1,2-Dichloroethane-induced hepatotoxicity and apoptosis by inhibition of ERK 1/2 pathways
Bibliographic record
Abstract
1,2-Dichloroethane (DCE) is a ubiquitous occupational environmental contaminant. Subacute exposure to DCE can cause severe toxic encephalopathy and has obvious toxic effects on the liver. However, the toxicity of DCE on the liver and its molecular mechanism remain elusive. In the present study, we established a DCE-exposed animal model by inhalation in SD rats and used HepG2 cells in in vitro tests. The DCE-exposed groups showed hepatic dysfunction relative to the control group. Moreover, apoptotic cells and decreased phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) were found in liver tissue of rats in 3 DCE-exposed groups. In vitro tests showed that short-term exposure to DCE induced apoptosis in HepG2 cells. Furthermore, the incubation of cells with DCE significantly decreased the phosphorylation of ERK1/2 in a concentration-dependent manner. Additionally, incubating HepG2 cells with epidermal growth factor, an ERK1/2 activator, significantly increased apoptosis in HepG2 cells. In conclusion, our results suggest that DCE induces apoptosis in HepG2 cells by inhibiting ERK1/2 pathways.

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.
