In their letter to the editor, Biswas and Lopes de Faria expressed concern that a recent report by Park et al. in Molecular and Cellular Proteomics [1] appears to contradict our earlier report showing that NO, but not peroxynitrite, inhibits NF
B-mediated gene activation [2]. Careful consideration of the respective studies should allay the reader's concern–there is no disagreement between data presented in these two reports. Whereas our study probes the physiological process by which NO prevents NF
B from becoming activated in vascular cells (i.e., in response to immunostimulants), Park examines how an NO-donor might turn off NF
B in a pathophysiological setting where it is
