Project description:We employed a paradigm of chronic moderate alcohol intake from adolescence-to-adulthood in mice, and analyzed the alcohol effect on both behavioral and hypothalamic gene expression changes. We employed a paradigm of chronic moderate alcohol intake from adolescence-to-adulthood in mice. Before chronic alcohol drinking began, mice (3 weeks old) were allowed to adapt to drinking tubes with both tubes containing water from experimental day 1-5. After adaptation period, mice were randomly aside to 5% alcohol group, 10% alcohol group or water-only control group (n=16-18). Chronic alcohol drinking lasted to day 57 of the experiment without any change and interruption. Then each mouse is sacrificed by decapitation, and the hypothalamus was dissected for rapid freeze and storage at -80 M-BM-:C. Hypothalamus tissue samples were used for total RNA extraction. RNA samples were pooled for microarray. For water-only group, nine mice were used to make three pools, with three equal amounts of RNA samples per pool. For alcohol group, nineteen mice were used to make nine pools, with one to three equal RNA samples per pool.

Project description:We investigated the molecular mechanisms of chronic alcohol consumption or lipopolysaccharide insult by gene expression profiling in prefrontal cortex and liver of C57BL/6J mice. We identified similar patterns of transcriptional changes in brain and liver among three different alcohol consumption tests and lipopolysaccharide injection. We also demonstrated distinct genomic consequences of different types of alcohol consumption. The microarray experiment was performed to compare gene expression changes induced by three separate paradigms of alcohol consumption and immune activation by lipopolysaccharide injection. The three tests of alcohol consumption were the continuous chronic two bottle choice (Chronic), two bottle choice available every other day (Chronic Intermittent) and limited access to one bottle of ethanol (Drinking in the Dark). All alcohol studies utilized 20% ethanol and each treatment group had it's own control group which received only water. The immune activation test consisted of 2 lipopolysaccharide injections (1 mg/kg i.p.) spaced one week apart, with animals being sacrificed one week after the last injection. Control animals received saline injections. All studies used female, adult mice.

Project description:Chronic stress exposure in adolescence can lead to a lasting change in stress responsiveness later in life and is associated with increased mental health issues in adulthood. Here we investigate whether the Chronic Social Instability (CSI) paradigm in mice influences the molecular response to novel acute stressors
Project description:The aim of this study was to assess whether chronic treatment with RPV can modulate the progression of chronic liver disease, especially of non-alcoholic fatty liver disease (NAFLD), through a nutritional model in wild-type mice Mice were daily treated with RPV (p.o.) and fed with normal or high fat diet during 3 months to induce fatty liver disease
