Expanding the genetic tool kit helps dissect a global stress response in the early-branching species Fusobacterium nucleatum

ABSTRACT: We elucidated the global regulatory network of sigma E in Fusobacterium nucleatum. For this, we developed new genetic tools for the anaerobic bacterium. This uncovered a conserved regulon of the sigma factor including a noncoding arm of the sRNA FoxI. In this process, FoxI serves as a negative regulator of sigma E to downregulate several outer membrane proteins as well as the putative galactose transporter mglBAC.

Comparison of Fusobacterium Nucleatum stimulated and unstimulated neutrophils

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

The effect of blood on Fusobacterium nucleatum

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.

Fusobacterium nucleatum promotes colorectal cancer metastasis through miR-1322/CCL20 axis and M2 polarization

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.

RNA-seq of PBT2-Zn treated Fusobacterium nucleatum cells in vitro

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.
