Effect of maple syrup extract on the liver of mice fed a high-fat diet

Project description:The effects of the administration of maple syrup extract (MSX) on hepatic gene expression were investigated in mice fed high-fat diet. Male C57BL/6J mice aged 3 weeks were purchased from Charles River Japan (Kanagawa, Japan) and housed in a room maintained at 23 ± 1°C and 49 ± 16% humidity with a 12-h light/dark cycle (light 08:00–20:00; dark 20:00–08:00). For 1 week acclimation period after purchase, all the mice were fed a low-fat diet (10 kcal% fat). Then, they were randomly divided into three different dietary groups: the first group with the food containing fat at 10 kcal% as low-fat diet, the second group with 45 kcal% as high-fat diet, and the third with HFD plus 0.06% MSX. The mice were fed ad libitum for 8 weeks.

MicroRNAs Expressed in Visceral Adipose Tissue from Mice Fed High-Fat Diets Supplemented with Eicosapentaenoic Acid (EPA)

Project description:The goal of this subproject is to identify microRNAs (miRNAs) expressed in visceral (VIS) adipose tissue (gonadal fat from male C57BL/6 mice) and regulated by eicosapentaenoic acid (EPA). This will provide insight into microRNAs regulated by EPA and their potential role in obesity-associated inflammation. We performed small RNA-sequencing of white (VIS) adipose tissue from high-fat diet (45% kcal from fat) supplemented with EPA (45% Kcal from fat, 6.75% EPA). Using the Gunaratne Next-Generation pipeline (published in Creighton et al. 2009), miRNA expression profiles were identified. Counts of each unique read were normalized to total usable reads, and had 40 counts added. We mapped about 13.8 million sequence reads per sample to the Mus musculus genome (build mm 10). We are specifically interested in those miRNAs expressed in VIS fat from EPA-fed mice compared to HF-fed mice.

Differential expression of genes in pancreatic islet of C57Bl/6J on high fat diet

Project description:Male C57Bl/6J mice were fed 45%kcal fat diet (HF) or regular rodent chow (NC) from 4 weeks to 16 weeks of age. Gene expression was compared between RNA obtained from pancreatic islets of HF fed mice and NC mice.

Adipose depot differences in high fat fed mice

Project description:Purpose : To understand differences in microRNA (miRNA) signatures of different adipose tissue depots to gain mechanistic insight regarding their contribution to metabolic disorders in obesity. Method : We performed small RNA-sequencing of brown, subcutaneous and visceral adipose depots from high fat diet-fed mice (mice were fed a 45% kcal fat diets from 5-6 weeks of age for 11 weeks). The main animal study reference: Kalupahana et al., J. Nutr, 2010 Results:Using the Gunaratne Next Generation pipeline (published in Creighton et al. 2009) miRNA expression profiles were identified. Counts of each unique read were normalized to total usable reads, and had 40 counts added. We mapped about 13.8 million sequence reads per sample to the Mus musculus genome (build mm 10). Altogether 1251 miRNAs were identified in three adipose tissues and out of which 246 showed differential expression with 1.25 or more fold change and p value <0.05 in one or more of the pairwise comparisons of the 3 adipose depots. Hierarchical clustering, demonstrated that biological replicates behaved appropriately as they were clustered together. BAT exhibited a different gene/ miRNA expression pattern than the 2 other WATs (SAT and VAT). SAT and VAT showed a closer relationship with each other than with BAT Conclusion : High fat diet differentially regulate specific miRNAs expression in different adipose tissue depots

Identification of Fra-1 and/or Fra-2 regulated genes in MDA-MB231 cells

Project description:In the paper "Fra-1 regulates its target genes via binding to remote enhancers without exerting major control on chromatin architecture in triple negative breast cancers" by Bejjani et al., we identified Fra-1 and/or Fra-2 target genes in MDA-MB-231 cells. si RNA against Fra-1 and against Fra-2 were transfected in MDA-MB-231 cells either independenlty or simultaneously to identify genes regulated specifically by Fra-1 or Fra-2 and genes regulated redundantly or complementarily by Fra-1 and Fra-2 total RNA were purified and biotinylated sense-strand cDNA were produced. cDNA targets were used to probe Affymetrix GeneChip Human Gene 2.0 ST arrays

Comparative analysis of gene expression in Fra-1+/+ and Fra-1-/- mice lung

Project description:We hypothesized that gene expression in lungs of Fra-1+/+ and Fra-1-/- mice are divergent thus contributing fibrosis. More specifically, Fra-1-/- mice are increased susceptible to fibrosis. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between Fra-1+/+ and Fra-1-/- mice at early time point. This study utilizes microarray analysis to test these hypotheses. 5 days PBS and bleomycin treated lung samples from both Fra-1+/+ and Fra-1-/- mice were used. RNA was isolated and used for global gene expression profiling (Affymetrix MoGene 1.0ST v1 Array). The raw probe signal intensities were quantile normalized over all samples, summarized with the robust multi-array average (RMA) algorithm and log2 transformed with a median polish, using the Affymetrix Power Tools. We considered a transcript cluster (gene-level) to be reliably expressed in a sample if the Affymetrix implemented DABG (detection above ground) p-value was less than 0.05. We used local-pooled-error (LPE) estimates and robust statistical tests for evaluating significance of each gene's differential expression in a comparison.

Transcript profiling in peritoneal macrophages from wildtype, Fra-1ΔMxCre or Fra-2ΔLysMCre mice

Project description:The polarization and activation of macrophages are controlled synergistically by transcription factors such as NF-κB and AP-1 transcription factor members. Surprisingly, little is known about the role of the Fra proteins, both members of the AP-1 transcription factor family, in macrophage activity. To determine the full profile of Fra network, microarray RNA expression analysis using Agilent Technologies platform was performed in wild-type, Fra-1ΔMxCre or Fra-2ΔLysMCre macrophages.
