Wild-type p53 suppresses formin-binding protein-17 (FBP17) to reduce invasion
Bibliographic record
Abstract
Invading tumor cells develop membrane protruding structures called invadopodia to invade and metastasize. Previously, we have reported the role of formin-binding protein-17 (FBP17) in extracellular matrix degradation and invadopodia formation in breast cancer cells. Here, we report a novel axis between tumor-suppressor p53 and FBP17. We observed that cell lines with mutant p53 express FBP17 to a higher level. The expression of FBP17 was reduced upon stabilizing wild-type p53. Furthermore, the immunohistochemistry analysis of breast cancer tissue microarrays demonstrated the correlation between the accumulation of p53 and enhanced FBP17 staining in invasive ductal carcinomas. The double knockdown of p53 and FBP17 showed the contribution of FBP17 in the invasion of cancer cells where p53 lost the regulatory control over FBP17. Taken together, these studies indicate that FBP17 may be a marker to understand the invasion propensity of breast cancer.

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.
