Project description:To understand differences in microRNA (miRNA) signatures between two different diets with and without EPA in brown, subcutaneous, and viscerl tissue from C57BL/6 mice to understand mechanistic insight regarding their contribution to metabolic disorders in obesity. We performed small RNA-sequencing of brown, subcutaneous adipose from high fat diet (45% kcal from fat) and high fat diet 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). AS a total 1251 miRNAs were identified in three adipose tissue and out of which in bown adipose tissue 15 showd differential expression between BF-HF and BF-EPA .IN subcutaneous adipose tissue 3 miRNAs showed differntial expression between SUB-HF and SUB-EPA. EPA differentially regulate specific miRNAs expression in brown, subcutaneous, and visceral adipose tissue.

Project description:The prevalence of obesity and overweight is steadily rising, posing a significant global challenge for humanity. The fundamental cause of obesity and overweight lies in the abnormal accumulation of adipose tissue. While numerous regulatory factors related to fat deposition have been identified in previous studies, a considerable number of regulatory mechanisms remain unknown. tRNA-derived small RNAs (tsRNAs), a novel class of non-coding RNAs, have emerged as significant regulators in various biological processes. In this study, we obtained small RNA sequencing data from subcutaneous white adipose tissue and omental white adipose tissue of lean and obese pigs. In addition, we similarly obtained tsRNAs profiles from scapular brown adipose tissue (BAT), inguinal white adipose tissue (iWAT) and epigonadal white adipose tissue (eWAT) of normal mice. Finally, we successfully identified a large number of expressed tsRNAs in each tissue type and identified tsRNAs conserved in different adipose tissues of pigs and mice. These datasets will be a valuable resource for elucidating the epigenetic mechanisms of fat deposition.

Project description:Brown adipose tissue is a specialized fat tissue involved in heat generation by using a process termed thermogenesis. This ability to convert nutrient energy into heat sets brown adipocytes apart from the more common type of white adipocytes, which are mainly involved in energy storage. Brown adipose depots occur as a large interscapular depot in mice. Brown adipocytes are multilocular, i.e. contain many small lipid-filled vacuoles and uniquely express the uncoupling protein 1. In this study, the gene expression patterns in brown adipose tissue samples of young, healthy mice was analyzed.

Project description:This project aims to identify the proteins present in RNA granules of brown adipose tissue upon exposure to cold challenge. Wild type C57BL/6J mice were born and raised at thermoneutrality and were then subjected to cold exposure for 90 minutes. Brown adipose tissues were collected, and the protein lysates of RNA granules isolated from the brown adipose tissues were separated using SDS-PAGE gels and visualized with Coomassie stain. The protein bands were subsequently excised for downstream sample processing.

Project description:Next generation sequencing was used to compare transcriptome profiling in brown adipose tissue from Ctrl and BKO mice with mature brown adipose tissue specific deletion of BSCL2. Using an optimized data analysis workflow, we identified 13,525 transcripts in brown adipose tissue. 243 genes were differentially expressed with a fold change ≥1.5 and Padj value <0.05. Only 99 genes showed differential expression between the Ctrl and BKO brown fat, with a fold change ≥2.0 and Padj value <0.05. Results provide insights into the processes and signaling pathways BSCL2-mediated in brown adipose tissue.

Project description:We performed a genome-wide deep sequencing analysis of the microRNAs abundant in mesenchymal stem cells (MSCs) derived from murine brown adipose tissue and in in vitro differentiated mature brown adipocytes. Several microRNAs were identified as differentially regulated when comparing datasets from MSCs vs. mature fat cells. These microRNAs may have an implication in the regulation of adipogenesis as well as thermogenesis in brown adipose tissue (BAT).
