Transcriptomic analyses of the anti-adipogenic and pro-osteoblastic effects of aspirin in rat bone mesenchymal stem cell

Project description:Theoretically, the differentiation of mesenchymal stem cells (MSCs) into either adipocytic or osteoblastic phenotype can be deemed as a seesaw, where induction of one lineage comes at the expense of the other. Previously, researchers, including our team, found that aspirin promoted osteoblast differentiation of bone mesenchymal stem cells (BMSCs) whereas inhibiting adipogenic differentiation. However, the precise mechanisms, that is, which pathways, what biological process or key genes involved during this process, had not been systematically studied. In the present study, we tend to analyze the whole transcriptome of the anti-adipogenic and promote-osteoblastic effects of aspirin in BMSCs. Our results showed that aspirin’s presence restored or further strengthened the expression of an important part of the gene population repressed during adipogenesis or increased during osteogenesis. Besides, classical pathways related to osteogenic differentiation (p53 signaling pathway, focal adhesion, osteoclast differentiation, PI3K-Akt signaling pathway, MAPK signaling pathway, and Wnt signaling pathway) and the fat metabolism were also disturbed during the promote-osteoblastic and anti-adipogenic effects of aspirin. Therefore, our whole-genome transcriptomic results shed new light and open the door to more specific “omics” studies. Our results allow a better understanding of the anti-adipogenic and promote-osteoblastic effects of aspirin and pave the way to aspirin clinical use for the prevention and treatment of diseases like tissue defect and osteoporosis.

Mouse polycomb group gene Cbx2 promotes osteoblastic but suppresses adipogenic differentiation in postnatal long bones

Project description:A set of key developmental genes is essential for skeletal growth from multipotent progenitor cells at weaning. Polycomb group proteins, which regulate such genes contributes to the cell lineage commitment and subsequent differentiation via epigenetic chromatin modification and remodeling. However, it is unclear which cell lineage and gene sets are targeted by polycomb proteins during skeletal growth. We now report that mice deficient in a polycomb group gene Cbx2 (cterm/cterm) exhibited skeletal hypoplasia in the tibia, femur, and cranium. Long bone cavities in these mice contained fewer multipotent mesenchymal stromal cells. RNA-sequencing of bone marrow cells showed downregulation and upregulation of osteoblastic and adipogenic genes, respectively. Furthermore, the expression levels of genes specifically expressed in B-cell precursors were decreased. Forced expression of Cbx2 in Cbx2 (cterm/cterm) bone marrow stromal cell recovered fibroblastic colony formation and suppressed adipogenic differentiation. Collectively, our results suggest that Cbx2 controls the maintenance and adipogenic differentiation of mesenchymal stromal cells in the bone marrow.

Aspirin Challenge–Induced Genome-Wide DNA Methylation Profile of Peripheral Blood Lymphocytes in Aspirin-Exacerbated Respiratory Disease

Project description:Oral aspirin challenge may induce different global CpG methylation patterns between aspirin-exacerbated respiratory disease (AERD) and aspirin-tolerant asthma (ATA), which may affect gene expression several hours later. Therefore, in the present study, we compared global CpG methylation profiles before and after an oral aspirin challenge in patients with asthma. In addition, we compared differences in methylation profiles between AERD and ATA using an Illumina 860K Infinium Methylation EPIC BeadChip array platform, which had greater coverage than in the previous study (26,485 CpGs) to discover new methylated CpGs in PBLs associated with aspirin-induced bronchospasm.

Fibroblasts under adipogenic, chondrogenic or osteogenic differentiation medium and controls

Project description:Global gene expression analysis was performed to investigate the changes of the fibroblast phenotype after four-week inductions toward adipocytic, osteoblastic and chondrocytic lineages. Human cells. Differential gene regulation, interpreted through Gene Set Enrichment Analysis, highlight important similarities and differences of induced fibroblasts compared to control cultures of human fibroblasts, adipocytes, osteoblasts and articular chondrocytes. Fibroblast controls were compared to Adipogenic induced fibroblasts and adipocytes. Gene sets were analysed with GSEA (webgestalt). Repeated for each lineage.

Transcriptomic analyses of anti-adipogenic effects of oleuropein in human mesenchymal stem-cells

Project description:The main goal of the present work was to use an in vitro adipogenic-differentiation mode, with mesenchymal stem-cells (MSC) from human bone-marrow, to study whole-transcriptomic differential gene-expression when such cells are induced to differentiate into adipocytes in absence or presence of oleuropein. See details below. This work is complementary to a previously published one (Casado-Daz et al, 2016): Casado-DÃaz, A., Anter, J., MÃ¼ller, S., Winter, P., Quesada-GÃ³mez, J. M. and Dorado, G. (2016): Transcriptomic analyses of adipocyte differentiation from human mesenchymal stromal-cells (MSC). Journal of Cellular Physiology 9999: 1-14. DOI: 10.1002/jcp.25472. It corresponds to EMBL-EBI ArrayExpress accession E-MTAB-4884.

Half-lives of aspirin-mediated lysine acetylations

Project description:Aspirin, or acetylsalicylic acid is widely used to control pain, inflammation and fever. An important property of aspirin is its ability to acetylate multiple cellular proteins with some pharmacological functions explicable by the irreversible acetylation of cyclooxygenases at active site serine residues. We have used a labeled form of aspirin, aspirin-d3 to acetylate proteins in cultured human cells, and unambiguously identified over 12000 sites of acetylation, using acetylated lysine peptide enrichment combined with mass-spectrometry-based proteomics. Aspirin increases lysine acetylation occupancy of the majority of detected endogenous sites, but leaves almost unchanged a small group that are already highly acetylated. We show that cells are remarkably tolerant of this acetylation insult unless endogenous deacetylases are inhibited. This work raises the possibility that rather than single protein effects, some of the clinical features of aspirin may be the consequence of multiple concurrent protein modifications, and that combining aspirin with lysine deacetylase inhibitors may have important medical implications.

Multi-omics Study Reveals the Synergistic Anti-tumor Effects of Aspirin and Gemcitabine-based Chemotherapy on Pancreatic Cancer and the Underlying Mechanism

Project description:Pancreatic cancer is a highly malignant tumor that is well known for its poor prognosis. It has been reported that aspirin can reduce the risk of various cancers, but the potential role of aspirin and gemcitabine in pancreatic cancer pathogenesis and chemotherapy has not been studied.

STOX1 placenta w/o aspirin

Project description:STOX1 overexpressing placentas generate preeclampsia-like symptoms in pregnant mice. These symptoms are reverted by aspirin. The experiment aims at analyzing placental expression in Transgenic/non transgenic with and withou aspirin, in the placentas at 16,5 days post-coïtum. There are two strains of transgenic mice that express the transgene at different levels: STOX42 about 15 fold that of STOX13. STOX13 expressed the human STOX1 roughly at the level of the mouse endogeneous Stox1 in the placenta.
