Abstract
Small heat shock proteins (shsps) are molecular chaperones that are inducible by environmental stress. In this study, immunocytochemical analysis and laser scanning confocal microscopy revealed that the shsp family, hsp30, was localized primarily in the cytoplasm of Xenopus A6 kidney epithelial cells after heat shock or sodium arsenite treatment. Heat shock-induced hsp30 was enriched in the perinuclear region with some immunostaining in the nucleus but not in the nucleolus. In sodium arsenite-treated cells hsp30 was enriched towards the cytoplasmic periphery as well as showing some immunostaining in the nucleus. At higher heat shock temperatures (35 degrees C) or after 10 microM sodium arsenite treatment, the actin cytoskeleton displayed some disorganization that co-localized with areas of hsp30 enrichment. Treatment of A6 cells with 50 microM sodium arsenite induced a collapse of the cytoskeleton around the nucleus. These results coupled with previous studies suggest that stress-inducible hsp30 acts as a molecular chaperone primarily in the cytoplasm and may interact with cytoskeletal proteins.

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 it
