Anti‐angiogenic properties of opticin
Bibliographic record
Abstract
Angiogenesis plays a key role in ocular development and disease. Opticin is an extracellular matrix small leucine‐rich repeat glycoprotein which was first isolated from vitreous humour of the eye. As it is highly expressed in the eye throughout life, we hypothesised that it may contribute towards the angiogenic process. The effect of opticin on FGF‐2‐stimulated angiogenesis was determined using assays for monolayer wound recovery and boyden chamber (migration), tube‐like structure formation and invasion in matrigel or collagen gel, and examination of protein phosphorylation using Kinexus Western arrays (Bioinformatics, Canada). The presence of opticin decreased cell migration (31%, p< 0.005), tube like structure formation (37%, p<0.001) and cell invasion (45%, p<0.001). Opticin also significantly decreased the development of blood vessel formation in the chick chorioallantoic membrane assay. Opticin decreased FGF‐2‐induced phosphorylation of MEK1/2 (MAPK kinase), JNK and p38 (MAPK). A decrease of MAPKs phosphorylation is known to play crucial roles in cell migration and tubular morphogenesis. Therefore, opticin maybe an inhibitor of vascular ingression into the vitreous humour.

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.
