Characterization of miRNAs modulated by torpor in the hibernating ground squirrel Ictidomys tridecemlineatus liver by next-generation sequencing.
Bibliographic record
Abstract
BACKGROUND: Mammalian hibernation is a fascinating phenomenon that involves multiple molecular and biochemical changes to proceed. While the molecular picture associated with torpor has become clearer in recent years, the function of non-coding RNAs, and especially of microRNAs, solicited during this process is not well understood. OBJECTIVE: To better characterize a signature of cold torpor-associated miRNAs in the hibernating thirteen-lined ground squirrel Ictidomys tridecemlineatus. MATERIALS AND METHODS: Next-generation sequencing and qRT-PCR approaches were conducted in euthermic and hibernating ground squirrel liver tissues. RESULTS: This high-throughput approach notably revealed modulation during hibernation of various miRNAs previously associated with lipid metabolism, glucose metabolism and antioxidant responses such as miR-145a-3p, miR-22-3p and miR-25-3p, respectively. CONCLUSION: Overall, these results present a group of miRNAs differentially expressed in hibernating ground squirrel liver and provide additional knowledge on the underlying functions of these small non-coding molecules during cold torpor.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
