lines were crossed to generate double mutants, however a double knock-out of these two genes results in an embryo lethal phenotype. Hemizygous plants were generated that were homozygous knock out for LETM1 and heterozygous knock out for LETM2, and visa versa, termed (letm1(-/-)LETM2(+/-) and (LETM1(+/-)letm2(-/-) respectively. Note that (letm1(-/-)LETM2(+/-) displays a mild developmental defective phenotype in the first 10-14 days of growth, while (LETM1(+/-)letm2(-/-) shows no phenotype. Microarray analysis was carried out on all three single homozygous knock out lines, and also on both combinations of the hemizygous mutation between the two genes, and compared with a wild-type Col-0 control to gain insight into global transcript abundance changes in these mutant lines. Arrays were performed in triplicate for each genotype, from RNA isolated from 3 independent pools of 5-10 Arabidopsis seedlings at 10 days old.
