Accumulation of adipocytes and collagen type-I-producing cells (fibrosis) is observed in muscular dystrophies. The origin of these cells had been largely unknown, but recently we identified mesenchymal progenitors positive for platelet-derived growth factor receptor alpha (PDGFRα) as the origin of adipocytes in skeletal muscle. However, the origin of muscle fibrosis remains largely unknown. In this study, clonal analyses show that PDGFRα(+) cells also differentiate into collagen type-I-producing ...[more]

Separation of mouse ES cell-derived mesodermal cells based on the expression of Flk1, PDGFRa and CAR.

Project description:We found that mouse ES cell-derived Flk1+ cells could be subdivided into three population by the expression of PDGFRa and CAR (Flk1+PDGFRa-CAR-, Flk1+PDGFRa-CAR+, and Flk1+PDGFRa+CAR+). Therefore, global gene expression analysis was perfomed by microarray to characterize these mesodermal subsets. RNA isolated from five separate experiments was pooled and used for comparison

Changes of miRNAs during osteogenic differentiation of PDGFRa+ mesenchymal progenitors derived from human skeletal muscle

Project description:Comprehensive analyses of miRNAs expression were performed using miRNA microarrays during osteogenic differentiation of PDGFRa+ mesenchymal progenitors isolated from human skeletal muscle to identify miRNAs that are involved in osteogenesis of PDGFRa+ mesenchymal progenitors. PDGFRa+ mesenchymal progenitors were isolated from the gluteus medius muscles of two different patients, and then subjected to osteogenic induction. Expression of miRNAs was examined using miRNA microarrays at the time points of one week and two weeks after osteogenic induction and were compared with that of uninduced cells.

Constitutive activation of oncogenic PDGFR-mutants found in GIST patients induces receptor mislocalisation and alters PDGFR-A signalling characteristics

Project description:Gastrointestinal stomal tumors (GIST) are mainly characterised by the presence of activating mutations in either of the two receptor tyrosine kinases c-KIT and Platelet-derived growth factor receptor-a (PDGFRa). Most mechanistic studies dealing with GIST mutations have focused on c-KIT and far less is known about the signalling characteristics of the mutated PDGFRa proteins. Comparative studies of the signal transduction capacities of different mutant proteins cannot be performed in patient cells due to the patient specific background which may influence the signalling behaviour of the investigated mutants. In addition, the lack of a real wild-type signalling control (PDGFRa-WT) hampers comparisons of the signalling of wild-type and mutant proteins. Therefore, we stably and inducibly expressed different PDGFRa mutants as well as wild-type PDGFRa on an isogenic background in 293T cells in order to study the signalling capacities and corresponding transcriptional responses of the different proteins. We found that the constitutive signalling via the oncogenic PDGFRa mutants favours a mislocalisation of the receptors and that this modifies the signalling characteristics of the mutated receptors. We show that signalling via the oncogenic PDGFRa mutants is not solely characterised by a constitutive activation of the conventional PDGFRa signalling pathways.

Fibronectin regulates Wnt7a signaling and satellite cell expansion

Project description:The influence of the extracellular matrix (ECM) within the stem cell niche remains poorly understood. We found that Syndecan-4 (Sdc4) and Frizzled-7 (Fzd7) form a coreceptor complex in satellite cells and that binding of the ECM glycoprotein Fibronectin (FN) to Sdc4 stimulates the ability of Wnt7a to induce the symmetric expansion of satellite stem cells. Newly activated satellite cells dynamically remodel their niche via transient high-level expression of FN. Knockdown of FN in prospectively isolated satellite cells severely impaired their ability to repopulate the satellite cell niche. Conversely, in vivo overexpression of FN with Wnt7a dramatically stimulated the expansion of satellite stem cells in regenerating muscle. Therefore, activating satellite cells remodel their niche through autologous expression of FN that provides feedback to stimulate Wnt7a signaling through the Fzd7/Sdc4 coreceptor complex. Thus, FN and Wnt7a together regulate the homeostatic levels of satellite stem cells and satellite myogenic cells during regenerative myogenesis. The data set contains one microarray of pooled quiescent skeletal muscle satellite cells

Oncogenic FIP1L1-PDGFR-alpha signaling: influence of subcellular localisation and unconventional STAT activation

Project description:Aberrant activation of oncogenic kinases is frequently observed in human cancers, but the underlying mechanism and resulting effects on global signaling are incompletely understood. Here, we demonstrate that the oncogenic FIP1L1-PDGFRa kinase exhibits a significantly different signaling pattern compared to PDGFRa wildtype: Interestingly, the conventional strong activation of PI3-kinase- and MAP-kinase- pathways is remarkably shifted towards a prominent activation of STAT factors. This diverging signaling pattern compared to classical PDGF-receptor signaling is partially coupled to the aberrant intracellular location of the oncogene, since membrane targeting of F/PDGFRa restores activation of MAPK- and PI3K-pathway completely. In contrast to the M-^SclassicalM-^T cytokine-induced STAT-activation process does STAT activation by F/PDGFR not require Janus kinase activity and does not involve a SH2-domain-mediated binding mechanism. Thus it is conceivable that STAT activation by F/PDGFR could be directly mediated by interaction of STAT factors with the kinase domain itself.

CD140a+ human glial progenitor cells

Project description:Glial progenitor cells (GPCs) pervade the human brain. These cells express gangliosides recognized by MAb A2B5, and some but not all can generate oligodendrocytes. Since some A2B5+ GPCs express PDGFa receptor (PDGFRa), which is critical to oligodendrocyte development, we asked if PDGFRa-directed sorting might isolate oligodendrocyte-competent progenitors. We used FACS to sort PDGFRa+ cells from the second trimester fetal human forebrain, based on expression of the PDGFRa epitope CD140a. CD140a+ cells could be maintained as mitotic progenitors that could be instructed to either oligodendrocyte or astrocyte phenotype. Transplanted CD140a+ cells robustly myelinated the hypomyelinated shiverer mouse brain. Microarray confirmed that CD140a+ cells differentially expressed PDGFRA, NG2, OLIG1/2, NKX2.2 and SOX2. Some expressed CD9, thereby defining a CD140a+/CD9+ fraction of oligodendrocyte-biased progenitors. CD140a+ cells differentially expressed genes of the PTN-PTPRZ1, wnt, notch and BMP pathways, suggesting the interaction of self-renewal and fate-restricting pathways in these cells, while identifying targets for their mobilization and instruction. 10 samples, 5 CD140a+, and 5 CD140a- sorted samples for individual fetal human brain

Comparing gene expression between PICs and satellite cells from 1 week old muscle

Project description:The satellite cell is considered the major tissue-resident stem cell underlying muscle regeneration, however, multiple non-satellite cell myogenic progenitors have been identified. PW1/Peg3 is expressed in satellite cells as well as a subset of interstitial cells with myogenic potential termed PICs (PW1+ Interstitial Cells). PICs differ from satellite cells by their anatomical location (satellite cells are sublaminal and PICs are interstitial), they do not express any myogenic marker and arise from a Pax3-independent lineage. Upon isolation from juvenile muscle (1 to 3 weeks old), PICs are capable to form both skeletal and smooth muscle suggesting they constitute a more plastic population compared to satellite cells. We used microarrays to gain insight into the relantionship between PICs and satellite cells. PICs and satellite cells were isolated from 1-week old mouse muscle and subsequent RNA extraction was performed.

SUV420H2 over-expression affects on gene expression in human breast cancer MDA-MB-231 cells

Project description:Analysis of breast cancer MDA-MB-231 cells stably over-expressing SUV420H2, a histone H4K20 methyltransferase. Several genes were significantly up- or down-regulated. Results provide insight into the molecular mechanism by which H4K20me3 contributes to gene expression. SUV420H2 stably over-expressing MDA-MB-231 cells were cloned. Then total RNA was extracted from the SUV420H2 over-expressing cells and the parental MDA-MB-231 cells.
