Effect of high-density lipoprotein associated cyclosporine on hepatic metabolism and renal function.
Bibliographic record
Abstract
Cyclosporine (CSA), in both humans and animals, is associated with plasma lipoproteins. It has been demonstrated that CSA-lipoprotein association is partly responsible for the distribution and toxicity related to CSA use. Altered plasma lipoprotein profiles are often seen in transplantation recipients undergoing CSA treatment. In the present study, daily 0.1 mg/kg intravenous injections of either high-density lipoprotein-associated CSA (HDL-CSA), plasma-associated CSA (Plasma-CSA), or CSA in Cremophor (CSA) were administered to adult male rats for 14 days. Vehicle controls included daily administrations of 0.5 ml/kg of Cremophor or saline. Serum creatinine levels, a marker of renal function, increased in rats administered Plasma-CSA as compared with control rats treated with CSA. CYP3A and CYP2C11 protein expression was suppressed by 27% and 39%, respectively, in the HDL-CSA treatment group and by 38% and 40% in the Plasma-CSA treated group as compared with CSA controls. In addition, 6beta-hydroxytestosterone, a marker of CYP3A activity, was reduced by 33% and 34% in the HDL-CSA and the Plasma-CSA treatment groups, respectively, as compared with the CSA control group. CYP2C11 activity was measured by the in vitro formation of 2alpha-hydroxytestosterone. Activity levels in rats treated with HDL-CSA and Plasma-CSA were slightly induced as compared to CSA controls, however these differences were not found to be statistically significant. In summary, Plasma-CSA treatment resulted in renal dysfunction and suppressed CYP3A and CPY2C11 protein expression. These results demonstratethat intravenous lipoprotein-associated CSA alters the metabolism of CSA in the rat differently than CSA alone.

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.
