<scp>JMJD</scp>2B/<scp>KDM</scp>4B inactivation in adipose tissues accelerates obesity and systemic metabolic abnormalities
Bibliographic record
Abstract
Obesity is a serious global health issue; however, the roles of genetics and epigenetics in the onset and progression of obesity are still not completely understood. The aim of this study was to determine the role of Kdm4b, which belongs to a subfamily of histone demethylases, in adipogenesis and fat metabolism in vivo. We established conditional Kdm4b knockout mice. Inactivation of Kdm4b in adipocytes (K4bKO) induced profound obesity in mice on a high fat diet (HFD). The HFD-fed K4bKO mice exhibited an increased volume of fat mass and higher expression levels of adipogenesis-related genes. In contrast, the genes involved in energy expenditure and mitochondrial functions were down-regulated. Supporting these findings, the energy expenditure of Kdm4b-deficient cells was markedly decreased. In addition, progression of glucose intolerance and hepatic steatosis with hepatocellular damages was observed. These data indicate that Kdm4b is a critical regulator of systemic metabolism via enhancing energy expenditure in adipocytes.

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.
