Label-free quantitative proteomic analysis of the oral bacteria Fusobacterium nucleatum and Porphyromonas gingivalis to identify protein features relevant in biofilm formation. Anaerobe.

  Background The opportunistic pathogens Fusobacterium nucleatum and Porphyromonas gingivalis are Gram-negative bacteria associated with oral biofilm and periodontal disease. This study investigated interactions between F. nucleatum and P. gingivalis proteomes with the objective to identify proteins relevant in biofilm formation. Methods We applied liquid chromatography-tandem mass spectrometry to determine the expressed proteome of F. nucleatum and P. gingivalis cells grown in biofilm or planktonic culture, and as mono- and dual-species models. The detected proteins were classified into functional categories and their label-free quantitative (LFQ) intensities statistically compared. Results The proteomic analyses detected 1,322 F. nucleatum and 966 P. gingivalis proteins, including abundant virulence factors. Using univariate statistics, we identified significant changes between biofilm and planktonic culture (p-value ≤0.05) in 0,4% F. nucleatum, 7% P. gingivalis, and 14% of all proteins in the dual-species model. For both species, proteins involved in vitamin B2 (riboflavin) metabolism had significantly increased levels in biofilm. In both mono- and dual-species biofilms, P. gingivalis increased the production of proteins for translation, oxidation-reduction, and amino acid metabolism compared to planktonic cultures. However, when we compared LFQ intensities between mono- and dual-species, over 90% of the significantly changed P. gingivalis proteins had their levels reduced in biofilm and planktonic settings of the dual-species model. Conclusions The findings suggest that P. gingivalis reduces the production of multiple proteins because of the F. nucleatum presence. The results highlight the complex interactions of bacteria contributing to oral biofilms, which need to be considered in the design of prevention strategies.

  The Norwegian GBIF node in cooperation with the Arctic University Museum of Norway would like to welcome you to an open biodiversity data seminar on Thursday 23rd and Friday 24th of May in Tromsø at Tromsø Museum. On day one, we will present the GBIF along with interesting use cases demonstrating how this infrastructure can help make your biodiversity research transparent and reproducible. On day 2 we offer hands-on training with data publishing. This is a fantastic opportunity to work on your data with the assistance of experts. We invite you to bring your own data. It is also possible to practise with dummy data that we can provide for you. No experience is required, as long as you know and understand your own dataset!

  GBIF—the Global Biodiversity Information Facility—is an international network and data infrastructure funded by the world's governments and aimed at providing anyone, anywhere, open access to data about all types of life on Earth. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The workshop will demonstrate how you can access different types of biodiversity data published through the GBIF platform. And we will also have a brief "bring-your-own-data" workshop to demonstrate how you can publish your own research data to the GBIF platform and get a dataset DOI with data citation tracking services to follow what your dataset is reused for and by whom.

  Capacity building is an essential component of the GBIF community, a "soft" skill that (even with all the pandemic-related practice) is exceedingly hard to do well. Ahead of a summer calendar that includes the GBIF Global Nodes Meeting and the start of dozens of new projects funded through the BID, BIFA and CESP programmes, this session of the GBIF community webinar will take a deeper look into current training activities across the network.

  GBIF Norway (GBIF.no) and the Norwegian Biodiversity Information Centre (Artsdatabanken.no) organize a seminar on data publishing in Tromsø on 7th and 8th of September 2016. The seminar is suitable for all institutions, companies and other stakeholders that are engaged in registration of, or have plans to start registration of species-based biodiversity data. The seminar will cover the importance of collecting and publishing species-based biodiversity data, and describe some of the methods for data registration and data publication. Following the seminar on day 1 we will organize a training workshop where all participants will get basic skills for preparing and standardizing their own datasets. On day 2 we will be available for individual support with data publication. To sign up for day 2, you should already have datasets that are ready for publication. We plan to complete as far as possible the data preparation and data publication during the hands-on workshop.
