- The publisher of the article Oxford University Press is apart of the University of Oxford and its purpose is to advance education and scientific research by publishing worldwide.
- Is this article available in print or online only?
- The article is available in both print and online
- Has LMU paid a subscription or other fee for your access to this article?
- No LMU has not paid a subscription for access to this article.
- Used the genome sequencing article to perform a prospective search in the ISI Web of Science/Knowledge database.
- Is this article available in print or online only?
- Overview of the search:
- How many articles does this article cite? 37
- How many articles cite this article? 303
- Based on the titles and abstracts of the papers, what type of research directions have been taken now that the genome for that organism has been sequenced?
- Now that the genome has been sequenced, a majority of research has been done on discovering which genes are responsible for virulence and pathogenesis as well as potential antibiotics. Genomic research is also focused on how S. flexneri has been able to develop resistance to multiple drugs. Furthermore, Shigella is suspected to have evolved from Escherichia coli so a lot of research has been done in how and when pathogenic Shigella split from E. coli on the evolutionary tree.
- Micro array data information
- This micro array data provides 6 biological replicates.
- The experiment performed is a competitive hybridization (also known as a "two-color" or "two-channel") experiment where one sample was labeled with the Cy3 dye and the other sample was labeled with the Cy5 dye (i.e., not an "Affymetrix" chip).
- The control sample is derived from mRNA and not genomic DNA.
- The database used to find the micro array was the NCBI Gene Expression Omnibus
- We used the specific species of shigella flexneri 2a.
- Overview of search results
- Number of Results:
- 5 results appeared
- Relevant results:
- There were 2, possibly 3, relevant results.
- http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE12535
- Experiment performed with "treatment" and "control" explanation:
- A virulence Plasmid cured Shigella flexneri and a wild type shigella flexneri 2a were both observed to see protein expression at 30°C and 37°C. The control would be the Wild type shigella flexneri 2a, and the treatment is the change in temperatures.
- There were 12 biological replicates and 4 technical replicates of the experiment done.
- Number of Results:
Global analysis of a plasmid-cured Shigella flexneri strain: new insights into the interaction between the chromosome and a virulence plasmid.

- The publisher is a sceintific society. The Journal of Proteome Research publishes content encompassing all aspects of global protein analysis and function, including the dynamic aspects of genomics, spatio-temporal proteomics, metabonomics and metabolomics, clinical and agricultural proteomics, as well as advances in methodology including bioinformatics. The theme and emphasis is on a multidisciplinary approach to the life sciences through the synergy between the different types of "omics". -quote from the about section http://pubs.acs.org/page/jprobs/about.html
- Used the ISI Web of Science/Knowledge database to search this article
- The article has 28 cited references
- The article is cited 4 times
- Directions of research has been focused towards profiling which parts of the shigella flexneri genome is responsible for virulence and pathogenicity factors along with chromosomal inactivation.
- Global patterns of gene expression of a virulence cured plasmid strain compared with the wild-type strain were analyzed using 2-DE combined with MALDI-TOF MS.
- There are 6 biological replicates total.
- The control sample is derived from mRNA
- Overview of Search Results
- The results of the search mainly consisted of E.coli and Shigella flexneri transcriptional profiling.
- There are 178 results in the GEO DataSets Database and 22283 in GEO profiles database.
- The results were mostly relevant, the first results were datasets. Anything related to the bacteria came up, the order was seemingly relevant.
- The micro array data can be found http://pubs.acs.org/doi/abs/10.1021/pr9007514
- The experiment was contrasting the pathegenicity of a virulence cured plasmid strain versus a wild type shigella flexneri, a virulence plasmid cured strain was constructed through plasmid incompatibility. The control was the wild type Shigella flexneri strain in each experimental construct.
- There were at least 3 biological replicates of each experiment conducted and 2 techincal replicates.
