Global quantitative proteomics analysis reveals the downstream signaling networks of Msx1 and Msx2 in skeletal muscle development

Project description:The homeoprotein Msx1 and Msx2 involved in normal skeletal muscle development and also contribute to muscle defects if altered during development. Deciphering the downstream signaling networks of Msx1 and Msx2 in myoblasts differentiation will help us to understand the molecular events that contribute to muscle defects. The objective of this study was to evaluate the proteomics characteristics in Msx1 and Msx2 mediated myoblasts differentiation, using isobaric tags for the relative and absolute quantification labelling technique (iTRAQ). The results showed that 1535 proteins with quantitative information were obtained. Volcano plots illustrated, in undifferentiated stage, 32 common downstream regulatory proteins for Msx1 and Msx2, 39 specific regulatory proteins for Msx1, and 13 specific for Msx2. While, in differentiated stage, 17 common downstream regulatory proteins for Msx1 and Msx2, 10 specific regulatory proteins for Msx1, and 21 specific for Msx2. Gene ontology, KEGG pathway and protein-protein interaction networks analyses revealed these proteins primarily associated with Arginine and proline metabolism, Glycolysis/Gluconeogenesis, Fatty acid degradation, Metabolism of xenobiotics by cytochrome P450 and Apoptosis. In addition, our data shows Acta1 was probably a core of the downstream regulatory networks of Msx1 and Msx2 in skeletal muscle development. The findings will help us to understand the molecular roles of Msx1 and Msx2 during muscle development as well as regeneration, and to understand the molecular events that contribute to muscle defects.

MSX1-induced neural crest-like phenotype in human melanocytes

Project description:Msh homeobox 1 (MSX1) is a transcription factor implicated in neural crest specification. Ectopic expression of MSX1 reprograms mature melanocytes into a neural crest-like state as a single factor. MSX1-reprogrammed melanocytes lose pigmentation and become multipotent. To identify immediate targets of MSX1, we generated a tetracycline-inducible system (Tet-ON) in order to express MSX1 in primary melanocytes (iMSX1) in a clean and rapid way starting at defined time points and perform a global gene expression analysis.

LM resistance

Project description:The combination therapy of the Artemisinin-derivative Artemether (ART) with Lumefantrine (LM) (Coartem®) is an important malaria treatment regimen in many endemic countries. Resistance to Artemisinin has already been reported, and it is feared that LM resistance (LMR) could also evolve quickly. Therefore molecular markers which can be used to track Coartem®efficacy are urgently needed. Often, stable resistance arises from initial, unstable phenotypes that can be identified in vitro. Here we have used the Plasmodium falciparum multidrug resistant reference strain V1S to induce LMR in vitro by culturing the parasite under continuous drug pressure for 16 months. The initial IC50 (inhibitory concentration that kills 50% of the parasite population) was 24 nM. The resulting resistant strain V1SLM, obtained after culture for an estimated 166 cycles under LM pressure, grew steadily in 378 nM of LM; this corresponds to 15 times the IC50 of the parental strain. However, after two weeks of culturing V1SLM in drug-free medium, the IC50 returned to that of the initial, parental strain V1S. This transient drug tolerance was associated with major changes in gene expression profiles: when we explored V1SLM using the PFSANGER Affymetrix custom array, we identified 184 differentially expressed (DE) genes; amongst those 18 putative transporters including the multidrug resistance gene (pfmdr1), the multidrug resistance associated protein (pfmrp1) and the V-type H+ pumping pyrophosphatase 2 (pfvp2). Moreover, our results showed significant enrichment of genes associated with fatty acid metabolism and a clear selective advantage for two genomic loci in parasites grown under LM drug pressure, suggesting these genes may contribute to LM response in P. falciparum and could prove useful as molecular markers to monitor LM susceptibility.

Msx1 ChIP-Seq from C2C12 murine myoblast cells expressing Flag-Msx1 protein

Project description:The spatial and temporal control of gene expression during development requires the concerted actions of sequence-specific transcriptional regulators and epigenetic chromatin modifiers, which are thought to function within precise nuclear compartments. However, how these activities are coordinated within the dynamic context of the nuclear environment is still largely unresolved. Here we show that transcriptional repression by the Msx1 homeoprotein coordinates recruitment of Polycomb to genomic targets with localization to the nuclear periphery. We used genome-wide ChIP-Seq analyses to identify genomic binding sites for Msx1 in C2C12 murine myoblast cells.

Analysis of the MSX1 downstream signaling network in neuroblastoma

Project description:Neuroblastoma is an embryonal tumour of the peripheral sympathetic nervous system (SNS). One of the master regulator genes for peripheral SNS differentiation, the homeobox transcription factor PHOX2B, is mutated in familiar and sporadic neuroblastomas. Here we report that inducible expression of PHOX2B in the neuroblastoma cell line SJNB-8 down-regulates MSX1, a homeobox gene important for embryonic neural crest development. Inducible expression of MSX1 in SJNB-8 caused inhibition of both cell proliferation and colony formation in soft agar. Affymetrix micro- array and Northern blot analysis demonstrated that MSX1 strongly up-regulated the Delta-Notch pathway. These experiments describe for the first time regulation of the Delta-Notch pathway by MSX1, and connect these genes to the PHOX2B oncogene, indicative of a role in neuroblastoma biology. Keywords: Delta, Notch, MSX1, neuroblastoma, PHOX2B
