Abstract 68: The WWOX Gene Modulates HDL Metabolism and Lipoprotein Gene Expression
Bibliographic record
Abstract
Low plasma HDL cholesterol (HDL-C) constitutes a major risk factor for coronary artery disease. We previously identified a region-wide association between low HDL-C and the WW domain-containing oxidoreductase ( WWOX ) gene in dyslipidemic families and low HDL-C cases and controls (rs2548861, P=6.9x10 -7 ). Here, through a combination of in vivo functional studies, gene microarray and next generation resequencing, we investigated the role of WWOX in lipoprotein and HDL metabolism. Using total Wwox -/- and Wwox liver-specific ( hep -/- ) mice, we found decreased apoA-I and ABCA1 protein levels in hepatic tissues. Analyses of lipoprotein profiles in Wwox -/- littermates also showed marked reductions in serum HDL-C and apoA-I levels, with no effect in Wwox hep -/- mice. A sex-specific difference was however observed in female Wwox hep -/- mice, showing a significant increase in plasma triglycerides levels. We further obtained evidence of a gender-specific effect by gene microarray analyses in Wwox hep -/- hepatocytes, where it was identified that WWOX disruption alters primarily lipid metabolic pathways in females. We observed a significant reduction (P<0.05,

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.
