Table 1.

Our PAS patterns focus on verb and preposition predicates

No.	PAS Patterns	Examples
1	N P 1←Verb→N P 2	Protein RepA(cop) ← affects → a single amino acid
2	N P 1←Verb→b y+N P 2	Diabetes ← induced → by streptozotocin injection
3	N P 1←Verb→N P ′	Endothelin-1 (ET-1) ← had → a strong effect
	$\stackrel{\uparrow }{\mathrm{Prep.}}\to {\mathit{\text{NP}}}_2$	$\stackrel{\uparrow }{\mathit{\text{in}}}$ → all trabeculae
4	N P 1←Link. Verb→A D J P←P r e p.→N P 2	EPO receptor ← be → present ←i n→ epithelial cells
5	N P 1←Verb←P r e p.→N P 2	Apoptosis ← involved ← in → CD4 T lymphocytes
6	N P 1←Prep.→N P 2	vitronectin ← in → the connective tissue

An arrow going from a to b means that a modifies b, where a is called a predicate, and b is called an argument. <N P ₁,N P ₂> is a relevant NP pair in each pattern.
