Integrin‐linked kinase regulates E‐cadherin expression through PARP‐1
Bibliographic record
Abstract
Repression of E-cadherin expression by the transcription factor, Snail, is implicated in epithelial to mesenchymal transition and cancer progression. We show here that Integrin-Linked Kinase (ILK) regulates E-cadherin expression through Poly(ADP-ribose) polymerase-1 (PARP-1). ILK overexpression in Scp2 cells resulted in stimulation of Snail expression and loss of E-cadherin expression. Silencing of ILK, Akt or Snail resulted in re-expression of E-cadherin in PC3 cells. To elucidate the signaling pathway downstream of ILK, we identified candidate Snail promoter ILK Responsive Element (SIRE) binding proteins. PARP-1 was identified as a SIRE-binding protein. ILK silencing inhibited binding of PARP-1 to SIRE. PARP-1 silencing resulted in inhibition of Snail and ZEB1, leading to up-regulation of E-cadherin. We suggest a model in which ILK represses E-cadherin expression by regulating PARP-1, leading to the binding of PARP-1 to SIRE and modulation of Snail expression.

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.
