Project description:Both FGF and WNT pathways play important roles in embryonic development, stem cell self-renewal and are frequently deregulated in breast cancer. To study the cooperation between FGF and WNT signaling, we have generated a mouse model, MMTV-WNT1/MMTV-iFGFR1 (WNT/iR1), in which we could chemically overactivate iFGFR1 in a ligand-independent manner.

Project description:Pancreatic cancer (PC) remains one of the most aggressive and life-threatening malignancies known for its notorious resistance to chemotherapy. This is increasingly ascribed to the subpopulation of undifferentiated cells, known as pancreatic cancer stem cells (PCSCs), which are evolutionary fitter than other tumor cells to evade the cytotoxic effects of chemotherapy. Those cells are crucial for tumor relapse as they possess ‘stem cell-like’ features of self-renewal and differentiation. However, what molecular mechanisms maintain the unique characteristics of PCSCs are poorly understood. Here, we identified an RNA polymerase II-associated PHF5A-PHF14-HMG20A-RAI1-KMT2A transcriptional subcomplex, which regulates the stemness characteristics and tumorigenicity of PCSCs through epigenetic control of gene expression. Targeting the protein subcomplex with a KMT2A-WDR5 inhibitor attenuated the self-renewal and in vivo tumorigenicity of PCSCs, thus offering a novel anti-PCSCs targeting strategy for enhancing the efficiency of chemotherapy which is likely to translate into durable clinical responses in PC patients.

Project description:The spermatogonial stem cells (SSCs) niche is critical for SSC maintenance and the subsequent spermatogenesis. Numerous reproductive hazards impair the SSC niche, thereby result in aberrant SSC self-renewal and male infertility. However, promising agents targeting the impaired SSC niche to promote SSC self-renewal are still limited. Here, we screen out and assess the effects of Lovastatin on the self-renewal of mouse spermatogonial stem cells (mSSCs). Mechanistically, Lovastatin promotes the self-renewal of mSSCs and inhibits its inflammation and apoptosis through the regulation of isoprenoid intermediates. Likewise, other statins exhibit similar effects on SSC self-renewal. Remarkably, the treatment by Lovastatin could promote the self-renewal of mSSCs in the male gonadotoxicity model generated by busulfan injection. Noteworthy, we demonstrate that Lovastatin could significantly enhance the self-renewal of in vitro cultured primate SSCs. Collectively, our findings uncover that lovastatin could promote the self-renewal of both murine and primate SSCs and have implications for the treatment of certain male infertility using small compounds.

Project description:Chickarmane2006 - Stem cell switch reversible
Kinetic modeling approach of the transcriptional dynamics of the embryonic stem cell switch.
This model is described in the article:
Transcriptional dynamics of the embryonic stem cell switch.
Chickarmane V, Troein C, Nuber UA, Sauro HM, Peterson C
PLoS Computational Biology. 2006; 2(9):e123
Abstract:
Recent ChIP experiments of human and mouse embryonic stem cells have elucidated the architecture of the transcriptional regulatory circuitry responsible for cell determination, which involves the transcription factors OCT4, SOX2, and NANOG. In addition to regulating each other through feedback loops, these genes also regulate downstream target genes involved in the maintenance and differentiation of embryonic stem cells. A search for the OCT4-SOX2-NANOG network motif in other species reveals that it is unique to mammals. With a kinetic modeling approach, we ascribe function to the observed OCT4-SOX2-NANOG network by making plausible assumptions about the interactions between the transcription factors at the gene promoter binding sites and RNA polymerase (RNAP), at each of the three genes as well as at the target genes. We identify a bistable switch in the network, which arises due to several positive feedback loops, and is switched on/off by input environmental signals. The switch stabilizes the expression levels of the three genes, and through their regulatory roles on the downstream target genes, leads to a binary decision: when OCT4, SOX2, and NANOG are expressed and the switch is on, the self-renewal genes are on and the differentiation genes are off. The opposite holds when the switch is off. The model is extremely robust to parameter changes. In addition to providing a self-consistent picture of the transcriptional circuit, the model generates several predictions. Increasing the binding strength of NANOG to OCT4 and SOX2, or increasing its basal transcriptional rate, leads to an irreversible bistable switch: the switch remains on even when the activating signal is removed. Hence, the stem cell can be manipulated to be self-renewing without the requirement of input signals. We also suggest tests that could discriminate between a variety of feedforward regulation architectures of the target genes by OCT4, SOX2, and NANOG.

Project description:Activin/Nodal/TGF-β signaling pathway plays a major role in maintaining mouse epiblast stem cells (mEpiSCs). The mEpiSC medium which contains Activin A and bFGF induces differentiation of mouse embryonic stem cells (mESCs) to mEpiSC. Here we show that Activin A also has an ability to efficiently propagate mESCs without differentiation to mEpiSCs when combined with a MEK inhibitor PD0325901. mESCs cultured in Activin+PD retained high-level expression of naive pluripotency-related transcription factors. Genome-wide analysis revealed that the gene expression profile of mESCs cultured in Activin+PD resembles that of mESCs cultured in 2i. mESCs cultured in Activin+PD also showed features which are related to naive pluripotency of mESCs, including the preferential usage of the Oct4 distal enhancer and the self-renewal response to Wnt pathway activation. Our finding reveals a role of Activin/Nodal/TGF-β signaling in stabilizing self-renewal gene regulatory networks in mESCs. To compare the gene expression patterns of mESCs cultured in Activin+PD, 2i and LIF+BMP4 and mEpiSCs, we performed genome-wide gene expression analysis by using Affymetrix GeneChip oligonucleotide microarrays
