RNA interference targeting α8 integrin attenuates smooth muscle cell growth
Bibliographic record
Abstract
alpha8 integrin gene silencing has been shown to result in the stress fibre disassembly. Stress fibres are required for cell adhesion to promote passage through cell cycle. Thus, we hypothesized that alpha8 integrin gene silencing might affect vascular smooth muscle cell (VSMC) growth. Short interference RNA (siRNA) targeting alpha8 integrin in rat VSMCs resulted in reduced DNA synthesis. Moreover, siRNA-alpha8 integrin prevented thrombin-induced proliferation. RhoA plays a critical role in regulating VSMC growth. alpha8 integrin co-immunoprecipitated with RhoA and siRNA-alpha8 reduced membrane associated RhoA. Our data suggest that alpha8 integrin expression is critical for VSMC growth, which has potential implications in postangioplasty neointimal hyperplasia.

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.
