Project description:Transcriptional profiling of mouse liver comparing control, scrambled-oligonucleotides (Cont)-treated mice with Perilipin 2-antisense oligonucleotides (Plin2-ASO)-treated mice. C57BL/6 mice on a high-fat diet were treated with oligonucleotides in vivo. The goal was to determine the effects of Plin2 down-regulation in the liver on global gene expression. Two-condition experiment, control oligonucleotides vs. Plin2-antisense oligonucleotides. Biological replicates: 4 control replicates, 4 Plin2-ASO replicates.

Project description:To investigate the differences in microRNA expression profiles between fibrotic and normal livers, we performed microRNA microarrays for total RNA extracts isolated from mouse livers treated with carbontetrachloride (CCl4) or corn-oil for 10 weeks (n=3/group). MicroRNAs were considered to have significant differences in expression level when the expression difference showed more than two-fold change between the experimental and control groups at p<0.05. We found that 12 miRNAs were differentially expressed in CCl4-induced fibrotic liver.
Project description:We identified genes expressed in mouse liver that are regulated by Cux2, a highly female-specific liver transcription factor whose expression is regulated by sex-dependent plasma GH patterns. Using siRNA to knockdown Cux2 expression in female liver, we show that female specific genes are predominantly repressed by Cux2 knockdown. In contrast, similar numbers of male-biased genes are repressed as are induced by Cux2 knockdown. A scrambled, non-specific siRNA was used as a control. (Published in Molec Cell Biology, TL Conforto et al, 2012) Liver RNA isolated from the following 3 groups of mice was used in the present study: (1) 8 wk old female mice treated with non-specific siRNA control (n = 13; 6 or 7 per each pool); (2) 8 wk old female mice treated with Cux2 siRNA and euthanized 5 days later (n = 5; 2 or 3 per each pool); (3) 8 wk old female mice treated with Cux2 siRNA and euthanized 8 days later (n = 4; 2 per each pool). These RNA pools were used in two separate sets of competitive hybridization experiments: 1) 8 wk non-specific siRNA treated vs. 8 wk Cux2 siRNA treated for 5 days; 2) 8 wk non-specific siRNA treated vs. 8 wk Cux2 siRNA treated for 8 days. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) RNA samples to Agilent Mouse Gene Expression 4x44k v1 microarrays (Agilent Technology, Palo Alto, CA; catalog # G4122F-014868) were carried out, with dye swapping for each of the two hybridization experiments to eliminate dye bias. Two microarrays, one for each mixed cDNA sample, were hybridized for each of the two fluorescent reverse pairs, giving a total of 4 microarrays.
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
Project description:The impact of high fat diet on secreted milk small RNA transcriptome was studied by isolating total RNA from milk fat fraction collected on lactation day 10 from control diet fed (C; n=5; 10% fat; 7% sucrose; Research Diets #D12450J, Brunswick, NJ) and high fat diet fed (HF; n=4; Research Diets #D12492, 60% of total kcal energy is fat and match 7% of total kcal is sucrose; Brunswick, NJ) mice.
