Activation of nuclear factor-κB (NF-κB) by increased production of reactive oxygen species (ROS) might induce transcription and expression of different antioxidant enzymes and also of nitric oxide synthase (NOS) isoforms.
Thus, we aimed at studying the effect of NF-κB inhibition, caused by JSH-23 (4-methyl- N 1 -(3-phenyl-propyl)-benzene-1,2-diamine) injection, on ROS and NO generation in hereditary hypertriglyceridemic (HTG) rats.
12-week-old, male Wistar and HTG rats were treated with JSH-23 (bolus, 10 μmol, i.v.).
After one week, blood pressure (BP), superoxide dismutase (SOD) activity, SOD1, endothelial NOS (eNOS), and NF-κB (p65) protein expressions were higher in the heart of HTG rats compared to control rats.
On the other hand, NOS activity was decreased.
In HTG rats, JSH-23 treatment increased BP and heart conjugated dienes (CD) concentration (measured as the marker of tissue oxidative damage).
Concomitantly, SOD activity together with SOD1 expression was decreased, while NOS activity and eNOS protein expression were increased significantly.
In conclusion, NF-κB inhibition in HTG rats led to decreased ROS degradation by SOD followed by increased oxidative damage in the heart and BP elevation.
In these conditions, increased NO generation may represent rather a counterregulatory mechanism activated by ROS.
Nevertheless, this mechanism was not sufficient enough to compensate BP increase in HTG rats.
