Project description:We asked if miRNAs are involved in PRDM16 protein expression. Thus microarray was employed with inguinal adipose tissues from contol, fasted and cold exposure C57BL/6J male mice In this dataset, we include all the miRNA expression data obtained from dissected mouse inguinal adipose tissues from control, fasted and cold exposure mice.

Thus microarray was employed with inguinal adipose tissues from contol, fasted and cold exposure C57BL/6J male mice In this dataset, we include all the miRNA expression data obtained from dissected mouse inguinal adipose tissues from control, fasted and cold exposure mice. Generally, microRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. Based on previous results, we asked whether miRNAs are involved in the regulation of PRDM16 in ingWAT in response to different physiological stimuli. We therefore performed miRNA microarray analysis using ingWAT from the cold-exposed mice, the fasted mice and the control mice. Given that cold exposure increased the level of PRDM16 protein whereas fasting decreased its expression, miRNAs that have expression patterns opposite to that of PRDM16 were selectedã??
Project description:We sequenced 14 mouse tissues' small RNA samples from C57BL/6J mouse and aligned the sequenced reads to miRBase_v16 to profile miRNA expression levels in these 14 tissues.

Project description:FGF21 is a novel secreted protein with robust anti-diabetic, anti-obesity, and anti-atherogenic activities in preclinical species. In the current study, we investigated the signal transduction pathways downstream of FGF21 following acute administration of the growth factor to mice. Focusing on adipose tissues, we identified FGF21-mediated downstream signaling events and target engagement biomarkers. Specifically, RNA profiling of adipose tissues and phosphoproteomic profiling of adipocytes, following FGF21 treatment revealed several specific changes in gene expression and post-translational modifications, specifically phosphorylation, in several relevant proteins. Affymetrix microarray analysis of white adipose tissues isolated from both C57BL/6 (fed either regular chow or HFD) and db/db mice identified over 150 robust potential RNA transcripts and over 50 potential secreted proteins that were changed greater than 1.5 fold by FGF21 acutely. Phosphoprofiling analysis identified over 130 phosphoproteins that were modulated greater than 1.5 fold by FGF21 in 3T3-L1 adipocytes. Bioinformatic analysis of the combined gene and phosphoprotein profiling data identified a number of known metabolic pathways such as glucose uptake, insulin receptor signaling, Erk/Mapk signaling cascades, and lipid metabolism. Moreover, a number of novel events with hitherto unknown links to FGF21 signaling were observed at both the transcription and protein phosphorylation levels following treatment. We conclude that such a combined "omics" approach can be used not only to identify robust biomarkers for novel therapeutics but can also enhance our understanding of downstream signaling pathways; in the example presented here, novel FGF21-mediated signaling events in adipose tissue have been revealed that warrant further investigation. Three mouse strains (C57BL6 on chow diet, C57BL6 on high fat diet, and db/db on chow diet) were treated with either vehicle, wild-type FGF21, or pegylated FGF21 acutely or for several days and three white adipose tissues (IWAT, EWAT, RPWAT) and brown adipose tissue (BAT) were profiled on custom Affymetrix microarrays. The primary goal was to identify robust and consistent acute target engagement biomarkers of FGF21 activation in white adipose tissues.
Project description:Although the well-known importance of pig in agriculture, as well as a model for human biology, the miRNA catalog of pig has been largely undefined. Identification and preliminary characterization of adipose- and muscle-specific miRNAs would be a prerequisite for a thorough understanding of their roles in regulating adipose deposition and muscle growth. In the present study, we get insight into the miRNA transcriptome in eight adipose tissues, two skeletal muscles and cardiac muscle of pig using deep sequencing technology, and to elucidate their characteristic tissue-specific profiles and genomic context. Eleven small RNA libraries from eight adipose tissues, two skeletal muscle tissues and cardiac muscle of pig were sequenced.
