Proteomic Analysis of Subchronic Furan Exposure in the Liver of Male Fischer F344 Rats
Bibliographic record
Abstract
344 rats exposed to various doses by gavage to determine the NOAEL. Previous reports have outlined changes in the liver using gross necropsy examination, histopathology, clinical biochemistry, hematology, immunohistochemistry, and toxicogenomics. The data revealed that males were more sensitive than females. The focus of this study was to evaluate the toxicoproteomic changes by 2-dimensional differential in gel electrophoresis followed by mass spectrometry analysis. To compliment previous studies, protein expression changes were evaluated of male animals after 90 days of exposure to doses of 0, 0.03, 0.5, and 8.0 mg/kg bw/d. Significant statistical treatment-related changes compared to the controls identified 45 protein spots containing 38 unique proteins. Proteins identified are implicated in metabolism, redox regulation, protein folding/proteolysis as well as structural and transport proteins. At lower doses, multiple cytoprotective pathways are activated to maintain a homeostasis but ultimately the loss of protein function and impairment of several pathways could lead to adverse health effects at higher doses of furan administration.

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.
