Molecular profiling of osteoprogenitor cells reveals FOS as a master regulator of bone non-union [timecourse]

Project description:Despite the advances in bone fracture treatment, a significant fraction of fracture patients will develop non-union. Most non-unions are treated with surgery since identifying the molecular causes of these defects is exceptionally challenging. In this study, compared with marrow bone, we generated a transcriptional atlas of human osteoprogenitor cells derived from healing callus and non-union fractures. Detailed comparison among the three conditions revealed a substantial similarity of callus and nonunion at the gene expression level. Nevertheless, when assayed functionally, they showed different osteogenic potential. Utilizing longitudinal transcriptional profiling of the osteoprogenitor cells, we identified FOS as a putative master regulator of non-union fractures. We validated FOS activity by profiling a validation cohort of 31 tissue samples. Our work identified new molecular targets for non-union classification and treatment while providing a valuable resource to better understand human bone healing biology.

Non-union skeletal fractures

Project description:Non-union skeletal fractures are characterized by their inability to heal six months after injury. Left untreated, the non-union fracture may cause advanced arthritis or loss of function in the affected limb. Arrays were used to identify the mechanisms that lead to lack of skeletal repair in non-unions. These profiles are the non-union callous samples pooled from five individuals Keywords: other

Transcriptional analysis for cell-cell communication during graft union development in Arabidopsis

Project description:Grafting is an ancient cloning method that has been used widely for thousands of years in agricultural practices. However, the molecular mechanisms for graft union development are still largely unknown. The developmental stage of graft union was characterized based on micrografting method. Microarray data revealed a signal exchange process between cells of scion and stock at 1dag, which reestablished the communication network in graft union. This process was concomitant with the cleaning of cell debris, and both of the processes were initiated by a wound-induced program. The results demonstrate the feasibility and potential power of investigating various plant developmental processes by this method and represent a primary and significant step in interpretation of the molecular mechanisms underlying graft union development.

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.
