Project description:Transcript profiling of OB from control and odor stimulated mice to determine the effect of odor enrichment

Project description:We show that infant trauma, as modeled by infant paired odor-shock conditioning, results in later life depressive-like behavior that can be modulated by learned infant cues (i.e., odor previously paired with shock). We have previously shown that this infant attachment odor learning paradigm results in the creation of a new artificial maternal odor that is able to control pup behavior and retain its value throughout development. Here, we assess the mechanism by which this artificial maternal odor is able to rescue depressive-like behavior and show that this anti-depressant like effect results in glucocorticoid and serotonin (5-HT) related changes in amygdala gene expression and is dependent on amygdala 5-HT. Furthermore, increasing amygdala 5-HT and blocking corticosterone (CORT) in the absence of odor mimics the adult rescue effects elicited by the artificial maternal odor, suggesting a mechanism by which odor presentation exerts its repair effects. There are three experimental groups: 1: pups with no infant shock and the adult forced swim test (FST)with no odor; 2. pups with infant odor-shock pairing and the adult forced swim test (FST) with no odor; 3. pups with infant odor-shock pairing and adult forced swim test with infant odor.

Project description:To investigate the effect of different levels of compost treatment on root gene expression of Atriplex lentiformis, we set up a greenhouse experiment with three treatments of 10% (TC10), 15 (TC15), and 20% (TC20) compost amended, metalliferrous mine tailings. Plants were harvested at ~11 weeks and root samples were flash frozen in liquid nitrogen for RNA-seq analysis. We then performed gene expression profiling analysis using data obtained from RNA-seq of 9 root samples from 3 different treatments.

Project description:Oral administration of an extract of compost fermented with thermophiles to pigs reduces the incidence of stillbirth and promotes piglet growth. However, the mechanism by which compost extract modulates the physiological conditions of the animals remains largely unknown. Here, we investigate the effects of compost extract on the gene expression in the intestine of the rat as a mammalian model. Gene expression analyses of the intestine indicated that several immune-related genes were upregulated following compost exposure. Thus, thermophile-fermented compost can contain microbes and/or substances that activate the gut mucosal immune response in the rat.

Project description:aerobic compost microorganisms Raw sequence reads

Project description:Composts are the products obtained after the aerobic degradation of different types of organic matter wastes and can be used as substrates or substrate/soil amendments. There are a small but increasing number of reports that suggest that foliar diseases may be reduced when using compost as growing medium compared to standard substrates. The purpose of this study was to unravel the gene expression alteration produced by the compost to gain knowledge about the mechanisms involved in the compost-induced systemic resistance. A compost from olive marc and olive tree leaves was able to induce resistance against Botrytis cinerea in Arabidopsis compared to the standard substrate perlite. Microarray analyses revealed that 178 genes were differently expressed with a fold change cut off of 1 from which 155 were upregulated and 23 were down regulated in compost-grown compared to perlite-grown plants. Functional enrichment study of up regulated genes revealed that 38 Gene Ontology terms were significantly enriched. Response to stress, biotic stimulus, other organism, bacterium, fungus, chemical and abiotic stimulus, SA and ABA stimulus, oxidative stress, water, temperature and cold were significantly enriched terms as well as immune and defense responses, systemic acquired resistance, secondary metabolic process and oxireductase activity. Interestingly, PR1 expression, which was equally enhanced by growing the plants in compost and by B. cinerea inoculation, was further boosted in compost-grown pathogen-inoculated plants. Compost triggered a plant response that shares similarities with both systemic acquired resistance and ABA dependent/independent abiotic stress responses.
