Global changes of gene expression inuced by MIR31HG knockdown

ABSTRACT: Human adipose-derived stem cells (hASCs) are a highly attractive source in bone tissue engineering.We found that MIR31HG significantly promote the osteogenic differentiation of hASCs. However, the underlying mechanisms still await investigations. Thus the alteration of gene expression induced by MIR31HG knockdown was investigated. We used microarrays to detail the global programme of gene expression when MIR31HG was knocked down in hASCs and identified distinct classes of dn-regulated genes during this process.

Genome-wide gene expression during osteogenic and myogenic differentiation from adipose- derived stem cells.

Project description:In the current study, we have performed a gene expression analysis of well characterized and defined populations of human adipose-derived stem cells (hASCs) before and after in vitro induction of osteogenic and myogenic differentiation that allows identifying DNA methylation- regulated differentiation genes. We have also address the extent of the epigenetic programming of hASCs- derived differentiated cells by comparing the expression profiling of these cells with their somatic counterparts from primary tissues. Finally, we also compared the patterns of expression of hASCs (and their derivatives) Identify all genes or probe-sets whose expression was significantly different between control hASCs and each one of the two differentiated cell types (DIF.M and DIF.O),

Genome-wide CpG methylation during osteogenic and myogenic differentiation from adipose- derived stem cells.

Project description:In the current study, we have performed a high-throughput CpG methylation analysis of well characterized and defined populations of human adipose-derived stem cells (hASCs) before and after in vitro induction of osteogenic and myogenic differentiation that allows identifying DNA methylation- regulated differentiation genes. We have also address the extent of the epigenetic programming of hASCs- derived differentiated cells by comparing the methylation profiling of these cells with their somatic counterparts from primary tissues. Finally, we also compared the patterns of CpG methylation of hASCs (and their derivatives) with the methylation profiles of myosarcoma and osteosrcoma cell lines. All the CpG methylation studies have been performed with the Infinium 27K methylation arrays (from Illumina).

Adipose stem cell-derived hepatocyte-like cells from obese patients reveal hepatic steatosis and mitochondrial oxidative dysfunction

Project description:Background & Aims: Obesity is the most important risk factor and a potential treatment target for fatty liver disease (FLD). The continuous adaptation or ‘remodelling’ of hepatic mitochondrial flexibility plays a key role in the pathogenesis of FLD. Human adipose stem cell (hASC)-derived hepatocyte-like cells (HLCs) offer attractive tools for the research and therapy of liver dysfunction. However, evidence showing the ‘remodelling’ of hepatic mitochondrial flexibility or differentiation capability of hASCs in obese patients is lacking. Methods: The differentiation capability and mitochondrial structure and function of hepatic cells were evaluated by measuring gene expression, de novo lipogenesis and mitochondrial respiration in HLCs derived from hASCs of obese patients and lean controls. The ability of the GSK3 inhibitor CHIR-99021 to modify the mitochondrial oxidative dysfunction was evaluated in the HLCs derived from the hASCs of obese patients. Results: hASCs from obese patients showed the potential to differentiate into HLCs. HLCs from the hASCs of obese patients exhibited the characteristics of hepatic steatosis, lower expression of the subunits of mitochondrial complex I and lower oxidative phosphorylation levels. CHIR-99021 promoted the expression of NDUFB8, NDUFB9, the subunits of mitochondrial complex I, and the basal oxygen consumption rate of the HLCs derived from the hASCs of obese patients by upregulating the expression of PGC-1α, the transcription factor involved in mitochondrial biogenesis and ‘remodelling’. Conclusions: The results demonstrate that obese patient ASC-derived HLCs had mitochondrial oxidative dysfunction, which may represent the consequence of hepatic steatosis.

Project description:MicroRNAs play a crucial role in tumorigenesis. However, the value of microRNAs in the diagnosis and treatment of tongue squamous cell carcinoma (TSCC) still await investigations. To identify the microRNAs associated with the metastasis of TSCC, we analyzed the transcriptomic difference between metastatic and the non-metastatic TSCC tissue. We identified a set of metastasis-related microRNAs with potential prognostic value.

Expression data from human placental derived mesenchymal stem cells (PDMSCs)

Project description:When PDMSCs were induced to heptocytes in vitro, cells mophology, stem cell markers, mitochondrial metabolism will change according to the differentiated status.But dedifferentiation reverses differentiated cells to a more primitive phenotype and PDMSCs will retain the multilineage potency. Furthermore, it will leads to the alteration of gene expression pattern. We used microarrays to detail the global programme of gene expression underlying dedifferentiation and hepatogenic differentiation prcocesses, we intend to identify distinct classes of differentiated genes during these processes.

Targeting neddylation is a novel therapeutic strategy for lupus by reconstructing double negative T cell homeostasis

Project description:Systemic lupus erythematosus (SLE) is an autoimmune disorder with systemic inflammation, autoantibody accumulation and organ damage. The abnormalities of double-negative (DN) T cells are considered as an important commander of SLE. Neddylation, an important type of protein post-translational modification (PTM), has been well-proved to regulate T cell-mediated immune response. However, the function of neddylation in SLE remains largely unexplored. Here, we reported that neddylation inactivation with MLN4924 or genetic abrogation of Ube2m in T cells prevented SLE development for decreased DN T cell accumulation. Further investigations revealed that inactivation of neddylation blocked Bim ubiquitination degradation and maintained Bim level in DN T cells, contributing to the apoptosis of the accumulated DN T cells for Fas mutation. Then double knockout (KO) lupus-prone mice (Ube2m-/-Bim-/-lpr) were generated and results showed that loss of Bim interrupted the improvement of DN T cell apoptosis and the consequential relieved lupus symptoms for Ube2m KO. Our findings identified that neddylation inactivation promoted Bim-mediated apoptosis of DN T cells and prevented lupus progress. Clinically, we also found the percentages of DN T cells were improved accompanied with reduced apoptosis of DN T cells in SLE patients. Moreover, the neddylation of Cullin1 was higher while Bim level was decreased in SLE patients compared with healthy control. Meantime, the inhibition of neddylation induced Bim-dependent apoptosis of DN T cells isolated from SLE patients. Together, these findings provide the first evidence of the neddylation role in lupus development, suggesting a novel therapeutic strategy for lupus.

TGFβ1 determines the fate of human adipose-derived stromal cells by restraining their immaturity and white/beige adipocyte potentials

Project description:Human adipose-derived stem/stromal cells (hASCs) can differentiate into a large broad of specialized cell types to ensure homeostasis of tissues. Thus, they are drawing increasing attention in cell therapy and regenerative medicine. However, culture conditions are still critical to ensure their regenerative capabilities. Here we compared Standard conditions (αMEM containing 10% fetal bovine serum) and Endothelial cell Growth Medium 2 (EGM2) containing few serum (2% v/v) for expansion of hASCs. Both types of hASCs were exhaustively characterized by high throughput studies, Gene Set Enrichment Analyses (GSEA) and differentiation potentials experiments. EGM2-hASCs showed enhanced multipotency and their phenotype was more immature than Standard-hASCs. The adipogenic potential of EGM2-hASCs was clearly more extented, including toward the thermogenic beige adipocyte fate. Data from microarray and GSEA highlighted Transforming Growth Factor β1 (TGFβ1) as upstream factor influencing the becoming of Standard-hASCs which is consistent with higher TGFβ1 content in Standard medium. This was associated with nuclear SMAD3 localization and higher expression of its active form in Standard-hASCs. Moreover, these cells were primed into osteoblast, chondroblast and Vascular Smooth Muscle (VSM) lineages at the expense of their adipogenic potential. Their treatment with TGFβ1 receptor inhibitors resulted in a cytoplasmic re-localization of SMAD3 and a decrease of VSM and osteoblastic lineages markers, increasing in turn their beige adipogenic potential. Therefore, TGFβ1 is a key factor committing hASCs toward osteo-chondroblastic and VSM lineages at the expanse of their beige adipogenic potential. Thanks to low TGFβ1 content, EGM2 medium improves the maintenance of uncommitted hASCs with strong beige adipocyte potential. We used microarrays to unravel differential gene expressions between human ASCs cultured in standard conditions or in EGM2 medium.
