Angiopoietin-1
ANGPT1proteinAngiopoietin-1 enhances endothelial barrier function and vascular stability, reducing infarct size through cardioprotection.
Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencelow
RationaleCardioprotective factor; acts on endothelial stabilization but off atherothrombotic cascade.
Also acts inEndothelial activation/erosion
Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I60
C — non-Type-I76
A — assay feasibility68
E — evidence strength34
T1DI (composite)10
Specificity differential (R−C)-16.6
Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen
