TAT-Mediated Delivery of p27 in Tumor Cell Lines as a Potential Therapeutic Peptide
Bibliographic record
Abstract
TAT-fusion proteins (TAT-wt-p27, TAT-pt-p27, TAT-N'-p27) were introduced into the cells by protein transduction method. The mechanism by which transduced 27 influences on the regulation of cell cycle and apoptosis, were explored. TAT-p27-fusion proteins affected the proliferation of examined cell lines depending on type of the cells and protein. Transduced p27 induced accumulation of cyclin D1 and D3, with slight differences among the form of protein. Expression of cyclin D2 and E was mainly unchanged. Furthermore, TAT fusion proteins promoted apoptosis, which resulted in activation of caspase 3, appearance of poly (ADP-ribose) polymerase and DNA fragments, as well as the activation of apoptosis-inducing factor. The results pointed that transduced p27 activates apoptosis through activation of different signal transduction pathways. Thus, the molecule of p27 could be appropriate for treatment of tumors with deregulated its function. Also, the protein transduction method could find the application in specifically targeted cancer therapy.

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.
