Project description:To profile miRNA expression variations across six adipose depots, a total of 36 adipose samples underwent high-throughput small RNA sequencing.
Project description:To characterize the transcriptome differences between different adipose depots, a total of 36 adipose samples were used for high-throughput sequencing. At last, about 23,000 transcripts were identified.
Project description:*Background: Adipocytes mainly function as energy storage and endocrine cells. The amount and distribution of fat are important factor that influence the meat quality in the beef industry. Fat depot can be found around internal organ (ometal), beneath the skin (subcutaneous), and between muscles (intramuscular). Different adipose depot showed the biological and genetic difference depending on their location. This inter-depot variation might be influenced by the inherent genetic programing for development of adipose depots. In this study, we used RNA-seq data to investigate the difference in transcriptome of various adipose depots in Hanwoo. *Results: Using RNA-seq, we identified 5797, 2156, and 5455 DEGs in the comparison between OI, OS, and IS respectively (FDR<0.01) and found 853, 48, and 979 DEGs specific to subcutaneous, intramuscular and omental fat respectively. DEGs in intramuscular fat were highly enriched the metabolism related pathways compared to other fat depots. DEGs specific to the omental fat is significantly enriched in PPAR signaling pathway and cell-junction related pathway. In subcutaneous fat, cytokine-cytokine receptor interaction with chemokines (CXC and CC subfamily) was the most significantly enriched the pathways. Interestingly, melanogenesis pathway was associated with the subcutaneous depot. Even though the adipose tissues shared the same pathways for adipocyte differentiation, the regulation of genes were different based on the depot. *Conclusions: We comparatively analyzed the transcripome profile from different adipose tissues using NGS and identified DEGs between adipose depot and specific to depot in Hanwoo animals. The functional annotation analysis of DEGs found that transcriptome profile difference in various adipose tissue of intramuscular, subcutaneous, and ometal fat.

Project description:Comparing gene expression profiles of murine subcutaneous vs. visceral adipose tissue. Gene expression was analyzed in two subcutaneous depots (inguinal and axillary) and two visceral depots (epididymal and mesenteric) from male C57Bl/6 mice.
Project description:Comparing gene expression profiles of murine subcutaneous vs. visceral adipose tissue. Gene expression was analyzed in two subcutaneous depots (inguinal and axillary) and two visceral depots (epididymal and mesenteric) from male C57Bl/6 mice. 4 samples were analyzed as two groups: inguinal and axillary (subcutaneous) and epididymal and mesenteric (visceral). Each sample was derived by pooling RNA from the relevant fat depot from 3 age-matched, male C57Bl6 mice.
Project description:We performed RNA sequencing on the sorted adipose stem cells (ASCs) from multiple white adipose tissue depots to analyze the differential expression and pathway enrichment analysis of adipose stem cells from different anatomical sites.
Project description:The two major mammalian adipose tissue depots are subcutaneous adipose tissue (SAT), which is associated with metabolic protection, and abdominal/visceral (VAT), which contributes to metabolic disease. To investigate the molecular underpinnings of these differences, we conducted a comprehensive analysis of the proteomes of adipocytes and whole tissue from these different depots across two different diets in male C57Bl/6J mice.
Project description:In the last decades, adipose tissue has been defined to play a central role in the control of energy balance. Furthermore, the proven endocrine and thermogenic functions of adipocytes have renewed interest in the study of this tissue, as the activation of non-shivering thermogenesis may hold great potential for the future treatment of obesity and T2D. Cold exposure has defined to activate this process. Here, the miRNA transcriptomic response of epididymal and inguinal white adipose depots (eWAT and iWAT, respectively) as well as that of the interscapular brown adipose depot (iBAT) of C57Bl/6 mice either exposed to 22ºC or 4ºC for the period of 4 days were examined. This in-detail study of the adaptation of each depot to cold exposure has allowed unraveling depot-specific regulatory molecular mechanisms.
