Next Generation Sequencing Facilitates Quantitative Analysis of the Role of Transcriptional Factor FoxM1 in Muscle Satellte Cells

ABSTRACT: Purpose:To identify genes and the molecular pathways involved in the transcriptional factor FoxM1 regulating muscle satellite cells (SCs) in mice, we performed RNA-Sequence of SCs in qiuescent state (homeostatic condition) or activated state (48 hours-post injury). Methods: mRNA profiles of SCs in FoxM1fl/fl (floxp) and FoxM1fl/fl,Pax7Cre/+ (cKO) in quiescent state (Qfloxp or QcKO) or activated state (Afloxp or AcKO) were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000. Activated state was induced by Bacl2 injection (48 hours-post injury). Results:Using an optimized data analysis workflow, we mapped about 9 million sequence reads per sample to the mouse genome (build mm10) and identified 13776 transcripts in SCs (the floxp and cKO group) with BWA workflow. Conclusions: Our results represent the first detailed analysis of SCs transcriptomes in FoxM1-knockout mice and found that FoxM1 regulated multiple mRNA pathways in SCs.

FoxM1 is essential for quiescence and maintenance of hematopoietic stem cell

Project description:FoxM1, a mammalian Forkhead Box M1 protein, is known as a typical proliferation-associated transcription factor that regulates of G1/S and G2/M transition in the proliferating cells. However, the in vivo function of FoxM1 in adult stem cells remains unknown. Here, we found that FoxM1 is highly expressed in hematopoietic stem cells (HSCs) and is essential for maintaining quiescence and self-renewal of HSCs in vivo. FoxM1-deficient mice developed leukopenia, thrombocytopenia and neutropenia with an approximately 6-fold decrease in HSC pool size, which is associated with a failure of G0 cell cycle regulation and increased cell cycling in HSCs. FoxM1 absence did not affect lineage commitment of HSCs and progenitors. However, FoxM1 loss significantly reduced the repopulating capacity and self-renewal of long-term HSC in a cell-autonomous manner. Mechanistically, FoxM1 loss markedly down-regulates the expression of orphan nuclear receptor Nurr1, known to regulate HSC quiescence. We found that FoxM1 directly bound the promoter region of Nurr1 and induced transcriptional activity of Nurr1 promoter in vitro, and forced expression of Nurr1 rescued FoxM1-deletion-induced G0 loss of HSC-enriched population in vitro. Thus, our studies show a previously unrecognized role of FoxM1 as a critical regulator of HSC quiescence and self-renewal by controlling Nurr1-mediated pathways. The Hematopoietic Stem Cells (HSCs) were sorted from FoxM1[fl/fl] and Tie2-Cre FoxM1[fl/fl] mice, then amplified with Ovation Pico WTA System V2 before microarray analysis. There are 3 samples from FoxM1[fl/fl]mice and 3 samples from Tie2-Cre FoxM1[fl/fl] mice.

Mouse Muscle Stem Cell Proteome during Activation and CPEB1 Dependent Proteome in Mouse Muscle Stem Cell

Project description:Muscle Stem Cells or satellite cells (SCs) are required for muscle regeneration. In resting muscles, SCs are kept in quiescence. After injury, SCs undergo rapid activation, proliferation and differentiation to repair damaged muscles. The transcriptome alteration during SC activation is well characterized. While transcriptome is not exactly represent proteome because of post-transcriptional regulations such as miRNA induced gene silencing. However, little is known about SC proteome. We obtained quisecent SCs (QSCs) and freshly isolated SCs (fiSCs, early activated SCs) and activated SCs (ASCs) for high resolution mass spectrometry Bruker timsTOF Pro. Thus, we uncovered the QSC proteome. By comparison of QSC proteome to fiuSCs proteome or ASCs proteome, we identified the pathways that are differentially expressed between them. Forthermore, we characterized a translational regulator CPEB1 reprogrammed translation landscape for SC activation.

Proteomic analysis of adult CNS from Rhoa cKOs and CTRs mice

Project description:Oligodendrocyte differentiation and subsequent myelination rely on strict regulatory mechanisms and molecules. Here we aimed at understanding the role of the Rho GTPase RhoA during oligodendrocyte differentiation and myelination in vivo. Using a conditional cell-specific ablation of Rhoa (Rhoa fl/fl mice crossed with Cnp-Cre mice) in oligodendrocytes, we show that RhoA controls the timing and progression differentiation and myelination. To identify putative mechanisms underlying the Rhoa cKO phenotype, we performed quantitative label-free LC-MS/MS proteomics on optic nerves from Rhoa cKO (Rhoa fl/fl Cre+) and control mice (Rhoa fl/fl Cre-) at 30 days post-birth (P30). Manual annotation of the differentially abundant proteins showed a large modulation of several proteins clusters associated with actin cytoskeleton, signal transduction and mitochondria.

Microarray analysis of U87 glioma cells after transient knockdown of FOXM1

Project description:FOXM1 plays a key role in M phase in normal cells and is overexpressed in human glioma. We found that FOXM1 deprivation could sensitize the glioma cells to TMZ chemotherapy. To find out the mechanistic regulation of FOXM1 in chemo-resistant genes, we used microarrays to select the potential genes regulated by FOXM1 which dominates in glioma chemo-resistance. U87 glioma cells were transiently transfected with none-target siRNA or FOXM1 siRNA. Total RNA were extracted after 48 hours and subjected to the microarray.
