Investigating the Cytotoxic and Calcium Signalling Impacts of Yellow 5 and Methyl Yellow Dyes in Mouse Nerve Cells
Bibliographic record
Abstract
The widespread use of artificial food dyes in consumables and cosmetics has raised critical concerns regarding their potential adverse effects on human health.This study evaluates the neuro-cytotoxic and calcium signaling impacts of Tartrazine (Yellow 5), a commonly used dye, and Methyl Yellow, a dye banned in the 1930s due to its toxicity.Using cultured mouse hippocampal nerve cells as a model, we assessed cell viability through Ethidium Homodimer III/Dead Red staining and fluorescence imaging after exposure to varying concentrations of Yellow 5 and Methyl Yellow.Calcium imaging with Fluo-4 revealed disruptions in calcium buffering and signaling pathways, which are critical for cellular homeostasis.These findings underscore the potential of artificial food dyes to compromise cellular function and amplify environmental stressors.In light of California's 2024 legislation banning six artificial food dyes, including Yellow 5, this study contributes new insights into food additive safety and emphasizes the necessity of rigorous oversight to safeguard consumer health.

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.
