Colony Stimulating Factor 1(CSF1) is known to promote osteoclast progenitor survival but its role in regulating osteoclast differentiation and mature osteoclast function are less well understood.
The transcription factor T-box 3 regulates colony-stimulating factor 1-dependent Jun dimerization protein 2 expression and plays an important role in osteoclastogenesis.

View SamplesInduced pluripotent stem cells (iPSCs) can be derived from somatic cells through ectopic expression of transcriptional factors or chemical cocktails. Chemical reprogramming might be safe than transcriptional factors since there is no integration of exogenous genes. However, there is still little direct evidence to prove this hypothesis. In this study, we have performed whole genome profiling of the DNA methylomes of mouse chemical iPSCs (CiPSCs), transcriptional factors induced iPSCs (TF-iPSCs) and embryonic stem cells (ESCs). We find that the methylation levels of high-CpG-density promoters (HCPs) and intermediate- CpG-density promoters (ICPs) have no significant difference among them, but low-CpG-density promoters (LCP) and three retrotransposons (LINEs, LTRs and SINEs) show preference to different methylation levels. Surprisingly, CiPSCs are hypomethylated than TF-iPSCs and the major difference of methylation levels lies in the intergenic regions while two iPSCs lines are generally hypermethylated compared to ESCs. Moveover, we find the methylation states of imprinting control regions (ICRs) and the expression of imprinted genes of CiPSCs are more resemble ESCs than TF-iPSCs. Our data first provide the epigenetic states of chemical induced pluripotent stem cells and compare the difference of mouse CiPSCs, TF-iPSCs and ESCs. These observations might affect ongoing choices of reprogramming methods for disease modeling and give some guides for potential therapeutic applications. Overall design: Comparison of DNA methylation and genes expression patterns in 3 cell types
Genome-wide DNA methylation analysis reveals that mouse chemical iPSCs have closer epigenetic features to mESCs than OSKM-integrated iPSCs.

View SamplesSND1 protein is a highly conserved protein of eukaryotic cells and is involved in a group of cellular biological processes, such as gene transcription, pre-mRNA splicing, cell cycle, DNA damage repair, proliferation and programmed cell death degradome, adipogenesis and cancerogenesis. SND1 can promote the metastasis and proliferation of breast cancer cells by down-regulating the miR-127 expression.
SND1 acts as an anti-apoptotic factor via regulating the expression of lncRNA UCA1 in hepatocellular carcinoma.

View SamplesRNA-binding proteins (RBPs) are involved in a wide variety of regulatory pathways in mammalian cells. Here, we report that the DEAD-box RBP DDX5 (also known as p68) inhibits induced pluripotency by negatively regulating the expression and function of a non-canonical polycomb complex 1 (PRC1) subunit, RYBP, by modulating microRNA-125b processing. DDX5 loss-of-function, both during reprogramming and the somatic to pluripotent transition, and also in the differentiation of mouse embryonic stem cells, results in the suppression of lineage-specific genes via an RYBP-dependent ubiquitination of histone H2A at K119 (H2AK119ub1). RYBP functions as both transcriptional repressor through PRC1 but also as an activator through its interaction with OCT4 during reprogramming. Diminished DDX5 also potentiates RYBP-mediated recruitment of OCT4 to the promoter of the pluripotency activation gene Kdm2b. These data show that DDX5 down-regulation stimulates silencing of lineage-specific genes by RYBP-PRC1 in the early phase of reprogramming and activation of the pluripotency gene network by RYBP-OCT4 in the later phase of reprogramming. Overall design: RNA-seq profiles of wild type (WT) and knockout DDX5-/- (also known as p68) mouse ESCs were generated by deep sequencing, Samples were sequenced in triplicate.

View SamplesThe main goal of our study is to identify the molecular events that determine the gonadal identity in mammals. Although testis and ovary arise from a common embryonic primordium, they represent outcomes of opposing fate determination. This decision to differentiate into a testis or an ovary hinges upon the balance between two antagonizing factors, pro-testis SOX9 and pro-ovary -catenin.
