Project description:To identify osteoblast specific miRNAs that can contribute to osteoblastogenesis by post-transcriptionally regulates their targets, BMP2 are treated to C2C12 for 72 hours and performed miRNA microarray. C2C12 cells were treated with vehicles or BMP2 (300 ng/mL) supplemented alpha-MEM media for 72 days and total RNA was harvested and performed exiqon miRNA microarray. Duplicates were used for each condition. Dye swaps were done.

Project description:Bone morphogenetic proteins (BMPs) regulate many aspects of skeletal development, including osteoblast and chondrocyte differentiation, cartilage and bone formation, and cranial and limb development. Among them, BMP2, one of the most potent osteogenic signaling molecules, stimulates osteoblast differentiation, while it inhibits myogenic differentiation in C2C12 cells.

Project description:Background: MicroRNAs (miRNAs) are a family of small, non-coding single-stranded RNA molecules involved in post-transcriptional regulation of gene expression. As such, they are believed to play a role in regulating the step-wise changes in gene expression patterns that occur during cell fate specification of multipotent stem cells. Here, we have studied whether terminal differentiation of C2C12 myoblasts is indeed controlled by lineage-specific changes in miRNA expression. Results: Using a previously generated RNA polymerase II (Pol-II) ChIP-on-chip dataset, we show differential Pol-II occupancy at the promoter regions of six miRNAs during C2C12 myogenic versus BMP2-induced osteogenic differentiation. Overexpression of one of these miRNAs, miR-378, enhances Alp activity, calcium deposition and mRNA expression of osteogenic marker genes in the presence of BMP2. Conclusions: Our results demonstrate a previously unknown role for miR-378 in promoting BMP2-induced osteogenic differentiation. Stable C2C12 cell lines C2C12-pMirn0 and C2C12-pMirn378 were generated by lentiviral transduction of C2C12 myoblasts with a Mirn378-overexpression construct and its parent vector, respectively. C2C12-pMirn0 and C2C12-pMirn378 cells were plated at 2.5 x 10^4 cells/cm2 (day -1), cultured for 1 day in DMEM 10%NCS, then (d0) treated with or without 300 ng/ml bone morphogenetic protein 2 (BMP2) for 6 days. RNA was extracted on d0, d3 and d6 and hybridized to GeneChip Mouse Genome 430 2.0 array (Affymetrix).

Project description:Differentiation of pluripotent embryonic stem cells, via more restricted multipotent adult stem cells, towards the multitude of terminally differentiated, specialized cell types that make up the adult body is a multi-step process characterized by a progressive restriction of differentiation potential. Previous studies have demonstrated tissue-specific differences in DNA methylation patterns that might play a role in lineage restriction and tissue-specific gene expression. However, these studies have mainly focused on either the differentiation of pluripotent ES cells or on comparing somatic cells from different tissues, so that it remains unclear at which stages during development these differences in DNA methylation profiles are established. Since data on the role of DNA methylation during late-stage development is limited, we have examined the role of this epigenetic mark during the terminal differentiation of a multipotent adult stem cell, using C2C12 as a model system. Using parallel MeDIP- and Pol-II ChIP-on-chip approaches, we demonstrate a mutually exclusive relationship between high Pol-II occupancy and high DNA methylation levels. In addition, we observe that in undifferentiated progenitor cells, osteoblast-related genes have in general higher methylation levels than myoblast-related genes, while myoblast-related genes have higher Pol-II occupancy. Induction of osteogenesis with BMP2 leads to a rearrangement of Pol-II towards osteoblast-related genes. However, methylation patterns remain unchanged. These results indicate that DNA methylation primes C2C12 multipotent stem cells for myogenic differentiation and permits induction of the osteogenic gene expression program upon growth factor stimulation. We propose that cell type-specific DNA methylation patterns are established prior to terminal differentiation of adult stem cells.

Project description:Enhanced BMP or canonical Wnt (cWnt) signaling are therapeutic strategies employed to enhance bone formation and fracture repair, but the mechanisms each pathway utilizes to specify cell fate of bone-forming osteoblasts remain poorly understood. Among all BMPs expressed in bone, we find that singular deficiency of Bmp2 blocks the ability of cWnt signaling to specify osteoblasts from limb bud or bone marrow progenitors. When exposed to cWnts, Bmp2-deficient cells fail to progress through the Runx2/Osx1 checkpoint and thus do not upregulate multiple genes controlling mineral metabolism in osteoblasts. Cells lacking Bmp2 after induction of Osx1 differentiate normally in response to cWnts, supporting pre-Osx1+ osteoprogenitors as a critical source and target of BMP2. Our analysis furthermore reveals Grainyhead-like 3 (Grhl3) is to date an unidentified transcription factor in the osteoblast gene regulatory network that is induced during bone development and bone repair, and acts upstream of Osx in a BMP2-dependent manner. The Runx2/Osx1 transition therefore receives critical regulatory inputs from BMP2 that are not compensated for by cWnt signaling, and this is mediated at least in part by induction and activation of Grhl3.

Project description:This study analyses the gene expression profile of pre-osteoblastic C2C12 mice cells during osteodifferentiation in control and induced by rhBMP2 and rhBMP7 using DNA microarrays. Genes which were already known to be activated by BMP2, to be also activated by rhBMP7, indicating that BMP7 induces these genes in a similar fashion as BMP2. Moreover, we identified some new genes, such as Hoxc8, Glis1, Glis3, Ecsit, LrP6, Dvl1, Grn, BMP1, Ltbp2, Plod1, Htra1 and IGFBP-rP10, to be upregulated by both rhBMPs. Total RNA from mouse pre-myoblastic and pre-osteoblastic C2C12 cell line, after 12h of treatment with rhBMP2 and rhBMP7, was hybridized to a microarray and analyzed.
