microRNAs array of livers from three different lifestyle modification mice models

Project description:To investigate the microRNAs involved in the processes of beneficial and detrimental lifestyles, including caloric restriction(CR), exercise and high-fat diet(HF), we performed a comprehensive and thorough comparison of microRNAs expression profiles in liver among these lifestyle modifications.

Imporatance of substantial weight loss for altering gene expression during intensive cardiovascular lifestyle modification

Project description:The objective of this study was to examine relationships between weight loss through changes in lifestyle and peripheral blood gene expression profiles. Substantial weight loss (-15.2+3.8%) in lifestyle participants was associated with improvement in selected cardiovascular risk factors and significant changes in peripheral blood gene expression from pre- to post-intervention: 132 unique genes showed significant expression changes related to immune function and inflammatory responses involving endothelial activation. In contrast, participants losing minimal weight (-3.1+2.5%) showed only minor changes in cardiovascular risk factors and markers of inflammation, and no changes in gene expression compared to non-intervention controls after 1 year. Weight loss (>10%) during lifestyle modification is associated with down-regulation of genetic pathways governing interactions between circulating immune cells and the vascular endothelium and may be required to successfully reduce CVD risk. A prospective nonrandomized trail was conducted over 1 year in participants undergoing intensive lifestyle modification to reverse or stabilize progression of coronary artery disease. Cardiovascular risk factors, inflammatory biomarkers, and gene expression as a function of weight loss were assessed in 89 lifestyle participants and 71 retrospectively matched controls undergoing usual care.

Differential microRNAs expression profiles in liver from three different lifestyle modification mice models.

Project description:BackgroundMicroRNAs play an important role in many fundamental biological and pathological processes. Defining the microRNAs profile underlying the processes by beneficial and detrimental lifestyles, including caloric restriction (CR), exercise and high-fat diet (HF), is necessary for understanding both normal physiology and the pathogenesis of metabolic disease. We used the microarray to detect microRNAs expression in livers from CR, EX and HF mice models. After predicted potential target genes of differentially expressed microRNAs with four algorithms, we applied GO and KEGG to analyze the function of predicted microRNA targets.ResultsWe describe the overall microRNAs expression pattern, and identified 84 differentially expressed microRNAs changed by one or two or even all the three lifestyle modifications. The common and different enriched categories of gene function and main biochemical and signal transduction pathways were presented.ConclusionsWe provided for the first time a comprehensive and thorough comparison of microRNAs expression profiles in liver among these lifestyle modifications. With this knowledge, our findings provide us with an overall vision of microRNAs in the molecular impact of lifestyle on health as well as useful clues for future and thorough research of the role of microRNAs.

RNA-seq of three groups mice in livers.

Project description:We sought to examine whether urolithin A could alleviate the alcohol-related liver disease. RNA-sequencing (RNA-seq) on mice livers were performed in order to identify the key biological processes and pathways regulated by urolithin A.

Gene expression profile of overgrown livers from genetic models involving YAP or MYC overexpression.

Project description:We reasoned that when livers grow beyond their normal size, some growth regulating secreted factors will be suppressed and others will be overexpressed. To obtain overgrown livers, we used genetic models involving YAP or MYC overexpression We the identified differentially expressed genes in both models and filtered out secreted factors by bioinformatically defined secreted protein list.
