  1. Hibernation is a fascinating adaptation to food-scarce winters, characterized by significant physiological and behavioral changes, including fasting, inactivity, and insulin resistance. While hibernation is critical for the survival of many species, hibernation-related traits are often considered pathological in humans. Hibernation has been studied from a genomic perspective, especially with respect to transcription across multiple tissues. These studies have identified the differential activity of signaling pathways related to metabolism, tissue protection, and other mechanisms likely underlying hibernation phenotypes. Bears, in particular, are an interesting model for physiological and genomic studies of hibernation due to their large size and unique mode of hibernation compared to other small mammalian hibernators. Investigating the intricate molecular mechanisms underlying bear hibernation may therefore provide insight into fundamental biological processes with potential translational implications for human health, particularly with respect to metabolic disorders such as type II diabetes. This review focuses on recent advances and outstanding questions related to the exploration of bear hibernation from a genomic perspective.
