Project description:Cellular dedifferentiation signifies the withdrawal of cells from a specific differentiated state into a M-bM-^@M-^Xstem cellM-bM-^@M-^Y-like undifferentiated state. However, the mechanism of dedifferentiation remains obscure. We showed that mature adipocytes (MA) and follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency. We investigated the dedifferentiation mechanism of MA and GC using global gene expression analyses. Using Affymetrix porcine genome array, we compared global gene expression profiles during dedifferentiation to search for particular biological functions in genes of which expression intensities were increased or decreased by MA and GC dedifferentiation.

Project description:In mammals, terminally differentiated cells are generally incapable of reversing the differentiation process. We showed that adipocytes (AC), which is a terminally differentiated cell type, can dedifferentiate during culture in vitro and acquire multipotency. We investigated the dedifferentiation mechanism of AC using global gene expression analyses.

Project description:Cellular dedifferentiation signifies the withdrawal of cells from a specific differentiated state into a ‘stem cell’-like undifferentiated state. However, the mechanism of dedifferentiation remains obscure. We showed that mature adipocytes (MA) and follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency. We investigated the dedifferentiation mechanism of MA and GC using global gene expression analyses.

Project description:It is widely recognized that cancer development and progression depend not only on tumor-cell intrinsic factors but also on its microenvironment and on the host characteristics. Adipocytes are the main stromal cells in the breast and an heterotypic interaction between breast epithelial cells and adipocytes has been demonstrated. To date, the alterations associated with adipocyte dedifferentiation has to be further studied. The aim of our work is to compare gene expression profile of mature adipocytes (MA), adipocytes dedifferentiated (DED) by breast cancer cells and mesenchymal stem cells (MSC) using the ASC52htert in vitro model.

Project description:White adipose tissue (WAT) is a central factor in the development of type 2 diabetes. Despite the epidemiological importance of WAT there is a paucity of translational models to study long term changes in mature adipocytes. Here, we describe a novel method for the culture of mature white adipocytes under a permeable membrane. Compared to existing culture methods such as adipose tissue explants and adipocyte ceiling culture, Membrane mature Adipocyte Aggregate Cultures (MAAC) are superior at maintaining adipogenic gene expression through 2 weeks of culture, do not dedifferentiate, and are under reduced hypoxic stress relative to adipose tissue explants. Unbiased RNA-Sequencing analysis indicates that the gene expression profile of MAAC in culture for 1 or 2 weeks is more similar to starting patient material than cultured adipose tissue explants, floating adipocytes, or in vitro-differentiated precursors from the same donor, with the fewest number of differentially expressed genes and the smallest fold-change in gene expression. Importantly, adipocytes from lean and obese patients can be cultured as MAAC, as can subcutaneous and visceral adipocytes, while maintaining depot-specific gene expression signatures. MAAC remain fully functional after long term culture, with similar responses to insulin and lipolytic stimuli compared to recently isolated cells. In addition, MAAC maintain the ability to crosstalk with other cell types, producing synergistic increases in IL6 and IL8 when co-cultured with macrophages, and respond robustly and predictably to diverse pharmacological agonism. Together, these abilities make MAAC a powerful tool for studying phenotypic changes in mature adipocytes, crosstalk between adipocytes and other cell types, and provide an improved translational model for drug development for the modulation of adipose tissue function.

Project description:The CCR4-NOT deadenylase complex has a critical function to trigger mRNA decay and various biological events. To understand roles of the complex in adipocyte function, we compare mRNA half-lives between control and Cnot complex-deficient mature adipocytes from iWAT and BAT.

Project description:We took a systematic approach to determine the transcriptional programs that are specifically regulated by C/EBPα in mature white adipocytes of mice on chow diet or high fat diet. The hypothesis tested in the present study was that C/EBPα, as a lipogenic transcription factor, has unique direct targets compared to PPARγ. Our inducible adipocyte specific knockout system allows us to test the direct targets of C/EBPα and PPARγ in adipocytes by short-term C/EBPα or PPARγ elimination in mature adipocytes in vivo. Results indicate that although it has been shown that C/EBPα and PPARγ cross-regulate each other, they have distinct direct responsive targets. Moreover, there are very few C/EBPα specific targets in mice on a chow diet, most of the C/EBPα targets in mature adipocytes are genes modulated by HFD feeding.
