Intestinal Resection- and Steroid-Associated Alterations in Gene Expression Were Not Accompanied by Changes in Lipid Uptake
Bibliographic record
Abstract
BACKGROUND/AIMS: Glucocorticosteroids alter the morphology and transport function of the intestine of adult rats. This study was undertaken to assess the possible effect on intestinal lipid uptake of the locally acting steroid budesonide, or the systemically active prednisone or dexamethasone. METHODS: Sprague-Dawley rats underwent intestinal transection or 50% intestinal resection. Budesonide, prednisone, dexamethasone, or control vehicle was given for 2 weeks from the time of surgery. Uptake was measured using ring uptake technique. RESULTS: Resection had no effect on the mRNA expression for the early response genes, for proglucagon, or for the ileal lipid binding protein (ILBP), but was associated with reduced jejunal ornithine decarboxylase (ODC) mRNA and with reduced jejunal mRNA for the liver fatty acid binding protein (L-FABP). All three steroids reduced jejunal mRNA for proglucagon and c-jun, and did not affect the mRNA for L-FABP or for ILBP. These resection- and steroid-associated changes in gene expression were not associated with alterations in the intestinal uptake of long chain fatty acids or cholesterol. CONCLUSIONS: The resection-associated alterations in the RNA expression of ODC and L-FABP and the steroid-associated changes in mRNA expression of c-jun and proglucagon were not accompanied by variations in lipid uptake.

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.
