RNA-seq Analysis of Msx2fl/fl(Msx2 WT) and Le-Cre+/- Msx2fl/fl(Msx2 CKO) Lens Transcriptomes

ABSTRACT: Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived lens transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: Lens RNA was extracted from Msx2 WT and Msx2 CKO mice at postnatal day 60 (P60) using RNAeasy™ Animal RNA Isolation Kit. The freshly frozen RNA solution was prepared for RNA sequencing on the same day. The RNA-seq was carried out using Illumina HiSeq sequencing (Novogene Bioinformatics Institute, Beijing, China). The insert size of the library was tested by Agilent 2100 Bioanalyzer to ensure library quality before Illumina HiSeq sequencing. The company used STAR software to compare RNA-seq sequencing data, HTSeq to analyze the quantitative of gene levels, RSEM to analyze transcript levels quantitatively, ClusterProfiler software to analyze differential gene enrichment, rMATS software to analyze alternative splicing, GATK software to analyze mutation sites and SnpEff software to analyze annotation of the variation sites. After mutation site detection and annotation, statistical analysis was done by Ts/Tv and Hom/Het, respectively. Results: RNA-sequencing results showed that 1,911 differentially expressed genes (DEGs) were detected. Among them, the expression of 1,586 genes were upregulated and the rest downregulated.

MSX2 safeguards syncytiotrophoblast fate of human TSCs

Project description:The majority of placental pathologies arise from failures in trophoblast differentiation, yet the underlying transcriptional regulation is poorly understood. Here, we use human trophoblast stem cells to elucidate the function of the transcription factor MSX2 in trophoblast specification. We show that depletion of MSX2 de-represses the syncytiotrophoblast program, while forced expression of MSX2 blocks it. We demonstrate that a large proportion of the affected genes are directly bound and regulated by MSX2 and identify components of the SWI/SNF complex as its strong interactors. Our findings uncover the pivotal role of MSX2 in cell fate decisions that govern human placental development and function.

The impact on reprogramming of Msx2

Project description:We report that we make the high-profiling for transcriptome to detect the impact on reprogramming of transcription factor Msx2 at different time points during reprogramming. Based on the technology of overexpression and Knock down for Msx2, we can observe the changes of transcriptomes in contrast with control group. We get the connections between Msx2 and BMP signaling, and other meaningful results, but we should make further validation.

Transcriptome profiling of isolated mammalian myotube cultures that ectopically overexpress msx2

Project description:In contrast to urodele amphibians and teleost fish, mammals lack the regenerative responses to replace large body parts. Amphibian and fish regeneration uses dedifferentiation, i.e. reversal of differentiated state, as a means to produce progenitor cells to eventually replace damaged tissues. Therefore, activation of dedifferentiation response in mammalian tissues holds an immense promise for human regenerative medicine. msx2 expression has been shown to peak at the early time points of amphibian limb regeneration. Despite this temporal importance in the heterogenous regenerating limb tissues, the potential role of msx2 in dedifferentiation was previously not addressed in salamander or mammalian muscle cells. In order to test this, we ectopically overexpressed msx2 in mammalian myotubes and profiled their transcriptomes using next generation sequencing. We identified 4964 up-regulated and 4464 down-regulated transcripts in myotubes compared to myoblasts (uninduced GFP control cells; ≥ 1.5 fold; FDR corrected p-values < 0.01). Upon ectopic msx2 expression in myotubes, 923 transcripts were downregulated, whereas 1283 transcripts were upregulated. Based on msx2’s potential role in dedifferentiation, we reasoned that the transcripts, which are normally upregulated in myotubes in comparison to myoblasts, should go down upon msx2-expression. In accord with this idea, 575 myotube-enriched transcripts were downregulated after one day of ectopic msx2 expression. Similarly, 331 myoblast-enriched transcripts were upregulated upon msx2 expression.

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.

RNAseq comparison of gene expression profiles in Hand2-Cre driven Msx1/Msx2 double conditional mutant and control mouse embryonic mandible

Project description:The mandible of the jawed vertebrate is derived from the mandibular process of the first pharyngeal arch of the early embryo. The first pharyngeal arch consists of cells from all three germ layers, with the neural crest giving rise to all the skeletal elements of the mandible. The correct patterning of the neural crest cells by spatially and temporally controlled expression of various transcription factors during mandible development is crucial for the proper morphogenesis of the lower jaw. Msx family genes encode transcription factors which contain the conserved homeodomain. Among the three members of Msx genes, Msx1 and Msx2 are expressed in the neural crest and epithelium of distal mandibular process during early embryonic development with partially overlapped expression patterns. Msx1-/- mouse embryos develop multiple craniofacial developmental defects including tooth agenesis, cleft palate, and hypoplastic mandible. Although no jaw defects were observed in Msx2-/- mouse embryos, Msx1-/-Msx2-/- mouse embryos exhibit significantly severer mandibular defects compared to Msx1-/- mouse embryos, suggesting a partial functional redundancy between the two genes in mandible development. Besides the direct roles of Msx1 and Msx2 in the development of the mandibular neural crest, the phenotypes of Msx1-/-Msx2-/- may also contributed by secondary impacts from defective pre-migrative neural crest and non-neural crest tissues. Here we performed the gene expression profiling by RNA-seq in the distal mandibular processes of Msx1f/f;Msx2f/f;Hand2-Cre and Msx1f/+;Msx2f/f;Hand2-Cre embryos at E10.75, the former developed distally truncated mandible at later stages while the latter served as morphologically normal littermate control. Comparing the gene expression profiles of the two will give us insight into the functions of Msx1 and Msx2 expressed in mandibular neural crest cells in the development of the mandible.
