FOS Guards Quiescence and Potency in Human Hematopoietic Stem Cells [scRNA-seq]

Project description:Quiescence and limited dividing are critical in preserving potency of hematopoietic stem/progenitor cell (HSPCs) during lifetime, but little is known about how this process is regulated. Here, we show that the mobilized human HSPCs in peripheral blood (PB) are predominantly in a quiescent state, but rapidly exit quiescence and reduce repopulating potency in short-term culture. Through single cell RNA-seq, we identified a panel of regulators highly associated with HSC quiescence exit and cell-cycle entry. These regulators involve different biological processes such as cell-cycle, signaling pathways, metabolisms, etc. Among them, the oncogene, FOS restrains cell-cycle entry and supports repopulating potency in human HSCs through directly binding and regulating genes both for HSC quiescence and potency. Our findings uncover the regulatory program underlying quiescence exit and highlight the critical role of FOS to guard the quiescence and potency in human HSPCs.

Tubastatin A maintains skeletal muscle stem cell (MuSC) quiescence

Project description:We show that Tubastatin A (TubA) preserves MuSC quiescence and stem cell potency ex vivo, by inhibiting HDAC6 and, consequently, primary cilium resorption. Treatment with TubA improves MuSC engraftment potential and induces a return to quiescence in cycling MuSCs, revealing a potentially valuable approach to enhancing the therapeutic potential of MuSCs. To examine the state of quiescence preserved by TubA at the transcriptome level, we performed RNA-Seq and we found that TubA-treated MuSCs exhibit a quiescent transcriptome. The molecular mechanisms involved in the maintenance of quiescence by TubA were ribosome- and oxidative phosphorylation-related genes as well as low expression levels of cell cycle genes and Hh signaling genes.

The Aryl hydrocarbon receptor and FOS mediated cytotoxicity induced by Acenatobacter baumannii

Project description:Acinetobacter baumannii is a highly pathogenic and multidrug-resistant Gram-negative bacterium that causes severe nosocomial infections. To better understand the mechanism of pathogenesis, we compare the proteomes of uninfected and infected human cells, revealing that transcription factor FOS is the host protein most strongly induced by A. baumannii infection. Pharmacological inhibition of FOS reduces the cytotoxicity of A. baumannii in cell-based models, and similar results are also observed in a mouse infection model. A. baumannii outer membrane vesicles (OMVs) are shown to activate the aryl hydrocarbon receptor (AHR) of host cells by inducing the host enzyme tryptophan-2,3-dioxygenase (TDO), producing the ligand kynurenine, which binds AHR. Following ligand binding, AHR is a direct transcriptional activator of the FOS gene. Our results suggest that bacterial infection interacts with host tryptophan metabolism and the transcription factor FOS.
