Project description:White adipocytes function as the major energy reservoir in humans by storing large amounts of triglycerides. Their dysfunction is associated with metabolic disorders. However, the mechanisms underlying cellular specialization during adipogenesis remain unknown. Here, we generated a spatiotemporal proteomic atlas of human adipogenesis to gain insights into cellular remodeling and the spatial reorganization of metabolic pathways to optimize cells for lipid accumulation. Our study highlights the coordinated regulation of protein localization and abundance during adipogenesis. More specifically, we identified a compartment-specific regulation of protein levels to reprogram branched chain amino acid and one-carbon metabolism to provide building blocks and reduction equivalents for lipid synthesis. Additionally, we identified C19orf12 as a differentiation induced adipocyte-specific lipid droplet (LD) protein, which interacts with the translocase of the outer membrane (TOM) complex of LD associated mitochondria and modulates adipocyte lipid storage. Overall, our study provides a comprehensive resource for understanding human adipogenesis and for future discoveries in the field.

Project description:To investigate the collective role of zinc finger proteins in adipogenesis, we induced adipogenesis using human mesenchymal stem cells (MSC) and compared the gene expression profiles using human Illumina beads arrays. We performed three independent experiments of time-series analysis (0h, 1h, 12h, 24h, 2d, 4d, 6d, 9d, 12d, 15d after induction of adipogenesis) in order to comprehensively capture the dynamic profiles of transcriptome during differentiation. Statistical filtering based on Analysis of Variance (ANOVA; p-value < 0.001, FDR 5%) and Gene Ontology classification using the Human Gene Nomenclature Database (HGNC) identified 618 out of 678 zinc finger proteins (ZFPs) that were significantly expressed during adipogenesis. Moreover, 34 out of 618 genes were differentially expressed more than 2-fold up or down regulated. The K-means clustering analysis further revealed four dynamic expression patterns: one gene in early-response, seven genes in transient, twenty genes in progressively-induced and four genes in the down-regulated, demonstrating the dynamic involvement of ZFPs in the process of adipocyte differentiation and maturation. Total RNA obteind from 10 different time points (0h, 1h, 12h, 24h, 2d, 4d, 6d, 9d, 12d, 15d) during adipogenesis from human Mesenchymal stem cell (MSC) to Adipocyte (ADP). Adipogensis was induced by the different cocktail of chemical compunds containing human-insulin, dexamethasone, indomethacin and IBMX.

Project description:We depicted a genome-wide integrative view of DNA methylome by reduced representation bisulfite sequencing (RRBS) and transcriptome by RNA-seq during brown and white adipocyte differentiation. Our analysis demonstrated that DNA methylation is a stable epigenetic signature for brown and white cell lineage before, during and after differentiation. When comparing white to brown adipocytes at all three time points of differentiation, we identified five members of the Hox family whose expression levels were anti-correlated with promoter methylation, suggesting a regulatory role of DNA methylation in transcription.

Project description:The pervasive expression of circular RNA from protein coding loci is a recently discovered feature of many eukaryotic gene expression programs. Computational methods to discover and quantify circular RNA are essential to the study of the mechanisms of circular RNA biogenesis and potential functional roles they may play. In this paper, we present a new statistical algorithm that increases the sensitivity and specificity of circular RNA detection.by discovering and quantifying circular and linear RNA splicing events at both annotated exon boundaries and in un-annotated regions of the genome Unlike previous approaches which rely on heuristics like read count and homology between exons predicted to be circularized to determine confidence in prediction of circular RNA expression, our algorithm is a statistical approach. We have used this algorithm to discover general induction of circular RNAs in many tissues during human fetal development. We find that some regions of the brain show marked enrichment for genes where circular RNA is the dominant isoform. Beyond this global trend, specific circular RNAs are tissue specifically induced during fetal development, including a circular isoform of NCX1 in the developing fetal heart that, by 20 weeks, is more highly expressed than the linear isoform as well as beta-actin. In addition, while the vast majority of circular RNA production occurs at canonical U2 (major spliceosome) splice sites, we find the first examples of developmentally induced circular RNAs processed by the U12 (minor) spliceosome, and an enriched propensity of U12 donors to splice into circular RNA at un-annotated, rather than annotated, exons. Together, our algorithm and its results suggest a potentially significant role for circular RNA in human development. 35 human fetal samples from 6 tissues (3 - 7 replicates per tissue) collected between 10 and 20 weeks gestational time were sequenced using Illumina TruSeq Stranded Total RNA with Ribo-Zero Gold sample prep kit.
