Insulin has been shown to elicit vasodilation through increases in nitric oxide (NO) production. To examine whether insulin may modulate the availability of tetrahydrobiopterin (BH4) (an absolute cofactor requirement for NO synthase activation), we studied the effects of insulin (150 nmol/L) on femoral arterial reactivity (to norepinephrine [NE]) in the presence and absence of 2,4-diamino-6-hydroxypyrimidine (DAHP), a specific inhibitor of BH4 production. Our data indicate that inhibition of BH4 synthesis results in an attenuation in the vasodepressor effect of insulin. One possibility is that insulin may regulate NO production by increasing cofactor (BH4) availability for activation of NO synthase.
