Project description:Here we provide mass-spectrometry based plasma proteomics data of hibernating and active wild Scandinavian brown bears (Ursus arctos arctos). The brown bear hibernates for half the year. Despite obesity and the prolonged period of inactivity, bears show no signs of the harmful effects associated with these conditions in humans. Thus, the hibernating bear is a protentional translational model for addressing these complications in humans. We analyzed plasma samples from 14 subadult 2- to 3-year-old (y/o) bears (6 males and 8 females) collected both during hibernation and active state, and for some for the bears during two seasons, resulting in a total of 38 analyzed plasma samples. In triplicates, the proteins in the plasma samples were unfolded and reduced. To increase depth of the analysis and the chance to detect low molecular weight proteins and peptides, we filtered samples with a 50K MWCO filter with the aim to deplete larger proteins. The proteins in the permeate were then tryptically digested, desalted, and analyzed with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Protein identification and quantification was performed with the MaxQuant software searching against an Ursus arctos horribilis protein database.

Project description:The detection of dairy processing is pivotal to our understanding of ancient subsistence strategies. This culinary process is linked to key arguments surrounding the evolution of lactase persistence in prehistory. Despite extensive evidence indicating the presence of dairy products in ceramics in the European Neolithic, questions remain about the nature and extent of milk (and lactose) processing and consumption. In order to investigate past patterns of dairy processing, here we analyse ancient proteins identified from Late Neolithic Funnel Beaker ceramics, scrutinising the principle that curd and whey proteins partition during the production of dairy foods from milk. Our results indicate the presence of casein-rich dairy products in these vessels suggesting the creation of curd-enriched products from raw milk. Moreover, this analysis reveals the use of multiple species for their dairy products in the Late Neolithic Funnel Beaker culture, adding to a growing body of evidence that multiple taxa were exploited for dairying in the Neolithic. Alongside palaeoproteomic analysis we also apply lipid residue analysis, with discrepancies in these two approaches suggesting that effects from isotope mixing may be underestimating the frequency of milk use in prehistoric pottery, highlighting the utility of a multi-stranded approach.

Project description:Periodontal pathogens (Porphyromonas gingivalis, Fusobacterium nucleatum) are known as one of several important bacterial pathogens associated with sporadic Alzheimer's disease (AD). It is suggested that the entry of Periodontal pathogens into the brain is due to the disruption of the tight junctions of endothelial cells by Periodontal pathogens. However, genomic alterations that occur as a result of Periodontal pathogens infection in endothelial cells are not well understood. Our goal was to identify genes associated with Periodontal pathogens infection-induced endothelial dysfunction by integrating gene expression data.
