The Inhibition of Hsp27 Chaperone Affects the Level of p53 Protein in Tumor Cells
Bibliographic record
Abstract
The characteristics of p53 protein content in Jurkat and THP-1 tumor cell line, and mononuclear leukocytes were evaluated from in vitro studies with selective inhibition of the chaperone Hsp27. For the inhibition of Hsp27 KRIBB3 ((5-(5-ethyl-2-hydroxy-4-methoxyphenyl)-4-(4-methoxyphenyl)-isoxasole) was used. The p53 protein concentration was determined by Western blot analysis. The apoptoticly transformed cells with selective inhibitor Hsp27 were assessed by in vitro fluorescence microscopy using FITC-labeled annexin V and propidium iodide. The present study showed that the in vitro inhibition of the chaperone Hsp27 leads to an increase in p53 concentration in tumor cells and a growth of the amount of apoptotic cells in modified Jurkat and THP-1 cultures but revealed no such effects in the mononuclear leukocytes culture. Thus, Hsp27 appeared to play an important regulatory role in the activation of p53 protein of tumor cells.

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.
