Project description:Fusobacterium nucleatum is a Gram-negative oral bacterial species associated with periodontal disease progression. As periodontal disease progresses, it is known F. nucleatum coaggregated with blood is frequently detected in the gingival crevice. However, it is largely unknown whether these interactions between F. nucleatum and blood induce a particular genetic response. We tested the cultures of F. nucleatum ATCC 25586 with or without blood in a semi-defined growth medium by microarray analysis and found 14 genes that were affected after only about 4hr. of adhered blood. Then, we selected 7 genes that changed significantly and tested these genes via real-time RT-PCR to confirm the validity of the microarray results. As a result, one amino sugar-binding protein on the membrane of F. nucleatum was especially expressed high via both microarray and real-time RT-PCR. Based upon these data, it appears that the protein on the F. nucleatum membrane binds and transfers the amino sugar only under blood conditions. This study aims to determine the effect of blood on the gene expression profiling of F. nucreatum. The study contains 2 separate experiments that both measure the cultures without or with blood. The samples with blood contain 9% and 33% blood.

Project description:Localization of Fusobacterium nucleatum in the placenta may be associated with pregnancy complications including preeclampsia (PE), but its specific pathobiology is unknown. Our aim was to analyze the effect of Fusobacterium nucleatum on HUVEC cells to further elucidate placental dysfunction in the context of Fusobacterium nucleatum infestation.

Project description:Neutrophils are known to be stimulated by different periodontal bacteria to produce reactive oxygen species and cytokines. It is inportant to investigate the gene changes made by bacteria of importance, of which, for periodontal disease, fusobaterium nucleatum is one. we used microarrays to investigate gene experssion changes in peripheral blood neutrophils werwhich e stimulated with or with out Fusobacterium Nucleatum (10953). Neutrophils from periodonatlly healthy individuals (n=4) were isolated and stimulated for 3hrs with or without fusobaterium nucleatum (10953). RNA was then extracted from these and pooled before hybridization on Affymetrix microarrays

Project description:Fusobacterium nucleatum-treated LoVo cells reported an increased promoting CRC metastasis effect compared with PBS control. To understand the underlying mechanisms of Fusobacterium nucleatum-induced metastasis ability of CRC cells, we performed RNA-sequencing in LoVo cells s with or without Fusobacterium nucleatum treatment with three independent biological replicates.

Project description:To investigate the effect of the Zn ionophore, PBT2, on the transcriptomic response of Fusobacterium nucleatum ATCC 25586, RNA was extracted from bacterial samples which had been treated as follows: Untreated (0.006% DMSO v/v), DMSO-Zn treated (0.006% DMSO v/v + 200 uM ZnSO4), or PBT2-Zn treated (0.125 ug/mL PBT2 + 200 uM ZnSO4) (DMSO was the vehicle control). RNA samples were collected at 0h, 0.5h, and 1h post challenge in biological triplicate and sequenced using Illumina HiSeq platform. We mapped sequences to the reference genome F. nucleatum subsp. nucleatum ATCC 25586 and performed DEseq2 analysis to determine differentially expressed genes across time and treatment.

Project description:Fusobacterium nucleatum is a Gram-negative anaerobic bacteria that is commonly found in oral cavities and is associated with connective tissue destruction in periodontitis. UDP-N-acetylglucosamine 1-carboxyltransferase with enzyme commission number 2.5.1.7 is a transferases enzyme that plays a role in bacterial pathogenesis. Inhibiting binding sites of UDP-N-acetylglucosamine 1-carboxyltransferase is needed to find potential antibiotic candidates for periodontitis treatment. Hence, the research aimed to present potential UDP-N-acetylglucosamine 1-carboxyltransferase inhibiting compounds through molecular docking simulation by in silico analysis. DrugBank database was used to obtain the antibacterial candidates, which were further screened computationally using the AutoDock Vina program on Google Colab Pro. The top nine compounds yielded binding affinity ranging from -12.1 to -12.8 kcal/mol, with conivaptan as one of the three compounds having the highest binding affinity. Molecular dynamic study revealed that the ligand-protein complex for conivaptan had root-mean-square deviation values of 0.05-1.1 nm, indicating likeliness for stable interaction. Our findings suggest that conivaptan is the potent UDP-N-acetylglucosamine 1-carboxyltransferase inhibitor, hence its efficacy against periodontitis-causing bacteria.
