Further, control cells were treated for 30 minutes with a NO scavenger (c-PTIO), a NOS inhibitor (7-NI) or a NADPH oxidase inhibitor (DPI) before stimulation.
NOS activity was determined using a NOS assay kit (Calbiochem, Merck, Damstadt, Germany) according to the manufacturer's instructions.
Pre-treatment with L-NAME, a NOS inhibitor, completely blocks the burst of NO production induced by sildenafil, claiming for a NOS- dependent effect.
BH4 is a NOS cofactor that is normally bound to the NOS oxygenase domain [ 19].
Second, L-arginine, the precursor of NO, had an inhibitory effect opposite to the excitatory effects a NOS inhibitor (Fig. 3E).
To test if the NO system was involved in the GH-dependent BP regulation, a NOS antagonist (L-NAME 15 mg/kg, s.c).
The amiR-ARF2 with a 35S promoter upstream and a Nos-Terminator downstream were cloned in HindIII/ EcoRI sites of a pGreenII binary vector.
The construct was expressed using a nos-gal4-vp16 driver.
A nos-Gal4 VP{UAS-imp-α2mp-α2 cDNA} chromosome was generated by meiotic recombination.
The activity of NOS was determined by a NOS Assay Kit (Sigma-Aldrich) using cardiac muscle protein extracts as described previously [ 22].
In mice, intra-hepatic synthesis of NO through the expression of a NOS-2 transgene, leads to protection from liver inflammatory injury [19].
