 Context examples: 

This gene is involved in vasoconstriction and macrophage chemotaxis.

(EDN2 Gene, NCI Thesaurus)

It has a direct antidiuretic action on the kidney, and also causes vasoconstriction of the peripheral vessels.

(Arginine Vasopressin-Neurophysin II Preproprotein, NCI Thesaurus/LocusLink)

This gene is involved in growth factor regulation and vasoconstriction.

(AVP Gene, NCI Thesaurus)

Candesartan selectively competes with angiotensin II for the binding of the angiotensin II receptor subtype 1 (AT1) in vascular smooth muscle, blocking angiotensin II-mediated vasoconstriction and inducing vasodilatation.

(Candesartan, NCI Thesaurus)

This prevents angiotensin II-induced vasoconstriction and interferes with angiotensin II-mediated aldosterone secretion, thereby decreasing aldosterone production and preventing aldosterone-stimulated sodium retention and potassium excretion.

(Olmesartan, NCI Thesaurus)

This results in arterial vasoconstriction and increased uterine smooth muscle contractions.

(Methylergonovine Maleate, NCI Thesaurus)

This prevents arterial vasoconstriction by AT II and inhibits the production of aldosterone by AT II.

(Aliskiren, NCI Thesaurus)

Alpha-adrenergic Agonists can initiate physiological responses such as vasoconstriction, pupil dilation, and contraction of pilomotor muscles.

(Alpha-Adrenergic Agonist, NCI Thesaurus)

This allele, which encodes angiotensin-converting enzyme protein, is involved in both hydrolysis and the regulation of vasoconstriction.

(ACE wt Allele, NCI Thesaurus)

Phenoxybenzamine non-selectively and irreversibly blocks the postsynaptic alpha-adrenergic receptor in smooth muscle, thereby preventing vasoconstriction, relieving vasospasms, and decreasing peripheral resistance.

(Phenoxybenzamine, NCI Thesaurus)
