Abstract 327: Cardiac Regulation of Metabolic Homeostasis by Med13
Bibliographic record
Abstract
Alterations in metabolism are a major component of cardiovascular disease associated with obesity and type 2 diabetes. The complex interplay between these three diseases poses a challenge for successful treatment and warrants further studies directed at understanding the intertissue communication between major metabolic organs. We previously identified a signaling pathway within the heart that modulates systemic energy homeostasis by regulation of Med13, a component of the kinase submodule of the Mediator Complex, in the heart. The Mediator Complex is a large, multiprotein complex that functions to integrate signal specific events with transcriptional activation and elongation in a context dependent manner. Our current work further delineates a mechanism by which Med13 in the heart functions to regulate whole body energy homeostasis. The increase in energy expenditure in Med13 transgenic (TG) mice is due in part to increased triglyceride uptake and beta-oxidation in white adipose tissue and liver. Additionally, the expression of Krebs Cycle and fatty acid oxidation genes are increased in adipose tissue and liver as measured by RNA seq and in metabolite production in Med13 Tg mice. Together, these results demonstrate the Mediator Complex regulates cardiac gene expression and metabolite production which communicates with energy depots within the body to modulate whole body energy homeostasis.

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.
