Figure 5. Inhibition of NSmase reverts the mediator of FID back to NO in vessels from adipose tissue from patients with CAD.
A, Incubation with the specific NSmase inhibitor GW4869 (4μM, 16-20hrs) did not affect the overall magnitude of dilation to flow compared to vehicle-treated control (n=9 and 8, respectively). B, The response to flow was inhibited in CAD vessels first incubated with GW4869 in the presence of L-NAME (100μM) compared to GW4869 alone, whereas PEG-catalase (500U) had no effect (n=5, 9, and 5, respectively). *p<0.05 vs. GW4869 at specific pressure gradients.
