Proteomics,MultiomicsProteomic and Transcriptomic Changes in Hibernating Grizzly Bears Reveal Metabolic and Signaling Pathways that Protect against Muscle Atrophy
Muscle atrophy is a physiological response to disuse and malnutrition, but hibernating bears are largely resistant to this phenomenon. Unlike other mammals, they efficiently reabsorb amino acids from urine, periodically activate muscle contraction, and their adipocytes differentially responds to ins...

TranscriptomicsGene Expression Data of Hibernating and Summer Active Black Bears
We conducted a large-scale gene expression screen using the 3,200 cDNA probe microarray developed specifically for Ursus americanus to detect expression differences in liver and skeletal muscle that occur during winter hibernation in comparison to animals sampled during summer. The expression of 12 ...

ProteomicsPlasma proteomics data of hibernating and active wild Scandinavian brown bears
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 wi...

TranscriptomicsModulation of gene expression in heart and liver of hibernating black bears (Ursus americanus)
We analyzed gene expression in the American black bear, Ursus americanus, using a custom 12,800 cDNA probe (BA02) microarray to detect differences in expression that occur in heart and liver during winter hibernation in comparison to summer active animals. We identified 245 genes in heart and 319 ge...

TranscriptomicsRNASeq analysis of brown bear (Ursus arctos) skin tissue during active state and hibernation
Transcriptomic analysis of the brown bear (Ursus arctos) tissues during both active and inactive phases has unveiled significant differential gene expression, with thousands of genes exhibiting altered activity in all studied tissues (muscle, liver, adipose...). Nevertheless, transcriptional analyse...
