In Vivo Knockdown of Adipocyte Erythropoietin Receptor Does Not Alter Glucose or Energy Homeostasis
Bibliographic record
Abstract
The growing prevalence of obesity and diabetes necessitate a better understanding of the role of adipocyte biology in metabolism. Increasingly, erythropoietin (EPO) has been shown to have extraerythropoietic and cytoprotective roles. Exogenous administration has recently been shown to have beneficial effects on obesity and diabetes in mouse models and EPO can modulate adipogenesis and insulin signaling in 3T3-L1 adipocytes. However, its physiological role in adipocytes has not been identified. Using male and female mice with adipose tissue-specific knockdown of the EPO receptor, we determine that adipocyte EPO signaling is not essential for the maintenance of energy homeostasis or glucose metabolism. Adipose tissue-specific disruption of EPO receptor did not alter adipose tissue expansion, adipocyte morphology, insulin resistance, inflammation, or angiogenesis in vivo. In contrast to the pharmacological effects of EPO, we demonstrate that EPO signaling at physiological levels is not essential for adipose tissue regulation of metabolism.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
