Title	Plasma proteomics data of hibernating and active wild Scandinavian brown bears
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.
