Identification of genes responsive to BPDE treatment in HeLa cells using cDNA expression assays
Bibliographic record
Abstract
Genotoxic stresses induce cellular responses that can be observed at the level of gene expression. We have studied changes in gene expression following BPDE exposure in HeLa cells by using a cDNA expression array of 597 human genes. After a 53-hr exposure to 0.4 microM BPDE, nine genes were upregulated. The protein products of these genes are: fos-related antigen 2, apoptotic cysteine protease MCH4, DB1 (zinc finger protein 91), transcription factor ETR103, integrin alpha, interleukin-4, interleukin-6, 23-kDa highly basic protein, and ribosomal protein S9. We observed the downregulation of gene expression of three genes: heat-shock protein 27, DNA-binding protein TAX, and NADH-ubiquinone oxidoreductase B18 subunit. These results suggest unknown functions or regulatory circuits for several of the responsive genes and demonstrate the complexity of cellular responses to genotoxic insults.

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.
