Project description:Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process. We extractedbrown and white primary adipocytes and pre-adipocytes and profiled lncRNA expresssion via mRNA-Seq. We also profiled cultured, differentiated adipocytes to verify that we could recapitulate the adipocyte expression profile in preparation for a loss-of-function screen for essential adipogenic lincRNAs.

We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process. We profiled knockdown of lncRNAs that are upregulated during mouse adipocyte development We compared adipocytes differentiated in vitro after knockdown of 10 lncRNAs against control adipocytes and pre-adipocytes using Affymetrix expression microarrays. When cultured primary-preadipytes reached 70-80% confluence, we transfected siRNAs against each lincRNA. 24 hours after transfection, cells were recovered in full culture media and grown to confluence for differentiation. Total RNA was collected from control pre-adipocytes (D0) prior to differentation. Four days after recovery, total RNA was collected from each knockdown, a scramble control, and an untransfected control (D4).

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:Human antigen R (HuR) protein, a RNA binding protein (RBP), has been reported to regulate essential steps in RNA metabolism and immune response in a variety of cell types, but its function in metabolism remains unclear. This study identifies HuR as a major repressor during adipogenesis. Knockdown and overexpression of HuR in primary adipocyte culture enhances and inhibits adipogenesis in vitro, respectively. Fat-specific knockout of HuR significantly enhances adipogenic gene program in all three major adipose tissues including epidydimal, inguinal white and brown adipose tissue, accompanied with systemic glucose intolerance and insulin resistance. Conversely, transgenic overexpression of HuR in adipose tissue prevents the HFD induced obesity by repressing adipogenesis. Mechanistically, HuR may inhibit adipogenesis by recognizing and modulating the stability of hundreds of adipocyte transcripts, including the mRNA of Insig1, a negative regulator during adipogenesis. Taken together, our work establishes HuR as a novel posttranscriptional regulator of adipogenesis and provides a new insight into how RNA processing contributes to adipocyte development.

Project description:Recents studies in mice and humans demonstrated the relevance of H2S-synthesising enzymes (such as CTH, CBS and MPST) in adipose tissue physiology and preadipocyte differentiation into adipocytes. Here, we aimed to investigate the combined role of CTH, CBS and MPST in the preservation of adipocyte protein persulfidation and adipogenesis. Joint CTH, CBS and MPST gene knockdown was achieved treating fully human adipocytes with siRNAs against these transcripts (siRNA_MIX). Adipocyte protein persulfidation was analyzed by a mass spectrometry label-free quantitative approach coupled with a dimedone-switch method for protein labeling and purification. The proteomic analysis quantified 216 proteins with statistically different persulfidation levels in KD cells compared to control adipocytes. In fully differentiated adipocytes, CBS and MPST mRNA and protein levels were abundant, whereas CTH expression was very low. Of note, siRNA_MIX administration resulted in a significant decrease in CBS and MPST expression, without impacting on CTH. Dual CBS and MPST gene knockdown resulted in decreased expression of relevant genes for adipocyte biology, including adipogenesis, mitochondrial biogenesis and lipogenesis, but increased proinflammatory- and senescence-related genes, in parallel to a significant disruption in adipocyte protein persulfidation pattern. While among less persulfidated proteins, we identified several relevant proteins for adipocyte adipogenesis and function, among the most persulfidated, key mediators of adipocyte inflammation and dysfunction, but also some proteins that might have a positive role of adipogenesis were found. In conclusion, current study indicates that joint knockdown of CBS and MPST (but not CTH) in adipocytes impairs adipogenesis and promotes inflammation, possibly by disrupting the pattern of protein persulfidation in these cells, and suggesting that these enzymes were required for the functional maintenance of adipocytes.

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:Background: Obesity is characterized as a disease that directly affects the whole-body metabolism and is associated with excess fat mass and several related comorbidities. Dynamics of the adipocyte hypertrophy and hyperplasia play an important role in health and disease, especially in obesity. Human adipose-derived stem cells (hASC) represent an important source for understanding the entire adipogenic differentiation process. However, little is known about the triggering step of adipogenesis in hASC. Here, we performed a proteogenomic approach for understanding the protein abundance alterations expression changes during the initiation of the adipogenic differentiation process. Methods: hASC were isolated from adipose tissue from three donors, characterized and expanded. Cells were cultured for 24 hours in adipogenic differentiation medium followed to protein extraction. We used shotgun proteomics to compare the proteomic profile of 24h-adipogenic differentiated and undifferentiated hASC. Besides, we used our previously next-generation sequencing data (RNA-seq) from the total and polysomal mRNA fractions of hASC to study post-transcriptional regulation during the initial steps of adipogenesis. Results: We identified a total of 3,.420 proteins out of and 48,.336 peptides, being 92 exclusively identified proteins in the undifferentiated hASC and 53 exclusive proteins in 24h-differentiated cells. Using a stringent criterion, we identified 33 differentially abundant proteins when compare 24h-differentiated versus undifferentiated hASC (14 upregulated and 19 downregulated, respectively). Among the upregulated proteins, we shortlist identified several adipogenic-related proteins. Combined analysis of the proteome and the transcriptome allowed the identification of positive correlation coefficients between proteins and mRNAs. Conclusions: These results demonstrate a specific proteome profile related to adipogenesis at the very beginning (24h) of the differentiation process in hASC, which represents an important piece for a better understanding of human adipogenesis and obesity. In addition, the adipogenic differentiation is fine-tuning regulated at transcriptional, post-transcriptional and post-translational levels.
